Something changed on your store this week. It wasn't you.
An app updated itself. A script your reviews widget loads started loading another one. A tag went live that nobody deployed. Our AI agent reads your store from the outside — every script, every request, every tracker that fires before your banner is answered — and compares it against last week. Then our security experts decide which of those changes actually matters to you.

Risk grade
Risk went up this week
Two of the three changes below moved it
New script since Tuesday
Loaded by your reviews app, not by your theme. Nobody deployed anything.
A tracker fired before consent was answered
Present on the homepage and product pages. It was not firing pre-consent last week.
Checkout still hands off to the same place
Same payment provider, same scripts as the version you trusted. 14 days running.
Illustrative report. Free tells you what changed; paid adds whether it matters. A grade describes what we observed, not a prediction about your store.
91.6%
of monitored payment pages served a script they had never served before — inside two weeks.
48%
of scripts were loaded by another script, not by the page's own HTML.
8
median new scripts appearing per page over the same two weeks.
Source: c/side, Client-Side Attack Report, Q3 2026, a 14-day window ending 22 July 2026. Their sample is payment pages they monitor for their own customers, not a census of the web — read it as a strong signal rather than a universal rate. We cite a competitor's number because it is the best public measurement of the thing we are describing.
That 48% is why a one-time audit does not hold. Half the scripts on a payment page were not put there by the page. They were pulled in by another script — which can change what it pulls tomorrow, without anyone editing anything.
Two parts of your store. One way of looking at them.
Same engine, same report, two jobs — because the change that draws a privacy letter and the change that draws a processor notice are the same unanswered question: what is running here?
- Headers, TLS and certificates
- Vulnerable JavaScript, and the vendors behind it
- Which services fire before your consent banner is answered
- Whether a fix held, or the behaviour came back
Every platform — Shopify, WooCommerce, Magento, custom. Two free checkers are live now.
- We walk the path a real shopper takes
- Every script observed on that path
- A record of where your checkout normally hands off — and an alert when that changes
- A retained record across your assessment year
On Shopify or BigCommerce? Their vault. Your doorway. We watch the doorway. The payment form sits inside their PCI-validated environment — but the path your shopper takes to reach it, and the destination they are handed to, are still yours.
This category was built for enterprises. One store could not buy it.
Two kinds of vendor already watch for this. Neither was built for a merchant with one store, and it shows in what they ask of you.
| Script-tag tools | Infrastructure scanners | CyberShield Studio | |
|---|---|---|---|
| How they see your store | A script tag you install on your own page | From the outside, nothing installed | From the outside, nothing installed |
| What they understand | Scripts, consent, payment pages | Subdomains, IPs, certificates, cloud buckets | Both |
| Who it was built for | Enterprises with a compliance function | Enterprises with a security team | A merchant with one store |
| Where pricing starts | Around $415/month, ten-domain minimum | Enterprise contract | Free |
Nothing goes on your payment page
We watch from outside, so there is no script tag to add, no performance risk, and no new vendor on the page that takes card details. That last one is not a preference: under PCI DSS 6.4.3, a security vendor's own tag lands in your scope, and you are the one who has to inventory and authorise it.
AI does the legwork. Experts validate. You make the calls.
A storefront changes constantly and most of those changes are nothing. Raw output would bury you in them.
Start with a free check
Two checkers run on any page right now — no account, no card. One checks how your store is set up; the other shows which services start collecting shopper data before your banner is answered. Then verify your domain and we keep checking, weekly, free.
A check shows you today. The question is next week. App updates, theme edits and new agency work change your store — usually without anyone telling you. See how we watch it or the plans.
Something already landed, and there is a date on it
A processor notice, a privacy demand letter, a remediation backlog with a deadline. A subscription is not what you need first. Bounded engagements with a certified security and PCI professional — we scope you down, do the work, and produce the technical record.
We monitor and report; we do not block attacks, and we do not certify compliance. We are not a QSA or an ASV, and nothing we run satisfies PCI DSS Requirement 11.3.2. Your self-assessment, risk decisions and attestation remain your own.
Questions you probably have
Security, tracking and PCI — because a store draws all three kinds of letter from the same blind spot. Plain English, no jargon dumps.
We watch your store from the outside — the way a malicious attacker and a privacy compliance scanner both read it — and tell you what changed. Two products on one platform. Storefront watches what runs on your store and where customer data goes, including services that fire before your consent banner is answered. Checkout watches the path your shopper takes to payment and retains the record an SAQ A script-attack eligibility review asks for. Each has a free plan. Take either product, both, or a different plan for each — there is no base plan and no minimum.
