Web Security Best Practices for Mumbai E-Commerce in 2026

Web Security for Mumbai E-Commerce

Mumbai e-commerce sites handle sensitive customer data — payment details, addresses, phone numbers — making them prime targets for cyber attacks. Here are the essential security measures every site needs.

PCI Compliance Basics

• ›Never store raw card numbers: Use a PCI-compliant payment gateway (Razorpay, Stripe) that handles card data directly
• ›Tokenize payment methods: Store only payment tokens, not actual card details
• ›Annual SAQ validation: Complete the Self-Assessment Questionnaire based on your integration type

Runtime Protection

• ›Content Security Policy (CSP): Prevent XSS attacks by whitelisting allowed script sources
• ›Rate limiting: Protect login and checkout endpoints from brute force and scraping attacks
• ›Web Application Firewall (WAF): Block SQL injection, XSS, and common exploit patterns before they reach your app

Data Protection

• ›Encrypt at rest: Use AES-256 for stored customer data
• ›Encrypt in transit: TLS 1.3 everywhere, including internal API calls
• ›Minimal data collection: Only store what you legally need — delete old records regularly
