Access controls are necessary. They are not sufficient.
MFA, PAM, and IGA reduce the attack surface significantly. But attackers are adaptive — they steal credentials, abuse legitimate access, move laterally using valid accounts, and exploit the gap between what controls allow and what is actually normal. Those behaviours leave signals. ITDR is the discipline of finding them.
Nomios delivers ITDR as a bridge between the Identity Security and Detection & Response domains — combining deep identity expertise with SOC operational capability to detect, investigate, and respond to identity-based threats in real time.
The gaps that ITDR fills
Access controls define what is allowed. ITDR detects when allowed access is being abused — often by attackers using legitimate credentials that no access control would block.
Credential theft is invisible to IAM
- A stolen credential authenticates successfully. IAM sees a valid login — ITDR sees an impossible travel event, an unfamiliar device, or an anomalous access pattern that signals compromise.
Lateral movement uses valid accounts
- Attackers move through environments using legitimate accounts and protocols. PAM controls privileged access — ITDR detects the abnormal patterns of use that indicate an attacker is behind the keyboard.
Privilege escalation happens within policy
- Many escalation paths exploit misconfigurations or legitimate features — Kerberoasting, DCSync, token manipulation. They do not trigger access controls. They trigger ITDR.
Identity-based attack techniques
The most common and damaging identity threats — each requiring detection capability that goes beyond access controls.
- Detecting the use of stolen or compromised credentials — through impossible travel, unfamiliar locations, anomalous login times, and deviation from established user behaviour baselines.
- Identifying attacker movement through the environment using valid credentials — including pass-the-hash, pass-the-ticket, and abnormal authentication patterns across systems and domains.
- Detection of Kerberoasting, DCSync, golden ticket attacks, and other Active Directory exploitation techniques that target privileged access through the identity layer rather than the access control layer.
- Detecting adversary-in-the-middle attacks, token theft, and MFA fatigue techniques that allow attackers to bypass multi-factor authentication and hijack authenticated sessions.
- Identifying anomalous access patterns, unusual data access, and behavioural deviations that indicate an insider threat — whether malicious, negligent, or compromised.
- Detecting abuse of cloud identities, service principals, and OAuth applications — including consent phishing, token theft, and cloud-native privilege escalation paths that on-premise tools miss entirely.

Three ways to engage
ITDR spans identity expertise and SOC operations. Our service lines reflect both dimensions.
Professional services
ITDR platform deployment and integration — connecting identity sources, tuning detection rules, and building the response playbooks that make detection actionable.
Managed services
Continuous monitoring of your identity environment by our SOC team — with 24/7 detection, analyst-led investigation, and rapid response to identity-based threats.
Consulting services
ITDR strategy, use case design, and integration architecture. We help you understand your identity threat exposure and design a detection programme that addresses it.
Identity expertise meets SOC capability
Identity and detection under one roof
- Most SOCs understand endpoints and networks. Nomios combines deep identity expertise with SOC operational capability — giving you analysts who understand both what is happening and what it means in an identity context.
Connected to IAM and PAM
- ITDR is most effective when it is informed by your IAM and PAM controls. Our identity practice means we understand your access landscape — and can build detection that reflects it accurately.
On-premise and cloud covered
- We detect identity threats across Active Directory, Entra ID, Okta, and cloud-native identity services — covering the full hybrid identity landscape that most organisations operate.
Response that goes beyond alerting
- Detection without response is just notification. Our managed ITDR service includes real containment actions — disabling accounts, revoking sessions, blocking lateral movement — executed in real time.
Are identity-based attacks visible in your environment?
For most organisations, the honest answer is no. Talk to our team about what ITDR coverage would look like for your identity landscape.
