About mainsec UG (haftungsbeschränkt)

It serves small and medium-sized enterprises across Germany, offering advice both digitally and on site. The company helps managing directors make informed decisions about IT security by creating clear structures, responsibilities and priorities.

Its services cover a CyberRisikoCheck for small firms, a mainsec Basisprüfung for those with ten or more staff, NIS2 and Cyber Resilience Act consulting, ISO 27001 certification support, an external information security officer role, and awareness and leadership training.
