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

Norddeutsche Seekabelwerke GmbH (NSW) is a leading German manufacturer specializing in communication, marine, energy, and offshore cables, as well as technical plastic and environmental products. With a legacy spanning over 125 years, NSW is part of the global Prysmian Group, a world leader in energy and telecommunications cable systems. The company targets industrial and business customers, offering a broad portfolio of cable technologies and customized plastic solutions. The website reflects a professional corporate presence with clear branding and comprehensive product and career information. Technically, the website is built on WordPress 7.0.1 using the Yootheme theme and UIkit framework, ensuring a modern and responsive user experience. The site includes multimedia content such as videos and image galleries, optimized for desktop and mobile devices. While performance is moderate, the site is well-structured with good SEO and accessibility features. From a security perspective, the site uses HTTPS with a good SSL configuration but lacks explicit security headers and a cookie consent mechanism, which are recommended for enhanced protection and GDPR compliance. No vulnerability disclosure or incident response information is provided, indicating room for improvement in security transparency. Overall, the website is trustworthy and professional, though the absence of WHOIS data for the domain www.nsw.com raises questions about domain registration legitimacy. However, the strong corporate branding and association with Prysmian Group mitigate this concern. Strategic recommendations include implementing security headers, cookie consent, and publishing security policies to strengthen compliance and trust.

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

11 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: SMB

      Port 445 (SMB) is publicly accessible - SMB - Windows file sharing, high risk

      What to do: Immediately restrict access to SMB using firewall or VPN

      • 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
    • 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

      • 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
    • 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

  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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

NSW holds a strong market position as a specialized manufacturer in the energy and telecommunications sectors, leveraging over a century of experience and integration within the Prysmian Group. Its business model focuses on manufacturing and distributing high-quality cables and plastic products tailored to industrial needs. The company targets business clients and potential employees, emphasizing career opportunities and certifications. The website's linkage to Prysmian.com and a dedicated shop domain (nswproducts.com) indicates a structured partnership and sales ecosystem. Growth indicators include active recruitment and recent news updates. The company maintains a professional digital presence but could enhance marketing and analytics capabilities.

Security posture

The website demonstrates a moderate to good security posture with mandatory HTTPS enabled and no visible exposure of sensitive data. However, the lack of security headers such as Content Security Policy (CSP), X-Frame-Options, and HSTS reduces defense-in-depth. The absence of a cookie consent banner and explicit privacy compliance mechanisms suggests partial GDPR adherence. No incident response or vulnerability disclosure information is available, limiting transparency. The use of popular CMS and plugins requires regular updates to mitigate vulnerabilities. Overall, the security maturity is adequate but can be improved by adopting best practices and enhancing user privacy controls.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Deploy a cookie consent mechanism to comply fully with GDPR and improve user privacy transparency.
  3. Publish explicit security policies and incident response procedures on the website to increase trust and preparedness.
  4. Add a security.txt file or vulnerability disclosure program to encourage responsible reporting of security issues.
  5. Regularly audit and update all CMS components and plugins to minimize risks from known vulnerabilities.

Technical notes

Notes

The website is built on a modern WordPress platform with the Yootheme theme and UIkit framework, providing a responsive and visually appealing design. Multimedia elements such as videos and image galleries are integrated effectively. The site uses Contact Form 7 for user inquiries, indicating standard form handling. Performance is moderate, with no major errors or broken elements detected. SEO and accessibility features are well implemented, including meta tags and ARIA roles. However, the hosting provider is not identified, and no advanced analytics or marketing tools are detected. Technical debt appears low, but security enhancements and cookie management are recommended.
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.
