DNS Spy watches your DNS records from resolvers worldwide, tracks domain and SSL expirations, audits security, and protects your brand from look-alike phishing domains—one platform for personal domains and full MSP portfolios.
DNS monitoring is the continuous watching of your domain's DNS records — from the outside, the way the rest of the internet sees them. A DNS monitoring service queries your authoritative nameservers around the clock, from multiple locations worldwide, and alerts you the moment a record changes, disappears, or falls out of sync between nameservers. When DNS breaks, everything breaks: websites go dark, email stops delivering, and hijacked records silently redirect your traffic.
DNS Spy is DNS monitoring software that goes further than change detection. Every domain you add gets record-level monitoring with full change history, 40+ automated security checks, SSL certificate and domain expiration tracking, and WHOIS change detection. Connect your DNS provider — Cloudflare, Route 53, DNSimple, DigitalOcean, Bunny, Linode, or Vultr — and your complete record inventory imports automatically.
And because domain security is bigger than DNS alone, DNS Spy's Phishing Sentinel extends monitoring into brand protection: detecting look-alike and typosquatting domains targeting your brand, scoring their threat level, and tracking them from discovery to takedown. See it all in action — run a free DNS scan on your domain, no signup required.

Managing DNS at scale brings unique challenges that traditional tools can't solve
By the time you discover unauthorized DNS modifications or configuration errors, your services are already down and customers are affected.
Without WHOIS monitoring, critical domains can expire unexpectedly, causing complete service outages and brand damage.
Expired or misconfigured SSL certificates trigger browser warnings that block visitors and destroy trust. Let's Encrypt renewals fail silently, and across hundreds of domains, it's impossible to track manually.
Cybercriminals register similar domains to impersonate your brand, and you only find out when customers report being scammed.
Troubleshooting without a timeline of DNS and WHOIS changes leaves you flying blind during critical incidents.
Join hundreds of MSPs who trust DNS Spy to protect their clients' critical infrastructure. Start monitoring in under 5 minutes.
