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

Attendu is a technology company offering a SaaS platform for seamless event management, including invitations, ticket sales, event websites, and guest management. The platform targets event organizers and attendees globally, serving hundreds of thousands of guests annually. The website is professionally designed using the Framer CMS platform and incorporates modern tracking technologies such as Google Tag Manager and Leady.com. However, the absence of WHOIS registration data raises concerns about domain legitimacy. The site lacks visible privacy, cookie, and terms of service policies, as well as contact information, which impacts trust and compliance. Security headers and SSL configuration details are not evident, suggesting room for improvement in security posture. Overall, the website is functional and well-designed but requires enhancements in transparency, security, and compliance to improve trustworthiness and reduce risk.

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

6 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 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';…

  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

Attendu operates in the event management technology sector, providing a platform that streamlines event organization processes. Its business model is SaaS-based, targeting medium-sized enterprises and event organizers worldwide. The company appears to have a moderate market presence with a focus on user-friendly event solutions. The lack of detailed business registration and contact information limits the ability to fully assess its competitive positioning and growth potential. The use of advanced marketing tools indicates an active approach to customer acquisition. Strategic partnerships or subsidiaries are not evident from the available data.

Security posture

The website demonstrates a basic security posture with HTTPS enabled and use of Google Tag Manager for analytics. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, and no explicit incident response or security contact information is provided. The absence of privacy and cookie policies indicates potential compliance gaps with GDPR and other data protection regulations. The lack of WHOIS data further complicates trust assessment. There are no visible vulnerabilities or exposed sensitive data, but the overall security maturity is low to moderate. Enhancements in security headers, transparency, and incident response readiness are recommended.

Recommendations

  1. Register the domain properly and ensure WHOIS data is publicly available or justified if privacy protected.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements and consent mechanisms.
  3. Implement standard security headers to protect against common web vulnerabilities.
  4. Provide clear and accessible contact information including security and incident response contacts.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website is built using the Framer CMS platform, leveraging modern web technologies and tracking tools such as Google Tag Manager and Leady.com. The site is mobile optimized and has good SEO metadata including Open Graph and Twitter cards. Performance is moderate with asynchronous loading of scripts. However, no hosting provider or server infrastructure details are evident. The absence of security headers and detailed SSL configuration information suggests technical debt in security implementation. There is an opportunity to improve accessibility features and enhance compliance-related technical controls.
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.
