PIA S5 comes from the same crop of Hong Kong-located proxy providers that appeared between 2022 and 2023, trying to emulate the hugely popular 911 S5 which was shut down by American authorities. The provider has expanded its range of services with more products, mostly related to residential proxies that are cheap by western standards and scale well. PIA S5 offers access to two proxy types: residential and ISP (static residential), each coming in two variations with or without PIA's installable proxy manager application. The provider advertises to control 350 million IPs from around 200 countries with targeting options including global, country, state, city, ASN, and ZIP code levels. PIA S5 uses a one-time purchase model charging per IP, with packages ranging from 200 IP credits at $0.25/IP to 40,000 or more at $0.045/IP. The provider offers a proxy manager app for Windows, macOS, and Debian-based Linux systems that provides an interface for filtering available proxies by location, ISP, and ping. PIA S5 also offers Android and iOS apps for using proxies on smartphones, working similarly to a VPN but providing residential IP addresses. The provider has a dashboard available in nine languages including Russian, Spanish, Portuguese, and Chinese, though the design doesn't fit well on laptop screens. PIA S5's documentation hub includes a lot of content but has poor quality and structure, with most articles covering the SOCKS5 residential product. The provider offers 24/7 live chat support via email, though response times can be up to 48 hours outside business hours.
