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

1 finding 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

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

mnemonic operates in the cybersecurity sector with a business model focused on managed security services and consulting. Their competitive advantage lies in their 25 years of experience, European leadership, and comprehensive service portfolio. Revenue streams likely include subscription-based managed services, consulting fees, and security product sales. The target customers are medium to large enterprises and government entities. The company has a broad partnership ecosystem, evidenced by trusted clients from various industries. Growth indicators include active event participation and a rich content strategy. The company maintains a strong brand and market presence in Norway and Europe.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and cookie consent implemented. However, it lacks explicit security headers such as Content-Security-Policy and security.txt for vulnerability disclosure. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Incident response services are prominently offered, indicating operational readiness. Compliance with GDPR is evident through privacy policies. The absence of detailed security framework disclosures suggests room for improvement in transparency. Overall, the security posture is strong but could benefit from enhanced header configurations and public vulnerability disclosure.

Recommendations

  1. Implement and publish security headers like Content-Security-Policy and X-Content-Type-Options to enhance browser security.
  2. Create and host a security.txt file to facilitate vulnerability reporting and improve transparency.
  3. Disclose security frameworks or certifications to build trust and demonstrate compliance.
  4. Enhance website performance by optimizing resource loading and reducing script sizes.
  5. Maintain and update privacy and cookie policies regularly to ensure ongoing GDPR compliance.

Technical notes

Notes

The website uses EPiServer CMS, a robust platform for enterprise content management. The tech stack includes modern JavaScript and CSS with responsive design techniques ensuring good mobile optimization. The site loads a variety of CSS and JS chunks, indicating modular architecture. Performance is moderate with room for optimization. Accessibility features such as skip links and ARIA roles are present, supporting usability. No major technical debt or outdated technologies were detected. Hosting provider details are not explicit, but the site uses HTTPS with a valid certificate. Overall, the technical infrastructure supports a professional and secure user experience.
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.
