Troja vs. CyScan.io: recon tool vs. fix-it scanner
CyScan.io is a free attack-surface recon scanner — endpoints, subdomains, fuzzing, screenshots. Troja is a fix-and-ship scanner with AI fixes, AEO and deep-stack scans.
Short version: CyScan.io is a free attack-surface / URL recon scanner — excellent for mapping endpoints, subdomains and assets. Troja is a fix-and-ship scanner: security + SEO + AEO with copy-paste AI fix prompts, connected deep-stack scans and monitoring. They solve different jobs, and they work well together.
What is CyScan.io?
CyScan.io (cyscan.io) is a free "cyber URL scanner" aimed at security researchers and developers. It does endpoint discovery, passive-DNS subdomain enumeration (via crt.sh, CertSpotter and HackerTarget), directory fuzzing, redirect-chain analysis, asset/performance waterfalls with CDN detection, tech-stack detection and multi-device screenshots. It's 100% free, no registration — but by its own admission it isn't a full-stack vulnerability scanner.

Where CyScan.io is strong
CyScan.io is one of the best free recon tools around. Its passive-DNS subdomain enumeration, directory fuzzing and multi-device screenshots are genuinely useful for mapping an attack surface or comparing environments — and there's no signup or paywall. If your job is reconnaissance, it does it well.
Where Troja goes further
CyScan.io stops at mapping; Troja is built to fix. It scores SEO and AEO, prioritizes findings by severity, and writes a copy-paste AI fix prompt for each one. It scans the stack behind the page via connectors, re-tests fixes, and monitors for regressions — none of which is CyScan.io's purpose.
Which should you choose?
- You want free attack-surface recon (subdomains, endpoints, screenshots) → CyScan.io.
- You want to scan, prioritize and fix security + SEO + AEO with AI → Troja.
- Best of both: map with CyScan.io, then fix with Troja.

Frequently asked questions

What is CyScan.io best for?
Attack-surface mapping and recon: endpoint discovery, passive-DNS subdomain enumeration (crt.sh, CertSpotter, HackerTarget), directory fuzzing, redirect-chain analysis, tech detection and multi-device screenshots. By its own description it isn't a full-stack vulnerability scanner.
Does CyScan.io give AI fix prompts, SEO or AEO scoring?
No. CyScan.io maps and analyzes; it doesn't score SEO/AEO, prioritize remediation or generate AI fix prompts. Troja does all three and hands you a paste-ready fix per finding.
Can I use CyScan.io and Troja together?
Absolutely — they're complementary. Use CyScan.io to map your attack surface and discover subdomains/endpoints for free, then run Troja to scan, prioritize and fix what matters with AI prompts.
