Meet the team

You've seen the brands. Now meet the people.

Most security companies were built to detect and walk away. We built a group the other way around — specialist brands that take a threat from found to fixed, for organisations that don't have a security team to lean on.

The exec team

Proven operators. Backing it themselves.

Our founding team has started, scaled and sold real companies. We know what it's like to run a business with no time to spare and no room for a breach — and that shapes every brand in the group.

Most tools bolt AI on at the end. Ricardo has built detection around it for years.

Before most of the industry was talking about AI in security, Ricardo was building it into the core of real detection systems — architecting AI-powered SIEM platforms that correlate millions of signals in real time for organisations in some of the most regulated industries there are.

Plenty of tools can collect data. Far fewer can make sense of it fast enough to act. Ricardo has spent his career solving that problem at scale, mapping detection to the frameworks businesses are judged against: SOC 2, ISO 27001, HIPAA and PCI.

Across the group, he helps shape the intelligence layer — how our platforms ingest, correlate and prioritise what they find. His standard comes from running real operations: if it wouldn't hold up defending a regulated business at 3am, it isn't good enough.
