What DNS Spy is
DNS Spy monitors DNS records, domain and SSL expirations, security issues, and look-alike phishing domains. It checks more than 60 record types across authoritative nameservers and keeps a record-level change history. Its Security Center runs more than 40 automated checks and assigns weighted letter grades across account, group, and domain levels. WHOIS and RDAP monitoring tracks changes to registrar, ownership, status, and expiration details. Enterprise Phishing Sentinel looks for typosquatting, homograph, and internationalized domain name attacks using more than 17 techniques, then scores threats from 0 to 100. Provider synchronization works with Cloudflare, DNSimple, DigitalOcean, Bunny DNS, Linode, Vultr, GoDaddy, and Amazon Route 53 through read-only API tokens. Email notifications are available on every plan; Enterprise adds Slack, Discord, PagerDuty, webhooks, and syslog. Personal costs $9 /month for up to 10 domains. Enterprise costs $49 /month for up to 100 domains, with 50-domain expansion packs. Its 7-day trial includes Enterprise features, requires a card up front, and incurs no charge if canceled before it ends.
