Autonomous software, not an automatic intervention

You download the kit, upload it to your hosting and run the steps from its interface. The licence gives wpsuite no access to your site, does not transmit your credentials and does not automatically trigger a technician’s intervention.

How it goes

You sign upYour address and your domain name. You receive the download links — no account, no key.

You drop two files by FTPanalyse.php and kshield-analyse.zip, at the root of your site. Nothing to unzip: it is the only technical step.

You open the page and enter your emailA validation code is sent to you: it opens the scan, which takes two to three minutes on an ordinary site.

You read the reportWhat was found, where, and what it does. In your language, no jargon.

Why a sign-up

Because a detection tool handed out without any control also serves those who write backdoors: they would test their own code on it until it slips through the net. The validation code is sent to a real address, and the number of scans is limited.

It is also why the report names the dangerous files and says what they do, but never how they were spotted.

Get the analysis tool

Enter the site concerned. Download links then arrive by email.

Your email address

The site to analyse

The site the delivery email will be about.

Read exactly which data is sent

What the scan transmits. The scan is free. At the end, its verdict and the address you validated by code are sent to us — even if nothing is detected. If items are found, we receive for each one its digital fingerprint, its size and its location. Never the content of your files, never your database, never your visitors' data — unless you tick the box below.

This information serves one purpose only: improving our detection. It stays with Karbonic Sàrl, hosted in Switzerland, and is passed on to nobody else. You can ask for its deletion at any time.

The paid kit, for its part, transmits nothing. It works on your server and lets nothing out of it.

I have read the above and I agree to the transmission of this information.

I also send a copy of the dangerous files detected, to help the analysis. Optional — we advise against it if your site handles sensitive data.

Expected use.

The scan is meant for those who run the site being analysed. Any use aimed at testing the detection on deliberately planted malicious code will be blocked, and the submitted samples will be kept and analysed.

How it works: Free

Real screenshots from the test environment, with an English interface and some French labels.

A scan on your own hosting

Upload the two supplied files to the site root, open the analysis and verify your email. No WordPress plugin is required.

Technical explanation

analyse.php and kshield-analyse.zip run on the server. Detection does not alter scanned files; the tool does create its own working files and report.

Access to Free through email verification.FR interface

A report to prepare recovery

The report identifies detected items. Keep it to assess recovery with Saver or explain your situation to us.

Technical explanation

With your consent, the verdict and detection metadata are transmitted: hash, size and location. Sending a copy of detected files is a separate, optional choice.

Free

Limits to understand

Free does not clean up, quarantine files or harden WordPress.
No detections does not prove the absence of every infection. A scan cannot guarantee recovery of destroyed files.
