OT/SCADA/ICS
Penetration Testing.

Industrial control systems, SCADA environments, and critical infrastructure demand a specialist approach. HackLabs brings deep OT expertise to uncover vulnerabilities before attackers exploit them.

// The OT Security Challenge

Your operational technology is now in scope for attackers.

The convergence of IT and OT networks has exposed industrial control systems to threats once confined to enterprise IT. SCADA systems, PLCs, HMIs, and industrial protocols were designed for reliability — not security. HackLabs' OT specialists assess these environments with the care required to find real vulnerabilities without disrupting operations.

// What We Cover
  • SCADA system security assessment
  • PLC and HMI vulnerability analysis
  • Industrial protocol testing (Modbus, DNP3, IEC 61850, PROFINET)
  • OT/IT network segmentation review
  • Remote access and historian assessment
  • Engineering workstation security review
  • ISA/IEC 62443 gap assessment
  • Purdue model zone and conduit analysis
  • Safety instrumented system (SIS) review
  • Asset inventory and exposure mapping
// Capabilities

What we assess

SCADA & HMI Testing

Assessment of SCADA servers, HMI workstations, historian databases, and web-based interfaces for authentication flaws, injection vulnerabilities, and insecure configurations.

PLC & Controller Security

Analysis of programmable logic controllers, RTUs, and field devices for firmware vulnerabilities, unauthorised access paths, and insecure programming interfaces.

Industrial Network Assessment

Mapping and testing of OT network architecture including zone segregation, firewall rulesets, and inter-zone communication paths aligned to the Purdue model.

Protocol Security Analysis

Testing of industrial protocols including Modbus, DNP3, IEC 61850, OPC-UA, PROFINET, and EtherNet/IP for authentication bypass, replay attacks, and command injection.

Remote Access Review

Assessment of remote connectivity solutions including VPNs, jump servers, and vendor remote access tools that provide pathways into OT environments.

ISA/IEC 62443 Assessment

Gap analysis against ISA/IEC 62443 security levels, providing a roadmap for achieving the security target levels appropriate for your industrial environment.

// Methodology

Our engagement process

01

Scoping & Safety Review

We work with your OT team to define safe testing boundaries, identify critical systems, and establish rules of engagement that prevent operational disruption.

02

Passive Discovery

Non-intrusive network capture and asset discovery maps your OT environment without sending active probes that could affect operational equipment.

03

Active Assessment

Targeted testing of identified systems using OT-safe techniques. We replicate attacker techniques while respecting the operational constraints of your environment.

04

Reporting & Remediation

Findings are risk-rated in the context of operational impact. Remediation guidance is practical and accounts for the long lifecycle of industrial systems.
