OT Cybersecurity Services

In today’s increasingly interconnected industrial landscape, securing Operational Technology (OT) and Critical National Infrastructure (CNI) has become paramount.

When OT Meets IT: Efficiency Gains, Security Challenges

The convergence of OT, IIoT, and IT boosts efficiency but also expands the attack surface, exposing critical systems to sophisticated cyber threats. Guided by the Purdue Model, IEC62443 and best practices for ICS security, Systal’s comprehensive portfolio of services ensures robust protection at every layer of the architecture: from enterprise IT networks to field-level devices. Recognising the unique vulnerabilities and operational criticality of OT environments, Systal delivers tailored solutions to safeguard not only data but also the physical processes that underpin essential services, minimising risks to safety, productivity, and national security.

Our Solutions

Threat Detection and Response

Threat Detection: anomaly-based intrusion detection systems (IDS) tailored for SCADA, DCS, and PLC environments.

Managed Detection and Response: Managed services with expert Security analysts for rapid OT threat detection and response.

Network Security

Network Segmentation: micro-segmentation for IT, OT, and IIoT networks to limit lateral movement.

Firewall Solutions: industrial firewalls for real-time traffic inspection.

Secure Remote Access

Solutions for safe remote connections to OT and IIoT systems, including VPN replacements like ZTNA.

Real-time monitoring of remote sessions.

Risk and Vulnerability Management

Threat Modelling: identify, analyse, and prioritise potential security threats and vulnerabilities using different frameworks (STRIDE, MITRE ATTACK, etc) within OT environments to safeguard critical systems, processes, and data.

Asset Discovery and Inventory: identify and map all OT assets, including legacy devices.

Vulnerability Management: regular scanning and patch management for OT devices.

Access Management and Authentication

Identity and Access Management: centralise identify management and control over user and device access.

Adaptive Multifactor Authentication (AMFA): securing access to critical OT/IT systems by adding additional authentication factors depending on contextual information
and business rules.

Privileged Access Management: restricting admin-level access and just-in-time access to critical OT/IT systems.
