Secure Behaviors

Arsen is a French cybersecurity startup, dedicated to enhancing human behaviors in cybersecurity.

Arsen Mission

Protect Against Social Engineering

In order to better protect against cyber threats, employees too must combat hackers.

Unfortunately, the awareness techniques deployed today are not enough.

On one hand, theoretical knowledge does not translate into practice when the employee is manipulated. On the other hand, threats continually evolve, and one cannot rely on occasional awareness operations.

This is Arsen's vision: to offer solutions that allow for continuous, effective, and concrete training of employees in order to increase business resilience against attacks targeting their staff.
