Risk levelHigh

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

ARNO Werkzeuge is a German manufacturing company specializing in precision cutting tools for turning, long turning, grooving, drilling, and milling applications. The company offers a broad portfolio of tooling systems and tool management solutions, targeting manufacturing professionals and industries requiring high-quality tooling. Their website is professionally designed using TYPO3 CMS, hosted on AWS infrastructure, and supports multiple languages, indicating a global market presence. The technical infrastructure includes modern analytics and consent management tools, reflecting a mature digital presence. Security posture is adequate with HTTPS and cookie consent implemented; however, there is room for improvement in security headers and published security policies. Overall, the website is trustworthy and well-positioned in its industry, though it lacks explicit privacy and terms of service documentation. Strategic improvements in compliance and security transparency would enhance trust and regulatory adherence.

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

8 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

  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

  3. Network security

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

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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

  4. 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"

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.

Technical appendix

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

Business context

Business profile

ARNO Werkzeuge holds a strong position in the manufacturing sector, focusing on high-precision tooling solutions. Their business model revolves around manufacturing and distributing cutting tools and tool management systems, supported by customer service and an online shop. The company targets industrial clients requiring specialized tooling, leveraging innovation and quality as competitive advantages. The partnership with cellarno.shop suggests an integrated e-commerce channel. The website content and structure support a medium-sized enterprise with consistent branding and detailed product information, indicating a stable and growth-oriented operation.

Security posture

The website enforces HTTPS and uses a reputable consent management platform (Usercentrics), which supports GDPR compliance efforts. However, the absence of explicit security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security robustness. No incident response or vulnerability disclosure information is published, which could hinder rapid response to security events. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. The security posture is moderate but would benefit from enhanced header implementation and published security policies to improve resilience and customer trust.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish clear privacy policy and terms of service pages accessible from the website footer or main navigation.
  3. Add a security policy and incident response contact information to improve transparency and readiness.
  4. Introduce a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility features to meet compliance standards and improve user experience.

Technical notes

Notes

The website is built on TYPO3 CMS, a mature and flexible content management system, hosted on Amazon AWS infrastructure, ensuring scalability and reliability. Integration of Google Tag Manager and Hotjar indicates active user behavior tracking and analytics. The site uses Usercentrics CMP for cookie consent, supporting privacy compliance. Performance is moderate with good mobile optimization and SEO practices. However, accessibility features appear basic and could be improved. The technical stack is modern and well-maintained but could benefit from enhanced security configurations and documentation.
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.
