Security at Trustelem

Trustelem takes a defense-in-depth approach, implementing a solid set of redundant security measures to protect client data and processes. These measures are organized in terms of infrastructure security, application security and operational security.

Infrastructure security

Trustelem's application servers are redundantly deployed in two different datacenters by an ISO 27001-certified cybersecurity hosting partner. The operation of these servers is performed by a team specializing in secure infrastructure management.

To provide multi-operator redundancy, a replicate is also deployed elsewhere in another ISO 27001-certified datacenter.

Infrastructure penetration tests are carried out at regular intervals, by highly experienced, external cybersecurity experts.

Application security

Server application

The server application is built on Go language, the leading-edge open source technology, ensuring the highest security available.

Its architecture has been defined by our cybersecurity experts and its evolution is guided by secure development methodologies. In particular, changes to the application code are documented and validated by the Trustelem Technical Director and comprehensively tested on a dedicated infrastructure before being deployed.

Application penetration tests are carried out at regular intervals, by highly experienced, external cybersecurity experts.

The application is continuously monitored to ensure the availability of services.

The application has an intrinsically defensive design:


Trustelem AD Connect application
