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

Major League Hacking (MLH) operates as the official collegiate hackathon league, providing a comprehensive platform for students and organizers to engage in hackathons globally. The organization offers key services including hackathon event management, job and internship opportunities, educational resources, and community-building events such as Global Hack Week. MLH holds a strong market position as a leading entity in the student hackathon ecosystem, supported by a large, active community and partnerships with major technology companies. The website reflects a mature digital presence with professional design, clear navigation, and extensive content relevant to its target audience of students and tech enthusiasts. Technically, the website employs a modern technology stack including JavaScript frameworks, Google Charts, and multiple analytics and marketing tools such as Facebook Pixel and LinkedIn Insight Tag. It is hosted behind Cloudflare DNS and CDN services, ensuring good performance and availability. The site is mobile-optimized and accessible, with SEO best practices observed through proper meta tags and structured content. The use of Ruby on Rails components is inferred from CSRF tokens and High Voltage gem usage. From a security perspective, MLH enforces HTTPS and uses CSRF tokens to protect forms, indicating a solid baseline security posture. However, the absence of DNSSEC and explicit security headers such as Content Security Policy or HSTS represents areas for improvement. Privacy compliance is partially addressed with a clear privacy policy and terms of service, but the lack of a cookie consent mechanism may pose GDPR compliance risks. No vulnerability disclosure or incident response information is publicly available, suggesting an opportunity to enhance transparency and security culture. Overall, MLH presents a trustworthy and professional online presence with strong business credibility and community trust. Strategic recommendations include enabling DNSSEC, implementing security headers, adding a cookie consent mechanism, and publishing vulnerability disclosure policies to further strengthen security and compliance posture.

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

5 findings rated critical or high. Fix these first.

  1. 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 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';…

  2. GDPR outside view

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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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
  • 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

MLH is positioned as a key player in the education and technology sectors, focusing on student hackathons and developer community engagement. Its business model revolves around event organization, community support, and facilitating career opportunities for students. Revenue streams likely include sponsorships, partnerships, and event-related services. The organization targets collegiate students, hackathon organizers, and tech companies seeking talent. Growth indicators include ongoing partnerships with major tech firms like DigitalOcean and MongoDB, and a robust content strategy with frequent blog updates. The partnership ecosystem enhances MLH's market reach and credibility. Operationally, MLH maintains a professional website with clear navigation and comprehensive resources, supporting its leadership in the hackathon space.

Security posture

MLH demonstrates a mature security posture with HTTPS enforcement and CSRF protection on forms. The domain is registered with privacy protection, which is justified for this type of community organization. No critical vulnerabilities or exposed sensitive data were detected in the website content. However, the absence of DNSSEC and security headers such as CSP and HSTS indicates room for improvement. The lack of a public vulnerability disclosure policy and incident response contact channels limits transparency and may hinder rapid response to security issues. Privacy compliance is partially addressed but could be enhanced with explicit cookie consent mechanisms. Overall, MLH maintains a secure environment appropriate for its business but should adopt additional best practices to mitigate emerging risks.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  4. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting and improve incident response readiness.
  5. Enhance privacy compliance by providing clear data retention policies and user data management options.

Technical notes

Notes

The website is built on a modern technology stack with JavaScript libraries, Google Charts, and analytics tools integrated for performance and user engagement tracking. Hosting via Cloudflare provides CDN and DNS services, contributing to fast load times and availability. The use of Ruby on Rails components is inferred, indicating a robust backend framework. The site is mobile-optimized and accessible, with good SEO practices implemented. Technical debt appears minimal, but the lack of DNSSEC and security headers suggests some modernization opportunities. Overall, the infrastructure supports a high-quality user experience with scalable and maintainable technology choices.
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.
