Rebuild and run
AI agents rebuild, deploy and replicate the vendor's application in a clean environment.
OPERATIONAL RESILIENCE
Castler rebuilds and runs your critical vendors' software without the vendor, then a named engineer signs the result. Your operational resilience plan gets proof, not a promise.
Critical service
Payment switch
Continuity plan
Run the payment switch without the vendor, using the release sealed in the latest Proof of Recovery.
Proof of Recovery · Engineer's Seal
Rebuilt, deployed and signed for this exact release
Illustrative interface
When a vendor becomes unavailable, the business halts and the loss grows until recovery. Castler's figures show where your operational resilience and software resilience stand today:
40 to 60
critical vendors in a typical estate
2 to 3
covered by deep verification
98%
never independently verified
2 to 4 weeks
and $10,000 to $15,000 per verification
AI agents rebuild, deploy and replicate the vendor's application in a clean environment.
A named Castler engineer signs a numbered Proof of Recovery for your software resilience record.
Premium Recoverability verifies each new vendor release, keeping software business continuity current.
Start with one application, then extend software resilience to every critical vendor.
6 to 18 hours per codebase for software resilience checks, about 90% lower cost than current verification.
Always-current source, configuration and scripts for software business continuity, in Castler's secure custody.
AI agents rebuild, deploy and replicate the application.
A named Castler engineer reviews and signs.
A numbered pack for that exact release, so software business continuity evidence follows the software in production.
Each Proof of Recovery gives your software business continuity team usable documents:
Proof of Recovery pack
A procedure for software business continuity that your team can execute without the vendor.
Independent build evidence for the exact release.
Proof that the production architecture was recreated.
A release-specific inventory of components.
A current measure of verified recoverability.
A named engineer's signature.
Castler maps its software resilience evidence to 17 mandates across 9 jurisdictions:
Regulation
Castler evidence
Operational resilience evidence from the Proof of Recovery and Deployment Runbook
Full Proof of Recovery and Replication Report
RBI IT §12(f) and RBI PSO §17(c)
Deposit, Build Report and Engineer's Seal
Full Proof of Recovery pack
Deposit and Build Report
MAS TRM and APRA CPS 230
Full Proof of Recovery pack
One pack serves as software business continuity evidence for all of them.
Castler's control plane shows every critical vendor, release, verification state, exception and signed Proof of Recovery, so you can track operational resilience and software resilience across the estate.
Live status: mapping, rebuild, deployment, replication and engineer review per release, for software resilience.
Exceptions: missing dependencies, documentation drift, failed builds and unverified critical systems.
Audit-ready evidence: signed operational resilience artefacts for boards, regulators, auditors and insurers.
Five real cases from Castler's incident tracker:
Synapse (2024) left $265M frozen.
AT&T was quoted a 1,050% renewal increase after Broadcom bought VMware (2023).
Nirvanix (2013) gave customers two weeks to move petabytes of data.
CrowdStrike (2024) affected 7,000 Delta Air Lines flights.
Jaguar Land Rover (2025) halted 5,000 suppliers.
Each one tested operational resilience, software resilience and software business continuity at once.
CIOs and CISOs accountable for vendor risk and operational resilience
Compliance teams that own software business continuity evidence
Heads of IT risk and third-party risk management responsible for operational resilience
Boards that need current software resilience proof

With the critical vendor whose failure would stop operations first, such as core banking or payment switch software. Begin with one application and expand your software business continuity coverage.
6 to 18 hours per codebase for a software resilience check, against 2 to 4 weeks for traditional human-led verification.
Castler's artefacts are designed to map to PRA SS2/21, EU DORA, RBI, SEBI and IRDAI requirements for operational resilience, software resilience and software business continuity.
A traditional agreement stores code. Castler rebuilds and runs the software and signs the result for each verified release, so your operational resilience rests on tested software resilience and software business continuity.
