Ransomware doesn't need to be sophisticated if it's allowed to execute. A growing number of security teams are shifting focus from detecting ransomware to preventing execution in the first place — controlling applications, scripts, and installers so unauthorized code never gets the chance to run.

Many security strategies still assume everything is allowed until proven malicious. Attackers understand that model well. That's why more organizations are rethinking endpoint security — shifting from detection-first tools to control-first approaches that reduce attack surface before an incident occurs.

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. Fewer unknowns means fewer opportunities for attackers. Learn more at ThreatLocker.com

Security controls fail when they break the business. Successful teams phase in protections gradually — starting with visibility, then moving to enforcement. That approach allows organizations to reduce risk without overwhelming IT teams or disrupting critical workflows. Learn more at ThreatLocker.com

Detection-based security assumes you'll catch an attack in time. Control-based security assumes you won't. That mindset shift is driving more organizations to focus on preventative controls — stopping unknown execution and unauthorized privilege elevation instead of relying solely on alerts after the fact.

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
