Security score

41/100

Risk levelHigh

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

REO AG is a well-established German family-run company with a 100-year history specializing in the development and production of inductive, resistive, and electronic components for various industrial sectors including energy, transportation, and manufacturing. The company operates internationally with subsidiaries across Europe, North America, Asia, and the Middle East, maintaining production primarily in Germany with a focus on quality and innovation. Technically, the website is built on a modern WordPress CMS with Elementor and Yoast SEO, indicating a good level of digital maturity. However, the absence of a valid SSL certificate and HTTPS support is a critical security weakness that undermines user trust and data protection. The site lacks advanced security headers and cookie consent mechanisms, which are important for GDPR compliance and overall security posture. Business credibility is strong with clear contact information, social media presence, and detailed product and industry information. Strategic improvements in security and privacy compliance are recommended to enhance trust and protect user data.

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

7 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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 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"

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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 · found on this site
  • 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

REO AG holds a strong market position as a medium-sized manufacturer of specialized electronic components with a diversified product portfolio including transformers, chokes, power controllers, and resistors. Their business model focuses on B2B sales with customized solutions tailored to industrial clients in sectors such as vibratory conveyor technology, e-mobility, railway technology, and medical technology. The company leverages its century-long expertise and family business values to maintain customer trust and innovation leadership. Their international subsidiaries support global market reach. The website content and structure reflect a professional and customer-focused approach, supporting lead generation and customer engagement through product finders and contact forms. Partnerships and regional domains indicate a broad ecosystem supporting localized markets.

Security posture

The current security posture of the website is weak due to the lack of HTTPS and a valid SSL certificate, exposing visitors to potential data interception risks. The absence of security headers such as Content-Security-Policy and HSTS further increases vulnerability to common web attacks. While no critical vulnerabilities like Heartbleed or POODLE are detected, the missing encryption and security best practices represent significant compliance and risk gaps, especially under GDPR and NIS2 regulations. No explicit incident response or security policy information is available, which may indicate limited transparency or preparedness in security incident handling. The site uses secure and reputable plugins but should urgently address transport layer security and privacy compliance to protect user data and maintain trust.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire website.
  2. Implement HTTP security headers including HSTS, Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.
  3. Add a cookie consent banner and explicit cookie policy to comply with GDPR requirements.
  4. Publish a clear security policy and incident response contact information to improve transparency and readiness.
  5. Regularly audit and update plugins and dependencies to avoid vulnerabilities and maintain performance.

Technical notes

Notes

The website is built on WordPress 6.8.1 with Elementor 3.29.1 and Yoast SEO Premium, indicating a modern and SEO-optimized platform. The use of Contact Form 7 and Royal Elementor Addons enhances functionality. Hosting appears to be with kundenserver.de, a known German hosting provider. Performance metrics are not provided but inferred as slow due to zero load time/resource count data. Mobile optimization is good with responsive design and accessibility features are basic but present. The site uses Brevo for email marketing but lacks advanced analytics or tracking services. Technical debt is moderate with opportunities to improve security and performance. The site structure and metadata are well-formed, supporting SEO and social sharing.
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.
