How can organisations reduce risky SaaS permissions without slowing the business?

Why This Matters for Security Teams

Reducing risky SaaS permissions is not a cleanup exercise, it is a control problem that affects speed, incident exposure, and audit readiness at the same time. Excess access tends to accumulate in SaaS apps because ownership is scattered across business teams, approvals are inconsistent, and revocation is often treated as a separate ticket. NHI Management Group’s Ultimate Guide to NHIs — Key Challenges and Risks notes that 97% of NHIs carry excessive privileges, which is exactly the pattern that makes SaaS environments hard to govern at scale.

The practical risk is not just overpermissioned users or service accounts, but the business delay created when detection, approval, and revocation live in separate workflows. That delay keeps unnecessary access active longer than it should be, and it forces security teams to choose between blocking work or tolerating exposure. Current guidance from the OWASP Non-Human Identity Top 10 aligns with this: visibility without action is not enough. In practice, many security teams encounter risky SaaS access only after a misuse event or audit finding, rather than through intentional governance.

How It Works in Practice

The fastest way to reduce risky permissions without slowing the business is to make remediation workflow-driven instead of review-driven. That means the team that finds a dangerous entitlement can immediately route it to the correct owner, obtain a business decision, and remove or scope down the access in the same process. The goal is not blanket denial. It is faster, higher-confidence governance tied to who owns the application, the data, and the permission.

A workable pattern usually includes three pieces. First, classify SaaS permissions by risk so teams can focus on the accesses most likely to cause damage, such as admin roles, OAuth app scopes, delegated inbox access, and service integrations. Second, connect discovery to ownership so there is a clear approver for each app or identity. Third, use pre-approved playbooks for common actions like revoke, downgrade, re-consent, or force reauthentication. This is consistent with the risk-prioritised remediation approach described in NHI research and with the control intent behind the NIST Cybersecurity Framework 2.0, which emphasizes identify, protect, detect, and respond as linked functions rather than separate silos.

For SaaS specifically, organisations should also watch for permissions that are technically valid but operationally unnecessary. Examples include stale app grants, orphaned admin roles, broad third-party integrations, and long-lived tokens that survive employee movement or project change. NHI Management Group’s Top 10 NHI Issues is useful here because it highlights how overprivilege and weak revocation practices turn routine access into recurring exposure.

• Use one queue for discovery, approval, and revocation so remediation does not stall.
• Route decisions to the true business owner, not a generic security mailbox.
• Prioritise high-impact SaaS permissions first, especially admin and third-party app access.
• Replace manual exceptions with repeatable playbooks for common risk cases.

These controls tend to break down when SaaS ownership is unclear across subsidiaries, contractors, and shadow IT because the approval path becomes ambiguous and revocation authority is contested.

Common Variations and Edge Cases

Tighter permission control often increases coordination overhead, so organisations have to balance fast remediation against business continuity. The best practice is evolving rather than universal, especially in SaaS estates where the same permission can be low risk in one app and high risk in another.

One common edge case is shared integrations owned by IT but used by multiple business units. In those environments, a simple revoke can disrupt workflows, so current guidance suggests scoping down access first, then replacing broad grants with narrower permissions or separate service identities. Another edge case is third-party app consent, where the risky object is not a user role but a consented integration with persistent token access. That is where governance should focus on consent review, token expiry, and rapid re-consent workflows rather than manual entitlement spreadsheets.

Vendor research from The 2024 ESG Report: Managing Non-Human Identities shows how widespread identity risk already is across organisations, which is why slow exception handling becomes a security issue quickly. For implementation teams, the important test is simple: can a risky SaaS grant be detected, approved, and removed in one operational path without waiting for a monthly review cycle? If not, the process still protects the business on paper more than in practice.
