ExpressVPN has announced that its VPN app for Windows has been given a clean bill of health following an independent security audit conducted last year.
From November to December of last year, the cybersecurity firm F-Secure conducted a penetration test of the company's Windows client in an attempt to identify any potential security weaknesses within the app. More specifically, ExpressVPN wanted to know if an attacker could use its Windows app to execute code remotely while also ensuring that no user information was disclosed or IP addresses were leaked.
In its security assessment of version 10 of ExpressVPN's Windows app, F-Secure reported that none of the targeted vulnerabilities were found. According to the report, it was not possible to gain information about the company's clients or out of network traffic from its app. At the same time, the app itself is not susceptible to Man-in-the-Middle (MitM) attacks, TLS downgrading, packet injection or other methods used to execute code remotely.
Of the security issues flagged by F-Secure, one was low-severity while the others were informational. No critical, high or medium issues were found and ExpressVPN has since fixed the issues raised in the firm's report. These fixes were also confirmed by F-Secure during a re-test which took place in February of this year.
More audits to come
In addition to letting companies know about potential security flaws in their software and services, VPN audits also make it easier for consumers when it comes to picking out the right VPN for their needs.
While ExpressVPN tests its software internally, the company also regularly engages with independent security experts to assess its products and validate the accuracy of its claims. Going forward, the company plans to conduct even more audits this year on all of its VPN clients, core technology and even its privacy policy.
In the past, ExpressVPN has had audits conducted on its proprietary VPN protocol Lightway, its browser extensions, its build verification process and its in-house technology Trusted Server by both PwC Switzerland and Cure53.
Head of cybersecurity at ExpressVPN, Aaron Engel provided further insight in a blog post on the recent independent security audit from F-Secure as well as the company's plans for future audits, saying:
“The report from F-Secure showcases the strength of our product and validates the high-quality work that ExpressVPN engineers and security experts have been doing. This is the first of multiple audits to come in 2022, and we are committed to continuing to deliver independent reports on all of our client apps, core technology, privacy policy, and more.”
