Zero Trust Network Access is a security access model in which users and services connect directly to defined applications rather than to the network. Unlike traditional VPNs, ZTNA does not provide network-level access or expose internal infrastructure.
ZTNA is based on the Zero Trust principle, where no request is trusted by default. The solution evaluates identity, device posture, connection context, and compliance with security policies before granting access.
Traditional VPN solutions create an excessive level of access by allowing users to connect to the internal network after successful authentication. In today’s environment of remote work, cloud services, and distributed teams, this significantly increases the attack surface.
ZTNA eliminates these risks by replacing network-level access with controlled access to individual applications. This approach minimizes lateral movement, reduces the impact of account compromise, and enables managed access without reliance on a traditional network perimeter.
VPN provides the user with access to the internal network after authentication. ZTNA provides access only to specific applications based on identity and policies.
VPN provides network access, which allows for lateral movement between resources. ZTNA conceals network infrastructure and isolates access to each application.
VPN trusts the connection after establishing a tunnel. ZTNA checks each access request considering context and risk.
VPNs are difficult to scale for cloud environments and remote work. ZTNA is initially designed for cloud, hybrid, and distributed environments.
The ZTNA access process begins with a request from a user or service to a specific application. The system verifies identity, connection context, and compliance with access policies. Only then is a secure connection to the specific resource established.
The user does not gain network-level access but only access to the permitted application. All actions are monitored and can be recorded for audit purposes. Access control is maintained throughout the session, and the level of access may change based on context.
Zero Trust Network Access is used to provide secure access for employees, partners, and contractors to internal and cloud applications. The solution is also suitable for secure access to administrative interfaces, business systems, and critical services.
ZTNA works effectively across corporate, hybrid, and cloud environments, providing a unified access model regardless of user location.
Zero Trust Network Access is critically important for enterprise organizations, the public sector, and critical infrastructure. The solution is also highly relevant for companies with remote teams, cloud environments, and advanced DevOps practices.
ZTNA in Zero Trust architecture
Zero Trust Network Access is a key element of the Zero Trust architecture, as it provides controlled access to corporate applications without exposing the network. In the Zero Trust model, there is no trust by default—each access request is verified regardless of the user’s or service’s location. The solution evaluates subject identity, connection context, and compliance with security policies before granting access.
ZTNA implements Zero Trust principles at the application access level, replacing traditional perimeter-based approaches. Access is provided without network exposure and without trust by default, in close integration with Identity & Access Management (IAM). Users and services are granted access only to explicitly permitted resources, reducing the attack surface and limiting unauthorized lateral movement within the infrastructure.
With ZTNA as part of a Zero Trust architecture, organizations can safely move away from VPNs, scale cloud and hybrid environments, and provide managed access to critical systems and data. This approach establishes a transparent and controlled access model that meets modern cybersecurity and digital transformation requirements.
