Metric Tower review
A focused DNS and domain-change monitor with near-real-time alerts and escalation options.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Metric Tower is a web-based security platform for organizations managing internet-facing domains and assets. It monitors DNS records, nameservers, registrars, WHOIS data, and domain-expiration dates. Domain owners and security teams can use it to identify ownership changes, infrastructure changes, and approaching expirations. Its monitoring model establishes a DNS record baseline, compares later changes against that baseline, classifies severity, and supports configurable expiration-alert thresholds.
The product fits teams that need alerts routed into existing response workflows. Notifications can be sent through email, Slack, PagerDuty, and webhooks, while API access complements the web interface. A free plan is available, and the product also offers a 10-day free trial. On-demand WHOIS refreshes provide a way to request current ownership and registrar information when a review needs more than the regular monitoring cycle. The wider platform also includes vulnerability scanning, infrastructure monitoring, alert escalation, phishing simulation, and security reporting.
Metric Tower’s strongest focus is operational DNS visibility. Per-record-type monitoring toggles help narrow attention to relevant changes, while severity classification adds triage context. CDN-aware suppression for Cloudflare, Akamai, and Fastly is designed to reduce alerts associated with known CDN behavior. Choose Metric Tower if your priority is tracking domain ownership, DNS, nameserver, registrar, and expiration changes with multiple alert destinations. Consider an alternative if you need monitoring centered outside domain and DNS signals, broader platform access than web and API, or CDN-aware handling beyond the providers supported here.
