Next-Generation Network Access Control for India’s Leading Commodity Exchange

Operating in one of India’s most regulated financial environments, the country’s largest commodity derivatives exchange required a stronger framework for controlling network access, validating endpoint compliance, and reducing security risks across its critical trading infrastructure. Swan Solutions & Services implemented an enterprise-grade Network Access Control (NAC) solution using Aruba ClearPass, enabling centralized policy enforcement, device profiling, posture assessment, and secure authentication for employees, contractors, and guests. The deployment helped establish a unified security layer across wired, wireless, and VPN environments while improving visibility into every device connecting to the network.

To ensure uninterrupted operations, the solution was architected with a resilient Data Center and Disaster Recovery (DC/DR) design featuring clustered Aruba ClearPass appliances, Active Directory integration, and redundant RADIUS authentication services. This high-availability architecture provided consistent access control, streamlined administration, and reduced the complexity of managing multiple security systems. By leveraging Swan’s expertise in Networking and Cyber Security Solutions, the organization gained a scalable foundation capable of supporting future growth while maintaining strict governance requirements.

The implementation significantly strengthened the exchange’s security posture by enforcing role-based and device-based access controls, ensuring that only authenticated and compliant endpoints could access network resources. The organization benefited from improved network visibility, simplified policy management, enhanced business continuity, and stronger alignment with regulatory and audit requirements. This successful deployment demonstrates how Swan Solutions helps BFSI enterprises modernize access security while ensuring resilience, compliance, and operational efficiency.
