Support Solution for Fortinet SSL CVE-2023-27997

Fortinet Security Patch VulnerabilityIntroduction to Fortinet CVE-2023-27997 underlying problem:

Virtual Private Networks (VPNs) have long been a reliable solution for secure remote access. However, recent security vulnerabilities, such as the undisclosed critical remote code execution flaw in Fortinet's SSL VPN devices (CVE-2023-27997), have highlighted the need for a more robust and future-proof approach. Fortinet is not alone, many other VPN vendors have faced security issues as the underlying security infrastructure used by VPNs is aging and is more vulnerable to attack than a modern solution such as the fast ZTNA from Cloudbrink.

As Gartner predicts the replacement of VPN technology by Zero Trust Network Access (ZTNA) by 2025, it is essential to explore fast ZTNA solutions like Cloudbrink. In this blog, we discuss why Cloudbrink's high-performance ZTNA is the best way forward for Fortinet and other legacy VPN users.

The Rise of ZTNA and Its Advantages:

ZTNA represents a paradigm shift in secure access, focusing on the principle of "never trust, always verify." This approach ensures that users and devices are continuously authenticated and authorized before accessing network resources, significantly reducing the attack surface and mitigating potential security breaches. Cloudbrink's ZTNA offers several advantages over legacy VPNs, including:

1. Enhanced Security:

Recent security incidents, such as the critical vulnerability in Fortinet's SSL VPN devices, highlight the need for a stronger security posture. Cloudbrink's ZTNA adopts a comprehensive zero-trust architecture, providing granular access controls, multi-factor authentication, deny-all firewall, automated moving target defense (AMTD), and continuous monitoring. By eliminating trust assumptions and constantly moving the attack target, Cloudbrink ensures that only authorized users and devices can access specific resources, and attackers have less to attack. This significantly reduces the risk of data breaches.

2. Unparalleled Performance:

Cloudbrink's high-performance ZTNA solution sets it apart from other secure access solutions available today. It delivers exceptional speed and responsiveness, offering up to 30 times faster performance compared to traditional VPNs and other ZTNA solutions. With Cloudbrink, users experience seamless connectivity and swift access to applications, boosting productivity and job satisfaction across the organization.

3. Simplified Management:

Managing a complex VPN infrastructure can be time-consuming and resource-intensive. Cloudbrink's software-only service simplifies the management process by providing a centralized console for policy enforcement, access control, and user management. Administrators can efficiently control access rights, monitor user activity, and respond swiftly to emerging security threats, saving valuable time and resources.

4. Scalability and Flexibility:

As organizations grow and adopt hybrid or multi-cloud architectures, scalability becomes crucial. Cloudbrink's ZTNA offers flexibility and scalability, accommodating dynamic network environments and ensuring seamless connectivity across distributed locations. It easily scales to meet evolving business needs, whether expanding geographically or integrating with new cloud services. Unlike VPN solutions that add contention and slow down access when adding new users, Cloudbrink’s service scales up without impacting individual user performance.

5. Seamless Transition and Cost Efficiency

Migrating from legacy VPNs to ZTNA may seem challenging, but Cloudbrink provides a smooth transition path. Its compatibility with existing infrastructure and seamless integration capabilities minimize disruption and associated costs. Furthermore, Cloudbrink's flexible pricing options enable organizations to optimize costs based on actual usage and scale, eliminating unnecessary expenses.


The recent Fortinet SSL VPN vulnerability underscores the need for a secure access solution that offers robust protection and exceptional performance. As Gartner predicts the replacement of VPNs by ZTNA, Cloudbrink's high-performance ZTNA with AMTD emerges as the ideal choice for Fortinet and other legacy VPN users. With enhanced security, unparalleled performance, simplified management, scalability, and seamless transition, Cloudbrink empowers organizations to embrace the future of secure access.

Make the shift from legacy VPNs to Cloudbrink's high-performance ZTNA today, and unlock a new level of secure, efficient, and future-proof connectivity.
