## Frequently Asked Questions

### Should I use ProjectDiscovery Nuclei or OWASP ZAP for automated DAST scanning in 2026?
Choose ProjectDiscovery Nuclei (32.1k stars, MIT, written in Go) for ultra-fast, zero-false-positive detection of 10,000+ known CVEs, cloud misconfigurations, and exposed panels across APIs and subdomains at 1,450 req/s. Choose OWASP ZAP (16.0k stars, Apache-2.0) when you need deep stateful web application crawling, authenticated session handling, AJAX spidering, and active fuzzing of custom business-logic endpoints.

### How do Aqua Trivy and Gitleaks replace commercial Snyk Enterprise seats?
Aqua Trivy (38.5k stars, Apache-2.0) replaces Snyk Container and Snyk IaC by scanning Docker images, Kubernetes manifests, Terraform, and language lockfiles (Generating CycloneDX/SPDX SBOMs) in 1.8 seconds. Pairing Trivy with Gitleaks (30.1k stars, MIT, 0.35s pre-commit secret detection) and Semgrep cuts a 50-developer Snyk Enterprise bill from $4,950/mo ($99/dev) to $180/mo in self-hosted CI runner compute (-96.4%).
