Arsen

Arsen is a French cybersecurity company founded in 2021 that specializes in security awareness training and social engineering simulations. The company uses AI to deliver phishing simulations, vishing simulations, and micro-learning training modules aimed at reducing human risk within organizations. Arsen's platform combines realistic attack simulations with behavioral training. Employees are exposed to simulated phishing campaigns and voice-based social engineering (vishing) scenarios designed to reflect current threat tactics. When employees interact with simulated attacks, they receive contextual micro-learning content to reinforce correct behaviors. The platform also generates performance reports and security scoring to help organizations measure the effectiveness of their awareness programs. The company's approach is rooted in continuous, behavior-focused training rather than periodic theoretical instruction. Arsen targets the human element of cybersecurity, operating on the premise that employees represent the last line of defense against social engineering attacks. Their training scenarios can be contextualized to specific situations, such as remote work environments, to reflect realistic threat conditions employees may encounter. Arsen serves over 400 clients and has trained more than 500,000 employees. The company raised €2.5 million in seed funding from investors including Elaia, French Founders, and BPI France. It has received coverage from outlets including HackRead and L'Usine Digitale. The platform is targeted at businesses seeking to reduce their exposure to phishing, vishing, and other social engineering threats by improving employee security behavior.
