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.

[–] dan@upvote.au 2 points 5 days ago* (last edited 5 days ago) (1 children)

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.

[–] Brkdncr@lemmy.world 1 points 5 days ago

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.

Only if the site they’re visiting isn’t using HSTS, but it’s possible

[–] foobaz@lemmy.world 3 points 6 days ago (1 children)

I don't think this is correct. HSTS only prevents downgrading.

HSTS says it must be encrypted but a proxy will create two connections and look at it clear in the middle. On the other hand cert pinning says it must be a specific cert that breaks the site if decryption is used. Apple is big on doing that for a lot of their site and apps.

Yep, they're not decrypting HTTPS, I've triple checked. But we do have an MDM forced proxy service that does check any non-encrypted traffic...
