87% of Companies Run Multi-Cloud. Almost None Have Solved the IAM Problem That Makes It All Vulnerable.
Picture this scenario, which is far more common than any CISO would want to admit.
A large Indian BFSI enterprise runs AWS for its core banking APIs, Azure for its Microsoft 365-integrated applications, and maintains a private data center in Mumbai for regulated workloads. Each environment has its own identity plane. Developers have separate credentials for each cloud. Service accounts created during a migration project two years ago still exist; and still have broad permissions. A contractor who left the organization six months ago technically still has active credentials in one environment because offboarding only covered two of the three platforms.
Nobody has deliberately created this exposure. Everyone followed their organization’s security policies for each individual environment. And yet the aggregate result is a fragmented identity landscape that any moderately sophisticated threat actor can exploit simply by finding the weakest link in a chain that nobody is monitoring as a whole.
This is the identity crisis at the heart of Indian hybrid cloud security. And it isn’t a fringe problem; it is the dominant attack vector in cloud environments today.
The 87% Problem: Why Multi-Cloud Adoption Has Outrun Multi-Cloud Security
87% of companies now run a multi-cloud strategy (Flexera State of the Cloud 2024). In India specifically, the numbers are even more striking: large enterprises in BFSI, telecom, ed-tech, and manufacturing have moved aggressively to multi-cloud and hybrid architectures, driven by cost optimization, regulatory requirements, and the need for geographic redundancy.
The problem is that this adoption has been primarily driven by technology teams optimizing for performance, cost, and capability – not security teams optimizing for unified governance. The result is a landscape characterized by what researchers describe as “inconsistent security policies across different cloud platforms, increased vulnerability to data breaches due to expanded attack surfaces, and difficulties in implementing unified identity and access management (IAM) systems” (Julakanti et al., NeuroQuantology 2022).
That’s the academic framing. Here’s the operational reality: your security team is trying to enforce governance across three cloud environments that each speak a different identity language, use different policy models, have different audit log formats, and require separate management interfaces. The sheer cognitive and operational load of this fragmentation is, itself, a security vulnerability; because humans under sustained operational pressure make mistakes, skip steps, and inevitably miss things.
The Indian enterprise C-suite has largely treated this as a tool procurement problem: buy more security products, add more monitoring. But the core issue isn’t the absence of tools. It’s the absence of a unified governance architecture that operates across hybrid cloud boundaries – not within them.

Why Traditional Security Frameworks Are Failing Hybrid Cloud India
Before prescribing solutions, it’s worth being honest about why organizations keep reaching for traditional security frameworks and finding them insufficient.
The NIST Cybersecurity Framework, ISO/IEC 27001, and the Cloud Security Alliance Cloud Controls Matrix (CCM) are all respected, comprehensive frameworks. They provide excellent guidance on security domains, control objectives, and implementation requirements. And they were designed for a world where “the network perimeter” was a meaningful concept that security controls could protect.
In a hybrid cloud environment, the network perimeter doesn’t exist. Your data moves between AWS Mumbai, Azure India Central, an on-premises data center, and your employees’ devices – continuously, dynamically, and often through connections that no single security tool is monitoring end-to-end.
The research is unambiguous on this: “many security frameworks are tailored to single-cloud deployments and may not seamlessly integrate across multiple platforms. Traditional security solutions often lack the interoperability and scalability required to manage the diverse and distributed nature of multi-cloud infrastructures” (Julakanti et al., NeuroQuantology 2022).
For Indian compliance officers specifically, this creates a particularly uncomfortable position. You’re being asked to demonstrate compliance with DPDP Act requirements, RBI guidelines, SEBI cloud circulars, and IRDAI regulations; each with specific requirements around data residency, access controls, audit logging, and breach notification – using frameworks and tools that were designed before this regulatory environment existed.
The compliance gap between what regulations require and what traditional frameworks can verify in a hybrid cloud context is not a paperwork problem. It’s a technical architecture problem.

The Eight Challenges Nobody Tells You About Before You Go Hybrid
The research on hybrid cloud security challenges tends toward theoretical categorizations. What’s more useful for Indian CISOs is an honest operational inventory of what these challenges actually feel like when you’re managing them daily.
1. Unified Security Management Across Incompatible Platforms
Developing a centralized security management system that can enforce consistent policies across AWS, Azure, GCP, and on-premises environments simultaneously is genuinely, substantively hard. Each platform has its own policy model, its own syntax for security rules, and its own concept of what “compliant” means. A change made in one environment doesn’t propagate to others. A violation detected in one console doesn’t appear in another. And your security team is the manual bridge between all of these disconnected systems (Julakanti et al., NeuroQuantology 2022).
2. IAM Coherence Across Cloud Boundaries
Managing user identities, service accounts, machine identities, and permissions consistently across multiple cloud platforms is the operational equivalent of maintaining a single phone book for three separate cities that each use different numbering systems. Federated identity helps – but only if it’s implemented completely, which most organizations haven’t achieved. In the gaps, overprivileged accounts, stale credentials, and inconsistent RBAC configurations accumulate like sediment, creating privilege escalation paths that are invisible to any single-cloud security tool.
3. Data Protection Across Jurisdictional Boundaries
Data sovereignty is a compound problem in Indian hybrid cloud deployments. Personal data processed under the DPDP Act has specific residency requirements. Financial data processed under RBI guidelines has its own requirements. Healthcare data under the Draft Digital Health Data Management Policy has yet others. And in a multi-cloud architecture where data flows between environments continuously, ensuring that the right data stays in the right geography; with the right protections – requires automated policy enforcement rather than manual verification.
4. Real-Time Threat Detection Across Fragmented Event Streams
Detecting threats in real time across multiple cloud environments requires aggregating and correlating event logs from sources that each use different schemas, different sampling rates, and different retention policies. Without a unified detection plane, threat patterns that span environments – the attacker who compromises AWS IAM credentials and pivots to Azure storage – are invisible. By the time a human analyst correlates the evidence manually, the breach is complete and the exfiltration is done.

5. Compliance Management Across Multiple Regulatory Regimes
Indian enterprises are routinely subject to four to six concurrent regulatory frameworks with overlapping but non-identical requirements. Demonstrating compliance with each simultaneously, across multiple cloud platforms, requires either massive compliance team overhead or automation. Most organizations are doing this manually, which means their compliance posture at any given moment is a snapshot from the last audit cycle – not a real-time reflection of their actual configuration state.
6. Vendor Lock-In and Interoperability Constraints
Building your security architecture around any single cloud provider’s native security tooling creates a dependency that limits your ability to evolve your cloud strategy. If your security visibility is provided entirely by AWS Security Hub, moving workloads to Azure is simultaneously a business decision and a security visibility gap creation event. True hybrid cloud security requires platform-agnostic governance that remains effective regardless of which provider a workload runs on.
7. Resource Sprawl and Shadow IT Governance
In large Indian enterprises, particularly those that adopted cloud rapidly during the pandemic period, resource sprawl is endemic. Development teams, analytics teams, and business units all provisioned cloud resources independently, often without central IT oversight. The result is an estate with hundreds of accounts, thousands of resources, and an unknown number of sensitive data repositories that exist outside any formal data classification or security governance program.
8. Incident Response Coordination Across Platforms
When a security incident spans multiple cloud environments – and increasingly, they do – coordinating response efforts requires a unified view of the incident timeline, the affected resources across all environments, the data that may have been exposed, and the remediation steps required in each platform. Without this unified view, incident response is slower, less precise, and more expensive than it needs to be.

Zero Trust: Not a Product, a Philosophy – And Why Indian Enterprises Get It Backwards
Zero Trust has become one of the most misunderstood concepts in enterprise cloud security.
Both framings miss the point. Zero Trust is an architectural philosophy, not a product. Its core premise – verify explicitly, use least privilege access, assume breach; is a design principle that must be embedded into how you build and operate every system, not a feature set you enable on a single security appliance.
For Indian enterprises navigating hybrid cloud environments, Zero Trust has five practical implications that are worth understanding precisely:
Verify Explicitly
Means every access request; whether from a human user, a service account, or a machine identity – is authenticated and authorized based on all available signals: identity, location, device health, service, workload, and data classification. Not once at login, but continuously. An employee who authenticates successfully in the morning and then exhibits unusual behavior at 3 PM (exfiltrating large volumes of data, accessing systems outside their normal pattern) should be challenged and potentially suspended automatically, not trusted until they log out.
Use Least Privilege Access
Means every identity – human or machine; operates with the minimum permissions required to perform its specific function. Not “enough permissions to do the job plus some extra for flexibility.” Exactly the permissions required, for exactly the duration required, with automatic expiration. In hybrid cloud environments, where service accounts frequently accumulate permissions through the path of least resistance (“add FullAccess rather than figure out the exact policy”), enforcing least privilege at scale requires automated detection of over-permissioned identities and automated remediation.
Assume Breach
Means designing your security architecture as if the perimeter has already been compromised; because in a hybrid cloud environment, it has been, in the sense that there is no meaningful perimeter. Network segmentation and micro-segmentation are the operational expression of this principle: even if an attacker has compromised one workload, they should not be able to freely traverse the network to reach other workloads or data stores.
Continuous Monitoring
Means that Zero Trust is not a state you achieve and maintain – it’s a process you execute continuously. User behaviors change. Application behaviors change. Configurations drift. New resources are provisioned. Each of these is a potential change to the risk profile that your security architecture must respond to in real time.
Automate Everything Enforceable
Means that Zero Trust principles cannot be operationalized manually at the scale of a modern Indian enterprise cloud environment. Policy enforcement, identity governance, anomaly detection, and incident response must be automated wherever possible, with human judgment reserved for the genuinely complex decisions that automation cannot resolve reliably.
The Compliance-First Framework: Mapping DPDP Act to Hybrid Cloud Security Controls
For Indian CISOs and Data Privacy Officers navigating DPDP Act compliance in hybrid cloud environments, the most valuable exercise is mapping the Act’s specific requirements to the technical security controls that satisfy them. Here is that mapping:
| DPDP Act Requirement | Technical Security Control | Implementation in Hybrid Cloud |
|---|---|---|
| Technical and organizational measures for personal data security | CSPM continuous policy enforcement + encryption at rest/in transit | Automated policy checks across all cloud environments, centralized key management via AWS KMS / Azure Key Vault / GCP KMS |
| Access controls for personal data | Unified IAM with RBAC, MFA, least privilege | Federated identity across clouds, automated access reviews, just-in-time access provisioning |
| Breach detection and 72-hour notification | SIEM cross-cloud threat detection | Unified event correlation with automated alerting and incident timeline generation |
| Data residency for Significant Data Fiduciaries | Data location monitoring and policy enforcement | Automated detection of data flows crossing residency boundaries, policy blocking cross-region replication |
| Audit logging and evidence of compliance | Centralized audit log management | Immutable log storage across all cloud environments, automated compliance report generation |
| Data processor obligations | Cloud provider security configuration verification | CSPM continuous verification that cloud configurations implement contractual data protection requirements |
| Data minimization and purpose limitation | Data classification and access governance | Automated data discovery, classification tagging, and access controls based on sensitivity classification |
This mapping makes visible something that many organizations are discovering the hard way: DPDP compliance in a hybrid cloud environment is fundamentally a security architecture question, not a legal documentation question. The 72-hour breach notification requirement, in particular, is only achievable with automated detection—no organization can manually discover, investigate, scope, and notify in 72 hours without the right technical infrastructure in place.

Legacy vs. Modern Multi-Cloud Security: The Architecture That Changes Everything
The difference between organizations that successfully manage hybrid cloud security and those that perpetually struggle with it isn’t budget or headcount. It’s architecture. Here’s what the two models actually look like in practice:
| Capability | Legacy Fragmented Approach | Modern Unified Approach |
|---|---|---|
| Security visibility | Per-cloud consoles, manual correlation | Single unified view across all environments |
| IAM governance | Separate identity systems per cloud, manual reconciliation | Federated identity, automated cross-cloud RBAC, continuous access reviews |
| Compliance monitoring | Point-in-time audits, manual evidence collection | Continuous automated compliance monitoring, real-time dashboards |
| Threat detection | Per-cloud alerts, siloed investigation | Cross-cloud event correlation, unified incident timeline |
| Policy enforcement | Manual configuration, platform-specific policies | Automated policy-as-code, cross-cloud enforcement |
| Incident response | Manual coordination across platforms | Unified playbooks, automated containment across clouds |
| Audit preparation | Weeks of manual evidence assembly | On-demand automated report generation |
| Data residency compliance | Manual checks, periodic verification | Continuous automated monitoring, policy-based enforcement |
| Zero Trust implementation | Aspirational, partially implemented | Enforced continuously through automated controls |
| DPDP Act readiness | Partial, documentation-heavy | Technical controls continuously verified and documented |
The organizations operating from the right column are not running more security tools. They’re running a fundamentally different architecture – one where unified governance is the foundation and cloud-specific tools are the implementation layer, not the governance layer.
From Compliance Overhead to Compliance Advantage: The BFSI Case
Indian BFSI organizations face the most complex compliance landscape of any sector: DPDP Act, RBI guidelines on cloud computing, SEBI cloud circular, PCI-DSS for payment card data, ISO/IEC 27001 for information security management, and increasingly, SWIFT Customer Security Programme requirements for international transactions.
Managing compliance with this matrix manually is not just expensive; it creates a compliance program that is perpetually behind, always preparing for the last audit rather than continuously demonstrating adherence to current requirements.
The organizations that have shifted from compliance overhead to compliance advantage have done so by treating their security architecture as their compliance infrastructure. When your CSPM is continuously monitoring every cloud configuration against regulatory frameworks, when your SIEM is generating audit-ready event logs across all environments, when your IAM is enforcing least privilege and generating access reviews automatically – your compliance evidence exists continuously, not just at audit time.
This shift has practical business consequences. Security certifications become competitive differentiators in procurement processes where enterprise customers require demonstrated compliance. Audit cycles become confirmations of continuous compliance rather than multi-week preparation marathons. Regulatory examinations become opportunities to demonstrate your governance program rather than existential events requiring emergency remediation.
For Indian BFSI CISOs, the question is not whether to pursue this architecture but how quickly they can get there before the DPDP Act’s full enforcement regime in 2027 makes the current fragmented approach operationally untenable.
How Ion Closes the Hybrid Cloud Governance Gap
Cy5’s Ion Cloud Security Platform was architected specifically to address the governance gap that emerges when organizations try to manage hybrid cloud environments with tools designed for single-cloud or on-premises architectures.
Unified Visibility That Doesn’t Require Integration Projects
Ion ingests security telemetry from AWS, Azure, and GCP simultaneously through event-driven architecture, providing a single governance view without the multi-month integration engineering that traditional SIEM deployments require. Security teams work from one console with normalized data rather than maintaining expertise in three separate cloud consoles.
Contextual Identity Risk Scoring
Ion analyzes identity risk across cloud boundaries – mapping granted permissions against permissions in use, flagging identities with access keys, no MFA, or never-used permissions that represent unnecessary attack surface. This isn’t static IAM analysis; it’s continuous identity risk monitoring that surfaces the exact over-permissioned accounts and stale credentials that manual IAM reviews consistently miss.
Toxic Combination Detection for Hybrid Environments
Ion’s contextual correlation engine identifies the configurations that are dangerous not in isolation but in combination: public network access plus overly permissive compute plus full IAM access equals a breach waiting for an attacker to find it. In hybrid environments where these combinations can span cloud providers, Ion’s cross-cloud correlation is the only mechanism that makes them visible.
DPDP-Ready Compliance Automation
Ion’s continuous compliance monitoring maps security configurations to regulatory requirements continuously, generating audit-ready evidence and real-time compliance dashboards that eliminate the manual evidence assembly that characterizes traditional compliance programs. For organizations facing DPDP Act obligations, this is the technical foundation for demonstrating continuous adherence rather than point-in-time compliance.
Event-Driven SIEM That Eliminates the Notification Window
For DPDP Act breach notification obligations, Ion’s event-driven detection eliminates the detection blind spots created by scheduled-scan architectures. Real-time event ingestion and cross-cloud correlation mean that cross-environment attacks are detected as they unfold, not hours later when the next scan cycle runs.
The business outcomes from Indian enterprise deployments:
| Metric | Result |
|---|---|
| Alert noise reduction (FinTech) | 85% reduction |
| Alert noise reduction (Other sectors) | 96% reduction |
| MTTD reduction (Telecom) | 97% improvement |
| Onboarding time | <24 hours |
| Security team time saved (annual) | 3 man-months |
| Customer retention rate | 100% |
The Six Recommendations for Indian Enterprise Hybrid Cloud Security in 2025-2026
Based on the research findings and operational experience with Indian enterprise multi-cloud environments, here is the prioritized action framework for CISOs navigating hybrid cloud governance:
1. Adopt a Centralized Security Platform, Not a Tool Collection
The highest-leverage decision is architectural: choose a platform that provides unified visibility and governance across all cloud environments rather than adding point tools to each environment independently. The integration overhead and governance gap created by fragmented tools compounds over time; the sooner you address the architecture, the cheaper the long-term security program (Julakanti et al., NeuroQuantology 2022).
2. Make IAM the First Unification Priority
Before unifying compliance monitoring, threat detection, or policy enforcement, unify identity governance. A federated identity model with SSO, MFA enforcement, RBAC standardization, and continuous access reviews across all cloud environments is the foundational control that makes every other security control more effective. An attacker who cannot obtain or abuse a valid identity cannot breach your environment regardless of what vulnerabilities exist in the configuration layer.
3. Automate Compliance Evidence Collection Immediately
With DPDP Act enforcement approaching full implementation in 2027, the organizations that invest now in automated compliance monitoring and evidence collection will have a structural advantage in audit readiness. Those that continue manual evidence assembly will face progressively more expensive compliance programs as the regulatory surface area grows.
4. Implement Zero Trust Incrementally, Not as a Project
Zero Trust is not a transformation project with an end date. It’s a set of principles you embed progressively into your security architecture. Start with MFA everywhere, then least privilege access reviews, then continuous identity verification, then network micro-segmentation. Each increment reduces risk meaningfully; you don’t need to wait for complete implementation to realize value.
5. Address Shadow IT Before It Addresses You
Conduct an automated asset discovery across all cloud accounts and regions to identify resources that exist outside your formal governance program. Every shadow resource is an unmonitored attack surface. Every unmonitored attack surface is an incident waiting to happen. This is not a one-time exercise; it requires continuous automated discovery because shadow resources are continuously being created.
6. Build Incident Response Plans That Span Cloud Boundaries
Your incident response plans were probably written when most of your infrastructure was on-premises or in a single cloud. Update them to account for cross-cloud incidents: who is responsible for containing a threat that spans AWS and Azure simultaneously? What’s the communication protocol with multiple cloud providers during an active incident? How does your 72-hour DPDP notification clock work when the investigation spans three platforms? These questions need answers before an incident, not during one.
Frequently Asked Questions: Hybrid Cloud Security and IAM for Indian Enterprises
The most impactful practices for Indian BFSI multi-cloud security are:
(1) unified IAM with federated identity across all cloud platforms, enforcing MFA and least privilege;
(2) continuous compliance monitoring mapped to DPDP Act, RBI guidelines, and PCI-DSS simultaneously;
(3) cross-cloud SIEM with event-driven threat detection for 72-hour breach notification readiness;
(4) automated data residency monitoring for personal data; and
(5) Zero Trust architecture implemented progressively across all access points.
Organizations pursuing compliance-first architectures consistently demonstrate superior security outcomes and audit readiness compared to tool-centric approaches.
Zero Trust in hybrid cloud environments means applying verify-explicitly, least-privilege, and assume-breach principles at every access point regardless of whether the resource is in AWS, Azure, GCP, or on-premises. In practice, this requires federated identity that authenticates every access request with full context (not just credentials), continuous monitoring of all identity and resource activity across cloud boundaries, and automated enforcement of least-privilege policies that cover all cloud environments simultaneously. Zero Trust is not a product; it’s a design principle embedded progressively into hybrid cloud architecture.
DPDP Act compliance automation in multi-cloud environments requires:
(1) CSPM continuously monitoring technical security controls against DPDP requirements across all cloud environments;
(2) automated audit log collection and immutable storage for breach investigation and regulatory evidence;
(3) real-time data residency monitoring that detects and prevents personal data from crossing jurisdictional boundaries;
(4) access control automation enforcing DPDP’s purpose limitation and data minimization requirements; and
(5) automated breach detection enabling the 72-hour notification obligation.
Organizations that implement these controls through unified platforms rather than cloud-specific tools achieve compliance readiness that persists between audit cycles rather than being assembled for them.
Reducing lateral movement in hybrid cloud environments requires network micro-segmentation at the workload level, Zero Trust network access controls that restrict communication between services to explicitly authorized paths, and continuous monitoring of network traffic for anomalous lateral movement patterns. The specific controls include enforcing egress filtering at the workload level, implementing east-west traffic inspection between cloud environments, applying Zero Trust principles to service-to-service communication (not just user access), and using behavioral analytics to detect lateral movement patterns that don’t trigger signature-based detection rules.
Multi-cloud security manages risk across multiple public cloud providers (AWS, Azure, GCP) simultaneously. Hybrid cloud security additionally encompasses on-premises infrastructure that coexists with cloud environments – including private data centers, colocation facilities, and legacy systems that connect to cloud platforms. Hybrid cloud security is generally more complex because it must bridge the security models of both traditional on-premises security (network perimeter, hardware-based controls) and cloud-native security (API-driven, software-defined). In practice, most Indian enterprises run hybrid environments that require security architectures addressing both dimensions simultaneously.
Unified IAM reduces cloud security risk through several compounding mechanisms: eliminating the stale credentials and orphaned accounts that accumulate when offboarding covers only some cloud environments; enforcing consistent least-privilege policies that don’t have platform-specific gaps; providing continuous visibility into privileged access activity across all cloud environments simultaneously; enabling automated access reviews that don’t require manual coordination across multiple systems; and reducing the privilege escalation paths that emerge when IAM policies are inconsistent across cloud boundaries. Research consistently identifies identity compromise as the most common initial access vector in cloud breaches – unified IAM is the direct mitigation for this risk.
Indian enterprises operating hybrid cloud environments should align with: ISO/IEC 27001 (information security management, widely recognized by Indian regulators), ISO/IEC 27017 (cloud-specific security controls extending 27001 for cloud deployments), NIST Cybersecurity Framework (risk-based approach applicable across on-premises and cloud), Cloud Security Alliance Cloud Controls Matrix (CCM) (cloud-specific security controls mapped to major regulatory frameworks), and India-specific requirements including DPDP Act 2023 Rules, RBI cloud computing guidelines, and SEBI circular on cloud adoption. No single framework is sufficient for Indian hybrid cloud environments; a composite approach mapped to your specific regulatory obligations is required.
Conclusion: The Identity You Don’t Manage Becomes the Attack Path You Don’t See
The hybrid cloud security problem is fundamentally an identity governance problem – and that’s both the bad news and the good news.
The bad news: identity fragmentation across hybrid cloud environments creates attack paths that are invisible to any single-cloud security tool, accumulate through normal operational processes, and compound in complexity every time a new cloud service is adopted.
The good news: identity governance is architecturally solvable. Federated identity, unified IAM, Zero Trust principles applied continuously, and automated compliance monitoring – implemented as a coherent architecture rather than a collection of point tools – close the governance gap that attackers currently exploit.
For Indian enterprises, the urgency is compounded by DPDP Act obligations that will require demonstrated continuous compliance, not point-in-time certification. The organizations that build unified hybrid cloud governance now will be ahead of regulatory requirements when full enforcement begins. Those that continue accumulating technical security debt in fragmented architectures will face a much harder and more expensive path to compliance when that deadline arrives.
The identity crisis is solvable. The question is when you choose to solve it.
