MSP Domain Monitoring — Manage Client SSL & Domain Certs at Scale

The MSP Certificate Problem

MSPs often manage SSL certificates and domain registrations across dozens — sometimes hundreds — of client environments. Each client may have multiple registrars, different cert authorities, varying renewal cycles, and their own point of contact who needs to be informed when something expires.

Traditional monitoring tools are built for a single organization. They alert one inbox, track one renewal cycle, and assume a single billing relationship. None of that fits how an MSP operates.

DomainCat is built with MSP workflows in mind. You get a single dashboard for all domains across all clients, with per-domain customization for who gets alerted and how. Your team sees everything. Each client only hears about their own domains.

The MSP Workflow in DomainCat

1

Import client domains

Bulk-import domains from a CSV file — one row per domain, with optional label, group, and owner email columns. Onboard an entire client's portfolio in under a minute.

2

Group by client

Create a group for each client. Filter the dashboard to see one client's domains at a time. Export reports per client in CSV, JSON, or PDF.

3

Set per-domain owner emails

Assign a client contact email to each domain. When that domain's SSL cert or registration approaches expiry, the alert goes to the client — not just your inbox.

4

Monitor automatically

DomainCat runs checks on schedule. SSL cert status, WHOIS data, DNS records, and HTTP security headers all update without any manual effort from your team.

MSP-Specific Features

📧

Per-Domain Owner Alerting

Assign a client contact email to any domain. Expiry alerts go directly to that person — without you forwarding anything.

📥

CSV Bulk Import

Import hundreds of domains at once with a simple CSV. Supports domain, label, group, and owner email columns.

👥

Team Member Access

Invite teammates with read or write access. Collaborate on monitoring without sharing your account credentials.

🔗

Webhook & Slack Alerts

Route alerts to Slack, Microsoft Teams, PagerDuty, or any webhook — per-domain if needed, for fine-grained routing.

🔍

DNS Change Detection

Get alerted when DNS records change unexpectedly — nameservers, A records, MX records. Catch hijacking attempts early.

🛡️

HTTP Security Headers

Check HSTS, CSP, X-Frame-Options, and DMARC for every domain. Generate header health reports for client security reviews.
