What are the biggest cyber risks facing K-12 schools today and how can they keep up? Bryan Ruzenski, Director of External Technology Services at the Chester County Intermediate Unit (CCIU) shares examples from the frontlines: from students using AI to bypass filters to the hidden risks of smart HVAC systems. Legacy defenses are falling short. They can’t see into encrypted traffic or keep up with modern threats. They rely on static rules and infrequent updates, leaving months of exposure to new vulnerabilities. CCIU's vision is a private, secure cloud environment based on Zscaler’s zero trust architecture that protects every student, teacher, and staff member, wherever they connect, while freeing schools from the costs and complexity of maintaining legacy infrastructure. The aim is to empower schools with a secure, cloud-based environment where every connection is verified and every user is protected. Schools can then focus on what matters most: teaching and learning.
