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

AE Rental Veranstaltungstechnik is a well-established full-service provider of professional event technology based in Münster, Germany. Founded in 2010, the company offers a comprehensive range of rental services including sound, lighting, stage, video, and media technology, as well as mobile power solutions and event planning. Their market position is strong regionally, supported by a consistent brand presence, excellent customer reviews, and a broad portfolio of services tailored for festivals, corporate events, private celebrations, and hybrid digital events. Technically, the website is built on the Contao CMS platform, utilizing modern JavaScript libraries such as jQuery and Colorbox for enhanced user experience. The site is well-optimized for mobile devices, fast loading, and SEO-friendly, with extensive structured data markup to improve search engine visibility. Privacy compliance is robust, featuring a comprehensive privacy policy, cookie consent mechanisms, and GDPR adherence. From a security perspective, the site enforces HTTPS and employs best practices such as consent-based analytics activation and anti-spam measures in forms.

Overall, AE Rental's digital presence reflects a professional, trustworthy, and customer-focused business with strong technical and privacy standards. Strategic enhancements in security policy transparency and header implementation could further strengthen their security posture.

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

5 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

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  2. 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 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';…

  3. 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

  4. 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

  • 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

AE Rental operates in the event technology rental and event planning sector, targeting event organizers, corporate clients, and private individuals primarily in Münster and the surrounding Münsterland region. Their business model centers on equipment rental combined with full-service event support, including technical planning and on-site assistance. The company leverages a diverse service portfolio, including specialized offerings like Funktion-One sound systems and hybrid event technology, positioning them competitively in a niche market. Their strong online presence, customer ratings, and comprehensive service catalog indicate a mature business with growth potential. Partnerships with venues and active social media engagement support their market reach and brand recognition.

Security posture

The website demonstrates a mature security posture with mandatory HTTPS encryption and privacy-conscious analytics deployment. The presence of a honeypot field in the contact form indicates proactive spam mitigation. However, the absence of explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options suggests room for enhancement to protect against common web vulnerabilities. No incident response or security contact information is published, which could be a gap in transparency and readiness. Overall, the site maintains a secure environment suitable for its business operations but would benefit from formalizing and publishing security policies and improving header configurations.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact channels to improve transparency and trust.
  3. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  4. Enhance monitoring and logging mechanisms to detect and respond to security incidents promptly.
  5. Continue maintaining GDPR compliance and update privacy and cookie policies as regulations evolve.

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.
