ISO 27001, ISO 9001, ISO 20000-1 Certified Cyber Range & Security Assessment Firm in India

Securing India's Critical Infrastructure, One System at a Time

Zettawise Consulting Pvt. Ltd. is an ISO 27001, ISO 9001, and ISO 20000-1 certified cybersecurity organisation specialising in the protection of national critical infrastructure. As a deep-tech company with a sharp focus on IT and Industrial Control Systems (ICS) security, we help governments and large enterprises strengthen their cyber posture, meet international compliance standards, and build lasting resilience against evolving threats.
Our work sits at the intersection of national security and applied engineering. Rather than reselling third-party tools, we build our own platforms — an indigenous Cyber Range, a counter-UAS command system, and a post-quantum cryptography practice rooted in foundational academic research — because the infrastructure we're asked to protect is too sensitive to secure with anything less than technology, we control end to end.
We are proud members of the joint workforce of RRU–SASTRA under the Ministry of Home Affairs, Government of India, operating under the aegis of the "AtmaNirbhar and AtmaSurakshit Bharat Mission." In 2025, we became an accredited training body of the Quality Council of India under the Conformity Assurance Framework (CAF) Scheme of NCIIPC — one of only a handful of organisations recognised for IT/ICS security training in the country. We are also a QCI-empanelled consulting agency, having served national and foreign government departments and ministries directly.

Building Resilient Aerial Systems for a Secure Future

At Zettawise Consulting, we safeguard Unmanned Aerial Systems (UAS) across mission-critical deployments through advanced forensic analysis, resilience assessments, and threat detection — strengthening aerial security, reliability, vulnerability management, and post-incident traceability.
Our flagship platform in this space is MEGHDUT C³, a CEMA-enabled counter-UAS command-and-coordination layer built for contested electromagnetic environments — not a standalone attack tool, but a command layer that integrates sensing, understanding, and coordinated response into a single operational picture for contested airspace over critical infrastructure and sensitive installations.
The platform's operational model moves through five stages — Sense, Understand, Decide, Coordinate, Document — and is designed around three deployable form factors: a backpack-portable Scout unit for forward sensing, a Mobile vehicle-mounted unit for extended coverage, and a Command node for regional aggregation. Development follows a phased capability roadmap, from demonstrated prototype toward full operational deployment, with requirements captured in a structured Operational Requirement Document for downstream procurement use.
Zettawise leads the software layer of this joint development effort — detection logic, MAVLink injection, and a React-based command console — working alongside RF hardware specialists who lead HF/VHF/UHF direction-finding, signal decoding, and antenna fabrication. It's a partnership model where each side contributes to its area of strength, moving the platform steadily toward full CEMA-enabled operational capability.

What Sets Us Apart

At the heart of our capability is India's advanced, indigenous OT security testing facility — a hybrid Cyber Range combining real physical assets (PLCs, SCADA, RTUs) with emulated infrastructure. This unique environment lets us build digital twins of client OT networks, run red-team/blue-team exercises, and simulate real-world attack scenarios — all without any risk to live operations. It's powered by our own indigenously developed, AI-enabled platforms, DiZi-Twin and DiZi Tandav.

Our OT/ICS security capability is standards-aligned by design, spanning SCADA, PLCs, PMUs, RTUs, protection relays, and substation automation. That includes OT asset inventory and zone/conduit modelling per IEC 62443-3-2, Security Audit Trail assessments per the CEA Cyber Security Guidelines 2021, NCRF BTC Level 1 compliance work, and automated Critical Information Infrastructure (CII) identification per NCIIPC guidelines — alongside product testing across the full idea-to-production lifecycle.

Our Cyber Range has also become a national training platform. We've delivered OT/ICS cybersecurity and AI training with IIT Kharagpur alongside GRID-INDIA and CSIRT-Power (CEA), reaching 100+ delegates across State and Regional Load Despatch Centres. With IIT Bhilai, we're developing an advanced FinTech cybersecurity testbed for R&D and capacity development under NM-ICPS. We've contributed OT use-case demonstrations at the NCIIPC CII SECEX 2024 workshop alongside RRU during National Cyber Security Month, and conducted tabletop exercises with SBI, IIT Bhubaneswar, and Grid Controller of India.

Our solution portfolio spans five pillars:

Cyber Range — indigenous OT testing and training, recognised by SASTRA (RRU), Ministry of Home Affairs
Security Assessment — end-to-end VA/PT for IT and OT environments, including ICS/SCADA protocol testing and legacy system analysis
UAS Resilience — advanced forensic analysis, attack-pattern assessment, and security validation for autonomous aerial systems, anchored by our MEGHDUT C³ platform.
Managed OT SOC — 24x7 monitoring and incident response purpose-built for industrial environments
Post-Quantum Cryptography — a specialised line of business under the direction of Padmashri Dr. Bimal Kumar Roy, with a foundational research lineage from the Indian Statistical Institute, covering quantum algorithm expertise, public-key cryptography vulnerability assessment, transition to quantum-resistant cryptography, code-based and lattice-based cryptography, comprehensive key management, and stream cipher resilience
Consulting & Advisory — ISMS implementation, regulatory compliance (CEA, NCIIPC, CERT-In, IEC 62443), and QCI-accredited training

Our Mission

Zettawise strengthens national critical infrastructure by securing, modernising, and building resilient, indigenous digital systems across strategic sectors — combining subject matter expertise, national security alignment, and global best practices to safeguard what matters most.
We believe critical infrastructure security cannot be outsourced to technology we don't fully understand or control. That conviction is why we build our own platforms rather than integrate someone else's: an indigenous Cyber Range that lets us test OT environments without risking live operations, a counter-UAS command system engineered for India's own contested-airspace requirements, and a post-quantum cryptography practice grounded in decades of domestic academic research rather than imported frameworks. Every one of these is built to serve the specific operational realities of Indian power grids, financial institutions, defence networks, and government systems — not retrofitted from capability designed for a different threat landscape.
Our mission also extends beyond any single engagement. Through our accredited training programmes, our R&D partnerships with IIT Kharagpur and IIT Bhilai, and our capacity-development work with State and Regional Load Despatch Centres, we're building the next generation of OT/ICS security expertise within the country — because resilient infrastructure ultimately depends on a resilient workforce that understands it. Whether we're assessing a substation's SCADA network, validating a counter-UAS system over sensitive airspace, or advising a ministry on regulatory compliance, the same standard applies security that is indigenous by design, rigorous by standard, and accountable to the nation it protects.
