Vendor insolvency
A billing platform vendor enters liquidation. Prepaid top-ups, post-paid billing and roaming settlement face disruption while the operator reconstructs the system from incomplete documentation.
TELECOM & CONNECTIVITY
Telecom operators worldwide depend on third-party BSS, OSS and network-management software from vendors they do not control. Castler independently rebuilds those vendor applications and produces signed Proof of Recovery — supporting cyber-security and critical-infrastructure resilience obligations across every major regulatory jurisdiction.

THE PROBLEM
Telecom operators have digitised every layer of the network, from subscriber charging to network assurance. Each critical function depends on software, specialist knowledge and release artefacts held by a third-party vendor.
A billing platform vendor enters liquidation. Prepaid top-ups, post-paid billing and roaming settlement face disruption while the operator reconstructs the system from incomplete documentation.
A foreign OSS vendor is acquired and the regional product variant is discontinued. The operator must migrate a critical system without a tested independent recovery path.
A ransomware incident disables a network-management supplier. Operational visibility degrades while the vendor restores its own environment and the operator waits for support.
THE REGULATORY MANDATE
Regulators across the UK, EU, Singapore, Australia, the Middle East and India classify telecom as critical national infrastructure. Recovery obligations — including third-party software continuity, incident response, and cyber-security controls — are mandated under frameworks including EU NIS2, DORA, the UK PRA's operational resilience rules, MAS TRM, APRA CPS 230, and India's NCIIPC and CERT-In directions.

THE SOLUTION
Castler's agentic verification engine rebuilds critical telecom 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.
Billing platforms, charging systems and fraud-management software kept current in custody and backed by release-specific recovery evidence.
Network-management, spectrum, inventory and fault-management platforms covered as part of the operator's critical Software Estate.
Cloud-native network functions, orchestration layers and SDN controllers verified against the declared production architecture.
REPRESENTATIVE PROGRAMME
This is an illustrative telecom remediation model, not a claimed customer engagement. Scope and timelines depend on application complexity, deposit quality and vendor cooperation.
Prioritise BSS, OSS, charging, assurance and orchestration systems by operational consequence and vendor dependency.
Bring source, configuration, infrastructure definitions and documentation into controlled custody with an agreed update cadence.
Rebuild and deploy each release independently, close deposit gaps and issue the signed Proof of Recovery pack.
