Valiant Communications is an Indian designer and manufacturer that builds the secure communication and timing backbone for power grids, railways, defence forces, and other critical infrastructure - the kind of equipment that must work even when networks are under cyber-attack or satellite signals are being jammed. It started in 1994 with basic telecom multiplexers and has since evolved into a fully indigenous developer of routers, firewalls, synchronization systems, and ransomware-proof data storage, all aimed at replacing imported gear in sensitive national networks. The recurring approach is a “Make In India” competitive edge: home-grown technology, a Class 1 Local Supplier qualification, and a global customer base that trusts it to protect substations, nuclear plants, and military networks. # Business segments A single engine with five deeply interlocked product families - communication, timing, cyber defence, storage, and grid automation - all sold to the same critical-infrastructure buyers and often deployed together inside the same substation or data centre. ## 1. Communication and protection: the networking chassis everything else plugs into **The company’s routers, multiplexers, and teleprotection gear move data and protect power lines across more than 6,000 substations worldwide - this is the installed base that pulls through the rest of the portfolio.** - **The substation is the unit of scale** - Valiant’s equipment is installed in over 6,000 power substations ranging from 33 kV to 765 kV, so every new product can be sold into a site that already trusts the brand. - **Talks to old and new kit alike** - its multiplexers and cross-connects bridge legacy TDM networks and modern IP/MPLS backbones, which matters because utilities replace gear over decades, not years. - **Protection that Cisco validated** - the teleprotection line carries the signals that tell circuit breakers to trip during a fault; Cisco Systems tested it for next-generation utility wide-area networks, giving it a seal of credibility few Indian equipment makers can claim. - **Nuclear-grade reliability** - the gear has been running since 2017 inside a Swiss nuclear power plant, a reference that speaks to the extreme reliability requirements of the entire customer base. ## 2. Time and frequency synchronization: the invisible pulse that keeps grids and networks alive **If a power grid’s clocks drift by a microsecond, cascading blackouts become possible - Valiant’s GPS and NavIC-based time servers prevent that, and they have just proven they can do it even when an adversary is jamming the satellite signal.** - **Dual-satellite redundancy as a sovereign shield** - the servers use both GPS and India’s NavIC constellation, so a failure or denial of one system does not blind the grid; this is a direct selling point for Indian defence and critical-infrastructure buyers. - **Jamming-proof, battlefield-tested** - in February 2026 the Indian Armed Forces evaluated the VCL-2156 time server under deliberate jamming and spoofing across two frequency bands; it kept accurate time throughout and rejected fake satellite signals. - **From Turkey to Thailand to Tokyo** - the synchronization portfolio has been deployed at over 250 Turkish substations, inside the Thai utility network for EGAT, and at end-customers including Space Norway and Space One of Japan, proving the products are not just domestic plays. - **Short-listed by the world’s automation giants** - Emerson and Yokogawa have short-listed Valiant for their own synchronization requirements, which means the company is on the radar of the firms that instrument the world’s largest industrial plants. ## 3. Cyber security: a hardware kill-switch for networks that cannot afford to stay connected **Valiant’s cyber-security line goes “beyond the firewall” - it detects intrusions in real time and can physically isolate a compromised network segment, a capability that has already been bought by India’s grid controller and its largest oil explorer.** - **Physical-layer isolation, not just software** - the Network Isolation (Kill) Switch enforces hardware-level separation of network links, so an operator can sever a connection during a ransomware attack or insider threat with a deterministic, out-of-band trigger. - **Honeypots that trace the attacker** - the Network-MouseTrap product acts as a decoy, capturing forensic data, the attacker’s IP address, and country of origin, then triggering audio-visual alarms or automatic failover to a redundant network. - **Deployed in the national nervous system** - the Grid Controller of India (formerly POSOCO), ONGC, and ONGC Videsh have all placed orders, meaning the equipment is already guarding the country’s electricity and oil-and-gas command centres. - **One-way data diodes for the truly paranoid** - the Data Diode enforces a physical, one-directional data flow between networks, so a vaulted storage server can receive backups but can never be reached from the outside. ## 4. Data storage: a vault for data that must survive ransomware, EMPs, and war **Valiant builds India’s first indigenously designed, ransomware-resistant NAS and SAN servers - they combine encryption, air-gap isolation, and electromagnetic-pulse hardening into a single box that a hydro-power PSU has already ordered.** - **1.2 petabytes of protected capacity** - the current storage ceiling is 1,200 terabytes, and the servers are offered in on-site, off-site, and fully off-line configurations so customers can tailor their disaster-recovery posture. - **Quantum-safe and EMP-hardened** - AES-256 encryption is being upgraded to quantum-safe cryptography through a partnership with Fortytwo42 Labs, while the VCL-9000 variant is engineered to survive intentional electromagnetic-pulse attacks and solar storms. - **Air-gap as the last line** - off-line storage means the data is physically disconnected from any network, so even a successful breach of the main data centre cannot touch the backup copy. - **A government energy company signed up** - THDC, a Mini Ratna enterprise under NTPC, ordered ransomware-resilient data-centre equipment in April 2025, showing that the product has moved from concept to commercial deployment inside India’s public-sector energy ecosystem. ## 5. Grid automation and islanding: the self-defence mechanism for unstable power grids **When renewable energy swings destabilize a grid, Valiant’s islanding solution can isolate the trouble-spot before a blackout cascades - and it makes the only Phasor Measurement Unit manufactured in India to do the measuring.** - **The only Indian PMU maker** - Valiant is the sole domestic manufacturer of Phasor Measurement Units, and one of very few globally; its PMU has been type-tested and approved by CSIR-National Physical Laboratory, the country’s measurement standards body. - **Islands as a safety valve** - the Grid Islanding solution detects frequency shifts, phase-angle anomalies, or cyber-threats and can automatically carve a utility into self-contained micro-grids, preventing a local disturbance from pulling down the national network. - **Already inside BHEL’s deployments** - PMU equipment has been supplied to Bharat Heavy Electricals Limited for commercial use, so the product is not a prototype but a fielded system inside one of India’s largest power-equipment integrators. - **Timely after Iberian blackouts** - the company is actively engaging state electricity boards and global utilities with this solution, citing the recent country-wide grid collapses in Spain and Portugal as a vivid reminder of what the product is designed to prevent. # Group structure and partners **Valiant is a debt-free, promoter-led Indian parent with small overseas subsidiaries in the UK and US, and it competes against foreign multinationals by teaming up with Tata’s Tejas Networks and a quantum-security start-up.** - **Simple, debt-free structure** - the company operates as a single segment from its New Delhi factory, with wholly-owned subsidiaries in the UK (which in turn owns a US entity) and an 89%-owned Indian subsidiary, Valiant Infrastructure; the Company and all its subsidiaries maintained its debt free status as of May 2022. - **The Tejas Networks alliance** - a strategic partnership with the Tata Group company lets the two bid as a team for end-to-end IT and OT utility contracts under “Make In India,” positioning them as a combined alternative to foreign MNCs. - **Quantum-safe cryptography partner** - a collaboration with Fortytwo42 Labs, a Pune-based deep-tech start-up, integrates quantum-safe encryption into Valiant’s storage and cyber-security products, giving the company a path to post-quantum readiness. - **European distribution via CXR France** - an MOU with CXR Anderson Jacobson gives Valiant a sales channel into France, neighbouring European countries, and French-speaking North Africa for its cyber-security range. - **Trusted-source status** - the company is registered as a “Trusted Source” by India’s National Security Council Secretariat and was among the first domestic IP/MPLS router makers to earn that approval, a credential that unlocks sensitive government and defence procurement.
