We are Stemil.

We started in 2004 as Magenta Net, providing internet access in Sofia. Over the years we realised that businesses needed something more – a dependable partner to look after their infrastructure and protect their data.

From 2008 we turned fully to supporting networks and servers, and gradually added cyber security. That same year we became Stemil BG. Since then we have helped companies work with peace of mind – without needless outages and without hidden risks.

We have more than 20 years of experience. Our clients include state and municipal bodies, schools and universities, insurers, pension funds, manufacturers and trading companies, IT and pharmaceutical firms. Different businesses, the same needs – stable infrastructure and protected data that work for them around the clock.

We have been certified to ISO 9001 and ISO 27001 since 2011 and pass external audits every year. Our team trains and certifies regularly with Microsoft, Cisco, Fortinet and other leading vendors. This is not just paperwork – it is how we make sure the solutions we offer are current and actually work.

We work to clear service level agreements (SLAs) and through a dedicated ticketing system. You know what to expect. You know how quickly we respond. And you know the priorities have been agreed in advance.

Our focus is on three things:

• monitoring and support of network and server infrastructure
• cyber security
• cloud services

We help businesses not only to put solutions in place but to run them so that they meet the requirements of ISO 27001, ISO 22301, NIST and other standards. Our aim is simple – your business runs without unpleasant surprises, and your data stays protected.

If you are looking for a partner who understands both the technology and the real needs of the people behind it – you are in the right place.
