KeepSolid

KeepSolid is an American software company headquartered in New York City. Its best-documented consumer-facing product is VPN Unlimited, a virtual private network service designed for desktop computers, mobile devices, and web browsers. The service is intended to route a user's internet traffic through encrypted VPN connections, supporting privacy-oriented use cases, access to geographically distributed endpoints, and connection security on potentially untrusted networks. VPN Unlimited was initially launched for iOS in 2013 and subsequently expanded to additional operating systems. Its supported platforms include Windows, macOS, Linux, Android, and iOS. Browser extensions have also been made available for Mozilla Firefox, Opera, Microsoft Edge, and Google Chrome. This cross-platform approach positions the product as a general-purpose VPN rather than a service limited to a single device category. The service supports several connection technologies, including IKEv2 and OpenVPN, as well as KeepSolid Wise, a proprietary protocol intended to make VPN traffic more difficult to identify or block by routing it through TCP port 443. In 2019, VPN Unlimited added the open-source WireGuard protocol to its available protocol selection. The product also includes a kill-switch function intended to interrupt connectivity if the VPN connection fails, and it is marketed with a no-logs privacy policy. Available server types have included general-use endpoints as well as options aimed at personal VPN use, peer-to-peer activity, streaming, and torrenting. VPN Unlimited has been offered through monthly, annual, three-year, and lifetime subscription plans. A lighter freemium version for Android and iOS was introduced in November 2018, extending the product's model beyond conventional paid subscriptions. Reference material describes a network of more than 3,000 servers in over 80 locations, although the exact size and composition of the network can change over time. The product has received coverage from technology publications. PCMag gave VPN Unlimited an Editors' Choice award in May 2016 and later reviewed its Linux client in 2019. Macworld, Tom's Guide, TechRadar, and PCWorld also assessed the service during the late 2010s and early 2020s. The reviews generally highlighted usable performance, approachable applications, or comparatively affordable plans, while also noting limitations such as a relatively small server footprint in comparison with some competitors and a limited set of options in the Windows client. The supplied reference material does not establish KeepSolid's founding year, founder, ownership structure, public listing, revenue, or a broader corporate portfolio beyond the VPN Unlimited product. Accordingly, those details are left unreported rather than inferred. KeepSolid's documented market identity is primarily that of a software and privacy-services provider operating through digitally distributed VPN applications and subscriptions.

KeepSolid's documented history is closely associated with VPN Unlimited, its best-known software product. The service began in 2013 as an iOS application. It later expanded to Windows, macOS, Linux, Android, and browser environments, allowing users to manage VPN connections across common desktop, mobile, and browsing platforms. The product gained external recognition in May 2016, when PCMag selected VPN Unlimited for an Editors' Choice award. In November 2018, KeepSolid broadened the mobile offering by releasing a lighter freemium version for Android and iOS. This created an entry-level route for users who did not begin with a standard paid subscription. A further technical development came in 2019, when VPN Unlimited added WireGuard to its supported protocols. WireGuard joined IKEv2 and OpenVPN, while the service also maintained its proprietary KeepSolid Wise protocol. KeepSolid Wise was designed to route traffic through TCP port 443, a technique intended to make VPN traffic harder to detect or block in restrictive network environments. The service's feature set has included a kill switch, a no-logs privacy policy, and specialized endpoints for purposes such as streaming, peer-to-peer sharing, torrenting, and personal VPN use. Subscription choices have included monthly, yearly, three-year, and lifetime plans. Reference material describes a network exceeding 3,000 servers across more than 80 locations, with coverage spanning countries and territories in North America, Europe, Asia, Africa, South America, and Oceania. VPN Unlimited received continuing attention from technology reviewers. PCMag assessed the Linux client in 2019, while Macworld and Tom's Guide discussed the service's interface, speed, and subscription value in the same period. TechRadar reviewed it in 2021, praising performance and pricing while noting that its server network was relatively small compared with some competing services. PCWorld's October 2021 assessment of the Windows client found it useful but comparatively limited in configuration options. The supplied material does not document KeepSolid's incorporation date, founder, ownership history, revenue, public-market status, or executive leadership. It also does not establish a separate chronology for a larger portfolio of KeepSolid products. Therefore, the available history supports a focused account of the company's VPN software development and public product reception rather than a complete corporate history.
