Barracuda ZTNA - Secure access and zero trust for your network

Written by Cloud · Systems · Networking | Aug 6, 2025 6:37:00 AM

The exponential growth of remote work, the proliferation of unmanaged devices, and the accelerated adoption of cloud environments have completely transformed the paradigm of access to corporate resources. In this scenario, traditional perimeter-based approaches are no longer effective. While widely used, VPNs have security, visibility, and scalability limitations that make them insufficient in the face of today's threat level.

Today, more than ever, the Zero Trust strategy is positioned as the most robust answer to protecting distributed environments. Instead of relying on user or device location, Zero Trust is based on a clear premise: "never trust, always verify".

In this context, Barracuda ZTNA emerges as an advanced solution to implement secure and controlled access to applications and services, both in the cloud and on-premise environments.

What is Barracuda ZTNA, and why is it relevant now?

Barracuda ZTNA (Zero Trust Network Access) is a cloud-based secure access platform that enables organizations to protect access to their critical resources without relying on private networks. It replaces traditional VPNs with a granular, more secure approach that is more aligned with today's realities.

Based on the principles of the Zero Trust model, Barracuda ZTNA:

Continuously verifies the identity

User and device identity

Applies micro-segmentation

Granting access only to the necessary applications.

Integrates with identity management solutions

(IAM), MDM and access control systems

Allows remote access to applications

Without directly exposing the network

This approach significantly reduces the risk of lateral movement by insider threats or external actors gaining access to the network.

Cloud-first architecture with granular control and continuous authentication

Unlike traditional VPNs, which establish a permanent, generalist tunnel to the corporate network, Barracuda ZTNA uses a cloud-native architecture that segments access by application, user, and context.

Key differentiating capabilities:

  • Continuous and contextual authentication, integrated with services such as Azure AD, Okta or Google Workspace.
  • Lightweight agents in managed devices and agentless access option (clientless) for browsers.
  • Micro-segmentation to prevent unauthorized access between applications.
  • Integration with Private Cloud, Data Center and SaaS, enabling a unified experience.
  • Detailed monitoring of access, usage and behavioral analysis.
