Least privilege isn't about distrusting users — it's about limiting blast radius. Many attacks succeed because malware inherits excessive permissions. Enforcing least privilege helps ensure that even if something goes wrong, attackers can't easily escalate access or move laterally across the environment. Learn more at ThreatLocker.com

Most breaches don't start with a zero-day — they start because something unexpected was allowed to run. One way organizations reduce risk is by shrinking the attack surface: deciding what software should be allowed to execute and blocking everything else by default.
