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

Northern Offshore Services is a specialized maritime service provider focusing on crew transfer and multipurpose vessels primarily serving the offshore wind industry. The company operates a diverse fleet of vessels designed for efficient offshore operations, cargo transport, and personnel transfer. Their market position is that of an established medium-sized player with a strong presence in Northern Europe, supported by multiple office locations in Sweden, Denmark, and the UK. The website reflects a professional digital presence built on WordPress with modern SEO and structured data implementations. However, some technical debt is noted with outdated JavaScript libraries and redundant analytics scripts. Security posture is generally good with HTTPS and nonce usage, but lacks advanced security headers and explicit incident response documentation. Privacy compliance is basic with privacy and cookie policies present but missing active consent mechanisms. Overall, the website is trustworthy and professionally maintained, supporting the company's 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

6 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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';…

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

The company targets offshore wind industry operators and maritime service companies, offering vessel charter and offshore support services. Their business model revolves around providing specialized vessels and technical management services. The presence of multiple vessel classes and detailed fleet information indicates a broad service offering tailored to diverse offshore needs. The parent company, Northern Offshore Group, is linked, suggesting a larger corporate structure. The company demonstrates growth potential and a commitment to sustainability and safety, as indicated by dedicated website sections. The partnership ecosystem includes the parent group and industry-related entities. Strategic observations highlight the company's focus on flexibility, efficiency, and customer-tailored solutions in a competitive offshore market.

Security posture

The website exhibits a moderate security maturity level with HTTPS enforced and nonce tokens protecting AJAX calls. However, the use of an outdated jQuery version introduces potential vulnerabilities. The absence of security headers such as Content Security Policy and X-Frame-Options reduces defense-in-depth. No explicit security or incident response policies are published, which may impact compliance and readiness. Privacy policies are present and GDPR compliance is indicated, but cookie consent mechanisms are lacking. No visible vulnerabilities such as exposed credentials or injection points were detected. The security culture appears basic but functional, with room for improvement in transparency and technical controls.

Recommendations

  1. Update all JavaScript libraries, especially jQuery, to the latest secure versions to mitigate known vulnerabilities.
  2. Consolidate Google Analytics scripts to a single instance to improve performance and reduce tracking redundancy.
  3. Implement a cookie consent banner or mechanism to comply fully with GDPR and enhance user privacy transparency.
  4. Publish explicit security and incident response policy pages to improve compliance and stakeholder trust.
  5. Add security headers such as Content Security Policy, X-Content-Type-Options, and X-Frame-Options to strengthen site security.

Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO plugin and uses jQuery 1.12.4 along with Slick Slider and WPC Tools plugins. The site loads multiple Google Analytics scripts and LinkedIn Insight Tag for tracking. Performance is moderate with good mobile optimization and basic accessibility features. Structured data is implemented via JSON-LD for SEO benefits. Some technical debt is present due to outdated libraries and redundant scripts. Hosting provider is not explicitly identified. The site uses HTTPS with good SSL configuration but lacks advanced security headers. Overall, the technical infrastructure supports a professional web presence but would benefit from modernization and security hardening.
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.
