Diehl Group · Technology · Germany
Low risk. 1 critical or high finding in SSL/TLS.
Diehl Group is a globally active German technology enterprise headquartered in Nürnberg, Germany, with a diversified product range across multiple industrial sectors including metal processing, electronic systems, defence, aviation, and metering technologies. The company employs approximately 18,700 people worldwide and generates annual sales of 4.7 billion euros, positioning it as a significant player in the technology and manufacturing industry. The website reflects a professional corporate presence with clear branding and structured content aimed at industrial customers, partners, suppliers, and job seekers. Technically, the website employs modern web technologies such as HTMX, lazy loading for images, and Matomo analytics for user tracking, combined with a cookie consent mechanism to ensure privacy compliance. The site is mobile optimized, accessible, and SEO-friendly, indicating a mature digital infrastructure. The CMS appears to be Ibexa (formerly eZ Platform), a robust enterprise content management system. From a security perspective, the site enforces HTTPS and implements cookie consent, with no visible security vulnerabilities or exposed sensitive data. However, explicit security headers like X-Frame-Options and X-Content-Type-Options are not clearly detected and could be improved. The absence of a dedicated security policy or incident response information is noted, as is the lack of a security.txt file for vulnerability disclosure. Overall, the website and business appear legitimate and professionally managed, with a strong security posture and good privacy compliance. The missing WHOIS data for the subdomain is typical and does not detract from the trustworthiness of the site. Strategic recommendations include enhancing security header implementation, publishing security policies, and improving contact information visibility for security and compliance inquiries.
Scanned
NIS2 Art. 21(2)
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.
1 finding rated critical or high. Fix these first.
TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.
Server supports weak protocols: TLSv1.1
What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

Each check with its score, findings and the evidence it collected.
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
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.
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.

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.
Automated reading of the public site. Ratings are indicative.
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.
