Quick answer

What is a website risk score?

A website risk score is a single 0-100 rating that summarises a site's health across several passive checks — uptime, SSL certificate, DNS, email security and HTTP security headers. SiteGuard Monitor calculates an explainable score so each point lost maps to a specific issue, making it easy to see overall risk and exactly what to fix.

Five separate checks tell you a lot, but a client just wants one number they can understand. This free website risk score checker rolls uptime, SSL, DNS, email security and headers into a single explainable 0-100 score — with the detail behind every point.

The problem with scattered checks

Uptime in one tool, SSL in another, DNS and email security somewhere else — it's hard to say whether a site is actually in good shape. Clients don't want five dashboards; they want to know if they're safe, in one glance.

  • Separate tools make overall risk hard to judge
  • Issues fall through the cracks between checks
  • Clients struggle to interpret raw technical results

How the risk score works

SiteGuard runs a full passive scan and combines the results into one 0-100 score. It's explainable, not a black box — every deduction is tied to a concrete finding, so you can see precisely why a site scored what it did.

  • One score across all five check categories
  • Each point loss linked to a specific issue
  • Clear severity so you know what to fix first

What the score covers

  • HTTP/HTTPS uptime and reachability
  • SSL certificate validity and expiry
  • DNS records and configuration
  • Email security (SPF and DMARC) and security headers

From a score to a client deliverable

The risk score is the headline of every SiteGuard report. Add a domain, let it monitor continuously, and the score is tracked over time and packaged into branded monthly PDF or HTML reports you can send straight to clients.

  • Score trend tracked over time
  • Headlines your branded monthly client reports
  • Backed by email and Discord alerts when risk rises

Built on passive, read-only checks

Every input to the score comes from passive, read-only inspection — the same lookups a browser or mail server performs. There's no aggressive scanning or intrusive testing, just a safe, repeatable view of a site's posture.

Frequently asked questions

Is the website risk score checker free?
Yes. You can get a risk score for any domain for free with no account. A free SiteGuard account adds continuous monitoring, score history and branded client reports.
How is the risk score calculated?
It combines the results of passive checks across uptime, SSL, DNS, email security and security headers into a single 0-100 value. The score is explainable: every deduction maps to a specific finding rather than a hidden formula.
What counts as a good risk score?
A higher score means fewer and less severe issues. Rather than chasing a perfect number, focus on the specific findings behind any points lost — the breakdown tells you exactly what to address.
Can I show this score to clients?
Yes — it's designed for that. The score and its explanation are the centrepiece of SiteGuard's branded monthly PDF and HTML reports, so clients get one clear number plus the supporting detail.
Does the scan run anything intrusive?
No. The score is built entirely from passive, read-only checks — the same kind of lookups a browser or mail server performs. Nothing intrusive is run against the site.
Will the score update over time?
With monitoring enabled, yes. SiteGuard rescans on a schedule, tracks the score's trend and alerts you by email and Discord when risk increases.
