Feature

A CVE drops for a library in your production code. You should know before your customers ask.

The libraries your application actually runs in production are detected and matched against new vulnerabilities daily. Not from your package.json. From what is actually deployed.

How it works

Detect what you actually run

Each scan identifies the libraries your application actually runs in production. React 18.2, Next.js 14.2, jQuery 3.6, Express 4.18. What is deployed, not what is in your repository.

Monitor vulnerability databases daily

NVD, GitHub Advisories, and CISA KEV are checked daily. When a new CVE is published, it is automatically cross-referenced against every library detected in recent scans.

Get alerted when it affects you

If a new vulnerability affects a library detected in your application, you see it in your Security Changelog marked "Affects your system." Not the full NVD firehose. Only what is relevant to your stack.

CVE-2026-YYYYY: XSS in Angular template compiler

An XSS vulnerability in Angular versions 16.x through 17.x. Your application does not use Angular. This is in the industry feed for awareness only.

Detection from the outside

Traditional vulnerability scanners check your dependencies from your repository. Secureless detects library versions from what your production site actually serves. If a hotfix downgrades a library, if your CDN caches an old bundle, or if a dependency gets vendored at an outdated version, the scan catches it because it checks what the browser actually loads.
