PERSLIS DEFENSE · CONNECTION

Connect all of your endpoints right into the brain.

Old computers, no API, no problem. The brain drives legacy software the way your operators do — through its own buttons, fields and screens — and reaches mainframes through the ways in they already have. Every running system you own, in one place, under one brain.

No API? No problem.

Most integration starts with “first, give us an API”. The systems that matter most never had one. Perslis reads the program’s own controls — every button, field and menu — and turns them into actions it can take and facts it can read. Nothing gets rewritten, nothing gets ripped out, and nothing waits on a new program of record.

Nobody gets to start over. The GAO found a Defense Department system that coordinates the operational functions of the nation’s nuclear forces running on an IBM Series/1 — “a 1970s computing system” — with 8-inch floppy disks (GAO-16-468, May 25, 2016).

One brain over all of it

Every systemIts state becomes facts, read straight from its own controls and data. Its operations become a fixed list of actions.
One brainSees them together, learns across them from what goes wrong, and only takes the actions the floor allows — with a receipt for each.

The old system stays. The brain decides what reaches it, and every action it takes on it is written down.

Where to start

Pick one job on one old workstation. We map it, run it in an isolated copy, and run the brain in shadow mode next to the operator: it writes down what it would have done and refused, and why, and touches nothing. Then the next system, into the same brain.
