Find the gaps before someone else does

I'm Josh Fischer. I find the gaps in systems, from the agent and application layer down through the services, infrastructure, and network underneath, and then I help close them. I work alongside your team rather than handing findings over a wall. BirdyFoot is my practice, and I've been running it on my own since June 2025.

What that looks like

Who it's for

Teams running something that can touch something real: a customer record, a payment, an internal service, another system. AI agents are the newest version of that problem and the one I write about most, but the shape is an old one. Something is trusted with more reach than anyone intended, and the layer above assumed the layer below was checking.

That is why I don't stop at the application. A finding at the agent layer is often only interesting because of what the network or the identity configuration underneath it allows, and you cannot see that from one end.

If you're still prototyping, the free writing and labs are probably a better use of your money than I am. Come back when it's wired into production.

Tell me what you're building and what worries you about it. I read everything that comes through here and reply personally. No sequence, no SDR, no calendar wall.
