Here is some more data regarding Chrome vs Safari, from https://www.zerodium.com/program.html https://www.zerodium.com/program.html These are prices for 0-day exploits. For desktops : $250,000 - Chrome RCE + SBX (Windows) including a sandbox escape $80,000 - Safari + SBX including a sandbox escape (it is on the graphical table below the changelog) $100,000 - Chrome RCE without a sandbox escape $50,000 - Edge, Safari, Firefox RCE without a sandbox escape To me, these prices clearly indicate that Safari is a lot easier to exploit than Chrome. They also indicate that the Chrome sandbox is a lot harder to bypass (look at the relative price differences). For mobile the payouts are similar which indicates that Apple has paid more attention to IOS security-wise. That is also the consensus amongst most security experts I know.
