CSTI is an IT service provider in Thônex (Geneva), founded in 2009, that hosts services for small and medium-sized businesses alongside managed IT, consulting and hardware sales. Its hosted products include virtual private servers, Microsoft Exchange mailboxes, Veeam-based backup, a password manager (CSTI Vault), a file sync and sharing service (CSTI Drive), domains and Sophos security packages.
CSTI states that its data centres are exclusively in Switzerland and that it operates them itself; mail is described as running on geo-redundant infrastructure in Switzerland, and VPS can be made geo-redundant as an option. The data centre locations are not published.
