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

Andersen Construction is a well-established general contractor and construction management firm operating primarily in the Pacific Northwest of the United States, with offices in Portland, Seattle, Boise, and Eugene. Founded in 1950, the company emphasizes collaborative delivery methods such as Design-Build, Integrated Project Delivery (IPD), and Construction Management/General Contracting (CM/GC). Their business model focuses on serving commercial, industrial, healthcare, education, and multifamily housing sectors with a strong reputation for integrity, safety, and client-first service. The website reflects a medium-sized, employee-owned company with a consistent brand and a professional online presence. Technically, the website uses a moderate technology stack including jQuery, Google Analytics, and Elfsight widgets for enhanced user experience and social proof. The site is mobile optimized with good navigation and SEO practices, though accessibility features are basic. Performance is moderate, with room for improvement in security headers and privacy compliance. The absence of explicit privacy and cookie policies and lack of security incident contacts indicate gaps in compliance and security transparency. Security posture is adequate but could be improved by implementing standard security headers and providing clear data protection and incident response information. The WHOIS data is unavailable, which raises concerns about domain legitimacy despite the professional content and strong business signals. Overall, the website is trustworthy and professional but would benefit from enhanced security and compliance disclosures. Strategic recommendations include improving privacy and cookie policies, adding security headers, establishing incident response contacts, and clarifying domain registration details to enhance trust and compliance.

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

8 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

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

Andersen Construction holds a strong market position as a regional leader in construction management and general contracting with a 75-year history. Their competitive advantage lies in their employee-owned culture, focus on collaborative delivery methods, and ability to manage complex projects across multiple sectors. The business model is service-oriented, targeting institutional and commercial clients in the Pacific Northwest. Revenue streams likely derive from project management fees, construction contracts, and specialized services such as preconstruction planning and BIM. The company maintains a robust partnership ecosystem, including trade partners and industry affiliations, supported by active social media engagement. Growth indicators include recent featured projects and awards. Strategic observations suggest a mature company with stable operations but needing to address digital trust and compliance to maintain competitive edge.

Security posture

The current security maturity level is moderate. The website uses HTTPS, which is mandatory for secure communications. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance gaps exist due to missing privacy and cookie policies and lack of GDPR compliance indicators. There is no visible incident response or vulnerability disclosure information, which limits readiness for security incidents. Data protection practices are not explicitly stated, and no Data Protection Officer contact is provided. The security culture appears limited in digital transparency, suggesting room for improvement in security governance and communication.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add standard security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Establish and publish incident response and vulnerability disclosure contacts to improve transparency.
  4. Conduct a security audit of all forms and inputs to ensure protection against injection and CSRF attacks.
  5. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to enhance trust.

Technical notes

Notes

The website infrastructure is built on a traditional web stack using jQuery and third-party widgets for enhanced functionality. Google Analytics and Google Tag Manager are used for user tracking and analytics. The site is mobile responsive with good SEO metadata and Open Graph tags for social sharing. Performance is moderate, with some reliance on external resources that may impact load times. Accessibility is basic, with no explicit ARIA roles or advanced accessibility features detected. The absence of a CMS or hosting provider information limits deeper technical insights. Modernization opportunities include upgrading to newer JavaScript frameworks, improving accessibility, and optimizing performance through resource consolidation and caching strategies.
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.
