Checkmarx One - Pros & Cons
Pros
- ✓Consolidates SAST, SCA, IaC, API security, container scanning, and DAST in a single platform, reducing tool sprawl and procurement overhead for enterprise AppSec programs
- ✓AI-assisted remediation generates contextual, language-specific fix suggestions directly in the IDE and PR workflow, helping developers resolve vulnerabilities without deep security expertise
- ✓Strong correlation and prioritization engine reduces noise by linking findings across engines and flagging only exploitable, reachable issues rather than overwhelming developers with raw scanner output
- ✓Deep integration with the developer toolchain — GitHub, GitLab, Bitbucket, Azure DevOps, Jenkins, Jira, VS Code, IntelliJ — keeps security feedback inside existing workflows
- ✓Backed by Checkmarx's mature SAST engine with broad language coverage (35+ languages and frameworks) and a long track record in regulated industries like finance, healthcare, and government
- ✓Includes capabilities to scan AI-generated code and govern usage of AI coding assistants, addressing an emerging risk category that newer point tools often miss
Cons
- ✗Enterprise-only pricing with no public tiers, free tier, or self-serve onboarding makes it inaccessible for startups, small teams, and individual developers
- ✗Initial configuration, policy tuning, and integration into existing CI/CD pipelines can be time-consuming and typically requires professional services or dedicated AppSec engineers
- ✗Scan times on large monorepos can be lengthy compared to lighter-weight SAST tools, which can create friction in fast-moving CI pipelines if not tuned carefully
- ✗Despite improved correlation, SAST engines still produce false positives that require triage, and the AI assistant's fix suggestions need human review before being merged
- ✗User interface and reporting, while comprehensive, can feel dense and overwhelming for first-time users and small teams who don't need the full enterprise feature set
Arcjet - Pros & Cons
Pros
- ✓Security policy lives in code, reviewable in pull requests
- ✓Low latency thanks to in-process WebAssembly execution
- ✓First-class primitives for AI-specific risks (prompt injection, PII, spend)
- ✓Generous free tier suitable for early-stage startups
- ✓Strong DX for Next.js and edge/serverless runtimes
Cons
- ✗Library model means each app/service needs the SDK integrated
- ✗Not a drop-in replacement for a full CDN-level WAF
- ✗Smaller IP/bot dataset than incumbents like Cloudflare or Akamai
- ✗Newer product — fewer compliance certifications than legacy WAFs
- ✗No MCP surface yet for agent-driven security operations
