Securing what keeps the world running
OT Security Consulting
IT/OT convergence has become increasingly important for improving the efficiency and safety of industrial operations. However, this digital overlap has also introduced new cyber security risks, interoperability issues, and data management challenges, as legacy systems and interconnected OT systems are exposed to complex new networks.
Protecting the systems that power your business
OT security consultancy from Littlefish Group is precisely tailored for industrial environments and designed to help your organisation modernise by facilitating the integration of IT and OT systems, evaluating security controls, and ensuring the protection of critical assets.
Our cyber professionals recognise the critical importance of OT security, especially in light of stringent regulatory compliance requirements such as NIS2, HSE (COMAH-OG 0086), and NIS-NCSC CAF. Our expertise lies in seamlessly mapping these regulations to industry-leading OT standards like ISA/IEC 62443 and NIST 800/82, ensuring comprehensive protection and compliance for your operational technology environments.
Increase reliability and protect your productivity
Boosting cyber security resiliency for OT is an essential proactive strategy to help safeguard critical assets, operations, and the overall business success of the organisation in question – not to mention, OT is fundamental for maintaining the infrastructure that underpins most modern industrialised societies.
That’s why, with Littlefish Group’s cyber security consultants by your side, the choice is never between being productive and being secure. Our OT security consultancy service is designed to carefully review and continuously improve the cyber hygiene of your OT environment, along with implementing best practice guidance aligned with ISA/IEC 62443 and support to remote access solutions.
