Operational Technology Penetration Testing

Keep plants, substations, and facilities running, while proving what an attacker could really do. Packetlabs performs OT testing designed for ICS/SCADA environments, prioritizing safety, availability, and real-world exploitability (not checklist findings).

Test ICS & SCADA Without Disrupting Operations

OT environments have different rules: uptime matters, legacy protocols persist, and patched isn't always possible. We work with your team to define safe testing windows, validate segmentation and remote access controls, and identify attack paths that could impact safety or production. You get actionable remediation guidance,mapped to operational risk so security improvements stick without breaking the plant."

What We Validate in OT Environments

OT security fails when assumptions go untested. This engagement focuses on the controls that actually stop attacker movement in real industrial networks.

Safety-First Test Planning

Define safe methods and windows for each target so availability and operational safety stay protected without weakening test realism.

Segmentation & Zone Validation

Verify that IT/OT boundaries, VLANs, and firewalls truly prevent lateral movement between zones and identify hidden bridges.

Learn about the importance of OT cybersecurity

Remote Access & Vendor Pathways

Test VPNs, jump hosts, remote tooling, and vendor access for credential abuse, misconfigurations, and privilege escalation paths.

Learn more about third-party risk management

Protocol-Aware Attack Simulation

Assess exposure across industrial protocols and services with techniques appropriate for OTâ€”prioritizing exploitability and impact.

Learn how pentesting keeps operational tech secure

Identity & Privileged Access Risk

Identify over-permissioned accounts, shared credentials, and weak authentication that turns identity into the OT blast radius.

External Exposure & Asset Discovery

Find internet-facing OT-adjacent assets and management interfaces that expand risk then validate how quickly attackers can pivot.

OT Cybersecurity Assessment vs. Cyber Maturity Assessment

	OT Cybersecurity Assessment	Cyber Maturity Assessment
Primary Objective	Assess the security posture and resilience of operational technology environments	Evaluate the overall maturity of an organization’s cybersecurity program
Environment Focus	Industrial control systems (ICS), SCADA, PLCs, manufacturing systems, utilities, critical infrastructure	Enterprise IT systems, governance structures, risk management, and compliance programs
Scope	Network segmentation, remote access into OT, legacy systems, industrial protocols, and asset visibility	Policies, procedures, security strategy, incident response planning, and control alignment
Risk Perspective	Operational disruption, safety impact, production downtime, and critical service interruption	Business risk, regulatory exposure, data protection, and organizational resilience
Framework Alignment	IEC 62443, NIST SP 800-82, sector-specific OT guidance	NIST CSF, ISO 27001, CIS Controls, SOC 2, and similar enterprise frameworks
Technical Depth	Technical validation of industrial networks, configurations, and access controls	Strategic evaluation of governance, oversight, and security program effectiveness
System Constraints	Considers legacy, safety-critical, and uptime-sensitive environments	Typically evaluates modern IT environments and enterprise controls
Threat Focus	Nation-state targeting, ransomware impacting operations, insider threats within OT	Data breaches, ransomware, governance gaps, and compliance shortcomings
Impact if Gaps Exist	Physical disruption, halted production, safety incidents	Regulatory penalties, financial loss, reputational damage
Best Suited For	Organizations operating manufacturing, energy, utilities, healthcare, or critical infrastructure systems	Organizations looking to benchmark and improve their overall cybersecurity maturity
Key Question Answered	“How secure and resilient are our operational systems?”	“How mature and effective is our cybersecurity program?”

OT Cybersecurity Assessment: Key Outcomes

Move from we think it's segmented to we can prove it. These are the outcomes OT leaders use to reduce real attacker risk.

Proven IT/OT Separation

Demonstrate whether boundaries actually stop lateral movement, and where attackers can still cross zones.

Explore Infrastructure Testing

Reduced Remote Access Risk

Identify and close the easiest vendor and remote operator pathways before they become the incident root cause.

Fewer High-Impact Attack Paths

Prioritize fixes that prevent safety/availability impactâ€”so remediation time is spent where it matters most.

Explore Attack Surface Testing

Stronger Privileged Access Controls

Reduce credential reuse and privilege sprawl that makes OT compromise fast and hard to contain.

Explore Assumed Breach

Audit-Ready Evidence

Translate technical results into defensible assurance artifacts for leadership and governance stakeholders.

Explore CIS Benchmark Audit

Verified Remediation

Retest critical fixes to confirm attacker paths are closed, not just patched on paper.
