FAQs

RapidSpike delivers enterprise-grade website and cybersecurity monitoring, and has been trusted by global brands for over a decade. In 2018, we pioneered advanced technology to detect “Magecart” web skimming attacks — a breakthrough that earned recognition at both the European and Global Ecommerce Awards. In 2024, we secured the prestigious InnovateUK Smart Grant to accelerate development of this technology, which we have launched in 2025 as CartShark. Today, we monitor over $40 billion in ecommerce transactions annually, providing critical protection for some of the world’s leading online businesses

Yes — all plans come with a 7-day free trial. You can try CartShark Lite or Plus with no upfront charges. You’ll need to enter your card details during sign-up, but you won’t be charged until after your first full month of usage.

Nope. We believe in clear, accessible pricing. You can sign up and get started without a demo — but if you’d like to see CartShark in action first, we’re happy to schedule one. Otherwise, just sign up, install the tracker, and you’re good to go — all in less than 5 minutes.

No — you can cancel at any time during the trial period, and you won’t be billed. If you continue using the platform after the 7-day trial, billing begins once the trial has ended, based on your projected usage for the month.

Our pricing is usage-based, so you only pay for what you use.

We count how many pageviews our tracker records on your website and assign that number to a bucket (e.g., 0–50,000, 50,000–100,000, etc.). Each bucket has a corresponding monthly rate.

If you’re on the Plus plan, there’s also a charge for each active ScriptSentinel monitor, which are powerful synthetic scripts used to actively test your site.

Lite: Tracks your website for webskimming threats and third party resources, using our lightweight visitor-based tracker.
Plus: Includes everything in Lite, plus automated ScriptSentinel monitoring, which simulates user journeys like checkout flows for deeper security insights and a comprehensive view of your third parties and how they impact your customers.

This is for CartShark Plus customers only – it’s an automated browser that simulates real customer checkouts — essential for catching hidden, time-triggered scripts that standard monitoring can miss. It also gives us a deep-dive into the performance of your third parties, so you can see more clearly into your true site experience.

Just copy and paste a small script onto your website — it only takes a minute. The tracker has minimal performance impact and does not collect any personal or demographic data from your site’s visitors.

Absolutely. All payments are processed securely through Stripe, a trusted industry standard for payment processing.
