Comprehensive OT Security Services
From passive network analysis to controlled exploitation, we assess every layer of your industrial environment.
OT VAPT
Vulnerability assessment and penetration testing tailored for operational technology. Non-disruptive testing of PLCs, HMIs, RTUs, and engineering workstations
ICS Configuration Review
Security configuration assessment of industrial control systems, including firewall rules, access policies, patch levels, and hardening compliance against IEC 62443.
Network Architecture Review
Purdue Model compliance review, zone and conduit analysis, DMZ architecture assessment, and network segmentation validation for defense-in-depth.
SCADA Penetration Testing
Targeted testing of SCADA systems including master stations, communication channels, and remote terminal units for authentication and access control weaknesses.
Lateral Movement Assessment
Evaluate IT-OT boundary controls and test for lateral movement paths between corporate networks and industrial zones. Identify segmentation gaps and jump-host weaknesses.
Protocol Analysis
Deep analysis of industrial protocols - Modbus TCP/RTU, OPC UA, DNP3, BACnet, EtherNet/IP, PROFINET - for authentication flaws and command injection vulnerabilities.
Our Methodology
6-Phase Safe Assessment Approach
Every phase is designed with operational safety as the primary constraint. No testing proceeds without explicit plant operator authorization
Reconnaissance
Gather architecture documentation, network diagrams, asset inventories, and operational constraints. Define safety boundaries and exclusion zones.
Passive Assessment
Network traffic analysis, protocol identification, and asset discovery using passive techniques only. Zero risk to production operations during this phase.
Active Testing
Controlled vulnerability scanning and service enumeration within agreed maintenance windows. Coordinated with plant operators at every step.
Lateral Movement
Test IT-OT boundary controls, firewall rules, and segmentation effectiveness. Attempt controlled pivoting between network zones to validate defenses.
Reporting
Comprehensive findings report with risk ratings mapped to IEC 62443 security levels. Executive summary, technical details, and photographic evidence.
Remediation Support
Prioritized remediation roadmap with quick wins and long-term architecture recommendations. Retest validation of critical findings post-fix.

OT/SCADA Security — Protecting Critical Infrastructure
We understand Purdue Model, IEC 62443, and the unique constraints of testing live industrial environments safely.
Safe Testing Methodology
Our OT-specific testing methodology ensures zero impact on production processes — using passive scanning, protocol analysis, and isolated lab testing before touching live systems.
Protocol Deep Dive
We test Modbus, DNP3, OPC UA, BACnet, PROFINET, and EtherNet/IP for authentication weaknesses, replay attacks, and man-in-the-middle vulnerabilities.
IT/OT Convergence Assessment
We assess the boundaries between your IT and OT networks — testing DMZ configurations, data diodes, and jump server security to prevent lateral movement from corporate to industrial networks.
IEC 62443 Compliance
Full assessment against IEC 62443 security levels — with gap analysis and remediation roadmap tailored to your operational constraints and maintenance windows.
What clients say about our Managed IT Services
Frequently Asked Questions
Can OT penetration testing be done safely without disrupting production?
Yes. Briskinfosec uses a safety-first methodology specifically designed for operational technology environments. We begin with passive reconnaissance and network analysis before any active testing, use non-intrusive scanning techniques, and work within maintenance windows when required. Our team coordinates with plant operators throughout the engagement to ensure zero disruption to production systems.
What industrial protocols does Briskinfosec test?
Our OT security team has expertise in all major industrial protocols including Modbus TCP/RTU, OPC UA, OPC DA, DNP3, BACnet, EtherNet/IP, PROFINET, IEC 61850, and S7comm. We analyze protocol-level vulnerabilities, authentication weaknesses, and potential for command injection across these communication standards
Does Briskinfosec help with IEC 62443 compliance?
Yes. We provide comprehensive IEC 62443 compliance services including gap assessments, zone and conduit modeling, security level verification, and remediation roadmaps. Our assessments cover all four parts of the standard – general concepts, policies & procedures, system requirements, and component requirements.
Which industries does Briskinfosec serve for OT security?
We serve critical infrastructure sectors globally including energy (oil & gas, power generation, renewables), manufacturing (discrete and process), water and wastewater utilities, transportation (rail, ports, logistics), and building automation systems. With offices in India and UAE, we have deep regional expertise in Middle Eastern critical infrastructure requirements.
