CVEs keep coming, pulling engineers into unplanned maintenance
This is not a backlog you can burn down. With Evergreen, every dependency in your application is monitored, and covered when it reaches end-of-life, whether that is today or two years from now.

Every CVE on an end-of-life package is a project
An engineer needs to assess the exposure, read the upstream fix, backport it to a version it was never written for, test that nothing else breaks, and then ship it. Once open source reaches end-of-life, maintainers stop shipping security patches, so every new CVE against it becomes your team's work rather than an upstream release.
None of this work was planned. It comes out of capacity committed to something else, which you are still accountable for delivering. And as the open source dependency tree grows and CVE volume climbs, so do the interruptions.
What breaks when upstream patches stop

CVE open, no fix
Compliance
No evidence to show

The Problem
The common responses, and why they are not sustainable
Put someone on it permanently
A maintenance rotation makes the work predictable without making it smaller. You have converted an interruption into a standing cost, and the engineer on rotation is not building anything that quarter.
Rely on automated updates
Dependabot and Renovate resolve against what is published. On an end-of-life line there is nothing published above you that carries the fix, so the alert fires and no pull request follows. The tool confirms the exposure and cannot close it.
Generate the fix with AI
Fast, and increasingly common. Independent research finds that nearly half of AI-generated code introduces new vulnerabilities, and an unreviewed patch leaves an open question about who answers for it if it misses the vulnerability or breaks production.
The Solution
Evergreen turns remediation from an interruption into a queue you control
Connect your repositories once
Install the HeroDevs GitHub App across the repositories that make up your application.
Every dependency gets a state
Scanning runs on its own. Every dependency is monitored while supported, and queued for remediation once it reaches end-of-life and a CVE lands.
Replacements arrive as pull requests
One open pull request per dependency, ordered by severity and capped per day. You review and merge on your schedule.
Why HeroDevs?
19M+
package versions tracked
1,000+
vulnerabilities remediated
900+
enterprise customers secured by HeroDevs
We maintained our security posture without compromising our strategic roadmap, all while achieving substantial cost savings compared to a full migration.

One per dependency, ordered by severity and capped per day. The first scan on a repository produces a single pull request rather than a hundred.
No. Those handle dependencies that still have a newer version to move to. Evergreen handles the ones that do not, because the release line is end-of-life.
No. Each one waits for your review. Nothing lands in your repository without someone on your team approving it.
It stays monitored, and HeroDevs starts building. Coverage expands based on what customers are actually running.
HeroDevs opens a bump pull request first, which stays inside the line you already run, then the secured replacement follows once it is merged.
Between five and fifteen percent of dependencies in a typical enterprise application are already end-of-life. The exposure report tells you your own number.
