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

AddSecure GmbH is a leading European provider of secure IoT connectivity and end-to-end solutions, focusing on optimizing business operations and securing critical functions across multiple industries including energy, transport, healthcare, and government sectors. The company operates primarily in Europe with a large workforce exceeding 1,000 employees. Their website reflects a mature digital presence with comprehensive content, professional design, and strong branding consistency. Technically, the website is built on WordPress with modern plugins such as Yoast SEO Premium and Complianz GDPR for privacy compliance. It leverages Cloudflare for DNS and CDN services, ensuring good performance and security. The site is mobile-optimized and accessible, with structured data enhancing SEO and user experience. From a security perspective, the site enforces HTTPS, implements key security headers, and follows best practices for secure forms and data handling. However, there is no explicit public vulnerability disclosure or incident response contact information, which could be improved. Privacy compliance is well addressed with a clear privacy policy and cookie consent mechanisms. Overall, the website and business demonstrate a high level of professionalism, trustworthiness, and security maturity. Strategic recommendations include publishing a vulnerability disclosure policy, enhancing incident response transparency, and continuous monitoring of third-party scripts to maintain security posture.

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

4 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 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 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Business profile

AddSecure holds a strong market position as a specialized B2B provider of secure IoT connectivity and related services. Their competitive advantage lies in combining managed services with secure device connectivity tailored for critical infrastructure and transport sectors. Revenue streams likely include subscription-based managed services, product sales, and consulting. The target customers are enterprises requiring high security and compliance, such as utilities, logistics companies, healthcare providers, and municipalities. Growth indicators include a broad European presence and a diversified portfolio of solutions. The company maintains an active partnership ecosystem and invests in certifications like ISO 27001 to reinforce trust and compliance.

Security posture

The security maturity of AddSecure's website is strong, with HTTPS enforced and multiple security headers implemented. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The use of reputable plugins and CDN services further enhances security. However, the absence of a public vulnerability disclosure program and incident response contact details represents a compliance gap. GDPR compliance is well managed through privacy policies and cookie consent. The security culture appears proactive but could benefit from enhanced transparency and formalized incident response communication.

Recommendations

  1. Publish a public vulnerability disclosure or security.txt file to facilitate responsible reporting.
  2. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  3. Regularly audit and update third-party scripts and plugins to mitigate potential vulnerabilities.
  4. Enhance cookie consent transparency with granular user options and detailed policy explanations.
  5. Implement multi-factor authentication for user login portals to strengthen access security.

Technical notes

Notes

The website infrastructure is modern and robust, built on WordPress with a well-curated set of plugins for SEO, privacy, and user engagement. Hosting via Cloudflare provides DNS resilience and CDN acceleration. Performance is moderate with room for optimization. The site is mobile responsive and accessible, adhering to web standards. Technical risks are minimal but include dependency on third-party scripts and plugins which require ongoing maintenance. Opportunities exist to improve performance and security transparency through additional tooling and 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.
