Security Testing for Online Stores

Find what attackers can see in your web shop — before your customers are affected. Clear findings, practical fixes, no security expertise required.

Where Online Stores Are Most Exposed

Most web shop incidents start with one of these four weaknesses.

Checkout Script Tampering

Malicious JavaScript injected into your checkout can copy card details and customer data as they are typed.

Outdated Plugins and Themes

Stores run on plugins and themes written by others. One outdated component with a known vulnerability is often enough.

Leaked Credentials

Admin, staff and customer passwords exposed in data leaks are reused to log in to your store and your customers' accounts.

Exposed Customer Data

Misconfigured servers, backups and admin panels can reveal orders, addresses and personal data covered by the GDPR.

What We Check in Your Store

One scan covers the parts of your shop attackers look at first.

Storefront and Checkout

Web application testing of your shop pages, checkout flow, forms and third-party scripts.

Admin Panel and Logins

Exposed admin pages, weak authentication and access control flaws in customer and staff accounts.

Platform, Plugins and Themes

Outdated platform versions and components with known vulnerabilities, matched against 200,000+ indexed CVEs.

Hosting and Domains

Forgotten subdomains, open services, certificate problems and server misconfigurations.

Leaked Credentials

Credentials linked to your domain that appear in known data leaks, so you can reset them before they are used.

Your Mobile App

If your shop has an iOS or Android app, we analyse how it stores data and talks to your backend.

Evidence for GDPR, PCI DSS and NIS2

Regulations increasingly ask online businesses to prove they test their security regularly. Skono's reports give you that proof.

GDPR

Article 32 requires a process for regularly testing the security of personal data. Continuous scans and reports give you that process and the records to show it.

PCI DSS

Since March 2025, merchants with a hosted payment page must confirm their site is not vulnerable to malicious scripts. Skono checks your storefront and documents the result.

NIS2

Larger retailers, online marketplaces and suppliers to NIS2-covered companies are asked to show regular security testing. Skono's reports help you answer.

Skono provides security testing and evidence. It does not certify compliance — that decision stays with your organisation, auditor or payment provider.

Online Store Security Questions

Which e-commerce platforms can you scan?

Any web-based store, including WooCommerce, PrestaShop, Magento (Adobe Commerce) and custom-built shops. On hosted platforms such as Shopify, we test what you control: your storefront, theme, custom code, third-party scripts and domains. The platform's own servers are the provider's responsibility.

Will a scan slow down or break my store?

You decide what gets scanned and when. Scans run on the schedule you set, so you can run them outside peak shopping hours or against a staging copy first. We agree on scope with you before the first scan.

Does Skono make my store GDPR compliant?

No tool can do that on its own. GDPR Article 32 requires appropriate security measures, including a process for regularly testing them. Skono gives you that testing process and reports you can keep as evidence.

I use a hosted payment page. What does PCI DSS ask of me?

Since 31 March 2025, merchants using a hosted payment page (SAQ A) must confirm that their site is not susceptible to attacks from scripts that could affect their e-commerce systems. Skono scans your storefront for these weaknesses and documents the results. Your payment provider or assessor decides on compliance.

Does NIS2 apply to my online store?

Usually not for small shops. Croatia's Cybersecurity Act, which implements NIS2, covers medium and large organisations in listed sectors, including online marketplaces. If you are larger, run a marketplace or supply companies that are covered, you may be asked to show regular security testing. Skono's reports help you provide it.

Where is my data stored?

Skono runs on Amazon Web Services in the EU. The platform is built and operated by Netscour Security d.o.o. in Rijeka, Croatia.
