About us

m-privacy GmbH

Located in Berlin, m-privacy GmbH develops innovative client-server solutions for the secure Internet connection of computer workstations based on TightGate technology.
In addition, we provide a comprehensive service portfolio for IT security and corporate privacy for professional users.


IT security

Secure Internet connection of computer workstations in government agencies, public administration institutions and industrial companies by means of Remote-Controlled Browser Systems (ReCoBS) is our core business. These systems are upstream of internal networks and effectively prevent attacks and unwanted data leakage due to security gaps in locally installed web browsers through their separating effect.
The highly hardened server systems developed by us allow Internet use at the workplace even in vulnerable, respectively critical environments. The main product TightGate-Pro has been successfully certified according to the protection profile (PP) 0040 "ReCoBS" of the German Federal Office for Information Security (BSI).

Privacy & ISO 27001

In many cases, legal requirements force professional users to take comprehensive measures to comply with legal privacy regulations. The range of services offered by m-privacy GmbH goes beyond mere consulting on privacy aspects:

We perform fundamental analyses of operational situations, train employees regarding privacy-compliant procedures and improve internal processes in the long term. Last but not least, we provide external data protection officers as an alternative to internal staff.
