Without knowing what exists in your environment, it’s impossible to manage—or secure—it effectively. That’s where visibility into your organization’s Operational Technology (OT) network becomes foundational.

Much like the SANS Five Critical Controls for ICS, the National Institute of Standards and Technology (NIST) developed the Cybersecurity Framework (CSF) to help organizations build resilient, risk-based cybersecurity programs. While the NIST CSF was created for U.S. government agencies, it has become one of the most widely adopted frameworks across industries—and for good reason. Its principles apply just as strongly to private enterprises, especially those operating complex OT environments.

Start With “Identify”

The first pillar of the NIST CSF is Identify—the requirement to understand your assets, systems, and vulnerabilities. In OT environments, this step is often the most challenging and the most overlooked.

Complete asset visibility across OT networks enables organizations to:

• Understand what systems are in place and how they communicate

• Identify risks and exposures tied to legacy devices and unmanaged assets

• Make the remaining CSF functions—Protect, Detect, Respond, and Recover—more effective and actionable

Without this foundational visibility, even the strongest security controls are operating with blind spots.

Gaining OT Visibility Without Disruption

Surya Technologies is powered by Claroty, the leader in OT and IoT security. For organizations that lack comprehensive asset visibility, we often recommend starting with Claroty Edge.

Claroty Edge provides a rapid, non-intrusive way to gain insight into your OT environment—without requiring network changes, physical sensors, or deployments at lower Purdue levels. In less than 10 minutes, organizations receive:

• A detailed inventory of OT assets

• An exposure score highlighting risk areas

• Immediate insight to inform next steps

For organizations ready to go further, the Claroty Platform delivers deep, continuous visibility across Cyber-Physical Systems (CPS), including OT and IoT assets such as PLCs, HMIs, RTUs, security cameras, card-access systems, and more. Beyond visibility, the platform enables exposure management, secure remote access, and threat detection—bringing asset awareness, risk reduction, and protection into a single solution.

Final Thoughts

Surya Technologies meets organizations wherever they are on their OT security journey. We operate as an extension of your existing security team, co-managing the Claroty Platform to deliver complete visibility, protection, and operational support across IT and OT environments.

Our managed services include:

• 24/7 Help Desk, NOC, and SOC coverage for IT and OT

• Secure endpoint, identity, Microsoft 365, and cloud environments

• Monitored and protected factory networks, PLCs, and HMIs

By starting with visibility and aligning to proven frameworks like NIST, organizations can move from reactive risk management to a proactive, resilient OT security posture.
