Detectify vs Semgrep
Side-by-side comparison of features, pricing, ratings, and alternatives.
Detectify is an application security platform that performs dynamic vulnerability scanning across external attack surfaces, testing domains, IPs, APIs, and applications with payload-based techniques rather than relying solely on static signature matching. Its Surface Monitoring product continuously discovers and maps external assets while testing them for exploitable vulnerabilities. Detectify's API scanning uses Dynamic AI Fuzzing to test REST and GraphQL endpoints, and its Application Scanning performs deep, authenticated DAST testing with AI-powered fuzzing and crawling. A distinctive part of the platform is its Crowdsource network of more than 400 ethical hackers who feed newly discovered vulnerabilities, including many without an assigned CVE, into Detectify's scanner within minutes of research.
Semgrep is a lightweight static analysis engine that lets you write expressive, pattern‑matching rules to locate security vulnerabilities and enforce coding standards across many languages. It runs quickly on local machines or in CI pipelines, giving developers immediate feedback without heavyweight setup. The tool is open source and also offers a hosted SaaS platform for enterprise‑grade reporting, collaboration, and policy management, making it suitable for both individual developers and large security teams.
- Crowdsourced ethical hacker research surfaces vulnerabilities before they get a CVE
- Very fast turnaround from new research to live scanner test
- Combines surface monitoring, API, and application scanning in one platform
- Payload-based testing reduces false positives from static matching
- Highly customizable rule language
- Supports many programming languages
- Fast local execution suitable for CI
- Open source core with free community rules
- Pricing is not published and requires a demo or trial request
- Crowdsource-driven findings mean coverage depends partly on researcher activity
- Best suited to organizations with dedicated security or AppSec staff to act on findings
- Advanced SaaS features require paid subscription
- Rule authoring has a learning curve for beginners
- Limited GUI compared to some commercial SAST products
