Build Yours. Watch Theirs.

🤖 Build yours. Watch theirs. 🤖

Last week I wrote about building your own AI assistant > pipe by pipe, weld by weld.

Here’s the part I left out.

Every vendor on your stack is doing the same thing right now. Some of them are building it well. Some of them are bolting it on. Most of you have no idea which is which.

That’s the next attack surface > the agents your vendors deploy and never tell you about.

🤖 Their model gets a customer record you handed them.

🤖 Their agent talks to a fourth party you’ve never heard of.

🤖 Their prompt gets injected. Their session gets stolen. Their data gets YOU.

The quiet part, said out loud: your AI vendors will get hacked. Are you ready?

If your TPRM program still grades vendors on a 12-month-old SIG questionnaire, you’re not measuring the AI surface. You’re measuring last year’s surface.

Don’t get hacked through a robot somebody else built.
