IT & OT Security Assessment | Zettawise Consulting Services

The Approach and Methodology

Vulnerability Assessment & Penetration Test (VAPT)

In today’s converged enterprise landscape, the boundaries between IT and Operational Technology (OT) are increasingly blurred—making security risks more complex and consequences more critical. Zettawise’s IT/OT VAPT service is designed to uncover vulnerabilities across both digital and industrial environments, helping organizations proactively defend against evolving cyber threats.

Our approach goes beyond surface-level scans. We simulate real-world attack scenarios to evaluate your infrastructure’s resilience—from enterprise networks and cloud assets to SCADA systems, PLCs, and industrial control protocols. Whether it's a misconfigured firewall or an exposed HMI interface, we identify weaknesses before adversaries do.

Security, Agility, Speed

We have adopted the following testing approach for the same

Whitebox Testing

Credential Testing.
Full visibility into the inner workings of the asset.
Sharing full network and system information.
Simulates a targeted attack on a specific system.

Greybox Testing

Blackbox testing + Credentialed testing.
Limited information is shared with the tester.
Simulate either an insider threat or an attack that has breached the network perimeter.

Blackbox Testing

Zero visibility into the asset's functions and workflows.
No knowledge of the codebase or infrastructure.
Most authentic as tester demonstrates how an adversary with no inside knowledge would target.

Use Cases

Securing a Nation’s Digital Borders
