What is a Zero Trust Network Access (ZTNA) Solution?

A ZTNA (Zero Trust Network Access) is a network access solution that provides secure access to corporate resources, applications, and data based on strict identity verification. ZTNA stands out from the traditional network access methods by following an "Always Verify, Never Trust" principle. This makes it ideal for enabling secure remote work and protecting sensitive data.

Why Do Businesses Need a Zero Trust Network Access (ZTNA) Solution?

Cyber attacks are rampant, with one happening every 39 seconds¹ and over 50% of businesses² lacking visibility into unsecured WiFi on employee devices (BYOD). That’s not all; 80% of all breaches³ use compromised identities. Traditional security isn’t enough to safeguard against the latest cyber threats.

ZTNA offers a modern solution to security threats by isolating application access from the network. This protects your data even on compromised devices and ensures that only authorized users get access to specific applications.

How Zero Trust Network Access (ZTNA) is Different from Legacy Virtual Private Networks (VPNs)

Choosing between Zero Trust Network Access (ZTNA) and legacy Virtual Private Networks (VPNs) is critical for ensuring your network’s security, scalability, and performance. Legacy VPNs, designed before the widespread adoption of cloud applications and remote work, struggle to meet the needs of modern organizations. Traditional VPNs fall short on security and privacy with their outdated encryption and user authentication methods.

Here’s a comparison of how ZTNA and VPNs differ in key areas:

ZTNA vs VPN: Security

ZTNA grants access based on the 'Know to Access' philosophy. This means that only authorized users and devices are explicitly identified and authenticated before being granted access to resources each time. In contrast, a VPN authenticates only once at the start of the connection. This can be problematic because it potentially exposes the network to insider threats once that initial trust is established.

ZTNA vs VPN: Access Control

ZTNA restricts access to only the applications or data required, significantly reducing the attack surface. VPNs, on the other hand, grant users broad access to all corporate resources once authenticated. This can result in users having more access than necessary, posing a potential risk for compliance violations.

ZTNA vs VPN: Traffic Management

ZTNA routes only the necessary internet traffic through the tunnel, reducing wait times. In contrast, VPNs route all traffic through the corporate network, creating bottlenecks that can lead to delays and disruptions for users accessing both internal resources and external websites.

ZTNA vs VPN: Scalability

ZTNA is a cloud-based and hardware-free solution, making scalability easier as needed. Traditional VPN comes with security stacks that require expensive investments and complex management making it difficult to scale up.

What are the benefits of Zero Trust Network?

Enhanced Security

ZTNA creates a secure and encrypted tunnel for network access and data transmission, preventing unauthorized access and malicious actors.

Authenticated Access

ZTNA ensures that every time access to your network is granted only to authorized devices and applications with proper security configurations, minimizing the risk of breaches each time.

Reduced Attack Surface Area

ZTNA grants access only to the required applications or data based on the configured policies, thereby reducing the attack surface in case of insider threats.

Secure BYOD Access

ZTNA ensures that personal devices accessing corporate resources adhere to security requirements through the inbuilt Zero Trust Architecture.

Work from Anywhere

ZTNA allows remote employees to access corporate resources securely from any part of the world and at any time.

Data Breach Mitigation

Internet traffic is securely tunneled through the ZTNA tunnel, eliminating the risks of data breaches and unauthorized access.

FAQs

What is VPN?

Virtual Private Networks, or VPNs, mask your IP address, hiding your location and unlocking geographically restricted content. They also offer basic encryption for your online communications.

What is Zero Trust Network?

A Zero Trust Network model is based on establishing trust through authentication, authorization, and continuous validation of each network access attempt to corporate resources. It works on the principle of not trusting any access attempt by default.

What are the differences between VPN and ZTNA solutions?

Legacy VPNs follow a one-time validation approach. Once inside the organization's network (the castle), everything is trusted and granted wide-reaching access to a company's sensitive files. In the Zero Trust Network, everyone and everything that tries to access resources (like data or applications) needs to be verified every single time. This makes it even more difficult for attackers to gain access to sensitive information, even if they break through the initial defenses.

What are the three key principles of the Zero Trust Architecture?

The three key principles of Zero Trust Architecture are continuous verification of devices and users, granting least privilege access to resources, and minimizing breach impact.

How does ZTNA works?

ZTNA continuously evaluates users, devices, and applications to ensure they meet specific security policies before granting access. Access is granted based on identity, context (such as location, device health, and behavior), and the specific resource being requested. Only authenticated and authorized users can access the appropriate resources.
