CeramOptec® GmbH · Manufacturing · Germany
Medium risk. 5 critical or high findings in Security headers, SSL/TLS and 1 other check.
CeramOptec® GmbH is a medium-sized German manufacturing company specializing in the production of specialty optical fibers, fiber bundles, cables, and assemblies for industrial, medical, and scientific applications. With over 35 years of experience, the company positions itself as a pioneer offering tailored fiber optic solutions to a diverse industrial clientele. Their product portfolio includes preforms, custom fibers, fiber bundles, and vacuum feedthroughs, supported by a strong presence in trade shows and industry publications. Technically, the website is built on the TYPO3 CMS platform with Bootstrap and jQuery frameworks, providing a responsive and well-structured user experience. The site employs modern analytics tools such as Google Analytics and Google Tag Manager, integrated with a GDPR-compliant cookie consent mechanism. Performance and SEO are moderate to good, with room for improvement in accessibility and security headers. From a security perspective, the site enforces HTTPS and uses cookie consent for privacy compliance. However, no explicit security headers were detected, and incident response contact details are not publicly available. The absence of WHOIS data for the domain reduces trust slightly, though the professional presentation and detailed business information support legitimacy. Overall, CeramOptec's digital presence reflects a mature business with solid technical infrastructure and privacy compliance, but it would benefit from enhanced security practices and transparency in domain registration details.
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.

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.
Forces HTTPS connections
What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"
Prevents clickjacking attacks
What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"
Controls resources the browser is allowed to load
What to do: Implement a Content-Security-Policy appropriate for your application
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
Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.
Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer
What to do: Consider restricting access to FTP or implementing strong authentication

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.

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.
