ZTNA (Zero Trust Network Access) is a security model that gives users access to applications only after verifying their identity, device posture, and other context. It does not automatically trust anyone inside or outside the network. Every request is checked as if it comes from an open, untrusted network.
How ZTNA Works
Unlike traditional VPNs that grant broad access once a user connects, ZTNA restricts access to only the applications or services the user is authorized to use. It uses identity-based policies, device validation, and real-time risk assessment to control access.
ZTNA operates on the principle of “never trust, always verify.” It assumes that threats could come from inside or outside the network. So it verifies every session and enforces least-privilege access. Users do not see the entire network, only what they are allowed to access.
Why Indian Enterprises Are Adopting It
As remote work, cloud adoption, and hybrid IT become the new normal, traditional perimeter-based security no longer works. Indian companies in BFSI, IT, pharma, and manufacturing are adopting ZTNA to replace or augment their VPNs.
It helps reduce attack surfaces, prevent lateral movement, and comply with data security regulations. Many are using ZTNA as part of a broader Secure Access Service Edge (SASE) architecture to unify security and access control across users and locations.
What Proactive Offers
ZTNA needs more than a product. It requires clear access policies, integration with identity providers, and visibility into users, devices, and applications. Proactive helps design and implement ZTNA that works with your existing infrastructure.
We offer ZTNA through leading platforms like Cisco Duo and Cisco Secure Access, and ensure it is deployed in a way that improves both security and user experience. Whether you want to roll it out for remote users or across the enterprise, we provide planning, deployment, and ongoing support.
Final Word
ZTNA is not just a security upgrade. It is a new way of thinking about access in a world where users and data are everywhere. Proactive can help you design a ZTNA model that matches your business needs and scales with your growth.
