The Problem

Legacy VPN and Remote Access Challenges Enterprises Face

Traditional VPNs give users broad network access, increase attack surface, and make it harder to enforce least-privilege security across remote users, vendors, and cloud applications.

VPN Grants Too Much Network Access

VPN grants network-wide access instead of application-only

Over-Privileged Access

Users have more permissions than needed

Exposed Applications

Increased attack surface from exposed apps

Slow and Unreliable VPN Experience

Frustrating user experience on legacy VPN

Least-Privilege Gaps

Difficulty enforcing least-privilege policies

Uncontrolled Vendor and Contractor Access

Securing remote users & third parties is complex

THE SHIFT

How Does ZTNA Replace VPN Based Access

Zero Trust Network Access is a security model that gives users access only to approved applications, not the full network. Unlike VPN, ZTNA verifies identity, device posture, role, and context before allowing access.

TRADITIONAL VPNLEGACY

Broad Network Access

  • Broad network access increases attack surface
  • Poor performance for cloud applications
  • Complex to scale and manage
  • Limited visibility into user activity
  • Enables lateral movement after breach
ZTNA APPROACHMODERN

Application-Level Access

  • Application-level access reduces exposure
  • Optimized performance for cloud and SaaS
  • Cloud-native scalability and management
  • Complete visibility and analytics
  • Microsegmentation prevents lateral movement
THE SOLUTION

How NetNXT ZTNA Service Secure Enterprise Application Access

NetNXT designs, implements, and manages ZTNA solutions that enforce identity-based, least-privilege access across remote users, third parties, cloud apps, and on-prem applications.

01

Application-Only Access

Users connect directly to approved applications—not the network. Your infrastructure remains invisible and protected at all times.

02

Zero Network Exposure

Applications remain completely hidden from the internet, eliminating the attack surface threat actors rely on to gain a foothold.

03

Least-Privilege Enforcement

Access is granted strictly based on verified identity, role, and real-time context. Nothing more. Continuously re-verified.

04

Complete Visibility

Centralized monitoring of every access event—who accessed what, from where, on which device, and when—in real time.

05

Prevents Lateral Movement

Even if a device is compromised, microsegmentation contains the breach. Attackers cannot traverse your network.

06

Secure Third-Party Access

Vendors and contractors get time-limited, controlled access to specific applications—without VPN credentials or network access.

07

Better Performance

Cloud-native, globally optimized routing delivers faster and more reliable access than any VPN architecture can match.

08

Unified Across Environments

Consistent, enforced security policies across cloud, SaaS, and on-premises applications—without managing separate systems.
