E-skimming & Magecart
Malicious code slipped into your checkout copies card details as customers type — often hiding inside a trusted‑looking script for weeks.
Retail & E-Commerce
Your storefront never closes. Neither do the attacks.
Every checkout is a target. We stop the e‑skimming that steals card data off your pages, protect cardholder information, get you PCI DSS compliant, and keep watch through the peak seasons when downtime hurts most.

The threat landscape
Where e-commerce gets hit
An online store is exposed to everyone on the internet, all the time — and attackers have a well‑worn playbook for turning that exposure into stolen cards and drained accounts.
Cardholder data exposure
Payment data is the prize. A breach means fraud, forensic costs, card‑brand fines, and the kind of headline that erodes customer trust fast.
Account takeover
Attackers use stolen passwords and automated credential stuffing to hijack customer accounts — draining loyalty points and saved cards.
Bots & fraud
Automated bots scrape prices, hoard inventory, test stolen cards, and commit fraud at scale — distorting your business and your data.
Peak-season attacks
Black Friday and the holidays are prime time for attackers — downtime is costliest and malicious activity hides easily in the traffic surge.
Third-party script risk
Every analytics, chat, and payment script is code you didn’t write running on your site. Compromise one vendor, and your checkout is exposed.
24/7/365
Your store is always open — to customers and attackers alike
A physical shop locks its doors at night. Your online storefront never does. It sits exposed to the entire internet every hour of every day, which means the probing, the fraud attempts, and the skimming never stop either. Security that only works business hours isn’t security — it has to watch whenever your store is open, which is always.
The core challenge
The attack that happens in the browser, not your server
Most retailers picture a breach as someone breaking into their servers. But e‑skimming happens somewhere you may not be watching at all — in the customer’s browser, on your checkout page, inside the scripts you load to run it.
Your own servers can be perfectly locked down while a compromised third‑party script quietly lifts every card number entered. Defending the modern storefront means guarding the client side too — knowing exactly what runs on your payment pages and catching the moment something changes.
Server side — what you guard
Your databases, application, and infrastructure. Important to secure — and the part most retailers already think about.
Covered · but it’s only half the picture
Client side — where skimmers live
The scripts running in your customer’s browser at checkout. The blind spot — and exactly where card data gets stolen.
The gap · often unmonitored, and PCI now requires it

Retail & e-commerce FAQ
Common questions
What is e-skimming or a Magecart attack?
E‑skimming, often called a Magecart attack, is when an attacker slips malicious code into your checkout page and quietly copies customers’ card details as they type them, sending the data to the attacker. Because it can live inside a legitimate‑looking script, it often runs for weeks before anyone notices. It’s one of the most common and damaging threats in e‑commerce — and defending against it means watching what runs on your payment pages, not just your servers.
Do we really need to be PCI DSS compliant?
If you store, process, or transmit payment card data, then yes. PCI DSS is required by the card brands, and non‑compliance can bring fines, higher processing fees, and liability if you’re breached. The current version, PCI DSS 4.0, also adds specific requirements around the scripts running on your payment pages. We assess where you stand, close the gaps, and get you compliant.
Our busiest season is also when we’re most nervous about attacks. Can you help?
Yes — and that instinct is right. Attackers know peak shopping periods are when downtime hurts most and when unusual activity is easiest to hide in the traffic. We provide 24/7 monitoring that stays sharp through your busiest days, so a spike in fraud, a new skimmer, or an intrusion gets caught while you’re focused on selling.
What is account takeover and how do we stop it?
Account takeover is when attackers use stolen or guessed passwords to break into your customers’ accounts — often through automated credential stuffing — then drain loyalty points, saved payment methods, or personal data. We help you put defenses in place such as multi‑factor authentication, bot detection, and monitoring for the login patterns that signal an attack in progress.
We rely on lots of third-party scripts and plugins. Is that a risk?
It’s one of the biggest in e‑commerce. Every analytics tag, chat widget, and payment script on your site is code you didn’t write running on your pages — and if any of those third parties is compromised, the attacker is now on your checkout too. We help you inventory what runs on your site, monitor it for change, and reduce the exposure that comes with a script‑heavy storefront.
