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

corosys technologies GmbH is a German-based industrial company specializing in the development and delivery of complete process systems and engineering plants for the beverage, chemical, pharmaceutical, and food industries. The company operates through multiple subsidiaries, each focusing on specific sectors such as beverage technology, chemical and pharma technology, food technology, and filtration consulting. Their market position is that of a specialized B2B engineering and manufacturing provider with a strong focus on process technology solutions. The website reflects a professional and consistent brand image targeting industrial clients in Germany and possibly broader European markets. Technically, the website employs modern frontend technologies including Bootstrap, jQuery, and FontAwesome, with analytics powered by Matomo and security features such as Cloudflare Turnstile captcha for form protection. The site is mobile-optimized and includes GDPR-compliant cookie consent mechanisms, indicating a mature digital presence. Security posture is adequate with best practices observed in form protection and privacy compliance, though there is room for improvement in publishing explicit security policies and enhancing HTTP security headers. The WHOIS data is notably missing or inaccessible, which raises questions about domain registration legitimacy; however, the website content and contact information appear legitimate and professional. Overall, the site scores well on content quality, technical implementation, and privacy compliance, with a moderate security posture and good business credibility.

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

9 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

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

corosys technologies GmbH operates in the manufacturing sector with a focus on process engineering for beverage, chemical, pharmaceutical, and food industries. Their business model is B2B, providing engineering solutions and complete process systems. The company leverages a network of subsidiaries to cover specialized industry segments, enhancing their competitive advantage through focused expertise. The website indicates a medium-sized enterprise with a strong German market presence. The company maintains partnerships, such as with M&L Consulting, and promotes job opportunities, suggesting growth and investment in human capital. Revenue streams likely derive from engineering projects, system deliveries, and consulting services. The website's professional design and comprehensive contact information support credibility and customer engagement. Strategic observations include the need to clarify domain registration status and enhance security transparency to strengthen trust further.

Security posture

The website demonstrates a moderate security maturity level. Key strengths include the use of HTTPS (inferred), Cloudflare Turnstile captcha protecting the contact form, and a GDPR-compliant cookie consent mechanism with granular user controls. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security policies, incident response contacts, or vulnerability disclosure mechanisms indicates gaps in security governance and transparency. The lack of HTTP security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces the overall security posture. The missing WHOIS data for the domain is a concern and should be investigated to ensure domain legitimacy. Compliance with GDPR is evident, but additional documentation on data protection officer contact and incident response would improve readiness. Overall, the security posture is adequate for a medium-sized industrial business but requires enhancements to meet higher standards and regulatory expectations.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response contact information on the website.
  2. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Configure and enforce HTTP security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Verify and update domain WHOIS registration details to ensure transparency and trustworthiness.
  5. Conduct regular security audits of third-party scripts and dependencies to mitigate potential vulnerabilities.

Technical notes

Notes

The website is built using a modern technology stack including Bootstrap 5.3.2 for responsive design, jQuery 3.7.1 for DOM manipulation, and FontAwesome 6.7.2 for iconography. Analytics are handled by Matomo, a privacy-focused analytics platform, with cookie-less tracking enabled. The contact form integrates Cloudflare Turnstile captcha for bot protection, indicating attention to form security. Hosting appears to be behind Cloudflare services, providing CDN and security benefits. Performance is moderate with no major issues detected, and mobile optimization is good. SEO is supported by proper meta tags and canonical links. Accessibility features are basic but present. There is no detected CMS, suggesting a custom or static site architecture. Opportunities exist to improve technical SEO, accessibility, and security header implementation to reduce technical debt and enhance user experience.
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.
