NetNXT assesses your remote-access requirements, designs and implements a ZTNA platform that fits them, and manages it afterwards where that is part of the agreed scope. Access is granted per application and per user rather than to the whole network, for employees, contractors and third parties alike.

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. These are the six points where that usually breaks down.
A VPN places the user on the network, so reaching one system usually means reaching far more than that.
Users accumulate more permissions than their role needs, and those permissions are rarely reviewed.
Applications published for remote access sit on the public internet, where they can be found and probed.
Backhauling traffic through a central concentrator adds latency and drops, particularly for cloud applications.
Network-level controls are a blunt instrument for expressing who should reach which application, and when.
Third parties are issued the same broad credentials as staff, with limited ability to time-bound or audit them.
Zero Trust Network Access gives users access only to approved applications, not the full network. Unlike a VPN, it verifies identity, device posture, role and context before allowing access.
NetNXT designs, implements and manages ZTNA solutions that enforce identity-based, least-privilege access across remote users, third parties, cloud applications and on-premises applications.
Users connect directly to approved applications rather than to the network. The rest of your infrastructure stays unreachable.
Applications are not published to the internet, removing the attack surface threat actors rely on to gain a foothold.
Access is granted on verified identity, role and real-time context, and re-verified rather than assumed to still hold.
Centralised monitoring of every access event: who accessed what, from where, on which device and when.
If a device is compromised, microsegmentation contains it. There is no flat network for an attacker to traverse.
Vendors and contractors get time-limited, controlled access to specific applications, without VPN credentials or network access.
Cloud-native routing sends traffic to the nearest edge instead of backhauling it through a central VPN concentrator.
Consistent, enforced access policies across cloud, SaaS and on-premises applications, without managing separate systems.
Stronger security, tighter access control and simpler remote connectivity. What that is worth depends on your estate, which is why the two headline effects below are stated with their conditions rather than as figures.
Applications stay off the public internet, with no exposed ports or network ranges. How far this reduces exposure depends on how much of your estate moves behind ZTNA.
Retiring VPN concentrators removes their hardware, licensing and maintenance. Any saving depends on your existing contracts, licensing and the platform chosen.
Implicit trust is removed, least-privilege is enforced per application, and the blast radius of a compromise is smaller.
Employees, vendors and partners reach business applications from any location and device under one policy model.
Access without VPN latency, dropped connections or client issues, which reduces the support load that comes with them.
A central console for user access, policies and activity, in place of several separate access tools.
Audit logs, monitoring and policy enforcement that support ISO, RBI, GDPR and SOC 2 evidence requirements.
New users and applications are onboarded through policy rather than through network changes and lead times.
See how organisations apply zero trust network access in the situations where VPNs usually struggle.
Give remote and hybrid workers access to corporate applications without exposing your network or relying on VPN infrastructure that cannot scale.
Capabilities that cover identity, edge, cloud and on-premises access in one policy model.
Verify user identity through multi-factor authentication, with integration into existing identity providers such as Active Directory, Okta and Entra ID for policy-driven access control.
Isolated segments that contain applications and data, so a compromise in one place does not become access to everything else.
Access decisions that account for device posture, location, time and behaviour, and that can tighten when the context looks wrong.
Direct user-to-application connectivity with no network exposure, covering cloud-native, SaaS and legacy on-premises applications.
Traffic is routed through a global edge network rather than backhauled to a central concentrator, which shortens the path between the user and the application.
A cloud-delivered platform without appliance dependencies, so capacity and updates are handled by the platform rather than by your team.

ZTNA grants access to individual applications rather than to the network they sit on. Each request is checked against the user's identity, their device and the policy for that application, so someone who is allowed to reach one system does not thereby reach everything else on the same network.
A VPN usually places the user on the network and relies on internal controls to limit what they reach from there. ZTNA connects the user to named applications only, and keeps those applications off the public internet. The practical differences are the breadth of access granted, how much of the estate is exposed, and how much per-application policy you can apply.
Often, but not always. Most user-to-application access moves across well. Cases that need care include legacy protocols, applications that expect a routed network path, administrative access to infrastructure, and site-to-site connectivity. We assess which of your applications and user groups can move, and what remains on an existing path or needs another approach.
Yes, and third-party access is one of the clearer cases for it. Rather than issuing VPN credentials that carry network access, a contractor or vendor is given access to the specific applications they need, for as long as they need it, with that access logged and revocable on its own.
Typically: reviewing your access requirements and current remote-access setup, selecting and designing the platform, integrating it with your identity provider, defining application and user access policies, planning the migration from VPN, piloting with a limited group, then rolling out in phases. The exact scope is agreed per engagement and depends on the platform and the environment.
ZTNA platforms are built to sit alongside an existing identity provider and to send logs to monitoring tools, and most support single sign-on, multi-factor authentication and device posture signals. Which integrations are available, and how deep they go, varies by platform, so we confirm this against your identity and security stack during assessment.
Yes, where ongoing management is part of the agreed scope. That can cover policy changes, onboarding new applications and users, reviewing access, and working with your team on operational issues. What is included is set out in the service agreement rather than assumed.
In phases rather than as a cutover. We start by mapping which users need which applications, agree an order based on risk and disruption, pilot with a small group to validate the policies and integrations, then move the remaining applications and users in stages. VPN access is usually retired progressively as each group moves.
Understand whether your current remote-access model meets your organisation's security and access requirements. NetNXT can help assess your VPN environment, identity integrations, application access needs and migration priorities, then outline practical next steps.
