I have some ideas about F-secure safe's feature to add
1. Banking protection can add some shopping sites support, and can let users add whitelist and blacklist
2. Safe keyboard can be added, which will encrypted your words that protecting your typing safe
3. F-secure safe mobile (Android & IOS) can be added web protection for Chrome and Adnroid browser
4. F-secure safe mobile (Android & IOS) can be added Block all unknown calls feature
5. Firewall's setting can be better, for instance, can add network atteck protection, or flood atteck protection.
