One Tool, Multiple Methods of Detection

Synthetic Checkout Monitoring
Continuously walks through the critical areas of your website, monitoring absolutely anything, sending data from your website.
Proactively spot hidden vulnerabilities and uncover malicious web-skimming scripts. CartShark builds a safe list of calls made from your website, and then warns you if any new destination hosts appear.
With CartShark, you’re always ahead of the wave.

Live User Monitoring
Catch unauthorised scripts lurking beneath the surface by analysing real customer interactions. CartShark then collects information about where visitor data is being sent.
Gain actionable insights, identify unusual patterns and nip potential threats in the bud before they cause damage.
If a malicious destination is added to your website, CartShark will alert you.

Third Party Tag Monitoring
Marketing plugins, live chat, and many more – external scripts are often exploited as entry points for web-skimming attacks. Track and manage these “phishy” third-party scripts to avoid vulnerabilities introduced by external vendors.
Don’t let your site become a feeding frenzy for attackers.

“The tool provides full visibility of all data sources across each of our websites – a problem we previously needed to solve.”
