The security platform from findings to fixes.

Lumstep scans your repos for vulnerable dependencies, leaked secrets, and unsafe code. Then handles the prioritization, the fixes, and the pull requests.

One platform built by engineers, for engineering teams. No security expertise, no extra dashboard to check, no sweat.

The problem

Right now, the average team is carrying months of unpatched risk and doesn't know it.

Vulnerabilities don't wait for your next sprint. Every day a known vulnerability sits unpatched in your stack is a day an attacker is reading the same disclosure you haven't gotten to yet. Attack methods multiply fast, especially in the AI era. You don't have to be a target. You just have to be exposed. There's just patched and not patched.

With Lumstep, the fix is a reviewed pull request before any of that starts.
Under the hood

Security that actually ships fixes.

Most security tooling is very good at one thing: handing you a longer list of problems. Different logins, different dashboards, different definitions of "critical" and still nobody merging anything. Lumstep runs the whole stack in the background and hands you the fix, not the homework. Here's exactly what's happening under the hood.

Dependency fixes as PRs
AI · Auto-fix

Lumstep's AI writes the PR. You just click merge.

When a dependency has a known vulnerability, Lumstep finds an upgrade path - weighing the blast radius of version changes and following semver rules. And opens a pull request with the diff and the reasoning. No script to configure, no tool to install.

Software inventory (SBOM)

Know exactly what your code is built on.

A complete inventory of every package, version, and license in your codebase, graded for quality is generated on every scan. Exportable for auditors and compliance teams.

Dependency vulnerabilities (SCA)

Every dependency checked against known vulnerability databases.

Every package in your dependency tree is scanned for known vulnerabilities. Critical findings come with real-world context, whether the vulnerability is being actively exploited and how likely it is to be targeted. So the report tells you what needs fixing now, not just what's technically flagged.

Less noise, not more

Cuts the noise. Surfaces what to fix this sprint.

Most scanners dump hundreds of alerts on you and call it a day. Every finding here is ranked by whether it's actively exploitable in the wild and whether you depend on the package directly. Then surfaces only the handful that are actually worth fixing.

Code vulnerabilities (SAST)

Catches security flaws in the code your team and AI agent write.

Not all risk lives in your dependencies. Your own code gets scanned too for potential security issues and highlights where they occur. For each finding, it points to the relevant code, explains the issue, recommends a fix, and creates a Linear ticket so it doesn't get lost.

SQL injection
auth/login.ts
// from req.body - never sanitized
const q = `SELECT * FROM users
  WHERE email = '${req.body.email}'`;

A trust check for open-source

Every library you ship gets a trust score.

Packages your code depends on get evaluated: maintainer activity, contributors, dependency hygiene, CI setup, and risk signals like single-maintainer projects, license type or binary in repo. High-risk packages are flagged in the report.

Catches it before merge

Block pull requests that drop your security score.

Your repos have a security score. One line in your CI pipeline blocks any pull request that drops the score below your threshold. Risky changes are caught in review, not after they merge.

Leaked passwords & API keys

Scans your code and full git history for leaked credentials.

Scans your working tree and full git history for leaked credentials - API keys, tokens, and passwords - and reports the exact file and line. Where possible, each credential is tested to determine whether it's still active or has already been rotated.

Code health

The code everyone's afraid to touch.

Security isn't the only thing that rots. Lumstep tracks the health of your codebase: dead code nobody calls anymore, functions that have grown too complex to touch safely.
