We believe everyone deserves a phone that only rings when it matters. CallCenturion™ is the technology making that a reality across the UK & Ireland.
Nuisance calls are more than an annoyance — they erode trust, waste time, and cause real harm to vulnerable people. In the UK alone, millions of spam and scam calls are placed every single day. We built CallCenturion™ because we believe the answer isn't a longer blocklist. It's smarter technology that can tell the difference between a real person and a robot before your phone even rings.
Our patented IsHuman Check™ is the first voice-based CAPTCHA of its kind — purpose-built to screen calls in real time, at scale, without compromising the experience for genuine callers. It's the foundation of everything we do.
From a real problem to a patented solution — here's why CallCenturion™ exists.
We saw first-hand how nuisance calls were overwhelming businesses and households. Existing solutions — blocklists, caller ID, TPS registration — weren't working. Scammers adapt. Technology hadn't kept up. We decided to build something that actually solves the problem.
After extensive research, we developed IsHuman Check™ — a voice-based CAPTCHA that operates in real time on any phone line. Unlike visual CAPTCHAs online, it works in the audio domain. Bots can't pass it. Humans don't even notice it. We filed for a patent and set about building a full platform around it.
Today, CallCenturion™ is a complete AI call screening platform — layering IsHuman Check™ with real-time AI analysis, adaptive learning, end-to-end encryption, and full call logging. It's designed to work with any UK or Irish number, with no new hardware and no disruption to how you already use your phone.
We screen calls, not people. We never record or store call content, and we never share your data with third parties. Privacy is a design principle, not a compliance checkbox.
We only succeed if our customers genuinely benefit. We measure our impact by time saved, scams blocked, and the peace of mind we give people — not just subscriber numbers.
Every screening decision is logged and visible in your dashboard. We believe you should always know exactly what happened with every call — and why.
