TL;DR: Unosecur says identity attacks in 2026 increasingly succeed through valid credentials, trusted sessions, and malware-free paths, so five-minute MTTD is becoming the practical benchmark for interrupting privilege escalation and lateral movement before attackers progress further. The assumption that post-authentication activity stays reviewable long enough for conventional SOC cycles is collapsing.
Editorial analysis by NHI Mgmt Group, based on content published by Unosecur: “Identity threat detection in 2026: Why 5-minute MTTD is now the benchmark”.
By the numbers:
- 82% of detections in 2025 were malware-free, according to CrowdStrike's 2026 Global Threat Report cited by Unosecur.
Key questions
Q: What breaks when identity teams rely on static login thresholds?
A: Static thresholds are easy for attackers to work around and often too rigid for legitimate users.
Q: When should organisations treat five-minute MTTD as a security target instead of a reporting metric?
A: They should treat it as a target when attackers can move through trusted identity paths faster than analysts can correlate logs.
Q: What are the signs that identity threat detection is too slow?
A: Common signs include alerts that arrive after privilege changes have already occurred, separate tools holding authentication and entitlement data, and analysts needing to stitch together the incident manually.
Practitioner guidance
- Prioritise post-authentication behaviour analytics Correlate session activity, privilege changes, and resource access so that a valid login is only one signal in the detection chain.
- Set a five-minute containment objective Define an operational target for identity abuse that links detection to containment, including session revocation, token invalidation, and privilege rollback.
- Unify identity telemetry across SaaS and cloud Bring identity provider events, entitlement changes, and application activity into one investigation workflow so analysts do not reconstruct the attack manually.
Bottom line: Identity attacks increasingly succeed through trusted credentials and sessions, which makes post-authentication behaviour the decisive detection surface.

Five-minute MTTD is now an identity governance threshold, not a SOC preference. Once attackers operate through valid sessions and trusted credentials, the governing question becomes how quickly the organisation can recognise misuse while the identity is still active. That shifts identity security from alert production to interruption speed, and it exposes programmes that still treat authentication as the end of the control path.
A few things that frame the scale:
- 43% of security professionals are concerned about AI systems learning and reproducing sensitive information patterns from codebases, according to the State of Secrets in AppSec.
A question worth separating out:
Q: How should SOC and IAM teams split responsibility for identity threat response?
A: SOC teams should own detection, triage, and containment decisions, while IAM teams should provide the identity context and control paths that make those actions possible. The two functions need shared telemetry and approved response actions. If they are separated, the organisation loses time at the exact point when identity abuse is moving fastest.
