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

SUNET operates as the Swedish University Computer Network, providing essential network and IT infrastructure services to academic and research institutions across Sweden. Established in 1989, it serves as the national research and education network (NREN) for Sweden, focusing on connectivity, cloud services, security, and collaboration tools tailored for the academic sector. The website reflects a professional and consistent brand identity aligned with its mission to support Swedish higher education and research. Technically, the website employs Bootstrap 4 and custom fonts, delivering a responsive and user-friendly experience. However, the absence of advanced security headers and DNSSEC indicates room for improvement in security hardening. The site lacks explicit privacy and cookie policies, which are critical for GDPR compliance, especially given its European user base. From a security perspective, the website is accessible without WAF or security challenges, but it does not demonstrate comprehensive security best practices such as security headers or incident response information. The domain registration is consistent and trustworthy, with a long history and no privacy protection, reinforcing legitimacy. Overall, the site is safe and suitable for general audiences, with no adult or questionable content detected.

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

7 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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  3. 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 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

SUNET holds a strategic position as Sweden's national research and education network, serving universities and research institutions. Its business model is non-commercial, focusing on providing network infrastructure and IT services to the academic sector. The organization benefits from a long-established presence since 1989, indicating stability and trust within its niche. The website targets academic professionals and institutions, emphasizing services like cloud solutions, security, and collaboration. While the site lacks visible certifications or trust badges, its domain age and registrar credibility support its legitimacy. The absence of detailed contact information and privacy policies suggests potential areas for enhancing transparency and user trust.

Security posture

The current security posture of the SUNET website is moderate but incomplete. HTTPS is assumed but not explicitly confirmed in the provided data. DNSSEC is not enabled, which is a recommended security enhancement for domain integrity. No security headers such as Content-Security-Policy, X-Frame-Options, or Strict-Transport-Security were detected, which are important for mitigating common web vulnerabilities. The site lacks published incident response or vulnerability disclosure policies, limiting transparency in security management. No exposed sensitive data or vulnerable libraries were identified in the provided content. Overall, while no critical vulnerabilities are apparent, the site would benefit from implementing standard security best practices and compliance documentation.

Recommendations

  1. Enable DNSSEC on the sunet.se domain to enhance DNS security and prevent spoofing.
  2. Implement and configure essential security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  4. Add incident response and vulnerability disclosure information to improve transparency and user trust.
  5. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.

Technical notes

Notes

The website is built using Bootstrap 4.0.0-beta and custom web fonts (Inter and Akkurat), indicating a modern but not cutting-edge front-end technology stack. The HTML and CSS appear valid and structured, supporting good mobile responsiveness and user experience. Hosting and domain registration are managed by Loopia AB, a reputable Swedish registrar. Performance is moderate, with no explicit indicators of slow loading or technical debt. The absence of a detected CMS suggests a custom or static site architecture. Opportunities exist to modernize the tech stack by upgrading Bootstrap to a stable latest version and integrating advanced SEO and accessibility features. Security technical risks include missing DNSSEC and security headers, which could impact domain and web application security.
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.
