Semgrep vs Orbis AppSec

Semgrep detects vulnerabilities.
Orbis AppSec fixes them automatically.

Semgrep is excellent for rule-based static analysis. Orbis AppSec focuses on automatically producing security fix pull requests from detected issues. Both are useful — they solve different parts of the problem.

Semgrep

Semgrep is a fast, open-source static analysis tool with a large community rule registry. It excels at custom rule authoring, CI/CD integration, and broad language support. Security teams use it to enforce coding standards and detect known vulnerability patterns at scale.

Best for:

  • Custom rule authoring
  • Enforcing coding standards
  • Large-scale code scanning
  • Security policy as code
F

Orbis AppSec

Orbis AppSec is an AI security scanner that goes beyond detection. When it finds a vulnerability, it generates a production-ready fix and opens a GitHub pull request automatically. Developers get a security fix ready to review and merge — not just an alert to act on.

Best for:

  • Automated fix pull requests
  • Reducing security backlog
  • Developers who want fixes not just alerts
  • Continuous security on every push

What does Orbis AppSec do that Semgrep doesn't?

Orbis AppSec automatically generates production-ready code fixes and opens GitHub pull requests for every vulnerability detected. Semgrep detects issues and surfaces them — remediation is still manual.

Does Orbis AppSec use Semgrep internally?

Orbis AppSec uses a combination of SAST techniques including Semgrep rules as part of its detection pipeline, alongside custom analysis for specific vulnerability classes.

Can I use Semgrep and Orbis AppSec together?

Yes. You can run Semgrep for broad rule-based scanning and use Orbis AppSec to automatically fix the issues Semgrep surfaces. The workflows complement each other.

Does Orbis AppSec support custom rules like Semgrep?

Orbis AppSec uses a built-in rule set optimized for automated fix generation. Semgrep's strength is its extensible rule language and community rule registry. If custom rule authoring is your primary need, Semgrep is the better fit.
