Who we are

Cesanta Software Ltd. is headquartered in Dublin, Republic of Ireland.

Our story roots back to 2004, when Sergey Lyubka, our CTO and Co-Founder, started Mongoose Web Server Library development.
As Mongoose Web Server grew in popularity and matured over the following years, in 2013 Cesanta was established to continue its development and provide support to our valued customers.

We are proud to have among our customers many Fortune 500 companies as well as medium and small size businesses. Security and quality of our solutions is a paramount for us and the fact that Mongoose Web Server is used by NASA aboard the International Space Station is the best confirmation to it.
