Thibaut Tauveron · Cloud & IAM Architecture for Regulated Environments

I help regulated organizations build audit-ready cloud platforms with pragmatic security and access governance.

Structured security engagements that clarify risk and accelerate execution.

When I typically get involved

Preparing for audit or external assessment where cloud and access traceability are under active scrutiny
IAM/RBAC has grown organically and no longer provides clear accountability or audit defensibility (privilege sprawl, unclear ownership)
Cloud platform requires exposure reduction and enforceable security baselines aligned with regulatory expectations (logging, segmentation, identity boundaries)
Teams need a pragmatic, engineering-executable plan (not a policy-only exercise).

Selected outcomes

Reduced structural access risk through JIT access model

Designed and implemented a just-in-time access lifecycle across web applications, Kubernetes, and databases to improve traceability and auditability.

Access model aligned with FINMA supervisory expectations

Rebuilt IAM/RBAC architecture in a regulated cloud banking environment to meet supervisory and audit requirements.

Six-figure annual savings without degrading controls

Optimized cloud usage, logging, and DR trade-offs while maintaining security posture and compliance requirements.

Structured engagements

Short, defined engagements designed to clarify risk and accelerate execution.

IAM & Access Governance Alignment Sprint

4–6 weeks

When privilege sprawl, unclear RBAC ownership, or weak governance create structural access risk.

Target-state IAM/RBAC architecture (least privilege and JIT access model)
Access lifecycle + governance framework
Implementation plan and sequencing

Deliverables: target-state IAM architecture + governance model + phased implementation plan.

Can extend into rollout support and control hardening.

Cloud & IAM Risk Diagnostic

3–4 weeks

When audit pressure is increasing or leadership needs a clear view of cloud and access risk.

Architecture and identity model review
Privilege exposure assessment aligned with audit expectations
Prioritized remediation roadmap

Deliverables: executive risk summary, prioritized roadmap, and target-state recommendations.

Can extend into remediation or delivery support.

Secure Cloud Architecture Review

2–3 weeks

When rapid growth, migration, or regulatory scrutiny requires stronger cloud security foundations.

Landing zone + segmentation review
Exposure reduction quick wins
Security baseline validation and roadmap

Deliverables: architecture findings + prioritized quick wins + target-state roadmap.

Can extend into focused remediation sprint.

How I work

Initial discovery discussion to clarify scope, constraints, and success criteria.
Weekly checkpoint and concise written status update covering progress, key risks, and decisions.
Practical, implementation-ready deliverables: target architecture, access model, and execution roadmap.

Technical depth

Hands-on architecture and delivery across cloud-native platforms, with strong focus on identity, access control, and security posture in regulated environments. Experience designing IAM/RBAC models, Zero Trust access patterns, and infrastructure-as-code based platforms, aligned with supervisory and audit expectations.
