Cybersecurity for SCADA, DCS, PLC and safety systems across manufacturing, power, smart cities and critical public infrastructure. Assessment, design, implementation and monitoring.
In IT, confidentiality usually comes first. On the plant floor, safety and availability do — a control system taken offline to apply a patch can halt a production line or compromise safety, so the tools and tactics that work in the corporate network are often the wrong ones here.
Industrial environments also run equipment measured in decades, not refresh cycles. Controllers that cannot be patched, protocols designed before network security was a consideration, and vendor systems under warranty restrictions all have to be defended as they are, rather than replaced. Meanwhile the air gap most sites believe they have has usually been bridged — by a maintenance laptop, a vendor's remote connection, or the analytics link someone added to feed plant data upstream.
That is the real exposure created by IT/OT convergence: the business network and the process network are already connected, but the security model has not caught up. Routex Technologies closes that gap with controls built around production continuity — so protection is added without becoming the thing that stops the line.
Securing a plant still on the drawing board is a different exercise from securing one that has been running for fifteen years. We work at both ends, and the approach changes accordingly.
On new builds and expansions, security requirements enter at design stage rather than being retrofitted after handover — when changing them is cheapest and least disruptive.
On plants already in production, nothing can be taken offline to be secured. Every control is chosen and sequenced around the operating schedule.
Five engagements, each scoped to a distinct point in an OT security programme. Most clients start with an assessment and progress from there; new-build projects usually start at design.
Security requirements and network architecture for new plants and expansions — zone and conduit design, secure topology, and requirements written into specifications and tender documents, then verified before handover.
Assessment of an operating environment using passive, non-intrusive methods, so nothing is taken offline to be examined. Findings are ranked by operational consequence, not CVSS score alone.
Hands-on deployment inside live production: network segmentation and the IT/OT DMZ, firewall policy, industrial IDS sensor placement, switch and device hardening, and brokered secure remote access.
Standing up monitoring for the plant: detection use cases, sensor placement, tuning for ICS and SCADA protocols, escalation paths between operations and security, and incident playbooks written for an environment where stopping a process is itself a consequential decision.
Practical sessions for the people who run the plant — awareness training for operators and engineers, and tabletop exercises that rehearse an OT incident with plant and security teams together, before a real one arrives.
Building a complete, continuously updated inventory of every PLC, RTU, HMI, and SCADA node on your network using passive monitoring — establishing what you actually have before deciding how to protect it, with no active scanning and no risk to live processes.
Deploying detection tuned to ICS and SCADA protocols rather than generic IT signatures, so unexpected commands, rogue devices, and abnormal process behaviour surface as alerts your operations team can act on immediately.
Designing and implementing segmented zones and conduits along Purdue model boundaries, including a properly governed IT/OT DMZ that stops an incident on the business network from ever reaching the plant floor.
Assessing exposure using safe, non-disruptive techniques chosen specifically for live production environments — prioritising findings by real operational consequence, not by CVSS score alone, since not every vulnerability can or should be patched in OT.
Securing the connections that convergence depends on: brokered remote access for vendors and integrators, zero trust principles applied to industrial networks, and controlled data flows that let business systems consume plant data without opening a path back in.
Mapping your OT security programme to the frameworks that govern your sector — IEC 62443 and NIST SP 800-82, alongside the Indian obligations that actually apply to you, from NCIIPC guidance to the CEA power-sector rules — and translating them into a practical, auditable roadmap rather than a compliance paperwork exercise.
We are deliberately vendor-neutral. Rather than resell a single platform, we assess your environment — protocol mix, site topology, existing toolchain, and in-house capacity — and then recommend and deploy whichever platform fits each use case. In multi-site estates that frequently means different tools at different plants.
Deep OT and IoT network visibility with process-aware anomaly detection, widely deployed across energy, utilities, and heavy manufacturing.
Agentless asset intelligence spanning OT, IoT, and unmanaged devices — useful where a single view across converged environments matters most.
Strong industrial protocol coverage with segmentation and secure remote access capabilities suited to complex, multi-site production estates.
Combines OT asset inventory with vulnerability prioritisation, and integrates cleanly where an organisation already runs Tenable on the IT side.
ICS-specific threat detection and incident response built on dedicated industrial threat intelligence, with deep expertise in critical infrastructure sectors.
Passive discovery works at the protocol layer, so coverage does not depend on which brand is on the cabinet. In practice that means the platforms and protocols already running in most plants.
We map your programme to the standards that genuinely apply to your sector and geography. For most Indian operators that means an international reference standard plus a set of domestic obligations — not the North American rules often quoted by default.
The reference standard for industrial automation and control system security. Defines security levels and the zone-and-conduit model that most OT architectures are designed against.
NIST’s Guide to Operational Technology Security. Practical, control-level guidance written specifically for ICS, SCADA and DCS environments rather than adapted from IT.
A common language for security outcomes across the organisation. Useful mainly as the shared vocabulary between the plant, the security team and the board.
Protection guidance for organisations operating designated critical information infrastructure across sectors such as power, telecom, transport and government.
Cyber security guidelines for the Indian power sector, covering generation, transmission and distribution utilities and their control system estates.
National incident reporting obligations, including the six-hour window for reporting cyber incidents and the associated log retention requirements.
Sector-specific regimes differ. We confirm which apply to your operations during discovery rather than assuming a default set.
We start by establishing ground truth: every device, protocol, and connection on your OT network, gathered passively so production is never interrupted. Most sites find assets and external links here that no one knew existed.
With visibility established, we design the target-state architecture — zones, conduits, and the IT/OT DMZ — and sequence the rollout around your maintenance windows so each change lands without unplanned stoppage.
Once the architecture is in place we operate it: tuned ICS detection, defined escalation paths between plant and security teams, and response playbooks rehearsed against the reality that shutting a process down is itself a decision with consequences.
Operational technology is not confined to factories. The same control systems, protocols and constraints appear across the sectors we serve.
Our IT-side practice covers Zero Trust, identity and access management, SIEM and EDR monitoring, and penetration testing across enterprise infrastructure. Most convergence programmes need both.
