API queries for package-specific vulnerabilities across multiple ecosystems (npm, PyPI, Maven, Go, etc.). Includes affected version ranges, severity assessments, and ecosystem-specific metadata

Statistical probability scores (0-1 scale) indicating likelihood of active exploitation within 30 days. Complements CVSS technical severity with real-world exploitation intelligence

API and RSS feed access for open-source vulnerability disclosures, affected package versions, CVSS scores, and remediation guidance from repository maintainers

RSS feed monitoring for actively exploited vulnerabilities confirmed by U.S. Cybersecurity & Infrastructure Security Agency. Includes required action deadlines for federal agencies (BOD 22-01 binding operational directive)

Real-time RSS monitoring for new CVE assignments, modifications to existing CVEs, and severity score updates. Enables proactive notification of emerging threats

Standardized license identifiers, full license texts, OSI approval status, and compatibility matrices. Automated license risk classification (permissive, copyleft, proprietary)

Open Source Initiative approved license list with compliance guidance and known compatibility issues

Platform designed for deployment within client infrastructure boundaries. On-premise deployment option maintains sensitive SBOM and operational data under client administrative control. Supports air-gapped environments for maximum security requirements

RESTful API architecture enables integration with existing enterprise systems. Automated workflows via API for scaled SBOM analysis. Web-based interface for manual upload and proof-of-concept scenarios

SBOM upload → Format validation → Component extraction → Vulnerability correlation (API queries) → License analysis → Report generation. Processing typically completes within minutes for standard SBOM files

Full platform deployment within client data center or private cloud. Complete data sovereignty - all processing occurs within client infrastructure. Suitable for organizations with strict data residency requirements or air-gapped environments

Dedicated environment within client's cloud infrastructure (AWS VPC, Azure VNet, GCP VPC). Client maintains control over data location, network security, and access policies

Web-based interface for rapid demonstration and initial SBOM analysis. Suitable for advisory meeting demonstrations and vendor assessment projects. No client infrastructure required for initial evaluation

Role-based access control (RBAC) with granular permissions. Multi-factor authentication (MFA) support. SAML/SSO integration for enterprise identity providers. Audit logging of all user actions and system events

Encryption at rest (AES-256) for stored SBOMs and analysis results. TLS 1.3 for data in transit. Key management options: client-managed keys or hardware security module (HSM) integration

SBOM analysis during vendor selection process provides technical verification of software composition. Supplements security questionnaires with evidence-based component inventory. Identifies vulnerable dependencies before contract execution

Periodic SBOM requests (quarterly/annual) track changes in vendor software composition. Identifies new vulnerabilities in existing vendor products. Documents vendor patch responsiveness and security posture trends

Validates contractual SBOM delivery requirements. Verifies vendor compliance with security baseline requirements. Provides documentation for vendor performance reviews and SLA enforcement

Comprehensive analysis of acquisition target's software composition. Identifies technical debt through legacy dependency analysis. Quantifies remediation costs for vulnerable components in portfolio

Identifies GPL contamination risks and license conflicts. Assesses liability exposure from non-compliant open-source usage. Estimates costs for license remediation or replacement

Maps overlapping dependencies between acquirer and target. Identifies consolidation opportunities and redundant components. Supports post-merger technical integration roadmap

Automated SBOM generation and analysis supports federal software supply chain requirements. NTIA minimum elements validation. Evidence package for government customer compliance

SBOM analysis supports material cybersecurity risk disclosure requirements. Documents vulnerability management processes for regulatory filings. Provides technical evidence for incident response timelines

Medical device manufacturers (FDA premarket cybersecurity guidance), Financial services (FFIEC cybersecurity assessment), Defense contractors (CMMC SBOM requirements)

Access provisioning and initial platform configuration. Upload 2-3 sample SBOMs for validation. Review automated analysis outputs and report formats. Identify any format-specific adjustments needed

Present generated reports to internal stakeholders. Validate report accuracy against known vulnerabilities. Gather feedback on report formatting and content. Assess readiness for client-facing use

Select pilot client for SBOM analysis service. Execute vendor assessment or M&A due diligence project. Document lessons learned and process improvements. Develop repeatable methodology for future engagements

REST API implementation for automated SBOM submission workflows. Batch processing capability for multiple vendor assessments. Integration with existing client CMDB or asset management systems. Automated notification workflows for new vulnerability disclosures

Infrastructure requirements: Application server, database server, API gateway. Network configuration: Outbound HTTPS for API queries (NVD, OSV.dev, etc.). Optional air-gapped mode with offline vulnerability database. Estimated deployment timeline: 2-4 weeks including security review

Platform administration training (4 hours). Report interpretation for consultants (2 hours). Client presentation guidance (2 hours). Advanced features and API usage (4 hours)

Vendor due diligence assessment (per vendor SBOM analysis). M&A technical due diligence (comprehensive software portfolio assessment). Ongoing vendor monitoring (quarterly/annual SBOM review). Compliance documentation support (EO 14028, SEC disclosure)

Discovery phase: Understand client vendor portfolio and risk priorities. Analysis phase: SBOM collection and automated analysis. Delivery phase: Multi-stakeholder report presentation. Follow-up: Remediation tracking and ongoing monitoring recommendations

Quantify time savings vs. manual SBOM review. Document discovered vulnerabilities missed by questionnaires. Showcase compliance documentation efficiency. Compare vendor security postures with evidence-based metrics

Standard SBOM (100-500 components): Processing completes within minutes. Large SBOM (1000+ components): May require several minutes depending on component count. API queries to vulnerability databases occur in parallel for efficiency

Request SBOM as part of vendor security assessment requirements. Reference Executive Order 14028 and industry best practices as justification. Consider SBOM generation tools for vendor software if source/binaries available. Note SBOM absence as vendor risk factor in assessment

Initial assessment: Upon vendor onboarding or contract renewal. Periodic review: Quarterly or annually depending on vendor criticality. Event-driven: Upon major vulnerability disclosure (e.g., Log4j) affecting vendor's technology stack. Software updates: When vendor releases major version changes
