Vergate vs Nuclei: which should you use?
#TL;DR
- Nuclei: Free, open-source, template-based scanner from ProjectDiscovery. 10,000+ community templates, extremely fast, massive CVE coverage. CLI-first, built for security teams scanning at scale.
- Vergate: 6 health pillars (security + performance + SEO + AEO + accessibility + monitoring), active DAST via ZAP, 50+ technology detectors, AI fix prompts, MCP server. Free tier, paid from $20/mo.
- Key difference: Nuclei is the fastest way to check thousands of targets against known CVEs. Vergate is the most complete way to understand one site's full health.
#Feature-by-feature comparison

#Choose Vergate if...
- You want one site fully understood — security, performance, SEO, AEO, accessibility, monitoring.
- You want AI fix prompts on every finding.
- You want a health score that combines all dimensions.
- You want scheduling, reporting, and monitoring without pipeline setup.
- You want technology profiling and integration security scanning.
- You want a MCP server for LLM integration.
#Choose Nuclei if...
- You need to scan hundreds or thousands of targets quickly.
- You need broad CVE coverage via community templates.
- You want to write custom detection templates (YAML).
- You're building a security pipeline and need a fast, scriptable scanner.
- You want to integrate with ProjectDiscovery's cloud platform for team workflows.
#The honest take
Nuclei is an incredible tool — 10,000+ community templates covering everything from Log4j to custom misconfigs, running at speeds that make it practical for bug bounty and large-scale scanning. If you need to check many targets against known vulnerabilities fast, Nuclei is the right tool.
Vergate is built for a different question: not "does this target have CVE-2024-XXXX" but "is this site healthy across every dimension that matters for a shipped product." It runs ZAP for active scanning, adds passive checks, then layers on performance, SEO, AEO, accessibility, and monitoring — with AI fix prompts and a composite health score.
They're complementary tools. Use Nuclei for fast, broad vulnerability detection across many targets. Use Vergate for deep, continuous health monitoring of the sites you actually ship.
