Fox-IT
Fox-IT is an IT and cyber security company with a strong portfolio of security and intelligence products, founded in 1999 by Ronald Prins and Menno van der Marel, and incorporated in the Netherlands. The company is trusted by governments, agencies and major organizations world­wide, has a presence in many countries and employs over 150 people (2012). Since 2015, Fox-IT is part of NCC Group. In 2024, Fox Crypto was branched out and is now known as Sentyron.


Fox-IT started in 1999 as the first digital investigation company in Europe. It was founded by Ronald Prins and Menno van der Marel, who both had a background in Digital Forensic In­ves­ti­ga­tions and in hacking security systems, at the Netherlands Foresensic Institute (NFI). Apart from conducting digital forensic investigations and security audits, Fox-IT has developed a series of products for the protection of state secrets. In 2003, the company bought part of the legacy of Philips Crypto in order to get access to technology for the protection of state secrets, such as the GCD and GCD-Φ crypto chips and the V-Kaart Project (which later became FFFE).

In 2011, Fox-IT was in the news worldwide for investigating the security breach at the Dutch Certification Authority (CA) Diginotar, which appeared to be caused by Iranian hackers. In 2015, Fox-IT became part of the NCC Group (UK). Fox-Crypto — established in 2003 and responsible for the company's crypto­graphic products — was sold on 1 August 2024 to CR Group Nordic AB, and was renamed Sentyron the following year (2025).
