A free scanner that catches a mistake almost every web team makes eventually: accidentally leaving a real API key or database password visible in a website's code where anyone can copy it.
Best alternatives to ScanTower in 2026
ScanTower is an external website security scanner: it runs 30+ automated checks against a site from the outside, the same way a visitor or an attacker would see it, with no plugin or server access required. It covers WordPress-specific vulnerabilities, exposed API keys and hardcoded credentials (AWS, Google, Stripe, GitHub, SendGrid, and others), malware indicators, SSL/TLS configuration, DNS security, and even visual defacement by comparing full-page screenshots over time. Scans use a real browser rather than a simple HTTP fetch, so JavaScript-rendered content gets checked too. Results include client-ready PDF reports with letter-grade scores, baseline comparison to flag what changed since the last scan, and alerts over email, Slack, Discord, or webhook. There's a free tier (1 site, 15 scans/month) and paid Pro/Agency tiers for managing more sites, plus a completely free, no-registration standalone exposed-secret scanner.
