Website security for e-commerce businesses in the UK: a complete guide
Running an e-commerce business in the UK means handling payment data, personal customer information, and order histories at scale — making it a target for attackers who know exactly what is stored there.
Why e-commerce sites are high-value targets
Payment data is the primary target. Even if you use a third-party payment processor like Stripe, your checkout process can still be compromised through Magecart — attackers injecting malicious JavaScript that reads card details as they are entered.
Customer records are the secondary target. E-commerce databases are regularly extracted through SQL injection and sold in bulk.
Account takeover uses credentials leaked from other breaches to access customer accounts — credential stuffing.
Common vulnerabilities
SQL injection through product search or checkout forms. Cross-site scripting in product reviews. Insecure direct object references in order management. Weak admin authentication. Magecart injection.
How to protect your store
Use a hosted payment solution that keeps card data off your servers. Implement a Content Security Policy header. Enable two-factor authentication on admin accounts. Keep all software updated.
