Making cyber security
more effective.

We’re an ambitious team, based in Brighton's thriving tech scene. Helping organizations around the world manage their security risks and escape the unknown.

"I founded this business knowing that the way we approach penetration testing has not kept up with the pace of change in technology. It’s been my goal to push penetration testing and vulnerability management to meet the demands of our clients in today’s digital world.”

Marios Kyriacou, CEO and Founder, Informer

Our purpose

We want a world where security unknowns are eliminated. Modern digital and SaaS businesses treat security as a 24/7 priority, not a nine to five problem. 

Yet penetration testing remains in the past, scoping projects at a glacial pace, producing clunky PDF reports, taking one-off snapshots of an ever-changing risk landscape.

We changed this. We're on your side and we’ve purpose-built Informer to advance knowledge, inform decisions and strengthen businesses like yours.

How we got here

Informer arrived in 2014, as an experimental product from leading cyber security business The Security Bureau.

It was an instant success. The unique fusion of live asset discovery, vulnerability scanning and expert penetration testing, via a single SaaS platform, appealed to businesses worldwide.

Today, Informer is at the center of cyber security decision-making for clients in many sectors and countries, with more tech-savvy businesses coming on board all the time.

We are a company of highly skilled penetration testers, developers and researchers working together to offer business-critical security information and uninterrupted peace of mind.
