This is Nessus

Passionate for over 20 years.

Your independent Internet Service Provider from Vienna.

NESSUS GmbH was founded in 1999 as a sole proprietorship by Florian Schicker, who is now the managing partner. Over the years, NESSUS evolved from a web hosting provider into a server housing and internet business ISP for organizations of all sizes.

Today, Nessus counts companies like ACP, MJAM, A-Trust, easyname, and Greenpeace among its long-standing customers.

“As an alternative provider from Austria, we have always been able to impress against the big players with tailor-made solutions and high-quality service.”
