0–100, higher is better. How it is calculated

The Hacking Day (THD'S) is a cybersecurity education platform offering practical workshops and certifications focused on hacking, pentesting, and information security. The website positions itself as a regional leader in Central and South America, providing hands-on training led by experts. The business model revolves around educational services delivered through courses, workshops, and certifications, targeting individuals seeking to enhance their cybersecurity skills. Technically, the website employs a modern tech stack including Bootstrap, jQuery, Owl Carousel, and Google reCAPTCHA, hosted via NameCheap. The site is mobile optimized with good design and navigation, though SEO and accessibility features are basic. No CMS is detected, indicating a custom or static site approach. Security posture is moderate: HTTPS is enforced and reCAPTCHA is used to protect forms, but the absence of DNSSEC and security headers represents gaps. No privacy or cookie policies are present, and no vulnerability disclosure or incident response information is published, which limits compliance and transparency. Overall, the website is professional and functional with moderate trustworthiness. Strategic improvements in privacy compliance, security headers, and transparency would enhance its security posture and user trust.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

10 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet · found on this site
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

THD'S operates in the technology and education sectors, focusing on cybersecurity training. Its competitive advantage lies in practical, expert-led workshops and internationally recognized certifications. The business targets cybersecurity enthusiasts and professionals in Latin America. Revenue streams likely include course fees and certification charges. The company maintains a modest online presence with social media engagement but lacks extensive contact details or formal policies. Growth potential exists through expanded digital marketing and enhanced compliance. Partnerships with educational institutions and private companies support credibility. The business model is straightforward, emphasizing quality training over broad commercial offerings.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, and Google reCAPTCHA protects forms against automated abuse. However, the lack of DNSSEC and absence of key security headers (such as Content Security Policy, HSTS, X-Frame-Options) expose the site to potential risks. No published security policy, incident response contacts, or vulnerability disclosure mechanisms reduce transparency and preparedness. GDPR compliance indicators are missing, and no privacy or cookie policies are provided. These gaps could impact user trust and regulatory compliance. The site should prioritize implementing security headers, DNSSEC, and formal privacy and security policies to improve its security posture.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement essential security headers including Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features and SEO optimization to improve user experience and search visibility.

Technical notes

Notes

The website uses a modern front-end stack with Bootstrap for responsive design, jQuery for DOM manipulation, Owl Carousel for sliders, FontAwesome for icons, and Google reCAPTCHA for bot protection. Hosting is provided by NameCheap, a reputable registrar and hosting provider. The site loads moderate resources and is mobile optimized. No CMS or backend platform is detected, suggesting a custom-built or static site. Performance is moderate with room for optimization. The absence of analytics tools indicates minimal user tracking. Technical debt appears low, but security improvements are needed to align with best practices.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
