HeroDevs
HeroDevs occupies a clear, unglamorous niche -- keeping abandoned open-source software patched and compliant -- and backs it with a concrete, countable track record (1,000+ CVEs remediated, Fortune 500 clients), making it a credible if narrow addition to a vulnerability-management strategy.

A patch-and-support model for EOL open source isn't a new technique, but productizing it at scale with SLAs is a fairly distinct approach.
500+ clients including Google, Microsoft, Capital One, NASA and T-Mobile, with 1,078+ vulnerabilities remediated across named EOL projects.
$125M growth round from PSG Equity and Album VC in 2025 after years of profitable bootstrapped growth.
Fills a real gap in extended security support for abandoned open-source software, but is fundamentally a services/support model rather than a new technology.
Concrete, countable output (1,078+ CVEs remediated across named EOL projects) plus OpenSSF membership are credible efficacy signals.
Open-source end-of-life risk is a permanent and growing enterprise problem as software supply chains age.
Why CISOs Should Care
A CISO stuck running end-of-life open-source components (AngularJS, Bootstrap, Spring Framework, etc.) that can no longer be patched upstream would use HeroDevs for a 14-day CVE SLA and drop-in secured replacements instead of risky emergency migrations.
What Makes It Different
HeroDevs specializes narrowly in maintaining and patching software after its official end-of-life, rather than offering general application security or vulnerability scanning -- a durable-support model few vendors compete on directly.

Editorial Note: Claims vs. Verified Findings
Employee count is estimated (public reporting cites an ~87-person team in 2024). Client-count and CVE-remediation figures are company-reported.
