Magecart & web skimming
A single line of injected JavaScript can quietly steal every card entered at checkout. We monitor client-side scripts and integrity so skimmers are caught the moment they appear.
Retail & E-commerce
Keep the checkout open and the cards safe.
Retailers live and die by uptime and trust. A skimmer on your checkout page, a card-fraud wave, or a Black Friday DDoS can vaporize a season's revenue in hours. S-Security protects your POS, storefront, and payment flows — and keeps you PCI-DSS compliant — so customers buy with confidence.
Threat landscape
Where retail gets hit
High transaction volume, seasonal peaks, and sprawling third-party code make retail one of the most actively exploited sectors.
POS malware
Point-of-sale terminals are prime targets for memory-scraping malware. We harden and monitor POS environments to catch the RAM-scraping tooling before cards leak.
Seasonal DDoS
Attackers time floods to your busiest hours, holding revenue hostage. Always-on DDoS defense absorbs the surge so your storefront stays fast when it matters most.
Card fraud & testing
Bots run stolen cards through your checkout to validate them. Behavioral monitoring detects card-testing bursts and chokes them off before chargebacks pile up.
Supply-chain & plugin risk
Every theme, plugin, and pixel on your store is attack surface. We track third-party dependencies and flag the compromised components attackers love to hijack.
Account takeover & loyalty fraud
Credential stuffing drains loyalty points and saved cards from customer accounts. We spot the automated login abuse and protect your shoppers' stored value.
Compliance
PCI-DSS without the panic
Card compliance is non-negotiable for retail. We shrink your scope, prove your controls, and keep the evidence current so assessments stop being annual crises.
- PCI-DSS 4.0 — scoping, segmentation, and the new client-side script and anti-skimming requirements covered continuously.
- SAQ & ROC support — evidence and guidance whether you self-assess or undergo a full Report on Compliance.
- State privacy laws — CCPA/CPRA and equivalent obligations for the customer data your store collects.
- SOC 2 — for retail platforms and partners that need to demonstrate trust to their own customers.

Scenario
A checkout skimmer, killed before a single card leaked
A fast-growing apparel brand installed a marketing plugin that, two updates later, was hijacked to inject a card-skimming script. Our client-side integrity monitoring flagged the unauthorized script the moment it loaded on the checkout page.
We alerted the team, blocked the malicious domain, and rolled back the compromised plugin within the hour — before a single shopper submitted a card to the skimmer. We then locked down third-party script policy across the storefront with a strict content-security configuration.

FAQ
Retail security questions
How do you stop Magecart and checkout skimmers?
We continuously monitor the integrity of client-side scripts on your payment pages, baseline every legitimate script, and alert instantly when an unauthorized one loads or an existing one changes. Combined with strict content-security policy, that catches skimmers in minutes rather than months.
Can you keep our store online during a Black Friday DDoS?
Yes. Always-on DDoS protection absorbs volumetric and application-layer floods at the edge, and our SOC scales monitoring through your peak windows so you keep selling while attackers waste their effort.
Will you help us achieve and maintain PCI-DSS compliance?
Absolutely. We help reduce your cardholder-data scope, implement the controls PCI-DSS 4.0 requires — including the new anti-skimming and script-management mandates — and keep evidence current so SAQ or ROC time is straightforward.
Do you cover both online and in-store POS environments?
Yes. We secure the full retail footprint — e-commerce platforms, payment APIs, and in-store point-of-sale systems — so card data is protected whether the customer taps, swipes, or checks out online.
