SSL Certificate & HTTPS Implementation
An SSL certificate secures information between your site and the user’s browser, keeping sensitive information like login data and payment data safe.

- Utilize Let’s Encrypt or paid SSL services.
- Monitor the validity of your SSL certificate periodically and renew prior to expiration.
Strong Authentication & Access Control
