Open Source Network Security Software
Network Security tools manage secure access to servers, databases, and internal web applications. These tools encrypt traffic through tunnels and bastion hosts to prevent unauthorized access to remote endpoints. This type of software is for system administrators and developers who need to manage SSH, RDP, and Kubernetes clusters. Self-hosting these apps ensures that authentication logs and connection keys remain on private hardware. This approach prevents external providers from accessing the internal network topology or monitoring the traffic flowing between remote terminals.
This page lists 10 open source tools in the Network Security category. The most popular are JumpServer, Teleport and OpenVPN. Most use the Apache-2.0 or GPL-3.0 license, and 7 offer an official Docker image.
