I know Safari can be fast, but is it up to scratch in terms of security? I remember reading somewhere that it doesn’t even isolate tabs as separate processes.

That hasn't been true in like 10 years. You can check the process hierarchy yourself in Activity Monitor and see its many processes, including one for each loaded site. It also uses separate processes for sandbox access, image decoding, video decoding, Metal compilation, and audio, among others.

I thought the SLAP exploit specifically worked only in Safari due to deficient site isolation, though? https://open-web-advocacy.org/blog/slap-and-flop--apples-lac...

That's from February of 2025.
