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

Prepend is a well-established Atlassian Platinum Solution Partner based in the Netherlands, offering comprehensive services including consultancy, training, licensing, cloud migration, and hosting for Atlassian products such as Jira and Confluence. The company holds multiple certifications and awards, including ISO 27001 and Atlassian Partner of the Year 2020, positioning it as a leading Atlassian specialist in its market. The website reflects a professional and trustworthy business with clear service offerings and strong customer references. Technically, the website employs a modern tech stack with jQuery, Slick Slider, Cookiebot for cookie consent, and Google Tag Manager for analytics. The site is hosted on an IBM Domino CMS platform, optimized for performance and mobile responsiveness, with good SEO and accessibility features. Privacy compliance is well addressed with a clear privacy policy and cookie consent mechanism. Security posture is strong with HTTPS enforced, presence of security headers, and ISO 27001 certification. No critical vulnerabilities or exposed sensitive data were detected. However, the site lacks a public incident response contact or vulnerability disclosure policy, which could be improved to enhance security transparency. Overall, Prepend's website demonstrates a mature digital presence with strong business credibility and security practices, suitable for its role as a trusted Atlassian partner. Strategic recommendations include publishing explicit incident response contacts and vulnerability disclosure information to further strengthen security posture 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.

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

Prepend operates in the technology sector, focusing on Atlassian software solutions for business teams in the Netherlands. Its competitive advantage lies in its Platinum Partner status, comprehensive service portfolio, and recognized certifications. The business model centers on consultancy, training, licensing, and cloud services, targeting medium-sized to large enterprises seeking to optimize collaboration tools. The company showcases a strong partnership ecosystem with Atlassian and related technology providers. Growth indicators include multiple certifications, awards, and a broad client base evidenced by case studies. The website content and structure support a professional and trustworthy brand image, facilitating lead generation and customer engagement.

Security posture

The website exhibits a high level of security maturity, with HTTPS enforced and multiple security headers implemented. The presence of ISO 27001 certification indicates adherence to recognized information security management standards. Privacy compliance is supported by a comprehensive privacy policy and cookie consent mechanism. No exposed sensitive data or vulnerable libraries were found in the HTML content. However, the absence of a public incident response contact or vulnerability disclosure policy represents a gap in security transparency and incident management readiness. Overall, the security posture is strong but could be enhanced by adding explicit channels for security incident reporting and vulnerability disclosures.

Recommendations

  1. Publish a dedicated security incident response contact email or page to facilitate reporting and handling of security issues.
  2. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible disclosure of security vulnerabilities.
  3. Consider adding Data Protection Officer contact information to improve GDPR transparency and compliance.
  4. Regularly review and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance user trust by showcasing security best practices and certifications more prominently on the website.

Technical notes

Notes

The website is built on IBM Domino CMS, integrating modern JavaScript libraries such as jQuery and Slick Slider for UI components. Cookiebot is used for cookie consent management, and Google Tag Manager facilitates analytics and marketing tags. The site demonstrates good performance and mobile optimization, with responsive design and accessibility considerations. SEO is well addressed through meta tags and structured navigation. The technical infrastructure supports a professional and scalable digital presence, though modernization opportunities exist in adopting newer frameworks or CMS platforms to reduce technical debt and improve maintainability.
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.
