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

Group-Office, operated by Intermesh BV, is a specialized provider of open source groupware and CRM software solutions targeting businesses seeking flexible, privacy-focused collaboration tools. The company offers both self-hosted and cloud-hosted versions, emphasizing data control, GDPR compliance, and integration with native device apps. Their market position is that of a niche player with a strong focus on privacy and customization, supported by transparent business registration and VAT information. Technically, the website employs modern web standards, uses Matomo for privacy-conscious analytics, and supports open synchronization protocols. Security posture is solid with HTTPS and two-factor authentication mentioned, though the absence of explicit security headers and cookie consent mechanisms are areas for improvement. The lack of WHOIS data reduces domain trust somewhat but is mitigated by consistent branding and business transparency. Overall, the website is professional, well-structured, and trustworthy, suitable for its target business audience.

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. 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"

  2. GDPR outside view

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

    • 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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

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

Group-Office operates in the technology sector, providing enterprise-grade groupware and CRM tools with a business model combining open source software downloads and hosted SaaS offerings. Their target customers are small to medium businesses requiring integrated collaboration and customer management solutions. The company demonstrates growth potential through continuous feature updates and custom module development. Their partnership ecosystem includes documentation hosting and analytics services but no explicit third-party business partners were identified. The presence of Chamber of Commerce and VAT registration numbers enhances credibility. The company maintains a consistent brand image and leverages multiple social media platforms for outreach.

Security posture

The security maturity level is moderate to high, with HTTPS enforced and privacy by design principles stated. The use of two-factor authentication and encryption is positive. However, the absence of visible security headers (e.g., CSP, HSTS) and lack of published security policies or incident response contacts indicate room for maturity improvement. No vulnerabilities or exposed sensitive data were detected in the content. GDPR compliance is clearly addressed, but cookie consent mechanisms are missing, which could be a compliance gap. Incident response readiness and vulnerability disclosure processes are not publicly documented, which could impact trust in security incident handling.

Recommendations

  1. Implement and publish a comprehensive cookie policy with a user consent mechanism to enhance GDPR compliance.
  2. Add standard security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to improve security posture.
  3. Publish a dedicated security policy and incident response contact information to increase transparency and trust.
  4. Consider creating and linking a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance website accessibility features to improve inclusivity and compliance with accessibility standards.

Technical notes

Notes

The website uses a modern tech stack with HTML5, CSS3, and JavaScript, including web fonts and asynchronous loading of Matomo analytics scripts. It supports multiple platforms and open synchronization protocols, indicating a well-integrated ecosystem. Performance is moderate with good mobile optimization and SEO practices. No CMS or hosting provider details were detected. The site lacks some advanced accessibility features and security headers, which are technical debt areas. Overall, the infrastructure supports the business needs effectively but could benefit from technical enhancements to security and accessibility.
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.
