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

The website aplusa-online.com represents the official online presence for the A+A 2025 trade fair, a world-leading event focused on safety and health at work, organized by Messe Düsseldorf GmbH. The site provides comprehensive information for exhibitors, visitors, and media, including event details, programs, and services. The business is positioned as a major player in the occupational safety and health trade fair sector, targeting professionals and companies in manufacturing and related industries. The website is well-structured, multilingual, and professionally branded, reflecting a mature digital presence. From a technical perspective, the site employs modern JavaScript frameworks and tracking technologies, including Usercentrics for cookie consent, Matomo for analytics, and various advertising and retargeting services. The site is mobile-optimized and accessible, with good SEO practices. However, explicit CMS or hosting provider details are not evident. Performance is moderate, with room for optimization. Security posture is generally good with HTTPS enforced and no exposed sensitive data detected. However, the absence of explicit security headers and lack of published security policies or incident response contacts indicate areas for improvement. Privacy compliance is partially addressed through cookie consent, but no clear privacy policy or terms of service pages were found in the analyzed content. Overall, the site is trustworthy and professional but would benefit from enhanced transparency in privacy and security policies, improved WHOIS data availability, and stronger security header implementation to bolster user trust and compliance.

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. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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 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';…

  3. GDPR outside view

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

    • 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

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

The A+A trade fair is a globally recognized event organized by Messe Düsseldorf GmbH, serving as a platform for companies and professionals in occupational safety and health. The business model revolves around event management, exhibitor services, and visitor engagement. Revenue streams likely include exhibitor fees, ticket sales, sponsorships, and advertising. The target audience includes manufacturers, safety professionals, and government entities. The website's extensive linking to Messe Düsseldorf domains and related service portals indicates a strong partnership ecosystem. Growth indicators include the event's scheduled dates and program expansions. The company maintains a consistent brand and market position as a leader in its niche. Competitive advantages include a comprehensive program, international reach, and integration of digital services such as online registration and exhibitor dashboards. Strategic observations suggest the company leverages digital tools for enhanced user experience but should improve transparency and security disclosures to maintain competitive trust.

Security posture

The website demonstrates a moderate to good security maturity level. HTTPS is enforced, and no sensitive data leaks were observed in the HTML content. The presence of a cookie consent mechanism via Usercentrics indicates awareness of privacy regulations. However, the lack of visible security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security posture. No vulnerability disclosure or security.txt files were found, and no incident response contacts are published, which could hinder timely reporting and mitigation of security incidents. Compliance gaps exist regarding GDPR transparency, as no explicit privacy policy or terms of service pages were detected. The absence of WHOIS data raises concerns about domain registration legitimacy, although the website content aligns with a reputable organization. Overall, the security culture appears moderate but would benefit from enhanced policy publication, security header implementation, and incident response readiness.

Recommendations

  1. Implement and publish comprehensive privacy policy and terms of service pages to improve GDPR compliance and user trust.
  2. Add standard security headers such as CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  3. Publish a security policy and incident response contact information, including a security.txt file, to facilitate vulnerability reporting and response.
  4. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to improve domain legitimacy and trust.
  5. Regularly audit third-party scripts and tracking technologies to minimize privacy risks and optimize performance.

Technical notes

Notes

The website uses a modern JavaScript-based front-end with AngularJS elements and integrates multiple third-party services for analytics, advertising, and consent management. The presence of Usercentrics CMP indicates compliance efforts for cookie consent. The site is mobile responsive and accessible, with structured navigation and SEO-friendly meta tags. Performance is moderate, with potential improvements in loading speed and script optimization. No CMS or hosting provider details are explicitly detected. The technical infrastructure supports a professional event platform but could benefit from enhanced security configurations and clearer technical documentation.
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.
