Operational technology was built for availability and safety, not to withstand today’s cyber threats. As control systems connect to wider networks, remote operations and new customer-facing services, securing them requires a structured, standards-aligned approach across the full security lifecycle – from initial threat assessment through to ongoing compliance.
L2iQ applies this framework to protect mission-critical OT systems in every sector, aligned to IEC 62443 and the regulatory frameworks that apply to your industry. L2iQ is a Transport for NSW Technically Assured Organisation (TAO) for Cybersecurity.
IEC 62443 risk assessments, risk registers and treatment plans
Compliance evidence packages for regulatory frameworks such as the Australian Energy Sector Cyber Security Framework (AESCSF)
Secure architecture design, including secure remote access and remote control
Identity and access management, privileged access management, MFA and network access control
OT network monitoring and threat detection, integrated with SIEM and security operations centres
Security testing, operational procedures and incident response plans
Remediation programmes with clear closure criteria, supporting evidence, and independent assurance
We also design and cost security operations for the long term, with full CAPEX and OPEX lifecycle estimates for monitoring technology and services. The outcome is risk reduction that is genuinely achieved and verifiable – not just documented.
