Securing Global Multi-Cloud Governance at Scale
Overview
THE CHALLENGE
The client faced fragmented cloud governance across AWS, Azure, and GCP, with 490+ accounts lacking automated security guardrails and no unified ownership model.
THE SOLUTION
Ollion partnered with cross-functional teams to build a scalable Cloud Security Operating Model, implementing automated guardrails, compliance workflows, and multi-cloud security enforcement using Kion and Wiz CSPM.
THE OUTCOME
The client achieved unified cloud governance, automated security enforcement, improved compliance visibility, a roadmap to secure 490+ accounts, and identified $624K in annual cloud savings.
About the Business
The client is a Tier-1 global cybersecurity vendor specializing in advanced identity security and access management solutions. Their platform goes beyond standard credential management to map, monitor, and secure complex access pathways across enterprise environments to neutralize internal and external threats. Operating at massive scale, the organization protects over 20,000 customers across more than 100 countries, including three-quarters of the Fortune 100 companies.
The Business Challenges
Operating a massive, highly complex multi-cloud estate spanning AWS, Azure and GCP, the client possessed a strong commitment to security but lacked the operational framework to back it up. A series of deep-seated structural governance gaps meant that critical security policies were at risk.
- Fragmented Ownership: Nine governance activities were scattered across three separate organizations (CISO, CTO, and CFO) without a single-named owner to bridge the gaps.
- Account Risk: More than 490+ non-production accounts lacked preventive guardrails, leaving them highly exposed.
- Manual Drift: Translating high-level policies into functional technical controls was entirely manual, undocumented, and prone to severe configuration drift.
- Silent Violations: With zero security gates embedded in the CI/CD pipeline, policy violations routinely slipped into production completely unblocked.
The Ollion Solution
IT Services and Consulting firms in our industry are known for big promises and heavy frameworks handed down from the outside. Ollion takes a different route. We went all in with the Client’s teams, working alongside 28 key stakeholders across Engineering, Security, Cloud Ops and FinOps to design an operating model built for the real world.
Co-Creating the Operating Model
We ran deep-dive sessions to map the client's full governance lifecycle and build a comprehensive Security Operating Model. This wasn't a conceptual strategy document, it was a blueprint that aligned people, processes, and technology. We established clear accountability across 13 core activities, mapped out a structured, automated exception workflow, and established an open feedback loop from runtime violations back to the policy layer.
From Strategy to Production Reality
We don't stop at advice; we build solutions you can actually run. Ollion delivered a production-ready cloud governance architecture that put the new operating model directly to work:
Automated Guardrails
We deployed cloud-native, preventive enforcement across the entire multi-cloud ecosystem, using Kion to orchestrate and automate policy states across 490+ accounts, paired with Wiz CSPM for cross-cloud risk visibility.
Proven in Production
We authored and successfully enforced the client's primary network control across 10 pilot accounts, establishing a clear, phased rollout plan for the rest of the estate.
Found Savings
While tightening security, our cloud economics team uncovered massive optimization opportunities across CloudWatch, EFS cold storage, idle volumes, and S3 tiering.
The Business Benefits
By focusing on practical execution rather than theoretical frameworks, we didn't just hand over a deck—we transformed how the client operates
100% Accountability Secured
Eradicated all previous ownership gaps by establishing a newly approved, 13-activity organizational model and a live compliance dashboard.
10 Production Accounts Fully Enforced
Successfully deployed and validated the foundational security guardrail in live environments before program close.
490+ Accounts Map to Scale
Provided the team with a clear, phased roadmap to bring every remaining non-production account under automated governance.
$625K in Annual Savings Identified
Uncovered up to $52,000 per month in immediate, recoverable cloud spend to actively fund future innovation.
The One Big Thing
The Cloud Security Operating Model provides a repeatable, unified standard to govern a zero-trust ecosystem. By breaking down organizational silos, the client now enjoys continuous monitoring, a hardened security posture, and the structural agility to change for good.
"Every gap Ollion found was validated by the people closest to the work. The operating model was designed with our teams, not handed down to them. They didn't just give us a strategy—they gave us governance we can actually run, and a true partnership that set us up to succeed on our own."
