Valiant Communications Limited announced the successful completion of evaluation testing with the Indian Armed Forces for its Hardware-Based Network Isolation (Kill) Switch Equipment. The equipment represents a significant advancement in cyber resilience technology for mission-critical operational environments.

Equipment Capabilities and Testing Results

The Hardware-Based Network Isolation (Kill) Switch Equipment is designed to provide purpose-built, deterministic, hardware-enforced network separation for mission-critical operational environments. The solution focuses on three core areas: cyber resilience, secure segmentation, and network isolation with operational continuity during cyber incidents.

The evaluation validated the solution's ability to enforce immediate physical-layer isolation of designated network links and zones. This capability supports emergency response actions during cyber incidents, insider-threat containment, or physical security events. Specific technical data and operational procedures remain undisclosed due to security considerations.

Management Commentary

CEO Inder Mohan Sood commented on the development, stating that this successful evaluation marks an important milestone in strengthening cyber resilience for mission-critical systems and environments requiring deterministic behavior and predictable failover outcomes. He emphasized that in complex operational environments where downtime, ambiguity, or uncontrolled lateral movement can have real-world consequences, hardware-enforced isolation provides an additional layer of assurance beyond traditional firewall and software controls.

Sood highlighted that a key element in modern operational resilience is the ability to contain threats in real time without depending solely on firewall and software controls that may be degraded during advanced intrusions.

Target Applications and Integration

The 'Beyond the Firewall' Hardware-Based Network Isolation (Kill) Switch Equipment is designed for deployment across high-consequence environments. Target applications include:

• Defence platforms and shore establishments
• Operational command centres
• Industrial and utility facilities
• Secure data centres
• Sensitive digital assets requiring segmentation integrity and rapid containment

The hardware architecture supports integration with existing security and operations ecosystems, including firewalls, intrusion detection systems, SIEM/SOC, and physical intrusion detection. The system provides out-of-band activation options such as multiple user triggers and serial control interfaces based on customer requirements.

Valiant Communications Limited has successfully validated its advanced GPS timing solution for the Indian Armed Forces, marking a significant milestone in indigenous defense technology development. The company completed field evaluation of its VCL-2156 Dual-Band GPS and NavIC NTP Time Server on February 10, 2026, demonstrating robust performance under challenging operational conditions.

Field Evaluation Results

The comprehensive evaluation assessed system performance across multiple scenarios to validate operational readiness for military applications.

The NTP server maintained continuous and accurate synchronization for connected network clients under all test conditions, demonstrating strong immunity to both single-band and dual-band interference. The platform's anti-spoofing intelligence effectively detected and rejected falsified satellite signals, ensuring system time and positional data remained uncompromised.

Indigenous GNSS Security Architecture

The VCL-2156 represents a comprehensive approach to secure timing solutions for defense and critical infrastructure environments. The system supports dual-band L1 and L5 reception across multiple satellite constellations.

Technical Capabilities

• Multi-constellation support: GPS, GLONASS, Galileo, and NavIC
• Dual-band operation: L1 and L5 frequency reception
• Anti-spoofing intelligence: Algorithm-driven signal verification
• Interference immunity: Advanced jamming resistance
• Autonomous recovery: Automatic restoration post-interference

Strategic Importance for Defense Applications

According to Mr. Inder Mohan Sood, CEO and CTO of Valiant Communications Limited, accurate and trustworthy time serves as a foundational requirement for modern defense and critical infrastructure systems. The successful proof of concept demonstrates the VCL-2156's ability to sustain precise time synchronization even under sophisticated GNSS threats.

Trusted GNSS timing plays a vital role across multiple sectors:

• Defense operations and military systems
• Aviation and air traffic control
• Power grid synchronization
• Banking and financial networks
• Telecommunications infrastructure
• Financial trading platforms

Advanced Security Framework

The VCL-2156 integrates comprehensive GNSS security measures designed to address modern threat environments.

The successful validation confirms the system's ability to deliver robust, secure, and dependable time synchronization in challenging operational scenarios, reinforcing Valiant's capability to support defense and national security programs with high-reliability indigenous solutions.
