New in 2026 Five technical pillars, one eight-dimension health score:
Website availability Eight-dimension risk score Public status pages Bulk import & exports

Four outcomes your customers can feel

GuardHound watches five technical pillars under the hood: availability, certificates, domain intelligence, digital exposure, and risk scoring. The eight health-score dimensions summarize those checks, so you get clear action instead of a wall of security jargon.

GuardHound domain security coverage

Keep the website available

Website and service checks catch outages, slow responses, and certificate failures. Get alerts when the customer path is at risk, with faster checks available as you grow.

See availability coverage →

Keep business email trusted

SPF, DMARC, DKIM, breach exposure, and sender reputation checks help keep your messages out of spam and make impersonation harder.

Learn about email trust →

Keep the domain under control

Track DNS, registrar, nameserver, SSL, and Certificate Transparency changes that can signal a hijack, forgotten service, or unauthorized certificate.

Learn about domain control →

Catch exposure early

Find lookalike domains, known vulnerabilities, unsafe-browsing flags, and breach exposure before they become a customer-facing incident.

Learn about early exposure →

Five pillars under the hood

Website availability, certificates, domain intelligence, digital exposure, and risk scoring feed the eight dimensions of your 0–100 health score. The score shows what changed; findings show what to fix.

How the score works →

Actionable fixes, not just alerts

Every finding explains why it matters and what to do next. Keep the signal in one place instead of stitching together separate uptime, DNS, and breach tools.

Frequently asked questions

Everything you need to know about GuardHound.

What does GuardHound actually check?
GuardHound watches five technical pillars: website availability, SSL and certificates, domain intelligence, digital exposure, and risk scoring. The score combines eight dimensions: uptime, certificates, DNS, email authentication, breach exposure, vulnerabilities, brand risk, and hosting reputation.
Do I need to install anything?
No. GuardHound is entirely external — it probes your domain from the outside just like an attacker would. There's nothing to install, no agents to deploy, and no code changes needed.
Is the free scan really free?
Yes. You can run a Website Security Checkup for any domain without creating an account or entering a credit card. It gives you an eight-dimension health score and actionable findings. Choose a protection plan when you want ongoing alerts and monitoring.
How is the eight-dimension health score calculated?
Your domain starts at 100 and loses weighted points across eight dimensions: uptime, certificates, DNS, email authentication, breach exposure, vulnerabilities, brand / digital risk, and hosting reputation. Each daily snapshot also records the top contributors so you know exactly what dropped your score. The final number maps to one of three labels: ALL CLEAR, HEADS UP, or UNDER THREAT. Read the full breakdown →
How often does GuardHound check my domain?
Free Checkup includes a daily check. Website & Domain Watch adds daily website and hourly service checks; Business Protection and Pro can run service monitors as fast as every 5 minutes, while Agency goes as fast as every 30 seconds for client portfolios.
Can I cancel or change plans at any time?
Yes. You can upgrade, downgrade, or cancel your plan at any time from the billing section of your dashboard. Changes take effect at the start of your next billing cycle.
