Security enforced by hardware. Intelligence that stays in India.
From the ARKA™ DD-100 data diode to cross-domain guards, secure media kiosks, quantum-safe encryptors and sovereign AI, we build the specialised security products that India's government, PSU, defence and critical-infrastructure networks now need.
Five product families, one goal: protect what matters most.
We start where conventional firewalls stop, with physical one-way enforcement, and build out into media control, cryptography, OT visibility and AI.
Unidirectional & Cross-Domain
Hardware that controls which way data is allowed to move between networks of different trust levels, and what crosses the boundary.
3 productsMedia & Endpoint Security
Stop malware arriving on USB drives, CDs and shared peripherals, which is how most air-gapped plants get infected.
2 productsCryptography & Quantum-Safe
Key protection and link encryption, with post-quantum algorithms ready for the National Quantum Mission era.
2 productsOT / ICS Security
Visibility and controlled access for SCADA, PLC and substation networks in power, oil & gas, water and transport.
2 productsAI & Security Software
AI-driven detection, compliance and analysis platforms, deployed on-premise in India and never dependent on foreign clouds.

Talk to our teamARKA™ DD-100 Data Diode
A dedicated hardware appliance that enforces strictly one-way UDP data transfer between two networks. Operational data gets out; nothing gets back in.
- Hardware-enforced isolation, with no return path to attack or mis-configure
- Unidirectional UDP, minimum 70 Mbps throughput
- 2 x 1 GbE RJ-45 interfaces; management / console (V24) port
- 19" rack-mountable; 230 VAC, 50 Hz; 0 to +50 °C
- 5-year licences, warranty, support, updates and security patches

View product →ARKA Sentinel AI-SOC
AI-driven SIEM and SOAR, hosted in India, with CERT-In 6-hour reporting and 180-day log retention built in.
View product →Indian regulation has changed the security baseline.
CERT-In's 6-hour reporting rule, the DPDP Act, CEA power-sector guidelines, RBI and SEBI frameworks and the National Quantum Mission all point to the same requirements: segregate, monitor, encrypt, and keep data in India.
Power & Utilities
Generation, transmission and distribution companies under CEA cyber-security guidelines must segregate OT, control removable media and monitor SCADA.
Defence & Strategic
Classified networks need hardware-enforced separation, controlled cross-domain exchange and AI that never leaves the premises.
Banking, Financial Services & Insurance
RBI, SEBI and IRDAI frameworks call for SOC monitoring, strong key management, encryption in transit and fraud defence.
Railways, Metro & Aviation
Signalling, traction and airport systems need one-way monitoring feeds and secure vendor maintenance access.
Built for environments where security is not optional.
Security by design
Protection enforced in hardware where it matters most, not left to configuration alone.
OEM accountability
As the OEM, ARKA stands behind licensing, warranty, updates and security patches.
Made for India
Specified for Indian conditions (230 VAC, 50 Hz, 0 to +50 °C), with Indian-language AI and data kept in India.
Tender-ready
5-year licences in the end customer's name, OEM authorisation and documentation for government procurement.
