Chrome 63 offers even more protection from malicious sites, using even more memoryMay 16, 2018
To further increase its enterprise appeal, Chrome 63—which hit the browser’s stable release channel yesterday—includes a couple of new security enhancements aimed particularly at the corporate market.
The first of these is site isolation, an even stricter version of the multiple process model that Chrome has used since its introduction. Chrome uses multiple processes for several security and stability reasons. On the stability front, the model means that even if a single tab crashes, other tabs (and the browser itself) are unaffected. On the security front, the use of multiple processes makes it much harder for malicious code from one site to steal secrets (such as passwords typed into forms) of another.
