DNS Monitoring
Detect DNS changes before they break.
A wrong DNS record can take your entire site offline, kill your email, or redirect your customers to a phishing page. Pulsewise monitors your A, NS, MX, and TXT records and alerts you within minutes of any change — accidental or malicious.
Start Free TrialDNS failures are catastrophic and immediate
DNS is the phone book of the internet. When it's wrong, nothing works. Your server can be running perfectly, your code can be flawless, your SSL certificate can be valid — but if your DNS records point to the wrong place, none of it matters.
Unlike a server crash that might affect one service, a DNS misconfiguration can take down your website, your email, your API, and every subdomain you own — all at once. And because of DNS caching, the damage persists long after you fix the records.
Common DNS disasters
DNS hijacking
Attackers modify your records to redirect visitors to phishing sites.
Wrong A record after migration
Domain still points to the old, now-empty server.
Deleted MX records
Your entire company stops receiving email.
Broken TXT records
SPF, DKIM, or DMARC records get corrupted — emails land in spam.
See exactly what changed, when, and how
Pulsewise doesn't just tell you something changed — it shows you the exact record, the old value, the new value, and the timestamp. Whether it's an intentional migration or an accidental deletion, you'll have the full picture in seconds.
Every change is stored permanently so you can look back at your DNS history weeks or months later. Perfect for post-incident reviews, compliance audits, or simply understanding how your infrastructure has evolved. Toggle monitoring per record type to control signal-to-noise.
