Offender Monitoring Software
Offmon — offender monitoring software
Monitoring to support rehabilitation, risk profiling and verification of offenders in the community.
Mission:
To support law enforcement agencies, monitoring harmful offenders whilst they live in our communities.
What Offmon does
Built for law enforcement — balanced between protection and rehabilitation.
02
AI-powered analysis on iOS and Android
Offmon analyses device activity across both platforms, identifying harmful or risky behaviour and surfacing it for an officer to act on.
03
Supports rehabilitation, protects the public
Designed not just for enforcement but to actively support offender rehabilitation, risk profiling and community verification.
How it works
Four signals, working in concert
Hash Checking
Known illegal material flagged quickly through trusted international partners.
AI Classifiers
The latest AI models detect new, harmful material that has no known hash yet.
Internet Monitoring
Web and app activity is checked against maintained lists; prohibited visits are flagged.
Keyword Logging
Risky words and phrases are scored, surfacing contextually significant activity.
The Offmon Edge
Meaningfully ahead of the status quo
First-generation detection
AI surfaces never-before-seen material that hash lists alone can't catch.
Genuine iOS and Android
Standalone, on-device iOS coverage that doesn't depend on a paired computer — alongside full Android support.
Fused real-time intelligence
Four streams combined into one actionable picture, fast enough to act on.
Why we exist
The problem is large, growing and badly served
70,000+
As of 31 March 2024, 70,052 registered sex offenders were risk-managed by police in the community — more than double the figure in 2007.

Fragmented
Monitoring practice today is inconsistent and stretched thin — not built for the scale or complexity of the current challenge.
We can do better
Modern, proportionate technology can close the gap — helping authorities monitor high-risk offenders more effectively and keep communities safe.
An independent review confirms the urgency
On the review's own projection, a sustained 6% annual rise would push the registered sex offender population managed under MAPPA towards 80,000 within two years of the review — and beyond 100,000 by 2029.
