TL;DR: Active Directory identity attacks can chain misconfigurations into full domain compromise in minutes, and the article argues that passive monitoring alone leaves defenders blind to the earliest abuse signals, according to Horizons.ai. The real issue is that identity telemetry often arrives after the attacker has already converted credential misuse into lateral movement and privilege escalation.
NHIMG editorial — based on content published by Horizons.ai: What is ITDR and Why Active Directory (AD) Tripwires Make It Real
By the numbers:
- The benchmark showed full domain compromise in just 14 minutes, without CVEs, poisoning, or insider knowledge.
- 40% of Active Directory attacks result in successful, successful compromise.
Questions worth separating out
Q: How should teams reduce the attack surface of Active Directory identities?
A: Start by removing standing privilege, then shorten the lifetime of every elevated grant.
Q: Why do Active Directory attacks often evade SIEM and EDR?
A: Because many identity attacks blend into normal directory traffic.
Q: What breaks when identity monitoring is only passive?
A: The defender loses the ability to prove that an event is malicious before the attacker has already escalated.
Practitioner guidance
- Test identity detections against real attack paths Run controlled AD abuse scenarios that include credential attacks, privilege escalation, and lateral movement so you can measure whether alerts trigger before compromise expands.
- Deploy decoy identities in high-risk directory zones Place believable but unusable accounts where attackers are likely to enumerate, then treat any interaction as a priority signal for triage and containment.
- Measure detection quality by time-to-trustworthy-alert Track how long it takes from first malicious directory touch to a high-confidence alert that an analyst can act on.
What's in the full article
Horizons.ai's full blog post covers the operational detail this analysis intentionally leaves for the source:
- How NodeZero Active Directory Tripwires are positioned to surface suspicious identity interactions in live environments.
- The specific identity attack patterns the vendor associates with decoy accounts, including Kerberoasting and AS-REP roasting.
- The customer example showing weak passwords, misconfigured accounts, and lateral movement into production.
- The practical demonstration angle for teams evaluating ITDR workflows in their own environments.

Passive identity monitoring is not a control, it is an observation layer. When attackers can use Kerberoasting, AS-REP roasting, token replay, and overprivileged accounts without tripping a trustworthy alert, the environment is not detecting identity abuse early enough to matter. The implication for practitioners is that ITDR must be judged by signal fidelity, not dashboard volume.
A few things that frame the scale:
- 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, according to Ultimate Guide to NHIs.
- Only 5.7% of organisations have full visibility into their service accounts, which is why detection programmes so often start from an incomplete baseline.
A question worth separating out:
Q: Who is accountable when Active Directory privilege escalation is possible?
A: Accountability sits with the organisation operating the directory, because effective permissions reflect local governance decisions. Frameworks such as NIST CSF and zero trust expect access to be understood and controlled, not assumed safe because it is documented somewhere.
