October 2025 - Comparative Analysis of Sailfish OS

As mentioned last year, Sailmates received a grant from NLnet to study various aspects of Sailfish OS. Specifically:

• the Secrets component (responsible for cryptography);
• the Ofono fork (which is responsible for 5G support, among other things);
• Sailjail sandboxing for application sandboxing.

The first part of the study, concerning the Secrets component, is complete and can be accessed here: SailfishSecrets.pdf.

This study is a comparative analysis of Sailfish OS, Android and iOS from a security viewpoint with regard to the cryptography-related components.
