Vendor & Third-Party Risk Controls for Cloud Readiness

Inventorying subprocessors, DPAs, SOC reports, and continuous monitoring for third-party risk.

Why this matters

A cloud security readiness audit is the fastest way to find the gaps that would otherwise fail a certification, break a customer deal, or surface during an incident. This guide covers what to prepare, how auditors evaluate the evidence, and the common pitfalls that turn a two-week engagement into a two-month scramble.

What auditors are looking for

• A documented control set mapped to a recognized framework (SOC 2, ISO 27001, CIS, NIST 800-53).
• Evidence that the control is designed correctly — policy, standard, or configuration.
• Evidence that the control operated over the review window — logs, tickets, screenshots, or exports.
• Ownership — a named team or role responsible for the control.

If any of the four is missing, the finding is written up. Design-only controls (no operating evidence) are the single most common gap we see.

Core areas covered in a readiness audit

1. Identity and access management
2. Network and perimeter controls
3. Logging, monitoring, and alerting
4. Data protection and encryption
5. Vulnerability and patch management
6. Change management and SDLC
7. Incident response and business continuity
8. Vendor and third-party risk
9. Human resources and security awareness
10. Physical and environmental (cloud provider inheritance)

How to prepare

Start with an asset inventory — accounts, subscriptions, projects, and the crown-jewel workloads inside them. Without an accurate inventory the rest of the audit collapses. Layer the control matrix on top, then assign an owner per control. Pull automated evidence (CloudTrail, Config, Security Hub, Defender for Cloud, SCC) into a single evidence workspace so the auditor is not chasing you for artifacts.

Common pitfalls

• Treating readiness as a documentation exercise instead of a technical one.
• Waiting for the auditor to define scope instead of defining it yourself.
• Screenshot-only evidence with no timestamp or approver.
• Root account still receiving alerts to a shared inbox.
• Terraform in one repo, production drift everywhere else.

Next step

A properly scoped readiness audit runs in 3–6 weeks and gives you a prioritized remediation plan you can hand to engineering. If you want a second set of eyes on your control set before the auditor arrives, that is exactly what we do at Razr.
