Zero trust networking operates on the principle that trust should never be automatically granted, regardless of whether a user, device, or application is inside or outside the network perimeter. Instead, it emphasizes strict verification and continuous validation of every entity attempting to access network resources.

Given the increasing sophistication of cyber threats, the need for zero trust network access (ZTNA) solutions has become paramount. These solutions empower organizations to adopt a comprehensive security posture, reducing the potential attack surface and enhancing threat detection and response capabilities.

This article will explore the top eight ZTNA solutions that are empowering organizations to fortify their defenses against cyberattacks in 2023.

Best overall

Cloudflare’s Zero Trust network solution offers a unified and flexible platform that simplifies setup and operations and guarantees a better end-user experience. The solution has a broad threat intelligence feature that protects against ransomware and phishing attacks by reducing users’ attack surface.

In order to ensure consistent and high-speed protection for all data, Cloudflare inspects all traffic in a single pass. Users can also obtain, activate, and authenticate every access request with FIDO-compliant security keys. This guarantees an extra layer of security as these keys cannot be intercepted or stolen by an attacker once they have been issued.

Key features of zero trust networking solutions

Any quality zero trust networking solution should include MFA, least privilege access, network segmentation, adaptive access controls, and threat intelligence integration.

Multi-factor authentication (MFA)

Zero trust networking solutions typically incorporate MFA, requiring users to provide multiple forms of verification, such as a password, biometric data, or a security token. This adds an extra layer of security by reducing the risk of unauthorized access, even if one factor is compromised.

Least privilege access

ZTNA solutions by nature enforce the principle of least privilege access, which means that users and devices are only granted the minimum level of access required to perform their specific tasks. This limits the potential damage that can be caused in the event of a compromised account or device.

Network segmentation

Segmentation — or, better yet, microsegmentation — involves dividing the network into smaller, isolated segments or zones. Each segment has its own security controls and policies, and access between segments is strictly controlled. ZTNA solutions implement this to prevent lateral movement of threats within any network and contain potential breaches.

Adaptive access controls

The adaptive access controls feature dynamically adjusts access privileges based on various factors such as user behavior, device posture, and contextual information. This ensures that access rights are continuously evaluated and adjusted to align with the current security posture and risk level.

Threat intelligence integration

ZTNA solutions often integrate with threat intelligence platforms and security tools to gather information about emerging threats, vulnerabilities, and known malicious entities. This integration helps identify and block suspicious activities or connections, enhancing the overall security posture.

How to choose the best zero trust networking solution for your business

Selecting the right ZTNA solution is a crucial decision that can significantly impact your organization’s security and productivity. With so many options available on the market, it’s essential to navigate through the choices effectively.

To help you make an informed decision, consider key factors like scalability and performance, ease of use and management, service and support, and ability to deal with security breaches.

Scalability and performance

It is important to choose a solution that can scale effectively to meet your organization’s needs. Consider solutions that offer flexible architecture capable of accommodating an increasing number of users, devices, and network segments without compromising performance. Ensure the software supports redundancy and high availability measures to minimize downtime and maintain continuous protection.

Ease of use and management

Assess the software’s user interface for intuitiveness and ease of navigation, as it will be crucial for administrators to configure and monitor the zero trust environment effectively. Look for software that provides a centralized management console or dashboard that allows administrators to define, update, and enforce policies easily. Check if the software offers automation features for policy enforcement, device onboarding, and security event response to streamline operations and reduce manual effort.

Service and support

Beyond the initial setup and implementation, it’s crucial to evaluate the level of service and support provided by the solution. Look for comprehensive customer service and support offerings, including access to knowledgeable support staff, training materials, active peer communities, and the possibility of dedicated account managers. 

Security breach performance

If your organization deals with sensitive data, it’s vital to assess how different companies have performed in major security breaches. Particularly, consider their ability to defend against DDoS attacks, which can severely impact network capabilities. Look for zero trust software solutions with a proven track record of effectively mitigating DDoS and other cyberattacks, providing you with the peace of mind that your data is safeguarded.
