Here’s why teams that started on Semgrep *land on Checkmarx *
Application Security That Matches Your Devs Velocity
Semgrep’s lightweight, open-source static analysis can leave critical security gaps. Checkmarx delivers deep, end-to-end coverage in an AppSec platform built for scale, speed, and secure development from commit to production
Integrated AppSec. No Silos. No Gaps.
Semgrep misses half your risk surface, while Checkmarx secures human and AI-generated code across every stage of the SDLC -including SAST, SCA, IaC, API, DAST, secrets, containers, and ASPM – all in one platform.
Developer-First Application Security
Catch and fix issues before commit with native IDE, SCMs, and CI/CD integrations, real-time in IDE remediation and AI, and secure code training
Reduce False Positives; Find and Fix Issues Faster
Semgrep’s noise slows teams down. Checkmarx cuts through the clutter and improves the developer experience with up to 90% fewer false positives, reducing remediation time by 30–50%.
Checkmarx vs. Semgrep: full breakdown
| Capability | Checkmarx One | Semgrep |
|---|---|---|
| AppSec Coverage | ✓ WIN SAST, SCA, IaC, API, Container, Supply Chain, ASPM – unified and correlated on a single appsec platform | SAST + Supply Chain (SCA) + Secrets only; gaps elsewhere |
| SAST Accuracy & Depth | ✓ WIN Mature engine, customizable queries, exploitable path, 35+ languages. Advanced AI and correlation | Lightweight, YAML based rules, higher false positives in complex codebases |
| SCA | ✓ WIN Reachability, exploitable path, malicious package detection, license risk, full SBOM support | Supply Chain product available; less mature than dedicated SCA platforms |
| Rule quality | ✓ WIN Curated and maintained by dedicated rule engineering team | Community rules reliant on open source; quality varies, requires internal vetting at scale |
| Application Security Posture Management | ✓ WIN Native ASPM with policy engine, third-party scan ingestion, prioritization, IDE integration | Limited posture management capabilities |
| DAST & Runtime Security | ✓ WIN Native DAST and runtime correlation | Not offered |
| Supply Chain Security | ✓ WIN 420k+ malicious packages, repo health, ChainJacking protection | Dependency scanning; less depth on malicious packages and repo health |
| Container & API Security | ✓ WIN Native support for container scanning and API security | Not offered |
| AI Capabilities | ✓ WIN Real-time remediation in IDEs, triage and safe refactors with suite of AI agents | Emerging AI features; less depth across the platform. |
| Support + Services | ✓ WIN Premium support, AppSec maturity assessment, dedicated TAM | Self-serve and community-led; enterprise support available with paid tiers |
| Reporting & Dashboards | ✓ WIN Application Risk Management with executive-level posture views | Reporting focused on findings; limited executive views |
| Pricing | ✓ WIN Predictable enterprise pricing for the full platform | Free OSS tier; paid tier scales with usage |
| Innovation | ✓ WIN Continuous platform investment across SAST, SCA, ASPM, AI, Software supply chain | Strong SAST innovation; broader platform innovation lags |
| Enterprise Readiness | ✓ WIN Multi-tenant cloud, on-prem, hybrid; deployed at Fortune 100 scale | Cloud and self-hosted options; enterprise governance still maturing |

Why Checkmarx Is Better Than Semgrep
Semgrep was built for developers, not enterprises – Checkmarx is built for both, embedding AppSec directly into the workflow so developers fix faster and stay in flow.
Enterprise Agentic Appsec Platform
Lightweight open-source static analysis tools weren’t built for enterprise risk. When governance, visibility, and compliance matter, Semgrep’s static scans and shallow insights fall short. Checkmarx delivers 100% codebase coverage, 70% faster compliance reporting, analytics, and dashboards built for real enterprise visibility to deliver application security that grows with you instead of slowing you down.

Automated Remediation
Fix once, fix right – with automated remediation across the full code path. Checkmarx One Assist delivers real-time remediation in the IDE, automatically scanning, validating, and fixing insecure AI or developer-written code.

Gaps in rule quality leave your code exposed. Semgrep’s open-source rules lack consistency and enterprise validation, leading to false positives and missed vulnerabilities. Checkmarx takes a different approach—our proprietary research team, Checkmarx Zero, powers the intelligence behind Checkmarx One to deliver high-fidelity results, fewer false positives, and faster time-to-fix.
