SOLUTION OVERVIEW

Tenable.ot for Owl Cyber Defense

Business Challenge
Industrial control systems (ICS) are the bedrock of manufacturing processes andcritical infrastructure. However, the convergence of your IT and OT environments
contributes to an increased attack surface and potential attack vectors. What you
once physically air-gapped, now requires technology solutions to view and manage
IT and OT activity and threats without creating new ones.
As such, one of the major challenges organizations face is how to safely andseamlessly gain visibility and move data from your OT environment to your IT
infrastructure without introducing any new threats.

Solution
Tenable.ot protects industrial networks from cyber threats, malicious insiders
and human error.
From threat detection and mitigation to asset tracking, vulnerability
management, configuration control and patented active querying technology,
Tenable.ot’s ICS security capabilities maximize the safety and reliability ofyour operational and critical infrastructure environments. Tenable.ot delivers
comprehensive situational awareness across all sites and respective OT assets.
Owl Cyber Defense is a leader in data diode and cross-domain networkcybersecurity. Owl develops market-first, one-way data transfer products tomeet a variety of operational needs, from entry-level to enterprise.

Technology Components• Tenable.ot• Owl DiOTa or DIN-Rail data diodewith Talon proprietary software

The Challenge• IT and OT convergence increases
your attack surface and attack vectors• Achieving a comprehensive viewin a single pane of glass• Legacy OT systems are notarchitected with built-in security• Increased network complexity anddistribution makes environmental
security and control difficult• Increased targeting of manufacturing
and critical infrastructure

Key Benefits

With today’s emerging threats, you need full visibility, security and control
between your IT and OT environments, and where appropriate, you need toseparate your OT network from your IT network. In such cases, Owl diode canprovide the necessary separation with accessibility to your IT/OT environments.

• The joint solution enables visibility ofcritical OT assets that were previously
air-gapped from IT without introducing
risk of lateral threats

Tenable and Owl work together to pass needed data while ensuring diode-based
air-gaps between networks. A Tenable.ot sensor is located on the critical/OT
network and forwards captured traffic to Tenable.ot, which resides outside of yourOT network. Owl separates the two networks, but sensor to ISP traffic can securely
pass through it.

• Tenable.ot’s data seamlessly flows
through the Owl diodeWith this tested and proven joint solution, you can trust that your internal andcritical networks are physically inaccessible from your external network while
Tenable.it monitors your sensitive network for full security, visibility and control.

• Data diode stops threats that are detected• The integrated solution makes it easy
to configure and deploy network sensors
in segments protected by the Owl diode• Advanced 360-degree visibility solutiondelivers both IT and OT updates tosecurity systems in isolated networks
