THE PLATFORM
Castler brings custody, verification, exceptions, regulatory evidence, and engineer accountability into one system — so recoverability is continuously visible, not periodically assumed.

ONE VIEW
The platform turns a scattered vendor-resilience programme into a visible operating system.
See every critical vendor, release, verification state, exception, and Proof of Recovery in one view.
Track mapping, rebuild, deployment, replication, and engineer review as each release moves through the engine.
Keep a current evidence trail instead of a report that becomes stale the moment the vendor ships again.
Surface missing dependencies, documentation drift, failed builds, and unverified critical systems before an incident.
Give boards, regulators, auditors, insurers, and customers signed, numbered artefacts they can examine.
Run verification in the cloud and region you choose with role-based access and immutable audit trails.
Software Estate COVERAGE
Your resilience programme is only as strong as the critical vendor you have never tested.
Software Estate COVERAGE
Traditional verification is too slow and expensive to scale. Castler is designed to cover the critical systems that normally remain untested.
