I think it's quite interesting that a couple of companies are coming up with so called ''secure enterprise browsers.'' Seems to be a new security category and another company that does the same is Talon, see third link. https://techcrunch.com/2022/02/01/island-stealth-enterprise-browser/ https://www.island.io/blog/the-best-enterprise-security-solution-of-the-year-is-a-browser https://venturebeat.com/security/talon-enterprise-browser/
BTW, this is another interesting article about Talon and Island, who both make enterprise browsers focused on security. There is also a company named Seraphic Security, see second link. But they don't develop a browser themselves, it's more of a browser security add-on if I understood correctly. Same goes for Guardio, but Guardio isn't that advanced. https://en.globes.co.il/en/article-talon-and-island-do-battle-for-browser-security-1001421188 https://seraphicsecurity.com/product/
