Security Posture Analysis
Comprehensive Security Assessment
The website employs HTTPS with a valid SSL certificate and uses a GDPR-compliant cookie consent plugin, indicating awareness of privacy and security best practices. However, no explicit security headers were detected in the HTML content, and there is no public incident response or vulnerability disclosure policy. The contact form collects personal data but appears to be secured via standard WordPress mechanisms. The absence of exposed sensitive data and use of updated WordPress and theme versions reduce risk. Recommendations include adding security headers, publishing incident response contacts, and implementing a security.txt file to enhance transparency and readiness.
Strategic Recommendations
Priority Actions for Security Improvement
Implement HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen defense against common web attacks.
