Free WordPress Security Check: Test HTTPS, Security Headers, and Performance in Seconds

You’ve got a WordPress site, it’s been running fine for months, and you assume everything is in order. But do you actually know what a browser, or an attacker, sees when they load your site from the outside? Are security headers missing? Did your domain end up on a malware blacklist without you noticing? Is your site loading so slowly on mobile that half your visitors leave before anything even shows up?

The free Website Check from WP Helping Hand gives you an honest answer in seconds, with no login, no plugin install, and no need to hand over any credentials.

What the website security checker actually tests

The check combines five publicly available signals into one overall picture:

  • HTTPS status: is your site running over an encrypted connection?
  • Security headers: are the important protections like Content-Security-Policy or X-Frame-Options in place?
  • WordPress detection: can a WordPress installation, and possibly its version, be identified publicly?
  • Mobile performance: how fast does your site load on a phone, according to Google PageSpeed Insights?
  • Blacklist status: does your domain show up in abuse.ch’s URLhaus malware database?

From these five values, the tool calculates an overall score from 0 to 100, plus one of four grades: Excellent, Good, Needs Improvement, or Critical.

Why “the site works fine” isn’t a security statement

This is the mistake nearly every site owner makes at some point: as long as nothing visibly breaks, everything is assumed to be fine. Missing security headers don’t cause a crash. They just open an extra attack surface that only gets exploited once it’s too late. A low PageSpeed score doesn’t throw an error, it just loses you visitors quietly. And you usually only find out about a blacklist listing when a customer emails you saying their browser is warning them about your site.

None of that shows up from inside the WordPress dashboard. You have to look at it from the outside, the same way a browser or an attacker would.

Why we don’t just scan any website we like

Here’s an important difference between this tool and a lot of other “website scanners” out there: the website check doesn’t run active attack or vulnerability scans against someone else’s server. It only pulls information that’s already public the moment someone opens the URL in a browser: the same data a normal page visit produces anyway. Actively scanning a server you don’t own, without the owner’s consent, sits in a legal grey area that gets treated differently depending on the country. That’s why the tool is built from the ground up to stay on the right side of that line, no matter whose URL gets entered.

How the check works in practice

The flow is deliberately simple:

  1. Enter a URL: the address of the site you want to check.
  2. Add your email address: so we can send you the result and, optionally, so we can reach out if something needs attention.
  3. Wait up to 30 seconds: during this time the tool fetches the site, queries Google PageSpeed Insights, and checks the URLhaus database.
  4. Read the result: an overall score, a grade, and five detail cards.

What your overall score means

Score Grade
90-100 Excellent
70-89 Good
40-69 Needs Improvement
0-39 Critical

There’s one exception: if your domain shows up on the URLhaus blacklist, the overall grade is always set to Critical, regardless of the calculated number. A malware listing outweighs every other individual result, and rightly so.

The most common issues the check turns up

Missing security headers. By far the most common finding. Use the HTTP Security Headers Checker for a detailed breakdown and ready-to-use code, or the CSP Generator to build a Content Security Policy for your site.

WordPress not detected, even though it is WordPress. As explained above: not a bug, and often a sign of good hardening. If you’re not sure whether that was intentional on your end, it’s worth a closer look.

Low performance score. Usual causes: too many plugins, unoptimized images, no caching, an outdated theme. This is exactly the kind of thing I keep an eye on for clients as part of my WordPress maintenance service.

Domain on the blacklist. The most urgent signal of the five. If this shows up for you, talk to someone who knows WordPress security soon, a short consultation call is a good place to start.

Who gets the most out of this check

Site owners weighing up a maintenance plan: the check gives an objective snapshot of where things stand before price or scope even comes up.

Agencies and freelancers taking over a new client project: a fast first read on security and performance health before the real code review starts.

Anyone who’s simply curious: sometimes curiosity alone is enough to surface a problem nobody had bothered to look for.

FAQ

Das willst du wissen

Is the website security checker really free?
Yes, completely. No credit card, no subscription, no hidden costs. You only need an email address so we can send you the result.
Does the tool need login access to my website?
No. The check only uses data any browser already sees when it loads your site: HTTPS status, response headers, publicly visible source code. There's no login, no FTP, no database access involved.
Why isn't my WordPress installation detected, even though I'm sure it's WordPress?
The check looks for publicly visible signals like the generator meta tag or wp-content/wp-json paths. Some security plugins and CDN setups deliberately strip these signals to make a site harder to fingerprint. A 'not detected' result is usually a good sign rather than a bug. It just means our tool (and potential attackers) can't find obvious traces.
Why can the check take up to 30 seconds?
The performance check runs through Google PageSpeed Insights and simulates a real mobile page load, including load time measurement. That takes a few seconds depending on the site. On very heavy pages, the performance score can occasionally come back as 'not available' if the analysis exceeds the time limit.
What happens with my email address?
It's used only to send you the result. We only reach out proactively if you tick the optional consent checkbox and the result flags something worth addressing. See the privacy policy for details.
Can I use this to check a client's or competitor's website?
Technically yes, since it only pulls publicly visible data: the same information any browser gets from a normal page load. For a proper working relationship, though, it's still worth running the check together with the site owner rather than sending it to their inbox unannounced.
What does it mean if my domain is flagged as 'listed'?
It means your domain appears in abuse.ch's URLhaus malware database as a source of malicious software. That's a serious warning sign and should trigger immediate action regardless of the rest of your score, ideally with expert help.
Does this replace a security plugin or a maintenance plan?
No. It's a quick external snapshot, not ongoing monitoring. A security plugin and regular maintenance check continuously and from the inside: file integrity, malware scans, outdated plugin versions. The website check complements that, it doesn't replace it.
