TL;DR: Lateral movement lets an attacker start with one foothold and then use credentials, remote admin tools, and overlooked trust paths to reach sensitive systems, according to StrongDM. The security problem is not just detection speed but the identity and privilege relationships that make movement look legitimate until it is too late.
Editorial analysis by NHI Mgmt Group, based on content published by StrongDM: “What Is Lateral Movement? (And How to Detect & Prevent It)”.
By the numbers:
- The average breakout time fell by 67% over the past year, and more than one-third of adversaries broke out in less than 30 minutes.
- StrongDM reports that 97% of the behaviors executed did not have a corresponding alert generated in the SIEM.
Key questions
Q: What breaks when an attacker can move laterally with valid credentials?
A: The failure is that internal authentication no longer proves legitimacy.
Q: Why do valid credentials make lateral movement so hard to detect?
A: Valid credentials let attackers appear to be normal users or administrators, so the traffic often blends into routine operations.
Q: What are the signs that lateral movement controls are not working well enough?
A: Weak lateral movement controls usually show up as unusual authentication patterns, unexpected process creation, and network traffic between systems that rarely communicate.
Practitioner guidance
- Map lateral movement paths Inventory which users, service accounts, and admin tools can move from low-value systems to high-value assets.
- Separate user and admin accounts Remove the habit of letting one identity span ordinary work and privileged administration.
- Enforce least privilege on internal reachability Review who can authenticate to sensitive systems and cut back broad internal access that allows a foothold to become a bridge.
Bottom line: Lateral movement turns one compromised foothold into a broader identity and access problem, because the attacker uses valid credentials and trust paths to move legitimately inside the environment.

Lateral movement is an identity governance failure, not just a detection problem: the attack succeeds because the organisation has already allowed credentials and admin relationships to span too many systems. Once valid access exists across multiple tiers, the attacker no longer needs to behave like an intruder to keep moving. Practitioners should treat internal reachability as a governed identity property, not an incidental network condition.
A few things that frame the scale:
- 82% of detections were malware-free, with attackers using valid credentials and trusted tools, according to CrowdStrike's 2026 Global Threat Report.
A question worth separating out:
Q: How do IAM and PAM teams reduce lateral movement through machine identities?
A: Start by eliminating standing access paths that let one machine identity reach many sensitive systems. Then bind privileged access to purpose, context, and shortest-possible duration, with logs that show which identity used which privilege and why. That combination reduces reuse, constrains blast radius, and improves incident investigation.
