The start-up that creates security with engineering science

Circle Networks is a technology company that is driven by engineering principles. Because we are convinced that this is what it takes to build sustainably secure systems.


Secury made easy since 2018

Circle Networks was founded in January 2018 with the goal to create secure, but easy-to-handle networking equipment. Companies must be able to enjoy the benefits of digital transformation without needing to worry about security or having to become experts themselves. Such is not acceptable for any other industrial product — and it should not be for information technology either.
