I've worked in IT consulting for over 10 years and have never once lied about the capabilities of a product. I have said, it doesn't do that natively, but if that's a requirement we can scope how much it would take to make it happen. Sadly my company is very much the exception.

The worst I saw was years ago I was working on an infrastructure upgrade of a Hyper-V environment. The client purchased a backup solution I wasn't familiar with but said it supported Hyper-V. It turns out their Hyper-V support was in "beta". It wasn't in beta. They were literally using this client as a development environment. It was a freaking joke. At one point I had to get on the phone with one of their developers and explain how high-availability and fail-over worked.

eh DHCP isn’t really important right? obviously if it hasn’t changed since the 80’s why would you need to reboot your server.

what are vulnerabilities?

The contractor I worked for was run by a man who used to say "if the contract says they'll blow up the contractor on delivery, we're putting in a bid and solve the problem later"

I worked in government contracting (and government, for that matter) for years and that blows my mind. I can't remember the details, but if you even had a bad reviews, much less being found noncompliant, it could disqualify you entirely from some contract vehicles for a matter of years. Wild that there's some agency that somehow lets people get away with fraud.

Also, if that cost the government money, there's a chance you could report that after the fact and make some money.
