Know about it before your users do.
DNSSnuff Pro monitors your domain estate daily, alerts you the moment anything changes, and keeps a full history of every check. DNS problems don't have to become incidents.
DNS problems don't announce themselves.
A certificate expires. A blacklist listing appears. Someone updates an SPF record and pushes it to the wrong zone. A nameserver change propagates incorrectly to part of the network.
None of these send you an email. None of them show up in your monitoring dashboard. They show up in a support ticket three days later, or in a call from a senior manager asking why emails stopped arriving.
What DNSSnuff watches for you
Daily health checks across all domains
Every domain in your dashboard is checked every 24 hours — automatically. No manual intervention, no scripts to maintain.
Instant change alerts
The moment any check result changes on any domain, you get an email notification. Not a weekly digest. Not a dashboard you have to remember to look at. An alert, immediately, when something changes.
Certificate expiry tracking
DNSSnuff tracks SSL certificate expiry on all monitored domains and alerts you well in advance. No more emergency renewals at 2am.
Blacklist monitoring
Your domain and mail server IPs are checked against 50+ real-time block lists every day. If anything gets listed, you'll know within 24 hours — not three weeks later when someone complains their emails aren't arriving.
DMARC and SPF change detection
Someone updated an SPF record and forgot to tell you. An email marketing platform added itself to your SPF without authorisation. DNSSnuff catches both.
Historical tracking
Every check is stored. When something breaks, you can see exactly when it changed. Correlate a delivery issue with a DNS update from last Tuesday. Know what changed, and when.
Multi-domain dashboard
Manage your entire domain estate from one view. Health scores across all monitored domains at a glance. Drill into any domain for the full 72-check report. Filter by issue severity.
Ideal for:
- Internal domain estate (primary, subdomains, regional domains)
- Subsidiary or brand domains
- Partner domains you're responsible for
- Pre-production and staging environments
Plain-English results
You don't need to be a DNS expert to use DNSSnuff — and neither does the person you're reporting to.
Every failed check includes a specific explanation of what's wrong, why it matters, and what to do about it. Share a report link with a developer, a vendor, or a manager without them needing to decode RFC notation.
Put your domain estate under automated watch.
