Authy vs ScanTower.io

We make the best rated Two-Factor Authentication smartphone app for consumers, a Rest API for developers and a strong authentication platform for the enterprise.

ScanTower.io is an external security monitoring platform that helps teams identify misconfigurations, vulnerabilities, and drift in their public-facing infrastructure. It scans websites and SaaS applications for weak security headers, SSL/TLS issues, exposed files, outdated components, and potential malicious scripts - all without requiring agents, credentials, or internal access. Unlike simple one-off checkers, ScanTower continuously monitors certificate transparency logs, DNS records, and security configuration changes to detect shadow subdomains, unauthorized certificates, and unexpected shifts in your security posture. This prevents the silent regressions that often appear during deployments or infrastructure changes. ScanTower provides clear, actionable reporting built from real-world incident response experience. It highlights what’s wrong, why it matters, and how to fix it - making it easy for developers, security engineers, and SaaS teams to maintain strong baseline security with minimal overhead. Ideal for teams that want practical, automated visibility into the external attack surface without the complexity of enterprise scanners.
