Twice a year, in many enterprises, a spreadsheet goes out. It lists hundreds of entitlements per manager, described in system-internal jargon, and asks each manager to certify that every one is still appropriate. The managers, facing a deadline and a wall of rows they cannot interpret, approve nearly everything. The exercise is filed as evidence of access governance. Everyone involved knows what it actually evidenced.
The enterprise challenge: governance as paperwork
Access governance asks three questions continuously: who has access to what, should they, and can we prove the answer? Manual processes fail all three. Entitlement data scattered across systems means "who has what" requires an extraction project before every review. "Should they" is unanswerable when entitlements are raw group names with no connection to job function. And proof consists of emailed spreadsheets - the weakest evidence an auditor will accept, and increasingly one they will not.
Segregation of duties adds a harder problem: some access combinations are dangerous even when each grant is individually reasonable. The person who can create a vendor should not also approve payments to one. Detecting such toxic combinations across systems, by hand, is effectively impossible - which is why SoD violations are typically discovered by auditors, or by incidents.
Why review campaigns alone cannot fix this
Running the same broken review more often does not help; the defect is the input. Reviewers rubber-stamp because they are asked to judge entitlements without context - no role linkage, no request history, no indication of what changed since last time. Governance improves when access has structure: when entitlements roll up to roles that mean something, when every grant traces to a request and an approval, and when the review presents deltas and exceptions instead of the entire universe.
The Tanflow approach: structure first, then certify
The Tanflow IAM Suite's RBAC and Governance capability provides that structure - roles, access requests, certification and segregation of duties in one module, on top of the platform's single identity directory.
- Roles: entitlements are organised into roles aligned to job function, so both provisioning and review operate on units a human can evaluate. Where attributes should drive access directly, dynamic policies recalculate entitlements as facts about the user change.
- Access requests: access beyond the role baseline is requested through the platform and approved with a recorded decision - so every exceptional grant carries its own justification from birth.
- Certification: review campaigns run inside the platform against live entitlement data, and a reviewer's revoke decision feeds back into enforcement rather than into a spreadsheet someone must action later.
- Segregation of duties: conflicting-access rules are defined once and evaluated by the platform, surfacing toxic combinations instead of waiting for the auditor to sample into one.
The governance workflow in practice
- Joiners receive role-based birthright access automatically; anything further is requested and approved on record.
- SoD rules screen requests and existing assignments for conflicts.
- Certification campaigns present reviewers with structured, contextual entitlement sets; decisions execute directly - revoked means revoked.
- Every grant, request, approval, conflict and certification decision lands in the audit trail, searchable and exportable.
Enterprise scenario
Consider a banking organisation preparing for a regulatory inspection of user access management. Historically this meant weeks assembling entitlement extracts and chasing sign-offs. With governance running on the platform, the inspection artefacts already exist: current role definitions, the request-and-approval record behind every exception, the last campaign's decisions with timestamps, and the SoD rule set with its violation history. The preparation project becomes an export.
Security and audit implications
Structured governance changes both risk and evidence. Risk falls because entitlement creep is caught by design - movers' access recalculates with their role, exceptions expire into the next review with their justifications attached, and toxic combinations are blocked at request time. Evidence improves because the system of record for access decisions is the system that enforces them. Access certification and least-privilege expectations recur across the frameworks Tanflow maps its controls to - ISO 27001, the RBI Cyber Security Framework and others - and a platform-run certification is the form of evidence those reviews are designed to accept.
Conclusion
Access reviews fail when they ask humans to certify chaos. The Tanflow IAM Suite replaces the chaos with structure - roles that mean something, requests that carry reasons, campaigns that enforce their outcomes, and SoD rules that watch continuously - so certification becomes what it was always supposed to be: a genuine control, with evidence to match.
