TL;DR: Identity attacks now bypass many EDR assumptions because valid credentials and trusted SaaS sessions can carry the intrusion, according to Blackpoint Cyber. MSP environments need faster account suspension, session termination, and tighter delegated access to limit how far authenticated abuse spreads.
Editorial analysis by NHI Mgmt Group, based on content published by Blackpoint Cyber: “Identity Is the New Perimeter: Why MSPs Can No Longer Rely on EDR Alone”.
By the numbers:
- High-confidence identity attacks can be contained in as little as 21 seconds.
Key questions
Q: Why do stolen credentials make lateral movement easier in enterprise environments?
A: Stolen credentials preserve the trust relationships already mapped into the environment.
Q: How can security teams know whether identity controls are actually reducing breach impact?
A: Look for evidence that suspicious accounts are contained fast, active sessions are terminated, and privileged access is limited to the smallest possible set of systems.
Q: What breaks when EDR is the main defense against identity-based attacks?
A: EDR breaks down when the attacker does not need malware at all.
Practitioner guidance
- Harden technician and support identities Restrict MSP technician accounts to the minimum delegated access needed for each client, and separate administrative scopes by environment so a single compromise cannot traverse every tenant.
- Instrument identity-layer detection Collect cloud identity, SaaS, and session telemetry alongside endpoint events so suspicious logins, token misuse, and mailbox-rule changes can be correlated in one response path.
- Reduce response time to identity compromise Automate containment steps for high-confidence identity abuse, including account suspension, active session termination, and forced password reset, before the attacker completes lateral movement.
Bottom line: Identity attacks now bypass many EDR assumptions because the attacker can operate through valid credentials and trusted SaaS sessions.

Identity telemetry, not endpoint telemetry, is becoming the primary security signal for MSPs: EDR still matters, but it no longer defines the earliest point of control when attackers authenticate with valid credentials. Identity is now where abuse begins, which means access patterns, session anomalies, and privilege scope deserve the same operational attention as host events. Practitioners should treat identity logs as first-class detection data, not supporting evidence.
A few things that frame the scale:
- Only 5.7% of organisations have full visibility into their service accounts, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: What should MSPs do when a client identity is compromised?
A: MSPs should contain the account immediately by revoking the session, suspending the identity, and forcing a credential reset before the attacker can expand access. The key test is whether the response path is fast enough to matter while the compromised login is still active.
