Chennai, Tamil Nadu · Digital TechSafe Engineering Pvt Ltd
Digital TechSafe Engineering designs commodity mini PC boards and high-speed networking platforms with AI embedded at the board level, licenses Vishnu HomeGuard AI network security for India and world markets, and offers senior consulting on large-scale systems, cybersecurity and business readiness.
Platforms
4x4 and 5x5 NUC-class boards with soldered LPDDR5X, dual 2.5GbE and an on-package NPU. Built for edge retail, kiosks, industrial control and desktop fleets at commodity price points.
Switch and DPU carrier boards from 100G to 800G, with 32-layer low-loss stackups qualified in-house. Line-rate inference sits next to the pipeline, not behind it.
Partnership · Vishnu HomeGuard Pty Ltd, Australia
Firewalls protect the perimeter, but they do not explain behaviour. Vishnu HomeGuard observes long-duration network traffic with a deep-learning engine and turns it into plain-language summaries of what every smart device in a home is actually doing — building device profiles that show what is normal and what needs attention.
Digital TechSafe Engineering has secured proprietary product licensing from Vishnu HomeGuard Pty Ltd (Australia) to manufacture, localise and sell HomeGuard products in India and across world markets. The ongoing engagement covers Indian assembly on our own board platforms, joint engineering on the AI observation engine, and support and distribution for Indian and Western channels.
Founder
Retired Professor of Computer Science and Engineering at IIT Madras, and former Scientific Secretary in the Office of the Principal Scientific Adviser to the Government of India. Widely regarded as the father of the Internet in India through ERNET, and Chief Architect of the National Knowledge Network. He is a published author of several academic journals and books of repute.
Digital TechSafe Engineering is his effort to build self reliance in technology hardware-up in India — advancing indigenous manufacturing capability from board design through to systems that serve Indian and Western markets alike.
Consulting
Prof. Raghavan offers selective consulting engagements to governments, operators, enterprises and institutions through Digital TechSafe Engineering.
Architecture and review for national-scale networks, data centres and research backbones — capacity planning, topology, routing policy and operations readiness.
Threat modelling, security architecture, incident readiness and assurance programmes for critical infrastructure, enterprises and public institutions.
Placing models where the data is — embedded inference in networks and devices, data pipelines, model governance and evaluation of AI in production systems.
Board-level assessment of modern business and cyber risk: resilience, regulatory exposure, technology strategy and digital sovereignty.
Capability
Full schematic, layout, SI/PI and thermal simulation done by an in-house team in Chennai — no outsourced reference-design relabelling.
A board-level runtime that pins quantised models to the on-board NPU with deterministic latency, shipped and signed with the firmware.
SMT, AOI, X-ray and burn-in through qualified Indian EMS partners under our own test programs and traceability.
BIS and CE/FCC/UKCA paths run in parallel from first article, so the same board ships into Indian and Western channels.
Multi-sourced BOM with bonded buffer stock and 36-month lifecycle commitments written into the supply agreement.
Open, auditable boot firmware with a customer-owned root of trust. No opaque blobs in the boot path.
Supply
Every platform ships under a written supply agreement: dual-sourced critical components, bonded buffer inventory held in India and the Netherlands, and traceability from reel to serial number. Customers get allocation certainty instead of quarterly surprises.
Every critical line item has a qualified second source before first production.
8–12 weeks of finished-board buffer held for contracted customers.
Reel-level traceability, AOI and X-ray records tied to each serial number.
India and EU stocking points for short lead times in both markets.
Five-year roadmap
Year 1
First silicon partners, DTSE-M1 mini PC platform sampling, Chennai design centre at 40 engineers, Vishnu HomeGuard launched in India.
Year 2
Volume production of mini PC boards; DTSE-N4 100G/400G networking boards enter qualification.
Year 3
Domestic substrate and 32-layer PCB sourcing; embedded AI runtime v2 with customer model pipelines.
Year 4
800G networking platforms in production; Western channel partners under long-term supply contracts.
Year 5
India-owned chipset IP and a fully domestic board supply chain from substrate to burn-in.
We work with OEMs, network operators, system integrators, institutions and distribution partners — from schematic review and advisory through contracted volume supply.
