Plate I — Check types

Every angle of your infrastructure, covered.

Fourteen specialised check types, run from several regions at once, so you see the whole picture rather than one probe's opinion.

Accipiter uptimusNo. 01

HTTP / HTTPS

Uptime, status codes, body assertions and latency for any endpoint — plus a flag when response headers give away end-of-life PHP, Apache, nginx or WordPress.

GET https://api.acme.com/health
200 OK  142 ms  fra1
server: nginx/1.18.0  EOL since 2022-04

Outdated-software detection

Circus listatusNo. 02

Blacklist (DNSBL)

Your sending IPs and domains checked against 50+ blocklists. Know the moment you are listed, and where.

93.184.216.34
zen.spamhaus.org       LISTED  127.0.0.2
b.barracudacentral.org clean
bl.spamcop.net         clean

DNSBL monitoring

Falco cipherinusNo. 03

TLS cipher audit

Accepted protocol versions and cipher suites, with deprecated TLS 1.0/1.1 and weak ciphers flagged before an external scanner finds them.

mail.acme.com:443
TLSv1.3 ok   TLSv1.2 ok
TLSv1.0 accepted — deprecated
DES-CBC3-SHA weak

TLS cipher audit

Milvus interrogansNo. 04

New!

MQL query console

Every job and metric across your fleet, queried with a pipe syntax. Filter, aggregate and chart ad hoc — no SQL, no waiting on a fixed dashboard.

The MQL query language

No. 05 DNS A, AAAA, MX, TXT and CNAME records resolve as expected, from every region. No. 06 SSL / TLS certificates Expiry, validity and chain checks, with alerts well before a cert lapses. No. 07 Email authentication SPF, DKIM and DMARC records validated continuously; policy drift caught early. No. 08 DMARC reports Built in Aggregate report ingestion and analysis, on every plan. No. 09 SMTP / EHLO EHLO negotiation, STARTTLS handshake and advertised capabilities. No. 10 TCP / UDP Reachability and connect time for databases, game servers, anything on a port. No. 11 Port scan nmap-based checks that your firewall exposes what you think it does. No. 12 Page speed TTFB, FCP, LCP and CLS from a real browser; regressions flagged. No. 13 SSH banner Service reachability and unexpected version changes. No. 14 Domain expiry WHOIS-based warnings before a registration lapses. No. 15 Broken links Crawls pages and surfaces 404s and dead anchors.

Plate II — DMARC, included

Most tools sell DMARC as an add-on. We don't.

Standalone DMARC processors charge a separate subscription or skip it entirely. With Seabhac, aggregate report ingestion and analysis is part of every plan — including the free one.

1.Automatic ingestion of RUA reports from Google, Microsoft, Yahoo and every other major mailbox provider.
2.Compliance trends, geographic breakdown of sending sources, per-sender DKIM/SPF results.
3.Spot shadow IT and spoofed senders before they damage your domain reputation.
4.No separate tool or login — it sits alongside your uptime, SSL and DNS checks.
5.One-click AI diagnostic report: a structured summary of your DMARC health to paste into any AI chat for root-cause analysis and DNS fixes.

Plate III — How it works

Set up in minutes.

No agents to install. Seabhac probes your infrastructure from the outside, the way your users experience it.

1.
Observe
Add your endpoints
URLs, domains, IPs or mail servers. Choose the check type, the interval, and which regions to probe from.
2.
Record
The probes go to work
Runners across 12 regions execute your checks continuously and stream results back in real time.
3.
Alert
Hear about it first
Alerts reach Slack, PagerDuty, email or a webhook within 30 seconds of a failure being detected.

Plate IV — Coverage

Twelve probe regions, and growing.

Checks run from several locations at once, which removes false positives and shows you where a problem is, not just that it exists.
