Scanned

3 of 7 checks could not complete. The site may be unreachable or blocking automated scans, so the results below cover only what could be checked. Try a rescan later.

NIS2 and GDPR posture

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

2 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

KLIMAK operates primarily in the energy and real estate sectors, providing integrated technical solutions for building comfort and efficiency. Their business model combines engineering, manufacturing, installation, and after-sales services, serving a large client base including industrial, commercial, and residential customers. The company leverages certifications and awards to enhance credibility and maintains a strong partnership ecosystem, including a dedicated e-shop subsidiary. Their digital strategy includes multilingual content and SEO optimization, positioning them competitively in the regional market. Growth indicators include recent project references and active recruitment efforts.

Security posture

The website employs HTTPS with a good SSL configuration and uses security plugins such as Wordfence, indicating proactive security management. Cookie consent and GDPR compliance are well implemented via Complianz. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests gaps in transparency and readiness. No critical vulnerabilities or exposed sensitive data were detected in the site content. Recommendations include enhancing security headers, publishing security documentation, and maintaining regular third-party script audits to mitigate risks.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and controls.
  2. Add incident response contact information to facilitate reporting and handling of security issues.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Enhance HTTP security headers such as HSTS, X-Content-Type-Options, and Referrer-Policy.
  5. Regularly review and update third-party scripts and plugins to avoid vulnerabilities.

Technical notes

Notes

The website is built on a WordPress CMS platform with a modern tech stack including jQuery, Google Tag Manager, and WP Rocket for performance optimization. It uses multilingual support via WPML and SEO enhancements through Yoast SEO. Hosting is provided by Websupport, inferred from nameservers. The site demonstrates fast loading times, excellent mobile responsiveness, and good accessibility features. Technical debt appears low with current technologies and caching strategies in place. Opportunities exist to further modernize security headers and streamline script loading for enhanced security and performance.
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.
