OT & IoT Security Assessment

Securing your OT and IoT landscape with Innovation and Vigilance

Industry Challenges

Disparate OT/IT Security

Lack of collaboration between Operational Technology (OT) and Information Technology (IT) security creates vulnerabilities in converged environments.

IT/OT Integration & Cyber Threats

Integrating IT and OT systems improves efficiency but increases the attack surface for Zero-Day threats and other malicious actors.

IoT Threat Landscape

The proliferation of Internet of Things (IoT) devices in OT networks creates a larger pool of potential targets for hackers to build botnets and launch Distributed Denial-of-Service (DDoS) attacks.

OT Network Complexity

As OT systems evolve and new technologies are integrated, the original network architecture can become complex and difficult to monitor for vulnerabilities using Security Information and Event Management (SIEM) tools.

Legacy OT Systems

Legacy OT systems, often with outdated security protocols, are prime targets for attackers exploiting known vulnerabilities.

Inconsistent Security

Inconsistent security practices and a lack of standardized security protocols like Zero Trust across OT and IoT systems create vulnerabilities for attackers.
