OT/SCADA & Industrial Security Testing. Protect what keeps the world running.
Industrial control systems manage power grids, water treatment, manufacturing, and critical infrastructure. We test SCADA, PLCs, and ICS environments using safe, industry-proven methodologies aligned with IEC 62443 and NIST frameworks.
OT security by the numbers
Industrial systems were designed for reliability, not security. As IT/OT convergence accelerates, legacy systems face modern cyber threats.
Industrial cybersecurity challenges
OT environments face unique security challenges that require specialized expertise. Traditional IT security tools and methods often don't apply.
Legacy systems without security
Industrial equipment was designed decades ago for reliability, not cybersecurity. PLCs and SCADA systems run protocols with no authentication or encryption.
IT/OT convergence risks
Connecting previously air-gapped OT networks to IT infrastructure for efficiency exposes industrial systems to internet-borne threats.
No patching windows
24/7 operations mean no downtime for patching. Systems run for years without updates, accumulating vulnerabilities that can't be fixed.
Safety-critical systems
A security incident can cause physical harm, environmental damage, or loss of life. Testing must be careful, controlled, and never impact safety systems.
Limited visibility
IT security tools don't understand industrial protocols. Many organizations can't even inventory their OT assets, let alone monitor for threats.
OT security skills gap
Finding staff who understand both industrial engineering and cybersecurity is nearly impossible. IT security teams lack OT context.
Vendor dependencies
Industrial vendors control system access and updates. Security testing requires vendor coordination and may void warranties.
NIS2 compliance pressure
NIS2 Directive mandates security for essential entities including energy, water, and manufacturing. Non-compliance means significant fines.
Nation-state threats
Critical infrastructure is a target for nation-state actors. Attacks like Stuxnet, TRITON, and Industroyer show sophisticated OT-specific threats exist.
Benefits of industrial security testing
Specialized OT security assessment identifies risks before they become incidents, without disrupting operations or compromising safety.
Identify OT-specific vulnerabilities
Discover vulnerabilities in PLCs, HMIs, SCADA systems, and industrial protocols that IT security tools miss. Know your actual risk.
Protocol-aware testing of Modbus, DNP3, OPC, BACnet, Profinet, EtherNet/IP
Visibility into risks that could cause operational disruption or safety incidents
Validate network segmentation
Test whether your Purdue Model implementation actually prevents lateral movement from IT to OT and between OT zones.
Zone boundary testing, firewall rule validation, jump host security
Assurance that network architecture protects critical assets as designed
Secure remote access
Vendors and operators need remote access, but it's often insecure. Test VPNs, jump hosts, and remote maintenance paths.
VPN security, authentication testing, session management, credential handling
Reduced risk from remote access, the most common OT attack vector
NIS2 & IEC 62443 compliance
Generate audit evidence for NIS2, IEC 62443, NERC CIP, and sector-specific requirements. Map findings to compliance frameworks.
Control testing mapped to IEC 62443 security levels and requirements
Compliance documentation, reduced regulatory risk, audit readiness
Improve incident detection
Identify gaps in monitoring and detection capabilities. Many OT attacks go undetected for months. Know if you'd catch an intruder.
Detection testing, log analysis, alert validation, SIEM integration review
Confidence in your ability to detect and respond to OT threats
Build internal capability
Knowledge transfer and training for your OT teams. Build security awareness without requiring deep security expertise.
Training on OT security best practices, secure configuration guidance
Reduced dependency on external experts, improved security culture
Comprehensive OT testing categories
From initial assessment to active penetration testing, our services tailored to your industrial environment and risk tolerance.
OT Security Architecture Review
Comprehensive assessment of your OT environment including network architecture, segmentation, asset inventory, and security controls. Foundation for all further testing.
Learn MoreSafe OT/SCADA & industrial security testing roadmap
Industrial environments require careful, deliberate testing. Our methodology prioritizes safety while thoroughly assessing security.
Scoping & safety planning
Define scope, identify critical systems, establish safety boundaries, and coordinate with operations. No testing proceeds without safety approval.
Passive reconnaissance
Non-intrusive discovery of OT assets, network topology, and protocols. Listening only: no packets sent that could impact operations.
Configuration review
Analyze configurations of firewalls, PLCs, HMIs, and network equipment. Identify misconfigurations and insecure settings without active testing.
Controlled active testing
Careful, coordinated active testing with operations awareness. Each test is planned, communicated, and has rollback procedures.
Lab simulation (optional)
For aggressive testing, replicate environment in our ICS lab. Destructive tests, malware simulation, and full exploitation without production risk.
Reporting & roadmap
Comprehensive reporting with IEC 62443 mapping, prioritized remediation, and security improvement roadmap aligned with operational constraints.
OT assessment deliverables
Actionable deliverables aligned with industrial security standards and operational realities.

Frequently asked questions
Answers to common questions about OT/SCADA penetration testing.
Safety and operational continuity are our top priorities. We use passive reconnaissance for most discovery, coordinate active testing with your operations team, and never test safety systems in production. For aggressive testing, we offer lab replication. Our methodology is designed for 24/7 industrial environments where downtime is not an option.
We do not perform active testing on safety systems in production environments. SIS testing is conducted only in our ICS lab using replicated configurations, or through configuration review and passive analysis. Safety system integrity is never compromised during our assessments.
Yes. Our OT security team includes engineers with industrial automation backgrounds, IEC 62443 certifications, and experience in energy, manufacturing, and critical infrastructure. They understand not just the security, but the engineering context, why systems are configured as they are.
We coordinate with vendors when required and respect maintenance agreements. However, security testing is your right as the asset owner. We can work within vendor-imposed constraints or help you negotiate appropriate security testing provisions in vendor contracts.
We map findings to IEC 62443 (primary industrial standard), NIST SP 800-82, NIS2 Directive requirements, NERC CIP (energy sector), and sector-specific frameworks. Our reports provide the evidence auditors and regulators need.
Yes. We deploy on-site with equipment that operates independently of internet connectivity. For truly air-gapped environments, we bring all necessary tools and work entirely offline. Test results are securely transferred via approved methods.
Legacy systems are common in OT. We identify vulnerabilities but focus recommendations on compensating controls - network segmentation, monitoring, access control - rather than patching when it's not feasible. We understand the reality of 20-year-old PLCs.
A typical single-site assessment takes 3-5 weeks including scoping, passive reconnaissance, active testing, and reporting. Larger environments or multiple sites require more time. We provide accurate estimates after understanding your environment.
Yes. Beyond assessment, we offer OT-specific monitoring through our SOC, continuous vulnerability assessment, and periodic retesting. OT threats evolve, your security should too.
We have deep experience in energy/power generation, water/wastewater, manufacturing, oil & gas, transportation, and building automation. Each sector has unique requirements and threats. We tailor our approach accordingly.
