CybSafe is the behaviour change platform for the AI era. CybSafe points at the security behaviours most likely to cause a breach, changes them, and proves it worked – or explains why not. It's used by hundreds of enterprises to remove the guesswork in their secure behaviour and human risk management programmes. This is software built for the AI era, built on behavioural science, and powered by SebDB, the world's cybersecurity behaviour database. CybSafe is a behavioural orchestration layer for human cyber risk. Rather than doggedly focusing on any one behaviour, it points at the security behaviours that matter most to your organisation. Headquartered in London with a global customer base, CybSafe helps security teams make behavioural risk as measurable and defensible as technical risk. Change the behaviours that cause breaches. Prove it.
