Operational Technology Services

Visibily’s advisory services leverage industrial control systems (ICS) experts with a cybersecurity focus to blend the best security programs with existing control services. Our primary objective is to maintain the health and safety of your OT environments and keep your facilities online. Visibily offers a hardening service, which is the foundation for identifying risk and qualifying opportunities, alongside additional services to fit your unique requirements.

Core Advisory Service

• Security Risk Assessment: This tabletop evaluation uses a process hazard analysis to identify cyber risks related to the impacts and consequences of a cyber disruption to client operations.
• Threat Modeling: Utilizing the results of the risk assessment, this service catalogs threat actors, cyber consequences, and malicious activity to identify potential threats.
• Strategic OT Roadmap: This engagement tailors a roadmap of future projects to your unique objectives based on cost, complexity, and effectiveness.

Additional Advisory Services

• OT Technical Network Validation: We employ a best-in-class OT asset discovery and inventory tool to evaluate your network’s cyber risk and identify technical areas for improvement.
• OT Site Walk: Our OT cyber experts conduct on-site evaluations of your facilities, focusing on physical sites and third-party risks to your OT assets.
• OT Policy Build: We facilitate client discussions to define, design, and implement your OT security policies to mitigate risk in your environments.

Visibily’s deployment services provide organizations with the tools and services necessary to gain insights and control over the protection of your process control systems, SCADA systems, and connected devices.

Core Tech Deployment Services

• OT Tech Rack and Stack: Quickly scale your installation resources and reduce your deployment timeline with installed OT tools by Visibily experts tailored to your needs and budget. Our experts possess the skills to install physical hardware in remote and hazardous environments across global sites, ensuring your installation projects stay on schedule.
• Tuning and Integration: Enhance your alerting system by surfacing the right alerts to analysts based on your preferences, reducing false alerts and network noise. Visibily integrates tool telemetry into your SIEM/SOAR/SOC or Visibily MXDR platform, providing you with a new level of visibility and control over your OT environment and devices. We support vendors specializing in OT security that align with your use cases and strategies, including Armis, Claroty, Dragos, Forescout (Silent Defense), Microsoft (Azure Defender for IoT), Nozomi, Palo Alto Networks (Palo Alto IoT), and Tenable (Tenable.ot).

Additional Deployment Services

Visibily provides your team with the appropriate next steps for critical scenarios, including OT condition violations, malware/ransomware incidents, reconnaissance, internet violations, new device detections, and environments that cannot be reached.

Visibily offers a full suite of managed security services designed to alleviate the operational burden on your teams while bringing deep OT expertise into your organization.
