Know What’s End-of-Life Before It Becomes a Problem

S3C (Software Supply Chain Security) identifies software in your environment that is end-of-life, no longer patched, or has active CVEs — so you can fix it before an auditor or attacker does.

Upload a software inventory. Get a prioritized report. Know your risk in minutes.

What S3C Does

Your environment probably has hundreds of software components. Some are end-of-life. Some are unpatched. A few have active CVEs in the National Vulnerability Database. Most organizations don’t know which ones until it’s too late.

S3C fixes that. Run a scanner on your systems, upload the inventory, and within minutes you have a complete picture of what needs attention — organized by severity, not alphabet.

Who It’s For

• Security directors and CISOs who need to know their software risk posture before the next audit or board meeting
• IT managers who inherited an environment and need to understand what’s actually running
• Compliance teams preparing for FedRAMP, SOC 2, CMMC, or ISO 27001 assessments
• Consultants and assessors who perform third-party security reviews for clients

How It Works

1. Scan — Download and run the free scanner script for Mac, Linux, or Windows. It generates a CSV of installed software in under a minute.
2. Upload — Log in to the S3C tool and upload your CSV. Processing starts immediately.
3. Review — Your report shows EOL status, patch availability, and CVE data for every item — with the highest-risk items surfaced first.
4. Act — Use the report to prioritize remediation, update your risk register, or brief leadership on what needs to happen next.

What You Get in the Report

• End-of-life status for every software item in your inventory
• Whether active patches and security updates are still being released
• CVE count and severity from the National Vulnerability Database
• Source citations for every finding — no black-box answers
• Downloadable results for documentation and reporting

The Reference Database

S3C is backed by a continuously updated reference database covering thousands of software products across operating systems, development tools, security software, enterprise applications, and embedded systems. The database is researched and updated around the clock — so your report reflects current EOL and CVE data, not a six-month-old spreadsheet.

Scanner Downloads

The scanner scripts are free, lightweight, and collect only software inventory data — no credentials, no configuration files, no network traffic captured.

• Windows scanner (PowerShell)

Built by a Security Practitioner

S3C was built by Jim McConnell, a converged security consultant with decades of experience in physical security, cybersecurity, and executive protection. It started as an internal tool for client assessments and became a standalone platform because the need was universal: every organization has software risk they can’t see.

S3C is part of a broader effort to make enterprise-grade security thinking accessible to organizations of every size — alongside the Metrics On Demand platform and the converged security book series.
