Security score

74/100

Risk levelMedium

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

Brunswick Corporation is a global leader in the marine recreation and technology industry, owning over 60 brands including Mercury Marine, Boston Whaler, and Sea Ray. The company operates as an enterprise-level manufacturer and brand owner focused on marine engines, boats, and related technology solutions. The website reflects a professional corporate presence with good content quality and consistent branding. Technically, the site uses modern marketing and analytics tools such as Marketo and Google Tag Manager, is hosted on AWS Cloudfront CDN, and implements HTTPS with good SSL configuration. Privacy compliance is supported by a comprehensive privacy policy and a OneTrust cookie consent mechanism. However, the absence of WHOIS data for the domain introduces some uncertainty about domain registration transparency. Security posture is strong with HTTPS and cookie consent but could be improved by adding security headers and explicit incident response contacts. Overall, the site is trustworthy and well-maintained, suitable for its business audience.

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

3 findings rated critical or high. Fix these first.

  1. 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

  2. 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 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';…

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

Brunswick Corporation holds a strong market position in the marine recreation sector with a diversified portfolio of well-known brands. Its business model centers on manufacturing and technology innovation in marine products. The website targets industry stakeholders, customers, and investors, providing corporate information and brand visibility. The use of advanced marketing tools indicates a mature digital marketing strategy. The lack of visible contact information and WHOIS transparency may limit direct customer engagement and trust signals but does not detract significantly from its enterprise stature. The company likely generates revenue through product sales, brand licensing, and technology services. No direct partnerships or subsidiary domains were identified beyond known brand mentions.

Security posture

The website demonstrates a solid security foundation with enforced HTTPS and a cookie consent mechanism compliant with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options is a gap that could be exploited. There is no published security policy or incident response contact information, which are important for transparency and readiness. The WHOIS data unavailability raises moderate concerns about domain registration legitimacy but is not uncommon for large enterprises using privacy services. Overall, the security posture is good but can be enhanced with additional headers and published policies.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file and incident response contact information to improve transparency and vulnerability reporting.
  3. Add a clearly accessible terms of service page to clarify legal terms for users.
  4. Enhance accessibility features to meet WCAG standards for broader compliance.
  5. Improve WHOIS transparency or provide domain registration details on the website to build trust.

Technical notes

Notes

The website uses a modern technology stack with Google Tag Manager, Marketo Munchkin for marketing automation, OneTrust for cookie consent, and FontAwesome for icons. It is hosted on AWS Cloudfront CDN, which supports good performance and scalability. The site is mobile optimized with responsive design and includes SEO-friendly meta tags and Open Graph data. Accessibility is basic but could be improved. No CMS was explicitly detected. The site loads a variety of external scripts from trusted domains. Performance is moderate, likely due to multiple third-party scripts. Technical debt appears low, but security header implementation is incomplete. Overall, the technical infrastructure supports a professional corporate website with room for security and accessibility enhancements.
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.
