Risk levelMedium

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

Nortek is a specialized technology company focused on oceanographic and subsea navigation solutions, offering advanced Doppler Velocity Log (DVL) and Acoustic Doppler Current Profiler (ADCP) technologies. The company targets marine scientists, oceanographers, and subsea navigation professionals, positioning itself as a key player in the marine technology sector. The website reflects a professional and consistent brand image with good content quality and relevant business descriptions. Technically, the site employs modern frontend technologies such as Tailwind CSS, Vite, and jQuery, hosted behind Cloudflare with HTTPS enabled, indicating a mature digital infrastructure. Security posture is solid with HTTPS and cookie consent management via Cookiebot, though there is room for improvement in security headers and published policies. Overall, the site is trustworthy and well-maintained but lacks explicit privacy and security policy documentation.

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

5 findings rated critical or high. Fix these first.

  1. 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"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  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
  • 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

Nortek operates in the technology sector, specifically in oceanographic instrumentation and subsea navigation. Its business model is B2B, providing specialized hardware and software solutions to scientific and industrial clients. The company has been established since 2011, indicating a stable market presence. The website's integration with social media platforms like Instagram, YouTube, and LinkedIn suggests active engagement with its professional audience. The absence of explicit contact information on the main page may indicate a focus on direct client relationships or controlled lead generation. The use of Cookiebot and Google Tag Manager reflects compliance with modern data privacy and marketing practices, though formal privacy policies are missing. Nortek's market position appears solid within its niche, with a focus on precision navigation and ocean data collection technologies.

Security posture

The website demonstrates a good security baseline with HTTPS enforced and domain status set to clientTransferProhibited, reducing risk of unauthorized domain transfers. Cookie consent is managed through Cookiebot, supporting GDPR compliance. However, the lack of DNSSEC and missing explicit security headers such as Content-Security-Policy and X-Frame-Options are areas for improvement. No security.txt or vulnerability disclosure policies are published, which could hinder incident response transparency. No exposed vulnerabilities or sensitive data leaks were detected in the analyzed content. Overall, the security posture is moderate to good but would benefit from enhanced header policies and published security governance documents.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a comprehensive privacy policy and terms of service to enhance legal compliance and user trust.
  3. Implement and verify security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Create and publish a security policy and incident response contact information, including a security.txt file.
  5. Enhance accessibility features and conduct regular security audits to maintain and improve security posture.

Technical notes

Notes

The website uses a modern frontend stack including Tailwind CSS for styling, Vite for build tooling, and jQuery for legacy support. Hosting is managed via Cloudflare, providing CDN and security benefits. Google Tag Manager and Cookiebot are integrated for analytics and cookie consent management, respectively. Performance is moderate with responsive design and smooth scrolling behavior. SEO is supported by proper meta tags and Open Graph data for social sharing. The site appears to be built on Craft CMS, inferred from freeform form references. There is no evidence of outdated or vulnerable libraries in the provided content. Opportunities exist to improve 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.
