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

Algeco GmbH is a well-established German company specializing in the rental and sale of modular container buildings and related services. With over 60 years of experience and a broad European footprint, including 14 locations in Germany and multiple international subsidiaries, Algeco serves diverse sectors such as construction, education, healthcare, and retail. Their business model focuses on providing flexible, sustainable, and efficient space solutions supported by comprehensive 360° services including design, installation, and facility management. The website reflects a professional and mature digital presence with strong branding and clear service offerings. Technically, the website employs modern web technologies including Google Tag Manager, Matomo analytics, and Usercentrics for consent management, ensuring compliance with privacy regulations. The site is mobile-optimized, accessible, and performs moderately well. Security posture is solid with HTTPS enforced and no visible vulnerabilities, though some security headers could be improved. Privacy compliance is robust with clear policies and consent mechanisms. Overall, the security posture is good but could benefit from publishing explicit security policies and incident response contacts.

Strategic recommendations include enhancing security headers, adding vulnerability disclosure information, and maintaining up-to-date third-party scripts to further strengthen security and trust.

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

    • 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 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

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

Algeco GmbH holds a strong market position in the modular building and container rental industry, leveraging decades of experience and a wide European network. Their competitive advantage lies in offering comprehensive 360° services alongside flexible modular solutions, appealing to a broad range of industries requiring temporary or permanent space. The business model is rental and sales-based, supplemented by service packages that enhance customer retention and satisfaction. The company targets businesses, public institutions, and organizations needing rapid deployment of space solutions. Growth indicators include international subsidiaries and active marketing through social media and content channels. Partnerships with regional subsidiaries and use of professional hosting and analytics services indicate a mature operational ecosystem.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of a consent management platform ensuring GDPR compliance. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. Security headers such as Content-Security-Policy and X-Frame-Options are not explicitly present, which could be improved to mitigate risks like clickjacking and cross-site scripting. The use of third-party analytics and marketing scripts is managed with user consent, reducing privacy risks. Overall, the security maturity is good but can be enhanced by formalizing security documentation and improving HTTP header configurations.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy page outlining security practices and compliance.
  3. Provide clear incident response contact information such as security@ or abuse@ email addresses.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Regularly audit and update third-party scripts and dependencies to mitigate vulnerabilities.

Technical notes

Notes

The website is built using modern web technologies including Bootstrap for responsive design, Google Tag Manager and Matomo for analytics, and Usercentrics for consent management. It uses various JavaScript libraries to enhance user experience such as anime.js for animations and glide.js for sliders. The site is mobile-optimized with good accessibility features and SEO meta tags. Performance is moderate, with deferred loading of scripts and optimized images. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not explicit but name servers indicate use of professional hosting providers. Technical risks are minimal but could include dependency on multiple third-party scripts which require ongoing maintenance.
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.
