In April 2026, one phishing email opened the door to the police servers in Ardmore, Oklahoma. Attackers encrypted six months of criminal complaints and active investigations, then demanded $300,000 to keep it all off the internet.

The city’s network was segmented by department, so billing and 911 stayed up. But inside the police environment, nothing stood between the attacker and the records they sought.

Ardmore is a reminder that an agency doesn’t have to be big to be worth attacking.

Criminal justice information services (CJIS) teams hold key data and run vital public services. Attackers may steal funds or data. They may spread false claims or shut down key work. A breach can slow a case, halt work, and harm public trust.

Federal rules call for a Zero Trust plan. Teams must validate each request, limit traffic to only what’s required, and plan for a breach.

Illumio helps CJIS teams put this plan to work. Illumio helps you see how apps and systems connect in real time and then segment traffic between them. Breaches are inevitable, but with Illumio, they have fewer ways to spread.
