VulnPilot

Prioritize vulnerabilities using real-world exploit intelligence — not just severity scores.

Runs locally. Your data never leaves your machine.

---

Quick Start

pip install vulnpilot
vulnpilot update-feeds
vulnpilot analyze scan.csv

VulnPilot downloads the latest public threat intelligence, analyzes your Nessus scan locally, and shows what should be remediated first. No API keys required.

---

The problem

Security teams often spend hours manually triaging scan results. Your Nessus export contains thousands of findings. CVSS says hundreds are Critical. The real question — which ones are actively being exploited right now?

VulnPilot answers that question in seconds using real-world exploit data — not just severity scores.

---

Why VulnPilot?

Instead of	VulnPilot
Sorting by CVSS score alone	Uses KEV + EPSS + CVSS composite scoring
Manual triage taking hours	Automated prioritization in seconds
Uploading scans to cloud services	Local-first — data never leaves your machine
Enterprise-only platforms	Community Preview — free and open source

---

  ★ KEV = CISA Known Exploited Vulnerability — highest remediation priority
        based on active exploitation in the wild.

VulnPilot cross-references your findings against three data sources — all processed locally:

Source	What it tells you
CISA KEV	Confirmed exploited in the wild right now
FIRST EPSS	Probability of exploitation in next 30 days
CVSS	Severity context and baseline scoring

Composite score = KEV (40%) + EPSS (35%) + CVSS (15%) + Severity (10%)

Why local-first?

Many organizations prohibit uploading vulnerability scan data to third-party cloud services. VulnPilot performs all analysis locally on your machine.

Usage

# Download latest KEV and EPSS feeds
vulnpilot update-feeds

# Analyze a Nessus CSV export
vulnpilot analyze scan.csv

# Export HTML report
vulnpilot analyze scan.csv --html report.html

# Show top N hosts by aggregate risk
vulnpilot analyze scan.csv --top-hosts 5

# Use local feed files
vulnpilot analyze scan.csv --kev ./kev.json --epss ./epss.csv.gz

# Disable colour output (for CI pipelines)
vulnpilot analyze scan.csv --no-colour

---

HTML Report

Generate a shareable, self-contained HTML report:

vulnpilot analyze scan.csv --html report.html

The report includes:

• Executive summary with KEV and EPSS highlights
• Prioritized findings table with colour-coded risk scores
• Top 10 hosts by aggregate risk with visual score bars
• PatchVex branding and upgrade CTA

---

How scoring works

The scoring algorithm is deterministic, transparent, and fully documented.

Signal	Weight	Source
CISA KEV match	40%	Known exploited in the wild
FIRST EPSS score	35%	Exploitation probability
CVSS base score	15%	Severity context
Scanner risk rating	10%	Nessus severity label

The composite score is intentionally opinionated. Known exploited vulnerabilities receive the greatest weight because active exploitation is a stronger predictor of remediation priority than severity alone. Any KEV finding scores a minimum of 75 regardless of other factors.

The weighting model is intentionally transparent and may evolve based on community feedback and real-world usage.

Note

VulnPilot provides prioritization guidance to assist remediation workflows. Final remediation decisions should always consider asset criticality, business context, exploit mitigations, and organizational risk tolerance.

---

Privacy by design

• Scan data processed entirely on your local machine
• No account required
• No cloud upload, ever
• No telemetry or analytics
• No API keys required
• Works air-gapped after initial feed download
• Open source — inspect every line of code

---

Feed updates

VulnPilot pulls two public datasets:

• CISA KEV — Known Exploited Vulnerabilities catalog (maintained by CISA)
• FIRST EPSS — Exploit Prediction Scoring System (updated daily by FIRST.org)

Feeds are cached at ~/.vulnpilot/feeds/ on your machine. No API keys required.

vulnpilot update-feeds

The GitHub repository also runs an automated daily feed sync via GitHub Actions.
