You’re sure they aren’t decrypting your traffic? Check the root cert of any site and see if it’s their own root.
Larger companies that monitor for corporate passwords being entered on third-party sites usually use a browser extension that's force-installed using Chrome Enterprise. That's especially the case if they mandate the usage of Chrome.
Why do you say usually? It’s not what I do. I MitM every machine.
It's what I've experienced at FAANG companies. MitM isn't used and would break certificate pinning on sites (including internal tools) that use both certificate pinning and HSTS. The Chromium source code has a list of domains that are hard-coded to only accept particular root certificates.
I don’t MitM sites that are know to break. I also don’t decrypt healthcare or banking sites. In most cases you wouldn’t know it’s happening unless you look at the cert issuer.
