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

PROFINET.com is the official website for PROFINET, the leading Industrial Ethernet protocol used globally in industrial automation systems. The site is operated by PROFIBUS Nutzerorganisation e.V., a recognized standards organization based in Germany. The website serves as a comprehensive resource offering protocol information, certification details, training events, and a vibrant community forum to support industrial automation professionals and technology providers. The site is well-branded, professionally designed, and optimized for multiple languages and devices, reflecting a mature digital presence. Technically, the website is built on TYPO3 CMS, leveraging modern JavaScript libraries such as Swiper.js for interactive content and Matomo for privacy-conscious analytics. The site enforces HTTPS and implements a cookie consent mechanism compliant with GDPR, demonstrating a strong commitment to user privacy and security best practices. However, explicit security policies, incident response contacts, and vulnerability disclosure information are not publicly available, representing areas for improvement. Security posture is solid with no visible vulnerabilities or exposed sensitive data. The absence of WHOIS data for the domain is unusual and warrants further verification to confirm domain registration legitimacy. Despite this, the website's content quality, trust signals, and external partnerships strongly support its authenticity and reliability. Overall, PROFINET.com is a high-quality, authoritative resource for industrial Ethernet technology, with recommendations to enhance transparency around security policies and contact information to further strengthen 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

2 findings rated critical or high. Fix these first.

  1. 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

  2. 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.

Dark web exposure

Add-on

Leaked records that mention profinet.com, from OffSeq Breach.

No leaked records found

Breach holds no records for profinet.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

PROFINET.com occupies a leading position in the industrial automation sector as the authoritative source for PROFINET technology. Its business model centers on standardization, certification, education, and community engagement, targeting manufacturers, engineers, and technology providers worldwide. The site promotes training and certification programs, fostering a skilled user base and ecosystem growth. Partnerships with major industry players like Siemens and Molex enhance its market credibility. The multilingual support and active forum indicate a global outreach strategy. The lack of direct contact details suggests a focus on community-driven support rather than direct sales or customer service. The website's integration with PROFIBUS & PROFINET International highlights a strong organizational backing and collaborative industry approach.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent aligned with GDPR, and use of privacy-respecting analytics (Matomo) with DoNotTrack enabled. No security headers were explicitly found in the HTML but are likely implemented server-side given the HTTPS usage. The site does not expose sensitive information or vulnerable libraries. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure program limits transparency and preparedness visibility. The missing WHOIS data for the domain is a concern that should be addressed to confirm domain ownership and reduce risk of impersonation. Overall, the site is secure but could improve by publishing explicit security and incident response information.

Recommendations

  1. Publish a dedicated security policy page detailing security frameworks and practices.
  2. Provide clear incident response contact information including security@ or abuse@ email addresses.
  3. Implement and publicize a vulnerability disclosure policy or security.txt file.
  4. Add a terms of service page to clarify user and legal terms.
  5. Include verified contact information such as company phone numbers and email addresses for general and security inquiries.
  6. Verify and update WHOIS registration data to ensure domain legitimacy and transparency.
  7. Add explicit Content-Security-Policy headers to enhance protection against XSS and related attacks.

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.
