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

Pluggakuten is a Swedish educational platform providing free homework help and discussion forums across a wide range of subjects. It operates as a non-profit service under Mattecentrum, a recognized educational organization in Sweden. The website targets students and learners seeking academic assistance and live help sessions. The platform is well-positioned in the Swedish education sector as a trusted resource for collaborative learning and homework support. Technically, the site uses modern web technologies including React, jQuery, MathJax, and Google Tag Manager, ensuring a responsive and interactive user experience. Privacy and cookie consent mechanisms are robust, reflecting compliance with GDPR standards. Security posture is good with HTTPS enforced and anti-CSRF protections, though additional security headers could enhance protection. The absence of WHOIS data for the exact domain queried suggests a possible subdomain or lookup issue, but the association with Mattecentrum supports legitimacy. Overall, Pluggakuten presents a professional, secure, and user-friendly educational service with moderate technical sophistication and strong privacy compliance.

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

4 findings rated critical or high. Fix these first.

  1. 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

  2. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Unregistered MX Record

      MX record points to unregistered domain: mail

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory
    • High

      Unregistered MX Record

      MX record points to unregistered domain: mail2

      What to do: Remove or fix MX record pointing to unregistered domain

      • RFC 5321 §5.1
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory
      • NIST CM-8: NIST SP 800-53 Rev. 5 CM-8: System Component Inventory
    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

Pluggakuten operates as a free educational forum supported by donations and volunteer efforts, targeting Swedish students across multiple academic disciplines. Its business model focuses on community-driven knowledge sharing and live tutoring sessions, positioning it as a key player in the Swedish non-profit education sector. The platform benefits from its affiliation with Mattecentrum, enhancing credibility and reach. The website integrates with partner educational sites, expanding its ecosystem. While direct revenue streams are not evident, donation links and volunteer engagement indicate sustainable community support. The site’s content quality and navigation support user retention and engagement, critical for its mission. Strategic partnerships and transparent privacy practices further strengthen its market position.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of anti-CSRF tokens, and cookie consent compliance. The presence of security best practices such as session management cookies and privacy-focused analytics tools like Hotjar and Google Analytics is noted. However, the lack of visible security headers like Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the provided content. The absence of a dedicated security policy or incident response contact limits transparency in security governance. Overall, the site maintains a secure environment appropriate for its educational purpose but would benefit from enhanced security header implementation and published security policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the site against common web attacks.
  2. Publish a dedicated security policy page outlining security practices and incident response procedures to improve transparency and trust.
  3. Add a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  4. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

  5. No WHOIS data found for the exact domain queried, possibly due to querying a subdomain.
  6. Use of modern web technologies and analytics tools.

Technical notes

Notes

The website leverages a modern technology stack including React for dynamic UI rendering, jQuery for legacy support, Prism.js for code syntax highlighting, and MathJax for mathematical content rendering. Google Tag Manager and Hotjar are used for analytics and user behavior tracking with privacy considerations. The site appears to be built on an ASP.NET framework, inferred from cookies and session management. Performance is moderate with responsive design and mobile optimization evident. SEO is supported by comprehensive meta tags and Open Graph data. However, no CMS was explicitly detected, suggesting a custom or proprietary solution. Hosting provider details are not available. The technical implementation is solid but could benefit from enhanced security headers and accessibility improvements to reduce technical debt and improve resilience.
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.
