White House communications director previously revealed (after “Signalgate”) that Signal was an approved and whitelisted app for gov’t officials to have on work phones and even discuss top-secret matters on. But I haven’t heard that TeleMessage was approved (and I’d have serious questions if it were given the foreign intelligence factor). Anyone know if there is a clear answer to whether it’s been approved?
The correct answer is no one outside US Government IT knows for sure what is or isn't approved per their own rules. Every article (and comments therein) are just speculation and people trying to confirm their own biases, desperately looking for something to blame someone for, to produce more rage-bait and thus feed more ad clicks. Every single article is written with the presumption that there are no actual IT people…
Veterans Affairs actually publishes a list of approved software as part of their Technical Reference Model: https://www.oit.va.gov/services/trm/ (don’t know how complete it is)
But I’m not aware of other agencies doing this. I suppose that VA, given the nature of what they do, likely feels that there is less risk in publicising this information
There’s also the FedRAMP program for centralized review of cloud services - fedramp.gov - I haven’t looked to see if Telemessage is listed as approved but I see some references to FedRAMP and Telemessage online suggesting that it may be
Another source of info is SAM.gov - https://sam.gov/opp/ab5e8a486e074d73bfe09b383ba819ab/view (that’s for NIH) - if there is an agency paying for it, you can assume they’ve approved it for use (or are in the process of doing so) even if they haven’t otherwise publicly said they are. But, not all contracts are public, so just because you can’t find it on SAM.gov doesn’t mean it doesn’t exist
