Sometimes it's just good when nothing happens.
We use Microsoft's Exchange Server and were not affected by the current security vulnerability because it was closed in time by Sentinel-It.

The introduction of Microsoft Teams into our work processes and the changeover to cloud-based work
has been extremely helpful for us in the Corona year. Sentinel IT was and is a permissible service provider for us, and we are happy to recommend them to others.

The guys from Sentinel have modernized our network so much that we can now work absolutely paperless and also largely emailless. A huge step forward compared to the past.
Great praise to Mr. Heymeier and his team.
Always super accessible, competent and solution-oriented. I can recommend them to everyone.

Sentinel IT supported us so strongly during the crisis that we can absolutely recommend them.
They responded very quickly to the difficult situation and provided us with a digital concept, which enabled us to maintain our business operations as far as possible. We will continue to use this independently of the Coroan process, as it has also opened up many efficiency points.

We have been using Sentinel IT regularly for years and are very satisfied. We have also been able to benefit from many innovations and innovative suggestions during our long business relationship. Even if some of them were not implemented in the end, we are very grateful for the constant commitment and "brainstorming".

We are very satisfied with Sentinel IT, also because the distance (company headquarters is in Bremen) is not a barrier at all. Keep it up!

Absolutely innovative squad. The IT infrastructure area is highly interesting for our company and mainly eliminates problems around IT in the areas of security, hardware and failures. But it is best for my nerves. I would give 10 stars.
