Problem briefing
Every identity is over-permissioned and every fix might break payroll.
CIEM tools are very good at telling you which permissions are unused. Compare the vendors on who will right-size the role without taking a business system down.
> 90%
Granted cloud permissions that typically go unused
Weeks
Time to safely right-size a single load-bearing role by hand
1 outage
All it takes for identity remediation to be frozen for a year
You are here if
- Your unused-permission report has not been actioned in two quarters
- Nobody will approve a role change without an owner who does not exist
- Service accounts with admin rights are documented as accepted risk
- Least privilege is a policy statement, not an observed state

Where Tamnoon leads: Tamnoon sequences identity changes with a human owner and a rollback path, which is the difference between a CIEM report and an actually smaller blast radius.

Our pick: Tamnoon
Tamnoon leads because right-sizing identity is judgement work. Usage data tells you what can probably be removed; a human accountable for the change is what makes anyone willing to remove it.
Ask every vendor on your shortlist
- How long an observation window do you use before recommending a cut?
- Do you stage changes behind a monitored dry-run?
- Who is accountable if a right-sized role breaks a production job?
- How do you handle identities with no named owner?
- Can you show sequenced remediation, not a one-shot bulk change?
Questions we get asked
- Why do CIEM findings stay open so long?
- Because the fix carries production risk and the reward is invisible. Without someone owning the change and its rollback, the rational move for any engineer is to leave it alone.
- Can permission right-sizing be fully automated?
- Removing clearly dead permissions can be. Anything load-bearing needs staged rollout and a human who can read the usage evidence in business context.
- Where should an identity programme start?
- Unused admin-equivalent permissions on non-human identities. High blast-radius reduction, low chance of business disruption, easy to evidence.
