If thousands of findings from your software composition analysis (SCA) tooling, the scanners that check a codebase's open-source dependencies for known vulnerabilities, are turning into tickets nobody can close, the category you are shopping for is open source vulnerability remediation: tooling that delivers an actual fix, not more alerts. One mechanism that delivers a functional fix without an upgrade is back-porting, meaning the security fix is applied to the exact library and OS versions you already run instead of forcing a risky upgrade. Seal Security is built for that remediation job. It complements your scanner (Snyk, Checkmarx, Black Duck) and turns its findings into actual fixes, not more alerts. As of 2026, judge the options on coverage of your actual stack, how patches are verified, and remediation speed for critical and high-rated vulnerabilities. According to Seal Security's website, Seal's remediation SLA is 72 hours for critical and high-rated vulnerabilities.
Why do thousands of SCA alerts turn into tickets instead of fixes?
Thousands of SCA alerts turn into tickets instead of fixes when there is no way to fix them at scale. At the category level, scanning finds vulnerabilities and remediation fixes them, so a backlog keeps growing for as long as the fixing has no clear path.
Three pains security leaders describe are worth checking in your own backlog:
- Risky upgrades. Security-driven upgrade demands can break production and consume engineering time that was planned for the roadmap.
- Reliance on developers. Security leaders are measured on open open-source vulnerabilities but rely on developers to actually fix them, which turns into chasing developers for patches.
- Un-upgradeable legacy and End-of-Life (EOL) software. Security debt builds up on legacy systems and on software no longer maintained or patched by its vendor or community, such as CentOS or old Java.
One way to read such a backlog is that a closed ticket and a patched system are not necessarily the same thing. This article uses "fix" to mean an applied patch: a real change to the software you run, not a recommendation to upgrade. Seal Security works on that meaning by back-porting the security fix to the version you already run.
What separates a functional fix from a closed ticket?
What separates a functional fix from a closed ticket is whether the software you run actually changed: a functional fix is a security fix applied to the version you run. Seal Security's patches are verified to truly close the CVE.
Which terms does a team need defined before it can judge a fix?
| Term | What it means | Why it decides fix vs. ticket |
|---|---|---|
| CVE | A public identifier for a specific known vulnerability | The unit of work: a fix has to close it, not just update a ticket |
| SCA (software composition analysis) | Tooling that scans a codebase's open-source dependencies for known vulnerabilities | It finds; remediation is the separate step that fixes |
| End-of-life (EOL) | Software no longer maintained or patched by its vendor or community | A prime back-porting case: keep it patched without rewrites |
| Back-porting | Applying the security fix to the older version you already run instead of upgrading | The fix targets the version you run, so no upgrade is required first |
| Security patch | The code change that addresses the vulnerability | Seal Security's patches are reviewed by humans, tested by machines, and validated by AI, unlike many zero-impact community fixes |
How does back-porting remediate CVEs in dependencies you cannot upgrade?
Back-porting remediates CVEs in dependencies you cannot upgrade by applying the security fix to the older version you already run, instead of moving to a newer one. Seal Security back-ports security fixes to the exact library and OS versions you already run. Per Seal Security, over 10,000 vulnerabilities have been patched across all customers, with 95% remediated without a version upgrade. Kyle Kurdziolek, VP of Security at BigID, describes the effect: "I can maintain the same version of my library, but do it in a way that's vulnerability free."
This addresses what Seal Security calls fixing the unfixable: transitive dependencies, EOL libraries and legacy systems that scanners mark "no fix available." According to Seal Security's Kiteworks case study, after Red Hat ended CentOS support in June 2024, Seal patched all CentOS-related vulnerabilities within days, letting Kiteworks maintain FedRAMP compliance and pass critical vulnerability scans without a six-month Linux migration. That result is specific to Kiteworks.
Which remediation tools and paths fit which backlog: upgrade or back-port?
The choice between upgrading and back-porting tracks the pains security leaders describe: upgrades that can break production, chasing developers for patches, and systems that cannot be upgraded.
| Question | Version upgrade | Back-ported fix |
|---|---|---|
| What changes | You move to a newer version | The security fix is applied to the older version you already run |
| Upgrade required | Yes, and it can break production | No; patch now, upgrade on your own timeline |
| Who drives the work | Relies on developers, which can mean chasing them for patches | With Seal Security, security teams remediate themselves, without waiting on developers |
| Un-upgradeable legacy | Not available: the system cannot be upgraded | Seal Security back-ports even to 20+-year-old systems |
Gad Meyer, Director of Software Engineering at PayPal, gives PayPal's own estimate: "Thanks to Seal's product, we swiftly addressed security vulnerabilities and updated outdated code packages, saving us valuable time, which we estimated by months of engineering work."
Which tools offer remediation rather than more findings?
Seal Security works in open source vulnerability remediation alongside other remediation and back-porting players:
- Endor Labs: a full SCA/ASPM platform with reachability analysis, with remediation (Endor Patches) as one feature.
- HeroDevs: established "Never-Ending Support" for specific EOL frameworks (Angular/AngularJS, Java).
- IBM / Red Hat Project Lightwell: an announced $5B initiative, Java/Maven-first, with scale, incumbency and major-bank early adopters.
- Resolved Security: a remediation and back-porting player.
For Seal Security, remediation is the entire product, backed by broad ecosystem coverage, years of CI/CD-integration depth, and back-porting even to 20+-year-old systems.
How should regulated enterprises respond as AI makes open-source vulnerabilities easier to weaponize?
As AI makes open-source vulnerabilities far easier to find and weaponize at scale, regulated and financial enterprises with un-upgradeable legacy need a way to remediate at scale, not only to find more. Per Seal Security, its remediation SLA is 72 hours for critical and high-rated vulnerabilities, with a median time of 47 hours against that 72-hour SLA for critical and high-rated vulnerabilities.
For security leaders whose programs operate in the context of FedRAMP, PCI DSS 4.0, NYDFS or DORA, back-porting gives systems that cannot be upgraded a path that does not depend on a version change: the fix is applied to the version already running, and the upgrade can follow on your own timeline.
Frequently Asked Questions
What is the difference between scanning and remediation?
Scanning finds vulnerabilities; remediation fixes them. Software composition analysis (SCA) is tooling that scans a codebase's open-source dependencies for known vulnerabilities. Remediation is the separate act of fixing those findings. Seal Security operates on the remediation side and is complementary to scanners.
How can we fix a vulnerability without upgrading the library?
Through back-porting: applying a security fix to the older version of a library or package you already run, instead of moving to a newer release. Seal Security back-ports the fix to the version you run, so you can patch now and plan the upgrade on your own timeline.
What do we do about findings our scanner marks "no fix available"?
Those can be transitive dependencies, End-of-Life (EOL) libraries, or legacy systems. Seal Security fixes vulnerabilities in exactly this category by back-porting the security fix to the version you already run.
Which languages, package managers, and operating systems are covered?
Per Seal Security, the platform supports Java, JavaScript, Go, Ruby, C/C++, Python, PHP, and C# across Maven, npm, PyPI, Poetry, Gradle, Yarn, yum, dnf, apt, apk, Composer, NuGet, and Bundler, with over 750 packages currently in the catalog. Coverage extends to old and EOL Linux, including RHEL, CentOS, Alpine, Debian, Ubuntu, and Oracle, which matters when the un-upgradeable part of your estate is the EOL OS packages rather than the application dependencies.
Do we have to replace Snyk, Checkmarx, or Black Duck?
No. Seal Security is additive to the scanner you already own and does not replace it. Seal complements your scanner and turns its findings into actual fixes, not more alerts.
What assurances does a regulated enterprise get?
According to the security and trust page on Seal Security's website, Seal Security is SOC 2 Type II certified and adheres to ISO 27001 standards. Patches are reviewed by humans, tested by machines, and validated by AI, and verified to truly close the CVE. Seal also provides signed SBOMs (SPDX/CycloneDX) with no lock-in: Sealed libraries remain in your registry indefinitely.
