Firewalls? We can do that at qwertiko!

Our colleague Jens Groh has been an active member of the pfSense® open source community for many years and is considered one of Germany’s leading experts in this field. Not only do we as colleagues benefit from his expertise—he also passes on his specialist knowledge directly to you in our training courses!

We offer both beginner courses and workshops for advanced users, always keeping up to date with the latest stable version. In addition to the fixed content, we naturally take plenty of time to answer your questions about operating your firewall software.

The better you understand your firewall solution, the more efficiently you can work with pfSense® or pfSense® Plus.
