Monitor DNS changes, track domain and SSL certificate expirations, audit TLS security, and detect phishing variants—all in one platform, now with an MCP server that connects Claude, ChatGPT, and AI agents to your DNS data.
DNS Spy is a DNS monitoring service that watches your domains across five critical layers—record changes, WHOIS lifecycle, SSL/TLS security, brand protection, and automated security auditing—so your team gets alerted before problems become incidents.
Real-time alerts when DNS records change across all your domains. Never miss unauthorized modifications or configuration errors.
Track domain registrations, expirations, and registrar changes. Included on all plans to protect your domain portfolio.
Discover and monitor SSL certificates across all your domains. Track expirations, detect weak encryption, and audit TLS security automatically.
Advanced brand protection through automated phishing domain variant detection and monitoring, now with SSL certificate intelligence.
Automated DNS security auditing with 40+ checks across connectivity, performance, resilience, DNS records, SSL/TLS, and expiration. Weighted scoring with letter grades at every level.
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.
