Proxy Circumvention Engine that Stops Student Bypass Attempts in Their Tracks

New ContentKeeper innovation uses real-time detection, risk probability scoring, and proactive enforcement with a verified accuracy rate of 99.99% helping schools stay ahead of AI-powered proxy circumvention. 

NOTTINGHAM, UK – June 11, 2026 

Ativion today announced the launch of its dynamic ContentKeeper Circumvention Detection Engine that is designed to help schools and districts detect and stop proxy bypass attempts before they spread.

Helping Schools Address a Fast-Moving Proxy Problem

Proxy circumvention has become increasingly sophisticated, with students using formerly trusted environments, deep links, subdomains, and AI-generated sites to access inappropriate content, games, and other blocked material. Once a bypass method is discovered, it can be shared quickly among students, creating widespread proliferation before IT teams can manually respond.

Conventional blocklists and filtering solutions are struggling to keep pace. Ativion’s Circumvention Detection Engine addresses this challenge with real-time detection, heuristic analysis, and continuously evolving intelligence that identifies and blocks evasive proxy behavior as it emerges.

“Proxy circumvention has caught on like wildfire and taken schools by surprise with its sophistication,” said Jason Tomlinson, CEO at Ativion. “Students can create and share bypass sites almost instantly, and with the use of AI, they can spin up new ones faster than traditional blocklists can catalogue them. Staying ahead of proxy bypass attempts once seemed nearly impossible. ContentKeeper’s Circumvention Detection Engine changes that by detecting these threats in real time, stopping them before they spread, and helping schools maintain safe, compliant learning environments.”

The new engine analyzes URLs, site characteristics, and proxy-like behaviors using advanced scoring logic. When a potential proxy bypass site exceeds a defined risk threshold, ContentKeeper can block the site, catalogue it, and propagate that intelligence across protected environments for rapid response across devices, operating systems, and locations.

ContentKeeper’s Circumvention Detection Engine helps schools:

• Detect proxy bypass attempts in real time before they spread across the school environment.
• Move beyond traditional blocklists with sophisticated scoring and adaptive detection.
• Identify proxy circumvention patterns across sites, subdomains, and delivery methods.
• Block evasive sites proactively before students can widely access or share them.
• Support compliance efforts aligned with CIPA, KCSIE, and broader safeguarding requirements.
• Reduce false negatives through a continuously improving detection model.

The Circumvention Detection Engine is part of ContentKeeper’s broader student safety and web filtering platform. By cataloging detected proxy sites and sharing intelligence across protected environments, ContentKeeper enables schools, districts, and multi-academy trusts to respond quickly and consistently across operating systems, devices, and locations.
