About

ScanTower is a cybersecurity company based in United Kingdom working in application security, network security, email security +1 more.

ScanTower is a website security monitoring platform based in the Cotswolds, England. It scans websites from the outside, as an attacker would see them, without requiring plugins, agents or server access. Each scan runs checks for vulnerabilities, malware and card skimmers, exposed secrets and API keys, SSL/TLS configuration, security headers, DNS and email security, open ports, rogue subdomains and visual defacement. The platform compares scans against a site's baseline history and sends alerts when changes or new issues appear. Plans range from a free tier with monitoring for one site to an Agency plan for managing up to 200 websites with team access controls. The company also offers free single-purpose tools, including SSL, IIS, email authentication, cookie, exposed secret and AI crawler checks. The product was created by a security analyst who investigates compromised websites.
