Not so much irony as it's a great vector to get inside an org. Security / monitoring agents that you deploy everywhere and don't suspect when you see they exfiltrate data, since you're expecting the telemetry anyway.
Every time some security compliance goon comes by telling me to install an agent on all of our servers to meet some security compliance requirement, I remind them that they are asking me to install a backdoor on our servers and handing the keys to a 3rd party.
Well honestly, this security person thinks its a terrible idea - but needless to say the people selling those systems disagree - and for non-technical management, it ticks the compliance box and they get back to their jobs.
You will not be faulted for anything if the security company gets hacked and you get hacked through it. Probably a lot of sleepless nights to fix your infra, but that's it.
