Stay Supported, Stay Secure
Never-Ending Support from HeroDevs keeps your open source software secure after end-of-life — without migrating.
TRUSTED BY ENTERPRISE
How It Works
Security Patches
A new NES release every time we find, validate, and fix a CVE that affects your version. Continuous coverage — not a one-time backport, not a deadline.
Same-day response for critical issues
Security and application-breaking issues are top priority.
On-Demand EOL Risk Assessment
81,000+ packages have known CVEs and zero fix path. Your SCA flags the vulnerabilities, but our EOL Dataset (EOL DS) tells you which software is dead.

We Give Back to Open Source
When you choose HeroDevs, a portion of every sale goes directly back to the authors and maintainers who built the software your business depends on. We partner with the open source community — not as outsiders, but as original contributors and long-term stewards.
