Frequently Asked Questions
What is HTTPS and why is it important?
HTTPS (HyperText Transfer Protocol Secure) is the secure version of HTTP that uses SSL/TLS encryption to protect data transmitted between a website and its users. It's important for security, SEO rankings, and building user trust, as it encrypts sensitive information and verifies website authenticity.
What is mixed content and why is it dangerous?
Mixed content occurs when an HTTPS website loads resources (images, scripts, stylesheets) over HTTP. This breaks the security of the HTTPS connection and can expose users to man-in-the-middle attacks, content injection, and other security vulnerabilities.
What are security headers and why do I need them?
Security headers are HTTP response headers that help browsers protect users from common web vulnerabilities. They include headers like Content Security Policy (CSP), Strict-Transport-Security (HSTS), X-Frame-Options, and X-Content-Type-Options that prevent attacks like XSS, clickjacking, and MIME sniffing.
How often should I check my SSL certificate?
SSL certificates should be checked regularly. We recommend checking your SSL certificate at least monthly, and definitely before it expires (typically 30-90 days before expiration). You should also check after any server configuration changes or SSL certificate renewals.
What does the security rating mean?
The security rating (A+ to F) indicates the overall security level of your HTTPS/SSL configuration. A+ is excellent security with all best practices implemented, while F indicates critical security issues that need immediate attention. The rating is calculated based on SSL validity, security headers, mixed content issues, and other security factors.
