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. 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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';…

  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.

    • 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

SysEleven operates in the technology sector as an essential entity providing managed cloud services with a focus on Kubernetes and sovereign cloud solutions. Their business model revolves around offering managed cloud infrastructure and related services to enterprises, emphasizing performance, stability, and security. The company maintains a professional online presence with clear contact information and active social media channels on LinkedIn, YouTube, and GitHub, indicating engagement with the tech community. The absence of detailed WHOIS registrant data limits full verification, but the domain and hosting appear consistent with the business claims. The company likely generates revenue through subscription or usage-based cloud services and partners with other technology providers. Growth indicators include a comprehensive product portfolio and educational resources such as workshops. Strategic partnerships and certifications were not explicitly found but may exist outside the provided data.

Security posture

The website enforces HTTPS with excellent SSL configuration, indicating a secure transport layer. Cookie consent is managed via the Borlabs Cookie plugin, supporting GDPR compliance. However, no explicit security headers such as Content-Security-Policy or X-Frame-Options were detected, which could enhance protection against common web attacks. There is no visible security policy or incident response contact information, nor a vulnerability disclosure or security.txt file, which are best practices for transparency and security readiness. No vulnerabilities or exposed sensitive data were found in the provided content. The security score is good but could be improved by implementing additional headers, publishing security policies, and formalizing incident response channels. Overall, the security posture is mature but with room for enhancement in transparency and defense-in-depth measures.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response contact information on the website.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve web security.
  3. Create and maintain a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Ensure all web forms include anti-CSRF tokens and input validation to prevent injection attacks.
  5. Enhance accessibility features and provide a clear privacy policy and terms of service to improve compliance and user trust.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using Elementor as the page builder, Bootstrap 4 for responsive design, and Font Awesome for icons. It uses jQuery 3.7.1 and includes Borlabs Cookie for cookie management and consent. The site loads external resources from trusted domains such as cdn.elementor.com and social media platforms. Performance is moderate with good mobile optimization and basic accessibility features. SEO is supported by Rank Math PRO plugin with proper meta tags and structured data (JSON-LD) describing the organization, website, and articles. The hosting provider is not explicitly identified, but the domain uses a custom nameserver dns5.syseleven.net. The technical stack is mature and well-integrated, though improvements in security headers and accessibility could further enhance the site.
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.
