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

2 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  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.

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

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

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 company targets utilities, mobility, and public sectors with a broad portfolio including communication, applications, data center services, and infrastructure. With over 130 customers and approximately 470 employees, rku.it demonstrates significant market presence and growth potential. Their partner ecosystem and certifications add to their competitive advantage. The business model focuses on long-term partnerships and sector-specific IT expertise. The website content and customer logos reinforce credibility and trust. The absence of detailed WHOIS registrant data is standard for DENIC domains and does not detract from legitimacy.

Security posture

The website enforces HTTPS and uses FriendlyCaptcha to protect forms, indicating good baseline security practices. However, the lack of visible security headers (CSP, HSTS, X-Frame-Options) and no published security or incident response policies suggest areas for improvement. No vulnerabilities or exposed sensitive data were detected in the content. Privacy compliance is strong with clear cookie consent and privacy policy. The security score is good but could be enhanced by implementing recommended headers and publishing a security.txt file.

Recommendations

  1. Implement HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Add a security.txt file to facilitate vulnerability disclosures.
  4. Enhance accessibility features to meet higher standards.
  5. Regularly audit third-party scripts and tracking technologies for security and privacy compliance.

Technical notes

Notes

The website is built on TYPO3 CMS with modern JavaScript libraries including jQuery and Owl Carousel, providing a responsive and interactive user experience. The use of FriendlyCaptcha enhances form security. Performance is moderate with room for optimization. SEO is well addressed with meta tags and Open Graph data. Accessibility is basic but could be improved. Hosting details are not explicitly identified. Overall, the technical stack is stable and suitable for the company's business needs.
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.
