What Mastertel does

Mastertel (АО «Мастертел», Joint-Stock Company Mastertel) is a privately held Russian B2B IT infrastructure provider headquartered in Krasnogorsk, Moscow Oblast, operating since 2000 (brand registered 2002). The company owns and operates the MasterConnect fiber network — a 12,000+ km radial-ring backbone with full backbone redundancy covering more than 80% of commercial buildings across Moscow and the Moscow region, with average customer connection distance under 350 meters. Mastertel serves over 10,000 Russian and foreign companies, including major banks (Sberbank, VTB, Gazprombank, Raiffeisen Bank, Uralsib, Bank Otkritie), telecoms (Rostelecom, Megafon), government (MChS), and technology firms (Yandex, Mail.ru, Kaspersky Lab, Huawei, Aeroflot). Approximately 150 telecom operators use Mastertel's network as their underlying infrastructure, and 20+ Tier-3 data centers are accessed via the 3data partnership.

The product portfolio is organized around three pillars. Connectivity: dark fiber rental and sale, leased channels up to 100 Gbps (DWDM 1G/10G/40G/100G), high-speed business internet, and independent route redundancy. Cloud and security under the MasterCloud sub-brand: IaaS, SaaS, BaaS, DRaaS, VPS+, VDI+GPU, FortiDDoS protection, Perimeter honeypot/IDS, and IB outsourcing using SearchInform KIB DLP, built on HPE and IBM infrastructure with Cisco networking. Telephony and services: virtual PBX, IP and fixed-line telephony, multi-channel Moscow 495/499 and 8800 numbers, colocation, and turnkey fiber network design and construction including trade-in of legacy cables. ISO/IEC 27001:2022 ISMS certification (TÜV AUSTRIA, 2025) and full Minkomsvyaz/Roskomnadzor telecom licensing underpin the regulated enterprise and government workloads.

The business model is overwhelmingly recurring subscription-based (annual billing on enterprise connectivity and cloud contracts, monthly per-seat and usage-based billing on cloud services), with one-time fiber purchase options and professional services revenue from network construction. GTM is dual: a direct enterprise sales force targets large corporates, banks, and government, while a channel motion leverages 150+ telecom operators and Tier-3 data center operators (3data, IXcellerate, DataPro) to reach mid-market and SMB customers. Pricing is quote-based and customized, with multi-year discounts and partner leasing programs (up to 100% fiber discount when bundled with communications and cloud).
