Government OT Networks: Zero Trust Protection

Why Government OT Needs Zero Trust

AI-Resistant Zero-Trust Security for Government OT

What we protect

  • ICS/SCADA, PLC/DCS, BMS, substations, WTP/WWTP, ports, data-center OT, and defense facilities.

How it works (core controls)

  • Undiscoverable OT: no open ports, cloaked assets, default-deny micro-segmentation.
  • Strong identity everywhere: MFA and phishing-resistant authentication for users, devices, and workloads.
  • Just-in-time access: per-session, least-privilege pathways with no flat networks or VPN sprawl.
  • Protocol-aware zoning: policy-as-code for Modbus, DNP3, OPC UA, IEC 61850, BACnet, and more.
  • Continuous verification: device posture, geo/time, and user risk checks with auto-revoke on anomalies.

Why it’s AI-resistant

  • Shrinks the attack surface by removing discoverable services and reducing AI-driven reconnaissance opportunities.
  • Encrypted, ephemeral access paths resist credential stuffing and automated exploitation attempts.
  • Inline anomaly detection and deception beacons help flag bot-led probing early.

Government advantages

  • Supports Zero Trust mandates and aligns with IEC 62443 and NIST frameworks.
  • Works in air-gapped and low-bandwidth environments with GovCloud or on-prem deployment options.
  • Enables fast, OT-safe rollout through gateways without rip-and-replace.
Network Cloaking

Hide critical systems from reconnaissance and attack.

Passwordless MFA

Prevent phishing and credential theft.

Secure Remote Access

Maintain access with strict control and least privilege.

Microsegmentation

Block lateral movement and isolate cyber risk.

Use-Cases & Impact

Where it makes a difference

  • High-value, high-risk OT: power and substations, water/WTP/WWTP, oil and gas, metros and rail, ports, airports, defense depots, and data-center OT/BMS.
  • Legacy and mixed-vendor sites: brownfield PLC/DCS, serial/IP bridges, vendor laptops, and shared jump hosts.
  • Remote and third-party access: OEM maintenance, field crews, and seasonal contractors.
  • Regulated environments: audits against IEC 62443, NIST CSF, NIST 800-82, and national Zero Trust mandates.
  • Low-bandwidth or intermittent links: remote stations, pump houses, and feeder pillars.

Use-cases

  • Undiscoverable OT zones: cloak PLCs and HMIs, eliminate open ports, and enforce default-deny micro-segmentation.
  • Just-in-time vendor access: session-based access to a single asset and protocol only.
  • Privileged task isolation: break-glass access with MFA and command logging.
  • Protocol-aware policy: allow-list DNP3, IEC 61850, BACnet, and OPC UA while blocking everything else.
  • Site-to-SOC assurance: posture checks, geo/time/risk gates, and automated revoke on anomalies.
  • Ransomware blast-radius control: contain lateral movement across OT/IT boundaries.
  • Air-gap bridging: ephemeral encrypted tunnels without exposing services.

Impact (measurable KPIs)

  • Attack surface: reduce exposed services by more than 95%, with zero open ports on OT assets.
  • Vendor access time: reduce turnaround by 50 to 80% by removing VPN and jump-server bottlenecks.
  • Lateral movement: restrict spread through per-asset micro-segmentation.
  • Detection and response: improve MTTA and MTTR by 30 to 60% with inline verification and kill-switch controls.
  • Compliance readiness: faster IEC 62443 and NIST audit closure with fewer exposure-related findings.
  • Operational uptime: reduce disruption and avoid rip-and-replace for legacy systems.
Compliance and standards alignment with Indian government requirements

Compliance & Standards Alignment (Government & India)

Global frameworks we map to

  • IEC 62443: policies, zones and conduits, RBAC, secure remote access, and patch/change control.
  • NIST: SP 800-82 for ICS, SP 800-53 for control baselines, and SP 800-207 for Zero Trust.
  • ISO/IEC 27001:2022 and 27002: control objectives, with sector add-ons such as ISO 27019 for energy.

India-specific alignment

  • CERT-In Directions (April 2022): supports 6-hour incident reporting, 180-day log retention, time synchronization, and incident taxonomy requirements.
  • NCIIPC guidance: risk-based controls, segmentation, least privilege, and continuous monitoring.
  • MeitY/NIC GI Cloud (MeghRaj): supports on-prem or in-country deployment, data residency, and audit logging.
  • CVC/DoE auditability: immutable logs, change trails, and vendor access records for compliance audits.

What auditors get out of the box

  • Control-to-standard traceability matrix across IEC 62443, NIST, and ISO controls.
  • Asset inventories, data-flow inventories, zone and conduit diagrams, and policy-as-code exports.
  • Evidence packs including MFA and JIT session records, configuration baselines, and vulnerability/exception registers.

Why it helps

  • Faster audit closure, fewer exposure findings, and clear proof of Zero Trust by design for ministries, PSUs, and critical infrastructure operators.
