Domain Security Monitoring Challenges You Shouldn't Face Alone

Managing DNS at scale brings unique challenges that traditional tools can't solve

DNS changes go unnoticed until it's too late

By the time you discover unauthorized DNS modifications or configuration errors, your services are already down and customers are affected.

Domain expirations catch you off guard

Without WHOIS monitoring, critical domains can expire unexpectedly, causing complete service outages and brand damage.

Phishing variants targeting your brand go undetected

Cybercriminals register similar domains to impersonate your brand, and you only find out when customers report being scammed.

No historical record of DNS and domain changes

Troubleshooting without a timeline of DNS and WHOIS changes leaves you flying blind during critical incidents.

DNS Spy solves all of these. Start your free 7-day trial, no credit card required.

Join hundreds of MSPs who trust DNS Spy to protect their clients' critical infrastructure. Start monitoring in under 5 minutes.

Frequently Asked Questions

Everything you need to know about DNS Spy

Who is DNS Spy meant for?
DNS Spy is DNS monitoring software built for teams that cannot afford to find out about a DNS change after the damage is done.

You get full access to all Enterprise features for 7 days—no credit card required. This includes DNS monitoring, WHOIS tracking, and Phishing Sentinel brand protection.

Phishing Sentinel is our Enterprise-only brand protection feature that automatically discovers and monitors domain variants that could be used for phishing attacks against your brand.
