ExpressVPN has released leak testing tools under an open source license. They were developed by the company’s Privacy Research Lab and have been released under an MIT license.
The tools were build for two reasons:
- To provide robust, automated regression testing of ExpressVPN applications
- To facilitate leak testing investigations to further strengthen those applications
The tools are written primarily in Python, and the company’s hope is that they will provide users and third parties with ways to verify the quality of VPN providers, create a high benchmark for VPN protections, and bring together experts to improve VPN security and privacy.
