Run web, API, code, dependency, cloud, AI, and internal-network assessments from one queue with unified findings, evidence, remediation, and audit output.
Supply chain
Letter grade
Heuristic A–F verdict derived from severity, reachability, and evidence quality.
Findings, reports, dashboards, exports, integrations, and retests all read from the same normalized record.
Pencheff favors repeatable checks, then uses AI for triage, enrichment, orchestration, and remediation where it adds signal.
Coverage
What does Letter grade test?
- Heuristic A–F verdict derived from severity, reachability, and evidence quality.
- This page is part of Platform under Deliverables.
- It links back into the broader a complete adversarial security platform experience.
- OSV.dev, NVD 2.0, GitHub Advisory Database, RustSec, GoVulnDB, EPSS, CISA KEV, and SSVC enrichment.
- Manifest support for npm, PyPI, Go modules, Cargo, Ruby, Composer, Maven, OS packages, and container packages.
- SPDX 2.3 and CycloneDX 1.5 SBOM generation with optional Syft enrichment.
- Reachability annotation that separates exploited, reachable, present, and unknown risk.
- License policy checks and deterministic version-bump remediation for eligible dependencies.
Execution
How does Pencheff run this?
- Parse repository manifests, lockfiles, or container package inventories.
- Resolve packages to advisories, fixed versions, package URLs, and known exploitation signals.
- Annotate reachability from imports, call paths, runtime evidence, or scanner context.
- Generate SBOM output and link component rows back to findings.
- Prioritize remediation by exploitability, reachability, business criticality, and compliance impact.
Evidence
What evidence does this produce?
- Package name, ecosystem, installed version, fixed version, advisory id, CVSS, EPSS, KEV, and SSVC.
- SBOM component records with PURL, supplier, version, license, and dependency relationships.
- Reachability state, import evidence, or reason the vulnerable component is currently only present.
- Audit appendix output for procurement, compliance, and release records.
Controls
How is this kept safe to run?
- Dependency risk is not sorted by CVSS alone; operational signals influence priority.
- SBOM generation is repeatable and latest-generation output replaces stale records.
- License and vulnerability policy can be used as release-gate input.
- Version-bump fixes are deterministic when advisory metadata supports them.

FAQ
Common questions
- What is a security letter grade?
- A letter grade (A–F) is a single risk-score that aggregates all open findings weighted by severity, exploitability, and compliance impact. It gives executives and security teams an immediate signal of application risk posture without reading a full technical report.
- How is the Pencheff security letter grade calculated?
- The grade reflects the current verified finding set: critical and high-severity confirmed findings have the most weight. Informational issues and suppressed findings do not affect the grade. The score updates automatically after each scan or remediation.
- Can I track the security grade over time?
- Yes. Pencheff shows grade history across all scans for each target, so you can demonstrate continuous improvement to auditors, customers, and boards — and identify regressions introduced by new deployments.
