We are proud to announce the successful completion of Persy STINGER CORE — a private cloud system designed specifically for the needs of small and medium-sized enterprises.

STINGER CORE is the first all-in-one ICT solution on the Bulgarian market that combines enterprise-grade hardware, 100% open source software, and engineering support from a single provider — all within one 16U rack cabinet. The system is ready to operate from the moment it is powered on, with no installation required and no licensing fees.

Developed Under a European-Funded Project

The development of STINGER CORE was carried out under project BG16RFPR001-1.001-0368, part of the Competitiveness and Innovation in Enterprises Programme 2021–2027, co-funded by the European Union. The European funding enabled us to invest in building a product that addresses a real market gap — an affordable, secure, and fully integrated IT infrastructure for Bulgarian SMEs.

What STINGER CORE Delivers

In a single 16U cabinet with a footprint of just 0.36 m², the system combines a 3-node compute cluster with a total of 192 GB RAM, NAS storage with capacity up to 48 TB, a 10G backbone network infrastructure, an online 2 kVA UPS, and a full open source software stack — including virtualization, backup, a next-generation firewall, multi-factor authentication, and the option for local AI.

Security is built into the architecture from the ground up — it is not an add-on module. STINGER CORE technically covers all 10 measures of Article 21(2) of the NIS 2 Directive, making it a ready-made solution for organizations with regulatory compliance requirements.

Who It Is Built For

We designed STINGER CORE for SMEs with 10–150 employees that need enterprise-grade IT infrastructure but have no in-house IT team, want to avoid dependence on public cloud services, and handle confidential or regulated data — law firms, accounting offices, medical practices, manufacturing companies, financial services providers, software companies, and many others.
