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

The Center for Advanced Internet Studies (CAIS) GmbH operates a professional academic research website focused on digital age internet studies. The site targets researchers and stakeholders interested in internet research and digital society. The business model is that of a specialized research institute, likely non-profit, with a small organizational size and a focus on collaboration, events, and publications. The website is built on WordPress using the Divi theme and several plugins including Yoast SEO and Borlabs Cookie for privacy compliance. The technical infrastructure is modern and supports good SEO and mobile optimization, although accessibility features are basic. Security posture is solid with HTTPS enforced and cookie consent implemented, but lacks advanced security headers and explicit security policies. No privacy policy or terms of service were found, which is a compliance gap. Overall, the website is professional and trustworthy but could improve in privacy and security transparency.

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

6 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 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';…

  2. GDPR outside view

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

    • 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

CAIS positions itself as a niche research center in Germany focusing on internet studies. Its competitive advantage lies in academic collaboration and digital society research. The business model is research-driven, likely funded by grants or public funds. The target audience includes academics, policymakers, and digital society participants. The website's partnership ecosystem includes social media channels on Facebook and X. Growth indicators are not explicit but the use of modern CMS and SEO tools suggests digital maturity. The organization maintains consistent branding and professional content, enhancing credibility.

Security posture

The website demonstrates a moderate to good security maturity level with HTTPS and cookie consent mechanisms in place. However, it lacks explicit security headers such as Content-Security-Policy and does not publish security or incident response policies. No vulnerability disclosure or security.txt files are present. There is no exposed sensitive data or known vulnerable libraries detected. The absence of privacy policy and terms of service documents indicates compliance gaps, especially under GDPR. Incident response readiness and security culture indicators are not visible on the site. Overall, the security posture is adequate but could be improved with better transparency and technical controls.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve GDPR compliance and user trust.
  2. Implement and publish a security policy and incident response contact information to enhance security transparency.
  3. Add security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve technical security posture.
  4. Consider publishing a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website is built on WordPress CMS with the Divi theme and uses common plugins such as Yoast SEO for search engine optimization and Borlabs Cookie for cookie consent management. The tech stack includes jQuery and other JavaScript libraries. Performance is moderate with no evident blocking issues. The site is mobile optimized and uses structured data (JSON-LD) for SEO. Hosting provider details are not explicit. There is some technical debt in the form of missing security headers and incomplete privacy documentation. Modernization opportunities include improving accessibility and security transparency. Technical risks are low but could impact compliance and user trust if not addressed.
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.
