EU CRACyber Resilience Act

The Cyber Resilience Act sets cybersecurity requirements for products with digital elements across their lifecycle — secure development, vulnerability handling, and support obligations for manufacturers placing software on the EU market. This guide explains the requirement, scope, timeline and evidence mapping for software escrow and Software Recoverability.

THE GLOBAL REGULATORY MANDATE

The regulator stopped asking “Do you have escrow?” It now asks “Can you prove recovery?”

Across financial regulation, cyber-resilience rules and global assurance standards, the direction is converging: critical third-party software must remain current, testable and recoverable when its provider fails.

1 · WHAT THE REGULATION IS

What is EU CRA?

Cyber Resilience Act is the governing framework or standard represented on this page.

The Cyber Resilience Act sets cybersecurity requirements for products with digital elements across their lifecycle — secure development, vulnerability handling, and support obligations for manufacturers placing software on the EU market. For a CIO, CISO or compliance officer, the practical issue is whether a critical third-party application can remain available when the provider fails, exits, is acquired or can no longer support the product.

Software escrow addresses custody: who holds the source code, build materials and documentation. Software Recoverability addresses the next question: whether those materials have been independently rebuilt, deployed and tested. The distinction matters because an agreement and a deposit do not prove that recovery can be completed within the institution’s operational tolerance.

Castler therefore treats the requirement as part of vendor onboarding. The agreement and first deposit are established when the relationship begins, every release is captured, and the verification evidence is renewed before an auditor, insurer or supervisor asks for it.

2 · EXACT REQUIREMENT

Cyber Resilience Act

In summary

Security-by-design and secure development across the product lifecycle; Vulnerability handling and a software bill of materials (SBOM); Defined support and update obligations for digital products; Assurance over third-party and embedded components

Reference: Cyber Resilience Act. For legal interpretation and exact operative wording, use the current official text and advice applicable to your supervisory perimeter.

In practical terms, compliance requires more than a clause in the vendor contract. The institution must identify which applications are critical, establish custody or source-code access, ensure the deposited materials remain current, document release conditions and maintain evidence that continuity or exit can be executed.

Where the framework requires tested recovery, resilience or credible exit, a stored deposit is only the starting control. Independent build evidence, deployment instructions, architecture replication and a signed engineer review show that the recovery path has been exercised rather than assumed.

3 · Who it applies to

Entities and teams responsible for security-by-design and secure development across the product lifecycle

Entities and teams responsible for vulnerability handling and a software bill of materials (SBOM)

Entities and teams responsible for defined support and update obligations for digital products

Entities and teams responsible for assurance over third-party and embedded components

The accountable group normally includes technology, information security, outsourcing, procurement, compliance, business continuity and the business owner of the supported service. Scope should be based on criticality, not only contract value.

4 · Compliance timeline

EUROPEAN UNION · REGULATION (EU) 2024/2847

Confirm the current implementation status and any jurisdiction-specific deadline against the official text and supervisory guidance applicable to your entity.

Institutions should work backwards from the operative date. Vendor identification, agreement execution, repository integration, initial deposit, reconciliation and first verification all require lead time. Onboarding-first implementation avoids a deadline-driven retrofit.

5 · CONSEQUENCES

What happens when the evidence is missing?

Failure to maintain credible third-party resilience can lead to audit findings, remediation programmes, increased supervisory scrutiny, reputational damage and operational loss during a provider disruption.

The operational consequence can be more severe than the supervisory consequence. If a critical provider fails and the deposited software cannot be built or deployed, the institution may breach customer commitments, impact tolerances, market obligations and board-approved continuity objectives while the technical team reconstructs undocumented knowledge under incident conditions.

A current custody record and signed Proof of Recovery reduce that uncertainty. They do not replace legal analysis, incident planning or the institution’s own controls; they create tested technical evidence that those controls rely on.

6 · CASTLER EVIDENCE MAPPING

How Castler maps to EU CRA.

The mapping is specific: each obligation is paired with the Castler artefact or operating control that provides relevant evidence. It is not a claim that software alone guarantees compliance.

7 · FREQUENTLY ASKED QUESTIONS

EU CRA questions from compliance and technology teams.

Does having a software escrow agreement satisfy the requirement?

An agreement can satisfy the contractual custody element, but EU CRA also expects the institution to manage continuity, third-party risk or recovery evidence. The exact answer depends on the clause and supervisory perimeter.

How current must the source-code deposit be?

The deposit should track the production release. Automated repository capture, version history and release identifiers make it possible to show that updates and fixes are included rather than relying on the original filing.

Does the software vendor need to participate in every verification?

The vendor participates in onboarding, deposit setup and structured reconciliation where documentation is missing. Verification is then designed to run independently so the vendor does not need to be present every time.

What evidence should be presented to an auditor or supervisor?

Present the executed escrow arrangement, deposit and release history, build report, deployment runbook, replication report, SBOM, confidence score, exception record and signed Proof of Recovery for the release in scope.

Can an institution begin with custody and add verification later?

Yes. Cloud Custody establishes the current deposit and agreement. The same record can be upgraded to Standard or Premium Software Recoverability without creating a new custody foundation.

How often should recoverability be re-tested?

Re-test when the vendor releases a material version and according to the institution’s criticality, regulatory and board-approved assurance cycle. Per-release verification avoids stale annual evidence.
