Secure SCADA, DCS, PLCs and plant networks — without stopping production.
Invield has a proven track record of securing operational technology for its partners in the energy & power, manufacturing, aviation and defence sectors. We combine industrial-protocol expertise with a safety-first, passive-first method, so you get visibility and a clear risk-reduction roadmap without disrupting operations.

Plant networks were built for availability and safety, not for connectivity. As IT and OT converge — remote access, cloud historians, vendor support links — attackers can reach systems that control physical processes.
PLCs, RTUs and HMIs often run for decades on unsupported operating systems that cannot simply be patched or scanned.
Weak segmentation lets ransomware spread from the office network to the plant floor.
Always-on remote desktop and shared vendor accounts are a common entry point into control systems.
A cyber incident in OT can halt production, damage equipment or endanger people — and aggressive testing can cause the very outage you want to prevent.
From a first assessment to continuous monitoring — delivered by engineers who understand industrial processes.
Build an accurate inventory of PLCs, RTUs, HMIs, engineering workstations and network devices using passive traffic analysis.
Assess your control-system environment against IEC 62443 and NIST SP 800-82, define zones and conduits, and rank risks by safety and business impact.
Review your architecture against the Purdue reference model and design a practical IT/OT DMZ and firewall rule set.
Vulnerability assessment and penetration testing tailored to industrial systems — passive first, and active testing only with your approval, in maintenance windows or on test benches.
Secure how employees and OEM vendors reach your plant: jump hosts, MFA, session recording and least-privilege access.
Continuous detection for control networks, integrated with Invield SIEM and our 24/7 SOC, with alerts tuned to industrial protocols and processes.
Prepare plant, IT and management teams to respond to a cyber incident safely, and get hands-on help if one happens.
Build an OT security programme that meets sector requirements and stands up to audit.
Invield serves partners across critical and industrial sectors, adapting every engagement to the safety rules and regulators of that industry.
Generation, transmission, distribution and renewable plants — SCADA, substation automation (IEC 61850) and control centres.
Discrete and process manufacturing — PLC/DCS networks, MES, historians and OEM remote support.
Airport and aviation operational systems — baggage handling, airfield and building management systems and their supporting networks.
Defence manufacturing and establishments — isolated and air-gapped networks, secure engineering environments and supply-chain risk.
Agree sites, systems, contacts and rules of engagement with operations and safety teams.
Capture and analyse network traffic to map assets and communications — no impact on live processes.
Review architecture, access and configurations against IEC 62443 and rank risks by consequence.
Where approved, validate findings on test benches or during maintenance windows.
Deliver a prioritised, budget-aware roadmap and support your teams through remediation.
Optional continuous OT monitoring with Invield SIEM and 24/7 SOC.
Our assessments map to recognised OT security frameworks and Indian sector requirements, and our engineers work with the industrial protocols your plant actually uses.
