Assessment Scope

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.

SCADA Penetration Testing

Targeted testing of SCADA systems including master stations, communication channels, and remote terminal units for authentication and access control weaknesses.

ICS Configuration Review

Security configuration assessment of industrial control systems, including firewall rules, access policies, patch levels, and hardening compliance against IEC 62443.

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.

Network Architecture Review

Purdue Model compliance review, zone and conduit analysis, DMZ architecture assessment, and network segmentation validation for defense-in-depth.

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.

Compliance & Standards

Aligned to Global OT Security Frameworks

Our assessments map to international and regional standards for industrial cybersecurity.

Why Briskinfosec

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.

Success Story

Real Results, Real Impact

Major Indian Power Utility

Energy & Utilities · 15,000+ employees
OT/SCADA Assessment
Challenge

Operating 200+ SCADA endpoints across 12 substations with no visibility into OT-specific vulnerabilities. Regulatory audit approaching in 60 days.

Our Approach

Briskinfosec deployed passive OT network monitoring across all substations, conducted non-intrusive vulnerability assessments of PLCs and RTUs, and mapped all IT/OT convergence points.

Result

Identified 156 OT-specific vulnerabilities including 18 critical findings in legacy Modbus/TCP implementations. Passed regulatory audit with zero findings. Achieved 100% OT asset visibility for the first time.

“Briskinfosec understood OT environments in a way traditional IT security firms never could. Their non-intrusive approach meant zero production downtime during assessment.”

FAQs

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.
