Vendor contract expiry
A department's application-maintenance contract ends without a workable transition plan. The service continues to run, but source, deployment knowledge and operational control remain concentrated with the outgoing vendor.
GOVERNMENT & PUBLIC SECTOR
Central and state departments, PSUs and civic bodies depend on third-party citizen-service, revenue-management and enterprise software. Castler independently rebuilds critical vendor applications and produces signed Proof of Recovery to support strategic control, tested continuity and public-sector cyber resilience.
PUBLIC-SECTOR SOFTWARE ESTATE
Independent recovery evidence for essential digital services
SIGNED OUTPUT
Proof of Recovery · per application · per verified release
THE PROBLEM
Government functions increasingly run on outsourced applications and vendor operating knowledge. Without current custody, exit documentation and an independently tested recovery path, contract change or supplier failure can become a public-service continuity event.
A department's application-maintenance contract ends without a workable transition plan. The service continues to run, but source, deployment knowledge and operational control remain concentrated with the outgoing vendor.
A supplier supporting several public-service applications is acquired and its product roadmap changes. Multiple departments face the same discontinuation risk at the same time.
A bespoke e-governance platform depends on a small technical team. Staff departure or supplier failure leaves the department with code and documentation that have never been tested for independent recovery.
THE GOVERNANCE REQUIREMENT
MeitY guidance for outsourced government projects calls for control over source code and associated documents, exit planning, disaster recovery and business continuity. CERT-In's government-entity guidelines require BCP/DR preparation and annual testing, while its SBOM guidance recommends software-inventory requirements in public-sector procurement.
Government control over source code, documentation, exit planning and outsourced-project continuity
Custody record + Deployment Runbook
Prepare, test and implement BCP and DR; annual testing; vendor security governance
Proof of Recovery + signed verification evidence
SBOM requirements recommended for government, public-sector and essential-services procurement
SBOM + release-specific evidence pack
THE SOLUTION
Castler's agentic verification engine rebuilds critical government software in a clean environment without depending on the vendor's operating team. A named Castler engineer reviews the evidence and signs the resulting recovery pack.
E-governance portals, service-delivery applications and grievance systems kept current in custody and backed by release-specific recovery evidence.
Revenue collection, registration and land-record platforms covered under a verified public-sector Software Estate programme.
ERP, HRMS, procurement and supply-chain platforms independently rebuilt and verified against the declared architecture.
REPRESENTATIVE PROGRAMME
This is an illustrative public-sector remediation model, not a claimed customer engagement. Scope and timelines depend on application complexity, procurement terms, deposit quality and vendor cooperation.
Map citizen-service, revenue, land, ERP and PSU systems by public impact, supplier concentration and transition readiness.
Bring source, documentation, deployment definitions, exit plans and runbooks into controlled custody and identify missing artefacts.
Rebuild each scoped release independently, test the recovery procedure and issue the signed Proof of Recovery pack.
