SIO is an italian information technology company.
Founded in 2003, SIO initial focus was in wiretap and location trackers that evolved into their Xtreme product line.[1][2]
In 2021, SIO was found reselling Cy4Gate spyware Epeius.
The Italian’s prosecutor office of Naples later briefly suspended SIO’s wiretapping authorization.[3][4]
After acquiring ASIGINT in 2019/2020, SIO started distributing the “Spyrtacus” spyware on the Google Play Store, but was later removed for a breach of the terms of service.[5] In 2025 it was reported that the spyware was not available on the Store but it is still distributed by targeted web pages posing as WhatsApp and other popular apps.[6]
