Change Detection

Your Site Changed Overnight. Would You Notice?

ScanTower builds a baseline on your first scan. Every scan after that gets compared to it. So you know exactly what changed and where.

  • Visual defacement detection
    Screenshot hashing with adaptive thresholds per site. High-security sites can catch small changes. Busy sites won't get false alarms.
  • Configuration drift alerts
    DNS records, security headers, SSL configuration, WHOIS, hosting provider - any unexpected change triggers an alert.
  • New scripts, ports & subdomains
    A new third-party script, an unexpected open port, or a fresh subdomain in CT logs - flagged the first scan it appears.
  • Full screenshot timeline
    Visual evidence from every scan, with side-by-side before/after comparison when something changes.

Visual Defacement Detection

Every scan fingerprints your homepage screenshot and compares it to the last one. A large visual change triggers an alert, catching defacement and injected content that text-based checks can miss.

Frequently Asked Questions

Do I need to install anything to scan my website?

No. ScanTower scans your website from the outside, exactly the way an attacker sees it. There are no plugins, agents, or code changes required - just enter your URL and results arrive in under 60 seconds.

What security issues does ScanTower detect?

Every scan runs 15+ checks: WordPress core, plugin and theme vulnerabilities, exposed API keys and secrets in your JavaScript, Subresource Integrity failures, card skimmers and malware, rogue subdomains via certificate transparency logs, SSL/TLS problems, missing security headers, DNS security issues, open ports, server misconfigurations like exposed .git and .env files, and visual defacement.

How does ScanTower detect that my site has been compromised?

ScanTower takes a snapshot of your site on the first scan: scripts, headers, DNS records, subdomains, open ports, and how it looks. Every scan after gets compared to it. New malicious scripts, integrity failures on CDN resources, unexpected subdomains, and visual changes all trigger alerts.

Does ScanTower work for non-WordPress websites?

Yes, absolutely. WordPress scanning is just one part. SSL, headers, exposed secrets, SRI, malware, DNS, ports, defacement detection all work on any site. We also have dedicated Microsoft IIS scanning.

How often does ScanTower scan my site?

You choose: hourly, daily, or weekly automated scans depending on your plan. Each scan is compared against your site’s history, so you’re alerted only when something actually changes or a new issue appears.

Is there a free plan?

Yes. You can run an instant scan right now without an account, and the free plan includes ongoing monitoring for one site - no credit card required.

Find Out What's Lurking on Your Website

Your first scan takes 60 seconds and could reveal a leaked key, a vulnerable plugin, or a script you never approved. Free - no credit card required.
