BISDN – we whitebox networks.

Born in Berlin in 2012, we set out to bring the power of software-defined networking to the world of telecommunication. 

It took a lot of time and effort to drive this small revolution: meeting the telco industry’s high standards for reliability, precision, and predictability has always required tailored development and deep technical rigor.

Over the years, we have created the perfect blend of experienced engineers, network innovators and young talents.

Today, BISDN turns multi-vendor switches into flexible, remote OLTs and moves network management to the cloud. With our open-source mindset, we help ISPs escape vendor lock-in, scale smarter, and customize networks to their specific needs.

Envisioned by experts, built by engineers, powered by European innovation.

In 2023, we co-founded BISDN S.L. in Bilbao, Spain. The Spanish team concentrates on product development for our pOLTA product, and provide sales and support for the Spanish-speaking markets.
