Modern businesses are no longer confined to traditional office networks. Employees work remotely, applications are hosted in the cloud, and companies regularly collaborate with contractors, vendors, and third-party partners. As a result, traditional network security models are becoming less effective for protecting modern business environments.
Zero Trust Network Access (ZTNA) provides a modern approach to secure access. Instead of automatically trusting users once they connect to a corporate network, Zero Trust verifies users, devices, and access conditions before providing access to specific applications or resources.
ZTNA can help businesses reduce their attack surface, enforce least-privilege access, and provide secure connectivity for remote and hybrid employees. With many solutions available, choosing the right platform can be challenging.
Here are five Zero Trust Network Access solutions that modern businesses should consider.
1. Zscaler Private Access
Zscaler Private Access is a cloud-based Zero Trust Network Access solution designed for organizations that want to replace traditional VPN-based remote access.
Rather than connecting users directly to the corporate network, Zscaler Private Access creates secure connections between authorized users and specific applications. This application-focused approach can reduce unnecessary network exposure and limit the opportunity for unauthorized lateral movement.
The platform is designed to support employees, contractors, and other users who need access to private applications from different locations and devices.
One of its key advantages is scalability. Large organizations with distributed teams and complex IT environments can use centralized policies to manage access across different applications and locations.
Zscaler Private Access is particularly suitable for enterprises that want a comprehensive Zero Trust architecture and need to move away from traditional network-based remote access.
Best for: Large enterprises and organizations replacing traditional VPN infrastructure.
2. Cloudflare Access
Cloudflare Access is a Zero Trust Network Access solution designed to provide identity-based access to private applications and infrastructure.
The platform allows organizations to create access policies based on factors such as user identity, device posture, and authentication status. This allows businesses to control access at the application level instead of giving users broad access to an entire network.
Cloudflare Access can also work with different identity providers, making it easier for organizations to integrate Zero Trust access into their existing authentication environment.
Another advantage is its flexibility. Businesses can use it to protect web applications as well as other internal resources and infrastructure.
For organizations that want to gradually adopt Zero Trust without building a complicated network architecture, Cloudflare Access can be an attractive option.
Best for: Small and mid-sized businesses, distributed teams, and organizations looking for flexible cloud-based access security.
3. Palo Alto Networks Prisma Access
Prisma Access from Palo Alto Networks combines Zero Trust access capabilities with broader cloud-delivered security services.
The platform is designed to provide secure access for users regardless of where they are working. Organizations can apply centralized security policies while supporting employees who access applications from offices, homes, branch locations, and other environments.
One of the main benefits of Prisma Access is its ability to fit into a broader security strategy. Businesses that already use Palo Alto Networks security technologies may find it easier to integrate Prisma Access into their existing infrastructure.
The platform is also suitable for organizations looking to adopt Secure Access Service Edge (SASE) or Security Service Edge (SSE) approaches alongside Zero Trust Network Access.
With centralized management and extensive security capabilities, Prisma Access can support organizations with complex security requirements.
Best for: Enterprises that want ZTNA as part of a broader cloud security or SASE strategy.
4. Twingate
Twingate provides a software-based approach to secure remote access and is designed as an alternative to traditional VPN solutions.
Instead of giving users access to an entire network, Twingate allows organizations to control access to specific resources. This follows the Zero Trust principle of providing users with only the permissions they need.
The platform can be useful for businesses with remote or distributed teams because employees can securely access internal applications and infrastructure without relying on traditional VPN gateways.
Another benefit is its relatively straightforward deployment model. Organizations can introduce secure remote access without making major changes to their existing infrastructure.
Twingate can therefore be a practical option for smaller organizations that want to improve remote access security without adopting an overly complicated enterprise security platform.
Best for: Small and mid-sized businesses looking for a simple and modern VPN alternative.
5. Microsoft Entra Private Access
Microsoft Entra Private Access is Microsoft’s identity-focused Zero Trust Network Access solution.
It allows organizations to provide secure access to private applications hosted across on-premises environments and cloud infrastructure. Instead of relying on traditional network-level access, the platform uses identity and security policies to determine whether users should be allowed to access particular resources.
One of its biggest advantages is integration with the Microsoft ecosystem. Businesses already using Microsoft Entra ID, Microsoft 365, and other Microsoft security technologies may find it easier to incorporate Entra Private Access into their existing environment.
Organizations can also use conditional access policies to apply additional security requirements, such as multi-factor authentication and device-based conditions.
For businesses that already depend heavily on Microsoft’s identity and security infrastructure, Microsoft Entra Private Access can provide a natural path toward Zero Trust access.
Best for: Organizations heavily invested in Microsoft 365 and Microsoft security technologies.
Why Businesses Are Moving Beyond Traditional VPNs
Traditional VPNs were designed around the idea of creating a secure connection between a user and a private network. While VPNs can still provide secure connectivity, they may give authenticated users broader network access than they actually need.
Zero Trust Network Access takes a different approach.
Instead of assuming that an authenticated user should be trusted with network-wide access, ZTNA evaluates each access request and provides access to specific applications or resources based on predefined policies.
This approach can reduce the attack surface and make it more difficult for attackers to move between systems if an account or device becomes compromised.
ZTNA is especially valuable for organizations with remote employees, cloud applications, hybrid infrastructure, and third-party users.
Key Features to Look for in a ZTNA Solution
Businesses should evaluate several important capabilities when choosing a Zero Trust Network Access platform.
Identity-Based Access
The solution should be able to authenticate users and use their identity as an important factor in access decisions.
Multi-Factor Authentication
Multi-factor authentication adds another layer of protection beyond usernames and passwords and can help prevent unauthorized access when credentials are compromised.
Device Posture Checking
A strong ZTNA platform can evaluate whether a device meets the organization’s security requirements before allowing access to sensitive resources.
Least-Privilege Access
Users should receive only the access they need to perform their jobs. This can help reduce unnecessary exposure to internal applications and data.
Application-Level Segmentation
Instead of connecting users to an entire corporate network, ZTNA should provide access to specific applications and resources.
Identity Provider Integration
Integration with existing identity providers can simplify deployment and make it easier for IT teams to manage authentication and access policies.
Monitoring and Reporting
Visibility into user activity, access requests, devices, and security events can help IT and security teams identify suspicious behavior and improve security policies.
How to Choose the Right ZTNA Solution
The best Zero Trust Network Access solution depends on the organization’s size, infrastructure, security requirements, and existing technology stack.
Large enterprises may prefer Zscaler Private Access or Prisma Access because of their broad enterprise capabilities and scalability.
Organizations looking for a flexible and straightforward approach may consider Cloudflare Access or Twingate.
Businesses that already rely heavily on Microsoft technologies may find Microsoft Entra Private Access particularly suitable because it can integrate with their existing identity and security environment.
Before selecting a platform, organizations should evaluate deployment requirements, identity integrations, device security capabilities, application support, scalability, management tools, and overall security requirements.
It is also important to consider whether the organization needs standalone ZTNA or a broader SASE or SSE platform that includes additional security capabilities.
Final Thoughts
Zero Trust Network Access has become an important component of modern cybersecurity. As businesses adopt remote work, cloud applications, distributed infrastructure, and third-party collaboration, protecting access through a traditional network perimeter is becoming increasingly difficult.
Zscaler Private Access, Cloudflare Access, Palo Alto Networks Prisma Access, Twingate, and Microsoft Entra Private Access each offer different approaches to Zero Trust access.
The right choice ultimately depends on the organization’s specific requirements. Large enterprises may prioritize scalability and comprehensive security controls, while smaller businesses may prefer simpler deployment and management.
Rather than simply replacing a VPN, businesses should view ZTNA as part of a broader security strategy based on identity verification, least-privilege access, device security, and continuous policy enforcement.
With the right implementation, Zero Trust Network Access can help modern businesses provide secure and flexible access while reducing unnecessary network exposure.
