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
    • 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

  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 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

Jacobs operates in multiple critical sectors such as energy, transportation, and government infrastructure, targeting large enterprise and public sector clients. Its business model focuses on B2B professional services, offering program management, engineering, digital advisory, and sustainability solutions. The company maintains a strong market position as a global leader with a broad portfolio of services and industry expertise. The website's structure and content indicate a strategic emphasis on digital transformation and AI-enabled solutions, reflecting growth in technology-driven consulting. Partnerships and related domains like careers and investor relations subdomains support a comprehensive corporate ecosystem. The absence of direct contact emails or phone numbers suggests a controlled communication channel via forms, typical for large enterprises.

Security posture

The website employs HTTPS with strong SSL configuration and implements key security headers such as Content-Security-Policy and Strict-Transport-Security, enhancing protection against common web threats. Cookie consent is managed through OneTrust, indicating GDPR compliance efforts. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the lack of publicly available incident response contacts or vulnerability disclosure policies represents a gap in transparency and readiness communication. The security score is high but could be improved by publishing explicit security policies and contact channels. Overall, the site reflects a mature security posture suitable for an enterprise-level organization.

Recommendations

  1. Publish a dedicated incident response page with clear contact information to improve transparency and readiness.
  2. Implement and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  3. Explicitly list security certifications and compliance frameworks to strengthen trust and credibility.
  4. Enhance contact information availability by including verified company emails and phone numbers for customer support.
  5. Regularly review WHOIS data and domain registration details to ensure consistency and mitigate privacy-related trust concerns.

Technical notes

Notes

The website is built on Drupal 11, a modern and widely supported CMS, ensuring scalability and security. It uses lazy loading for images (LazySizes), Google Tag Manager and Analytics for tracking, and OneTrust for cookie consent management. Performance monitoring is enabled via Boomerang scripts. Hosting appears to leverage Akamai CDN for global content delivery and performance optimization. The site is mobile-optimized with responsive design and accessibility features. SEO best practices are followed with proper meta tags and structured navigation. No critical technical debt or vulnerabilities were identified in the provided HTML content. Opportunities exist to enhance technical transparency around security and incident response.
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.
