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

Silicon Hill is a prominent student club operating within the Strahov dormitories primarily serving CTU students and other university residents. It provides a broad range of services including network infrastructure management, educational courses, event organization, and community facilities such as a gym and workshop spaces. The club has a strong partnership network with major technology companies and the university itself, positioning it as a key player in the student community ecosystem. Technically, the website employs standard web technologies with JavaScript and CSS but lacks advanced frameworks or CMS. The site is moderately optimized for performance and accessibility but could improve mobile responsiveness and SEO. Security posture is moderate; while CSRF tokens are present, there is no evidence of HTTPS enforcement or security headers in the provided data. The absence of WHOIS data is a concern for domain legitimacy verification, though the detailed and consistent website content suggests a legitimate organization. Privacy and cookie policies are missing, indicating compliance gaps. Overall, the site is functional and professional but would benefit from enhanced security and privacy measures.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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';…

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

The club operates as a non-profit entity focused on student engagement and education within the university dormitory context. Its market position is strong locally, supported by partnerships with CTU and technology firms. Revenue streams likely include membership fees and service fees for facilities. The target audience is university students residing at Strahov, with growth potential through expanded educational offerings and events. The partnership ecosystem is robust, including Autodesk, Cisco, and Microsoft, enhancing credibility and resource access. Operationally, the club manages complex network infrastructure and community services, indicating a mature organizational structure. Strategic observations suggest opportunities to improve digital maturity and compliance to support sustainable growth.

Security posture

The website demonstrates a basic security maturity level with some best practices such as CSRF token usage. However, the lack of visible HTTPS enforcement and security headers exposes potential vulnerabilities to man-in-the-middle attacks and clickjacking. No incident response or security policy information is provided, indicating limited transparency and preparedness. The absence of privacy and cookie policies further exposes compliance risks under GDPR. No known vulnerabilities or malware indicators were detected in the content. Overall, the security posture is adequate for a community site but requires improvements to protect user data and enhance trust.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and enforce secure connections site-wide.
  2. Add essential security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  4. Establish and publicize an incident response plan and security contact channels.
  5. Conduct regular security audits of third-party scripts and server configurations to mitigate vulnerabilities.

Technical notes

Notes

The website uses basic web technologies including JavaScript and CSS with jQuery and a slideshow plugin. There is no evidence of a modern CMS or advanced frameworks. Performance is moderate with some broken image references noted. Mobile optimization and accessibility are basic but could be enhanced. SEO is supported by meta tags but lacks structured data such as JSON-LD or Open Graph tags. Hosting provider details are not discernible from the content. Technical debt is moderate, with opportunities for modernization including responsive design improvements and enhanced security configurations.
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.
