Lumstep vs GHAS
GitHub Advanced Security bundles CodeQL SAST, secret scanning, and Dependabot into one subscription. It is excellent at detection. But detection without automated remediation, without SBOM quality scoring, and without GitLab support still leaves significant gaps for most security teams.
GHAS detects. Lumstep detects and fixes.
If your entire stack is on GitHub and CodeQL's call-graph SAST is your primary need, GHAS is a strong choice. If you need the fix opened as a PR automatically, a quality-graded SBOM, trust scores for your OSS packages, EU infrastructure outside GitHub, or GitLab support - Lumstep fills those gaps.

Deep dives
Lumstep opens the PR. GHAS waits for a human.
When Lumstep finds a vulnerable dependency, the remediation worker calculates the patched version, opens a branch, and creates a pull request - with changelog context included. GHAS raises a Dependabot alert, and Copilot Autofix can suggest SAST fixes in the editor, but automated PR opening for dependency vulnerabilities still relies on Dependabot's standard workflow.
Dep fixes open as PRs. SAST findings create Linear tickets. Secrets trigger alerts.240 alerts vs 7 that need action today.
GHAS surfaces Dependabot alerts ranked by CVSS score. Lumstep filters every finding through the CISA KEV catalog and EPSS probability scores, so your team sees the 7 findings with confirmed exploitation or high exploit probability - not the full 240-alert queue that grows faster than it is resolved.
Your code on EU infrastructure. Not GitHub's.
GHAS runs on GitHub's infrastructure - US-primary, with EU data residency available only for GitHub Enterprise Cloud customers on the EU tenant. Lumstep runs on independent EU infrastructure for every customer from the free tier up. Source archives are processed in-memory and never persisted to disk.
