Command view

What this service changes operationally

Glexia supply chain security gives leaders visibility into vendor, software, and partner risk before third-party exposure becomes a business interruption. We combine vendor due diligence, continuous monitoring, contractual controls, SBOM and dependency review, and incident coordination into one risk program.

360Third-party visibility

Critical vendors, fourth parties, software dependencies, data flows, and business services are mapped by risk tier.

SLAAssessment workflow

Questionnaires, evidence review, remediation requests, exceptions, renewals, and approvals follow a defined cadence.

SBOMSoftware supply chain

Open-source, commercial, build pipeline, artifact, and dependency risks are assessed alongside vendor controls.

Operating model

How Glexia runs the service

The engagement is organized into clear delivery lanes so leaders can see what is being assessed, what is changing, and how progress is measured.

Vendor and data-flow tiering

We classify vendors by business criticality, data sensitivity, connectivity, regulatory impact, substitutability, and downstream dependency so review depth matches real exposure.

Critical, high, medium, and low-risk vendor segmentation
Data processing, system access, and integration mapping
Fourth-party and concentration-risk visibility

Evidence-based due diligence

Assessments combine questionnaires with evidence review so teams can validate security claims, contractual requirements, incident history, and remediation commitments.

SOC 2, ISO 27001, penetration test, policy, and insurance evidence review
Security addendum and contractual control recommendations
Exception, remediation, and renewal workflow design

Software supply chain assurance

We review dependency, build, artifact, signing, and release practices to reduce exposure from compromised packages, weak CI/CD controls, and unclear ownership of third-party code.

SBOM, SCA, dependency, and package risk analysis
Build pipeline, artifact signing, and secrets handling review
Vendor incident response coordination and escalation planning

Service FAQ

Supply Chain & Third-Party Risk questions leaders ask

Short answers for scope, operating model, and implementation decisions before a formal engagement begins.

How do you prioritize vendor risk reviews?

We tier vendors by business criticality, data sensitivity, system access, regulatory impact, operational dependency, incident history, and downstream fourth-party exposure. High-impact vendors receive deeper evidence review and more frequent reassessment.

Do you review software supply chain risk?

Yes. We assess dependencies, SBOM practices, package management, build pipelines, secrets handling, artifact signing, release controls, and open-source governance. This complements vendor due diligence by covering the software components that enter production.

Can you help with vendor security questionnaires?

Yes. We can design questionnaires, review evidence, score responses, identify remediation requirements, maintain exception records, and prepare executive summaries. We can also help teams respond to customer security questionnaires with reusable evidence packs.
