CASTLER SRP
Signed Proof of Recovery across your entire software vendor estate — at speed, using AI, verified by engineers
THE PROBLEM
You run core operations on software you did not build. When a vendor becomes unavailable, the business halts and the loss compounds until recovery. It has already happened, in five different ways.
Different causes. Identical outcome: the software stops, and the loss grows until recovery.

Never rebuilt
The deposit has not compiled outside the vendor's infrastructure.
Never deployed
The runtime and operating procedure remain untested.
Never proven
No signed evidence shows the system runs without the vendor.
Stale by design
The stored release may no longer match production.
THE COVERAGE GAP
Not by choice. By economics. Human-led verification makes 100% vendor coverage too slow and too expensive, leaving the majority of critical vendors as unverified risk.

FREQUENTLY ASKED QUESTIONS
Software recoverability is the ability to rebuild, deploy and operate critical vendor software without relying on the vendor. Castler verifies this independently and records the result as a signed Proof of Recovery.
Traditional escrow stores source code. Castler SRP adds independent build, deployment and replication verification so regulated institutions receive current evidence that the deposited release can actually be recovered.
Each verified release can include a Build Report, Deployment Runbook, Replication Report, SBOM, Confidence Score and an Engineer’s Seal from the named Castler engineer who reviewed the evidence.
Yes. Institutions can begin with one critical application and expand verification across their Software Estate as new vendors and releases enter the platform.
