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

JessenLenz GmbH is an established IT system house based in Lübeck, Germany, offering comprehensive IT services with over 40 years of experience. The company targets businesses seeking reliable IT solutions and positions itself as a trusted provider in the technology sector. The website is built on WordPress using the Divi theme and incorporates SEO best practices via the Yoast SEO plugin. Social media presence on Facebook and Instagram supports brand visibility. Technically, the site is moderately performant and mobile-optimized, though accessibility features are basic. Security posture is adequate with HTTPS enabled and no evident vulnerabilities, but lacks explicit security policies or incident response information. Privacy compliance is limited due to the absence of a privacy policy and terms of service. Overall, the site is professional and trustworthy but would benefit from enhanced privacy and security disclosures.

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

8 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  2. 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.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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';…

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 operates as an essential entity in the technology sector, focusing on IT system solutions and support. Its long-standing market presence suggests stability and experience. The business model revolves around providing end-to-end IT services to organizations, likely generating revenue through service contracts and consulting. The website's content and social media links indicate a moderate digital marketing approach. No partnerships or subsidiaries were identified from the data. Growth potential could be enhanced by improving transparency around privacy and security policies to meet evolving compliance standards.

Security posture

The website demonstrates a basic to moderate security maturity level with HTTPS enabled and no visible sensitive data exposure. However, the absence of security policies, incident response contacts, and vulnerability disclosure mechanisms indicates gaps in security governance and transparency. No security headers were detected in the provided data, which could be improved to enhance protection against common web threats. The cookie consent mechanism is present, supporting GDPR compliance to some extent. Overall, the security posture is functional but could be strengthened by formalizing policies and implementing additional security controls.

Recommendations

  1. Publish a comprehensive privacy policy detailing data collection, processing, and user rights to improve GDPR compliance.
  2. Add a terms of service page to clarify user agreements and legal protections.
  3. Develop and display a security policy including incident response procedures and contact channels for security issues.
  4. Implement a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Enhance website accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website is built on a modern WordPress CMS platform using the Divi theme, which provides flexibility and a professional design. The use of the Yoast SEO plugin indicates attention to search engine optimization. JavaScript and jQuery are utilized for interactive elements. Hosting appears to be managed via InterNetX GmbH, a reputable registrar and hosting provider. Performance is moderate, with room for optimization in loading speed and resource management. Accessibility is basic, suggesting potential technical debt in inclusive design. No critical technical vulnerabilities were identified, but security headers and advanced security configurations are lacking.
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.
