> All these are due to laws and regulations that are there to protect the big companies and don’t take into consideration users This feature is not due to laws and regulations. The user in this case is the presenter who clicks the button to enable screenshot protection on their meeting. This is Microsoft trying to deliver a feature their users want , not laws and regulations making them do something their users don’t…

But it’s literally the dumbest feature ever. There’s absolutely nothing preventing a user from pulling out their phone and taking a picture of any slide they want. Or having a camera recording the whole session out of view of their webcam. It is security theater at its peak.

Or use an hdmi capture card.

Nah, this would stop a lot of threats. I'm an example of that threat. I'm a freelancer who often has video calls with new clients. Sometimes I surreptitiously screen cap demos or presentations. It would be very difficult to use a phone that way without breaking the conversational flow. Other supposed workarounds would require much more preplanning. Like I'd need to know that there was something worth capturing.

RDP into computer that has meeting running and then screenshot from the external computer running RDP .

Yep, I already covered workarounds that would be possible with preplanning.

LOL Another stupid feature (enforced by regulations/law/policies) that has no real world use, besides making us users angry :-( Like Google collecting all of our location history for their own usage, but not allowing us to see it via web anymore (only on mobiles), or having the android dialer not allowing us to record our own phone conversation (easily circumvented), or movie/music/game publishers not allowing us to…

Nothing, /yet/

> Yeah, there are threat models that won't be stopped here Like running windows in a VM or using an HDMI capture card. And are they going to break running teams meetings when using moonlight etc. with this? If you are OBS capturing during the meeting does it get blacked out or just breaks your recording?

You don't need to elaborate on mechanisms for bypassing because you're already imagining a threat actor that is out of scope. This is primarily about blocking accidental leaks by regular employees who were asked to not record but ignored it. This kind of reuse of content happens all the time in companies of any significant size and isn't entirely stopped by simple requests or watermarks. This tool gives companies one…

And also gives legal teams more foundation to stand on, bypassing this isn't trivial so it shows real intent

just because it isn't perfect doesnt mean it's "dumbest". snapchat, 4chan, etc. will foil 99% of users, who don't think to take/are incapable of taking that next step.

At some point, you need to trust your staff. If you do not trust them to keep confidential information private, then why are you giving them the information in the first place?

I have some friends who work in a medical facility. They get an extreme amount of training on patient privacy laws and constant reminders not to get sensitive patient information on to their personal devices. Despite the intense training and constant warnings, it happens constantly . And that’s just the cases they know about and address. You have to be able to trust your staff, but you also have to be realistic that…

Extreme amount of training? More like once a year online HIPAA test that everyone blows through with the occasional CISO phishing campaigns that at least one person fails.

In a 1:1 format this would be effective in preventing some forms of misuse because it would be obvious if an individual took out their phone and pointed it towards the screen.

Easily circumvented: Use two monitors, one positioned out of view. Use a teleprompter mirror with a camera behind the mirror. Use a video capture device, record on a separate computer. I'm sure there's sneakier ways to perform this...

Your “easy” circumvention requires a second monitor, a teleprompter mirror, a camera, a separate computer and a video capture device. Remember, most people who use Teams don't work in tech. And for them, that’s not “easy”. Barely any normal people have that kind of equipment just lying around, along with the expertise and desire to set all that up, ready for a teams meeting.

For every 100 people who might decide to take a screenshot during a teams meeting, I doubt there’s 1 person who has all that equipment set up and ready to go. You don’t need to make something 100% effective to get a benefit from doing so.
