Operational Technology is all around us. All the products we buy, the food we consume, the energy we use, we all depend on it. In all these sectors, some of them are known as critical infrastructure, critical processes are managed through operational technology (OT) and information technology (IT) systems. Digital security of these systems is of increasing importance, as more and more OT systems are connected and controlled through IT systems. Moreover, cybercrime is growing: also in the world of critical infrastructure and last but not least nation states using cyber attacks for espionage or even to sabotage critical infrastructure.


Secura provides a broad range of services to assess, improve and verify the cyber resilience of our clients. We know that cyber-security within the industrial sector must be treated differently and understand the challenges that exist in both the IT and OT networks. To optimally serve our industrial customers we concentrated all our related expertise, knowledge, and experience in our Industrial market group. We are active in a variety of sectors: Energy & Utilities, Oil & Gas, Chemical Industry, Infra & Water, Food Production and Automotive. From a technical standpoint we cover the security for both the IT and OT Infrastructure. For IT this includes all on-premises and cloud systems and applications. For OT this includes all PLC’s, SCADA systems, DCS controllers, Safety systems, HMI’s and industrial applications. As we can cover both from the same team, we are able to focus on the interactions, dependencies and security permitters between IT and OT. We also provide a complete and holistic approach and look beyond just the technology, we therefor include the effect of people (awareness, knowledge, behavior) and (security) processes.


We offer multiple services that are tailored to the industrial sector and their specific requirements. First our advisory services, for example, gap-analysis or risk assessments based on IEC 62443, IT & OT Site assessments, Threat modelling, a NIS compliance check, and a security maturity review. All these services are designed to support our customers to identify risks and improve their security resilience, no matter their current security maturity state. We also offer offensive services in the form of penetration-tests and Red Teaming assignments, both in IT and OT environments. With these services we help our customers to validate their current security counter measures, test their defensive capabilities and discover possible unknown vulnerabilities. On top of these services, we also provide specific OT security training, offer a comprehensive IT/OT security awareness & behavior program, and perform OT security research. One notable example is the recent release of OTCAD, an Operational Technology Cyber Attack Database, that consists of a mapping between known OT-related cyber-attacks and MITRE’s ATT&CK framework for ICS.


Our clients rely on their IT and OT infrastructure to deliver their business processes safely and reliably while at the same time managing the great challenge of their cyber security risks. For all these challenges they can rely on Secura and our security services.
