Two decades of technology. Built for what’s next.
Signet CS was founded in 2005 with a clear mission — to be the technology partner that businesses in Serbia can rely on. Over 20 years, we have grown from a small IT company into a full-service technology provider, covering everything from cloud and cybersecurity to infrastructure, hosting, networks, and consulting.
Who we are
Signet CS is an IT company founded in 2005 and headquartered in Belgrade. We provide end-to-end IT services to small and medium businesses across Serbia — we design, deliver, and maintain the systems your business runs on.
We work with major global vendors and key local distributors to deliver reliable, long-lasting solutions. When a project requires additional expertise, we engage trusted external specialists — so the right skills are always available.
Our mission
Our mission is to make enterprise-level technology accessible to businesses of every size. We believe that great IT should not be a privilege of large corporations — every business deserves a reliable technology foundation and a partner who understands their needs.
We achieve this by combining technical expertise with a genuine commitment to our clients’ success. When your business grows, we grow with you. When something goes wrong, we are there to fix it — quickly and professionally.

Leadership
Mihailo Stefanović
Founder & CEO
With over three decades of professional experience in IT, Mihailo Stefanović founded Signet CS in 2005 after years of working as a contractor for local and international companies. His expertise spans web development, network and system administration, computer hardware and software, cloud infrastructure, and electronic publishing.
Mihailo holds professional certifications from SonicWall, Fortinet, VMware, Sophos, and a number of other vendors, and has led Signet CS to become a certified partner of Microsoft, Google, HP, HPE, and many others across the industry. Since 2007, he has also served as IT Director of Projekat Rastko, an international cultural network.
His philosophy is straightforward: technology should serve people, not the other way around. That belief has shaped Signet CS from day one.
