EASM for Ecommerce: Protect Your Online Store
Why ecommerce has an outsized attack surface
An online store is one of the most exposed businesses on the internet. Beyond the main storefront, there is a checkout flow, payment integrations, an admin backend, third-party plugins, a CDN, image and asset hosts, and a rotating cast of marketing subdomains for campaigns and landing pages. Every one of these is reachable from the public internet, and every integration you add expands the surface.
Attackers know retailers hold card data and customer accounts, so ecommerce is a high-value, heavily probed target. The common failures are mundane: an expired TLS certificate on a payment subdomain, an exposed admin panel, a forgotten campaign site running an outdated CMS with a known vulnerability. Any of these can lead to card skimming (Magecart-style attacks), account takeover, or a breach that damages trust at the worst possible moment.
What EASM watches for an online store
- Checkout and payment paths — valid, strong TLS on every host that touches payment data, so connections stay encrypted and trusted.
- Exposed admin and staging environments — store backends and test sites that should never be publicly reachable.
- Forgotten campaign subdomains — seasonal and promotional sites left live and unpatched after a campaign ends.
- Security headers — protections like CSP and HSTS that reduce the risk of injected skimming scripts and downgrade attacks.
- Known vulnerabilities in your storefront platform, plugins, and public services.
- Email authentication — SPF, DKIM, and DMARC gaps that let attackers spoof your order confirmations and phish customers.
How SurfaceLoop handles this
SurfaceLoop continuously checks TLS certificate validity and configuration across every host it discovers under your domain — so an expiring certificate on a checkout or payment subdomain is caught before customers hit a browser warning.

You do not need to be a PCI DSS expert to keep your store’s external hygiene in good shape. SurfaceLoop discovers the assets around your store, checks them continuously, and explains each finding in plain English with a clear fix. Because it monitors constantly, it catches the new exposures that appear whenever you install a plugin, add an integration, or launch a seasonal campaign — exactly when stores tend to move fast and miss things.
It’s one flat plan at £149/mo covering your store and the domains around it, with no security specialist required — and it starts with a 14-day free trial on your own domains.
Frequently asked questions
- Does SurfaceLoop make my store PCI DSS compliant? +
- SurfaceLoop is not a formal PCI compliance certification service, but it directly supports PCI-relevant hygiene: it continuously checks TLS on payment paths, flags exposed admin interfaces, missing security headers, and known vulnerabilities. This external visibility helps you maintain the secure configuration PCI DSS expects.
- Can EASM help prevent card skimming attacks? +
- It helps reduce the risk. Skimming (Magecart) attacks often exploit exposed admin panels, outdated plugins, or missing security headers like Content-Security-Policy. SurfaceLoop surfaces these weaknesses across your storefront and subdomains so you can close the entry points attackers use to inject skimming scripts.
- What about the marketing subdomains my agency creates? +
- Those are a common blind spot. SurfaceLoop's automated discovery finds campaign and landing-page subdomains under your domain -- including ones created by an agency and never decommissioned -- and monitors them for expired certificates and vulnerabilities alongside your main store.
- How much does it cost for an online store? +
- SurfaceLoop is one flat plan at £149/mo with everything included -- your main store plus the campaign and marketing domains around it. Pricing is published openly with no per-target metering, so costs stay predictable as you add stores. It starts with a 14-day free trial, no card details.
