2lrn4
A security awareness platform with more than sixty courses in twenty-seven languages, so a policy written in one country can actually be taught in all the others.
C3BR Holding bv is the holding company behind Cyber Inc bv, which builds and operates three platforms — 2lrn4, Kantyra and Crumm — and delivers the services around them, from CISO as a service to NIS2 and ISO 27001 work. We don't sell a position. We put knowledge of information security and of running a company to work for organisations that need both.

A security awareness platform with more than sixty courses in twenty-seven languages, so a policy written in one country can actually be taught in all the others.
An ISMS and GRC platform for getting in control and staying there: the standards, laws and rules an organisation is held to, with the evidence that it meets them.
A CRM for small and starting companies — the ones growing a business with no sales department yet. Built on the same conviction: good administration is what lets a company scale.
Platforms handle the record-keeping. Deciding what matters, arguing it out with a board and carrying the responsibility afterwards is still a job for a person. That is the service half of the company.

“C3BR doesn't position itself. We help organisations with our knowledge and expertise in information security and in entrepreneurship.”
