Medio (4)

  • mediumheaders

    Missing content-security-policy

    Add a Content-Security-Policy header to restrict resource loading

  • mediumheaders

    Missing x-content-type-options

    Add X-Frame-Options: DENY or SAMEORIGIN header

  • mediumrate limits

    No rate limiting detected

    10 rapid requests all succeeded without any rate-limit headers or 429 responses. The site may be vulnerable to abuse.

    Implement rate limiting (e.g., 429 Too Many Requests) to protect against brute-force attacks

Bajo (8)

  • lowdns

    DMARC policy is 'none'

    DMARC is set but policy is 'none' (monitoring only).

    Consider upgrading DMARC policy to 'quarantine' or 'reject'

  • lowheaders

    Missing referrer-policy

    Referrer-Policy is not set. Full URLs may leak to third parties.

    Add Referrer-Policy: strict-origin-when-cross-origin

  • lowheaders

    Missing permissions-policy

    Permissions-Policy is missing.

    Add Permissions-Policy to restrict browser feature access

  • lowheaders

    Missing Cache-Control header

    No Cache-Control header — browser caching is undefined

    Add Cache-Control with appropriate max-age for static and dynamic resources

  • lowheaders

    Content-Type missing charset

    Content-Type header does not specify charset

    Add charset=utf-8 to Content-Type header

  • lowrate limits

    No WAF detected

    No Web Application Firewall (Cloudflare, AWS, Akamai, Vercel, Sucuri, Fastly) was detected in response headers.

    Consider using a WAF to protect against common web attacks (XSS, SQL injection, DDoS)

  • lowrate limits

    No bot protection detected

    No CAPTCHA, challenge page, or bot detection was triggered during rapid requests.

    Consider implementing bot protection (e.g., Cloudflare Turnstile, hCaptcha) for sensitive endpoints

  • lownews mentions

    No press or news presence

    No press pages found on the site and no external news mentions detected

    Create a /news or /press page with company updates — this builds authority and earns links
