TL;DR: Access decisions become stale as session context changes, so continuous authorization must re-evaluate privilege throughout the session using live signals and policy, not just at login, according to Britive. The editorial case is that runtime authorization and zero standing privilege are prerequisites, because once privilege is permanent there is nothing meaningful to re-evaluate.
NHIMG editorial — based on content published by Britive: Continuous Authorization: Why One Access Decision Isn't Enough
Questions worth separating out
Q: How should security teams implement continuous authorization after login?
A: Start by treating authentication as the beginning of control, not the end.
Q: Why do long-lived sessions increase account takeover risk?
A: Long-lived sessions increase risk because they keep working after the event that should have invalidated them, such as device theft, offboarding, or credential exposure.
Q: What breaks when standing privilege is not removed for privileged users and service accounts?
A: Standing privilege breaks the assumption that access is only available when needed.
Practitioner guidance
- Map which sessions can outlive their trust conditions Identify administrative, workload, and AI-driven sessions that can remain active after device posture, risk score, or behavioural context changes.
- Pair runtime authorization with zero standing privilege Remove persistent entitlements first, then apply continuous evaluation to ephemeral access so re-checks operate on a session that can actually be narrowed or ended.
- Wire in live security signals Feed identity, endpoint, and SIEM events into policy decisions using standards such as the Shared Signals Framework and CAEP so access decisions can react while the session is still live.
What's in the full article
Britive's full article covers the operational detail this post intentionally leaves for the source:
- The step-by-step explanation of how runtime authorization and continuous authorization fit together in privileged access design.
- The standards-based signal flow behind Shared Signals Framework and CAEP integration.
- The practical response options for narrowing scope, requiring step-up approval, or ending a session outright.
- The vendor's framing of how its architecture applies continuous authorization across human, machine, and AI agent sessions.

Continuous authorization only works when access is already ephemeral. The article correctly separates runtime authorization from continuous authorization, but the deeper governance point is that continuous re-evaluation cannot rescue standing privilege. If access is permanently provisioned, there is no clean moment to revoke the underlying entitlement mid-session. Practitioners should read this as a structural boundary, not a feature gap.
A few things that frame the scale:
- The average estimated time to remediate a leaked secret is 27 days, despite 75% of organisations expressing strong confidence in their secrets management capabilities, according to The State of Secrets in AppSec.
- Organisations maintain an average of 6 distinct secrets manager instances, creating fragmentation that undermines centralised control, according to The State of Secrets in AppSec.
A question worth separating out:
Q: Who should own runtime authorization decisions in an identity programme?
A: Ownership should sit with identity, security architecture, and platform teams together, because runtime authorization touches entitlements, telemetry, application behaviour, and audit evidence. If ownership stays inside a single product team, policies become inconsistent and hard to govern. The control has to be run as a shared identity capability, not an isolated application feature.
