Featured Reviews

Ciyagi Ciyagi - PeerSpot reviewer
Senior Solution Architect & Delivery Lead at a tech services company with 10,001+ employees
Runs efficiently across devices and streamlines penetration testing workflows
Kali Linux could be improved by including more tools. I would personally like to see improvements in Kali Linux, particularly regarding Grub issues that sometimes occur when installing the VM. Additionally, I have experienced problems when updating Kali Linux from a higher version to a lower version, which resulted in crashes. These Grub issues should be resolved. I face significant challenges with Kali Linux regarding a major issue with the Grub loader becoming corrupted, which makes it very difficult to recover data.
Abhishek Saini - PeerSpot reviewer
Professional Services Engineer at Next7 IT
Standardized remote access has boosted secure client support and improved team coordination
OpenVPN Community Edition - powered by TurnKey is very flexible, but there are features that would significantly improve day-to-day operations, especially in MSPs. The biggest improvement I would see is better centralized management, easier routing and network virtualization, more advanced built-in monitoring and reporting, simplified certificate lifecycle management, and stronger integrations with identity providers. One thing we often wish for is something similar to enterprise VPN dashboards where we can instantly see who is connected, which routes are active, failed authentication attempts, and tunnel health. Overall, the core VPN engine itself is solid, but most frustrations are really around management, visibility, scalability, and operational convenience rather than the tunnel functionality itself. The biggest friction point with OpenVPN Community Edition - powered by TurnKey is usually around configuration complexity and troubleshooting, especially in more complex client networks. I encounter issues whenever there are routing and subnet issues, DNS resolution problems, certificates and client configuration management challenges, limited centralized management in the community edition, or documentation dependency.
