How to Check if Your Webshop is Actually Secure

A secure website requires more than just an SSL certificate. 

An SSL certificate only encrypts the data in transit between a user and your site. It does not protect the server itself or the data stored on it. To ensure your shop is actually safe, you need to look at your store from top to bottom. Hosting, payment processing, internal access controls, and more.

This blog shows you how to check if your webshop is actually secure. 

Connection Security

The first step in securing your webshop is ensuring the connection between your customer and your server is locked down.

1. TLS 1.3 Requirement: You must confirm your site is using TLS 1.3. In 2026, TLS 1.2 is considered legacy; TLS 1.3 is the industry standard because it is faster and eliminates insecure encryption features (cyphers) that are vulnerable to modern exploits.
2. HTTP Strict Transport Security (HSTS): It is not enough to just have an SSL certificate. You should also implement HSTS. This is a security header that tells a browser to only interact with your site using HTTPS. This is the primary defence against “protocol downgrade attacks,” where a hacker attempts to force a user onto an insecure version of your page to intercept the connection.

Hosting Security

Your hosting provider is the foundation of your store’s security. If the server is not protected, the rest of your security measures won’t matter. When evaluating a host, look for these specific enterprise-grade features:

1. Self-Learning Web Application Firewall (WAF): A basic firewall isn’t enough for e-commerce. You should look for a self-learning WAF that is specifically tuned for shop software. This allows the system to recognise and block complex attacks (like SQL injection and cross-site scripting) by understanding what “normal” traffic looks like for a webshop.
2. DDoS & Bot Mitigation: Your host should provide active traffic scrubbing. In a high-security setup, the system should be able to distinguish between a legitimate “flash sale” traffic spike and a malicious bot attack intended to crash your site.
3. Isolated Instances: Avoid standard shared hosting. Ensure your shop runs in an isolated environment to prevent “cross-site contamination,” where a security breach on a neighbouring website spreads to yours.
4. Specialised Malware Scanning: Look for a host that integrates industry-standard tools like Sansec. This type of server-side scanning specifically targets ‘e-commerce skimmers’; malicious scripts that steal credit card data and often evade regular malware scanners.
5. Rapid Zero-Day Patching: A secure host uses automated systems to roll out platform-wide patches for zero-day vulnerabilities within hours, protecting you before an exploit becomes common knowledge.

Payment & Data Security

Once your connection and server are secure, you need to protect the actual payment data passing through your store. In 2026, handling customer information requires following strict industry standards.

1. PCI DSS v4.0 Compliance: This is the latest global security standard for any business that accepts card payments. Meeting these requirements is complex, so you should ensure your store is built on a PCI-ready infrastructure. A high-quality host will provide an environment that already meets the heavy technical requirements of PCI DSS 4.0, making it much easier for you to pass your own compliance audits.
2. Tokenisation: Your webshop should never actually store or even “touch” full credit card numbers. You should use a payment gateway that supports Tokenisation. This technology replaces sensitive card data with a random “token” (using providers like Stripe, PayPal, or Adyen). Because the actual card data stays with the payment provider and never hits your server, there is nothing for a hacker to steal from your database.

Access and Backups

The final layer of security isn’t about the software itself, but how you and your team access it. Most breaches in 2026 occur because of weak credentials or a lack of recovery options.

1. Multi-Factor Authentication (MFA): A password alone is no longer an acceptable security measure. You should require a secondary factor (like an authenticator app or hardware key) for every admin login.
2. Limit Staff Permissions: Only give people the access they actually need. For example, someone who only writes blog posts doesn’t need access to your customers’ order history or your server’s deep settings. Minimise the damage if one account is compromised by limiting what people can see. 
3. Offsite Backups: Ensure your host takes automatic, encrypted copies of your site and stores them in a separate physical or cloud location. This is critical for recovering from ransomware attacks or server failures.

Security is a continuous process rather than a one-time setup. It is about building multiple layers of protection, from your server configuration to the way your team logs in every day.

Audit these four areas (connection, hosting, payments, and access) to move beyond a basic padlock icon and truly protect your shop against modern threats. Use this checklist to audit your store today and fix any gaps before they become a problem.
