Technology
Secure-by-default open source images and libraries that help software and SaaS companies pass security reviews faster and cut engineering toil.
The challenge
Technology companies build on a deep stack of open source containers and language dependencies, and every one of those components is a potential entry point for a vulnerability, a licensing dispute or a malicious package. Security and procurement reviews from enterprise customers routinely stall deals while teams chase down CVE lists, provenance questions and SBOM requests that engineering was never resourced to answer quickly.
Meanwhile, the engineering effort spent patching base images, triaging low-value CVEs and vetting packages pulled from public registries such as PyPI or npm draws attention away from product work. As AI-assisted coding tools pull in dependencies faster than teams can review them, the risk of credential-harvesting malware or typosquatted packages entering the build pipeline grows, and the manual toil of keeping images current becomes harder to sustain at scale.
Key solutions
Secure-by-default OSS built to scale
Teams standardise on minimal, hardened container images so that new services start from a low-CVE baseline rather than accumulating vulnerabilities from general-purpose base images. This shifts security work upstream, meaning fewer emergency patches later and less time spent justifying open findings to customers or auditors during reviews.
Speed through security and procurement reviews
Engineering and security teams present enterprise buyers with a consistently low or zero-CVE posture and a documented remediation service level, which shortens the back-and-forth typical of vendor security questionnaires. This helps deals move through legal and procurement gates without ad hoc scrambles to produce evidence.
Reproducible, auditable, verifiable builds
Build pipelines are configured to produce images with signed provenance and attested SBOMs, so any artefact deployed to production can be traced back to its source and build process. Security teams use this to answer audit and customer questions about build integrity without reconstructing history manually.
Malware-resistant language dependencies
Development teams turn off direct access to public package registries and instead pull Python and JavaScript dependencies from a curated, continuously remediated catalogue. This removes a recurring source of malware triage work and reduces the chance that a compromised upstream package reaches a build.
Reduced engineering toil
Platform teams replace ad hoc, in-house image hardening and patch cycles with continuously rebuilt, minimal images maintained on a defined cadence. Engineers spend less time chasing base-image CVEs and more time on product features, since patching work that used to sit with internal teams is absorbed elsewhere.
Core capabilities
Minimal container images
Purpose-built, distroless-style images with a reduced package footprint, limiting the packages that can introduce vulnerabilities.
Attested SBOMs
Verifiable software bills of materials generated and signed for each image build, supporting audit and customer disclosure requests.
Chainguard Libraries
A curated catalogue of Python and JavaScript dependencies built and remediated as an alternative to direct registry access.
Continuous rebuilds
Images rebuilt from source on a regular cadence so newly disclosed vulnerabilities are addressed without manual intervention.
Signed provenance
Cryptographically signed build provenance attached to artefacts, supporting verification throughout the software supply chain.
Preparing for an enterprise security review
A SaaS vendor is midway through a large enterprise sales cycle when the customer's security team requests an SBOM, a CVE remediation SLA and evidence of build provenance for the product's container images. Rather than compiling this manually from scanner exports and spreadsheets, the platform team has already standardised its base images on a hardened, minimal catalogue with attested SBOMs generated at build time. The security lead exports the current SBOM and provenance attestations directly, and points to the documented remediation cadence as evidence of an ongoing patching commitment. The review, which might otherwise have taken weeks of back-and-forth, is closed out in a single exchange, and the sales team is able to move the deal to contract without further security-related delay.
- 1Standardise services on hardened, minimal images with SBOMs generated at build time
- 2Export SBOM and provenance attestations on request rather than reconstructing them
- 3Reference a documented remediation cadence to answer patching questions
Expected outcomes
- Fewer open CVEs to explain or remediate during customer security reviews
- Shorter procurement cycles for enterprise deals that require supply-chain evidence
- Less engineering time spent on base-image patching and dependency triage
- Reduced exposure to malicious or typosquatted packages entering the build pipeline
- Clearer, auditable records of build provenance and software composition
How CyberLane helps
CyberLane advises technology companies on where a secure-by-default image and library strategy fits within an existing build and release pipeline, helping teams define which services to migrate first and what evidence enterprise customers actually need to see. We support the business case for reducing patching toil, plan a proof of concept against representative workloads, and provide implementation oversight — while build tooling and library integration work is carried out by Chainguard or a qualified delivery partner.
- Assessment of current base-image and dependency exposure across build pipelines
- Prioritised migration plan for hardened images by service criticality
- Proof-of-concept scope and success criteria for a pilot workload
- Business case covering reduced remediation and procurement-review effort
- Implementation oversight through rollout and handover to engineering
CyberLane is independent and works on the decision rather than the deployment. Product-specific delivery is coordinated with the vendor or a qualified implementation partner.
