About this Gig
Vetted Pro
Someone who left last year can probably still sign in.
Access is easy to grant and nothing takes it away. After a few years of hiring and moving, nobody can say who can reach what, and that is exactly what customers now ask.
You are probably here because
- A customer or auditor asked who has access and you could not answer
- People changed role and kept everything they had before
- Almost everyone has admin rights, just in case
What you get
- A clear picture of who can reach what today, in plain language
- The accounts and permissions putting you at risk, ranked
- What to change, and the order to change it in
- A live call where I walk your team through it
How it works
- You tell me what systems people log into. No docs needed
- I review how access is granted, used and removed
- You get the findings and we go through them together
What you can count on
Read access is enough. Nothing is changed or disrupted, and you never send me a password.

FAQ
Is this a penetration test or technical exploit assessment?
No. This project is a structured IAM security and access governance review. The focus is on identifying risks, control gaps, governance weaknesses, and practical improvement opportunities.
Which IAM platforms can you review?
I can review environments involving Entra ID, Active Directory, Okta, Google Workspace, AWS IAM, federated identity setups, SaaS access models, and similar IAM-related platforms in scope.
Do I need to provide architecture or access documentation?
A diagram or written summary is strongly recommended because it improves the quality and speed of the review. If formal documentation is limited, a structured written overview is usually enough to start.
What will I receive at the end of the project?
Depending on the package, you may receive an executive summary, findings report, prioritized risks, governance improvement roadmap, and practical IAM recommendations.
Is this useful for audit or compliance preparation?
Yes. While this is not a formal certification audit, it is very useful for identifying IAM control gaps, improving governance maturity, and supporting readiness for frameworks such as ISO, NIST, SOC 2, PCI DSS, and similar requirements.
