For long, virtual private networks (VPNs) were the answer for secured access for remote working users. With the ongoing global shift to remote working, organizations can no longer simply depend on VPNs to manage their confidential data. For instance, VPNs do not enable granular control, thus increasing the vulnerability to data breaches, compromised credentials, and insider threats.
The Limitations of VPNs
- Overly Permissive Access - VPNs often grant access to entire network segments
- Poor User Experience - Backhauling traffic causes latency and performance issues
- Complex Management - Multiple VPN concentrators are difficult to maintain
- Security Gaps - Once inside, lateral movement is unrestricted
- Third-Party Risk - Contractors and vendors get excessive access
How ZTNA Works
Zero Trust Network Access provides application-level access based on identity and context:
- User authenticates through identity provider
- Device posture is verified
- Context (location, time, risk) is evaluated
- Access is granted to specific application only
- Continuous verification throughout the session
Benefits of ZTNA
- Reduced attack surface with application-level access
- Improved user experience with direct-to-cloud connectivity
- Granular access control based on identity and context
- Better visibility into user and application behavior
- Simplified management through cloud-delivered service
ZTNA for Third-Party Access
ZTNA is particularly valuable for securing third-party access:
- Contractors get access only to specific applications they need
- Access can be time-limited and easily revoked
- All activity is logged for audit purposes
- No network-level access reduces risk exposure
Conclusion
ZTNA represents the future of secure remote access. By replacing outdated VPNs with identity-centric, application-level access, organizations can better protect their resources while improving user experience.
