Cyrillian

Secure browsing for safer intelligence gathering

ABout The brand

Disposable browsing for secure investigations

Cyrillian gives analysts and investigators a clean, isolated browser for online research. Each session launches fresh and disposable, keeping hostile pages, tracking and browser based threats away from your network and your identity. When the session ends, it is gone. Built for open source intelligence work and sensitive online investigation, Cyrillian reduces the digital footprint investigators leave behind and helps organisations run online enquiry safely, lawfully and repeatably.
