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. 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

Anthropic operates in the technology sector with a focus on AI safety and research. Its business model combines research initiatives with product offerings, notably the Claude AI platform. The company maintains a transparent and trust-focused approach, evidenced by dedicated trust centers and responsible scaling policies. The website's external links and partner domains indicate a robust ecosystem around the Claude product line. The absence of direct contact information suggests a controlled communication strategy, typical for specialized tech firms. Growth indicators include active content updates, comprehensive educational resources, and integration with multiple analytics and marketing tools. The company’s market positioning as a public benefit corporation enhances its credibility and appeal to socially conscious stakeholders.

Security posture

The website exhibits a solid security foundation with HTTPS enabled and no exposed sensitive data. The presence of a dedicated security and compliance trust center indicates organizational commitment to security best practices. However, the lack of explicit security headers such as Content Security Policy (CSP) and HTTP Strict Transport Security (HSTS) represents an area for improvement. No vulnerability disclosures or incident response contacts are publicly available, which could hinder rapid response to security events. The use of multiple tracking and analytics scripts necessitates careful privacy management to ensure compliance with regulations like GDPR. Overall, the security maturity is good but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  2. Introduce a cookie consent banner/mechanism to comply with privacy regulations and improve user trust.
  3. Publish a clear and accessible terms of service page to define user rights and obligations.
  4. Establish and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Provide explicit incident response contact information to enhance transparency and readiness.

Technical notes

Notes

The website is built on the Webflow CMS platform, utilizing modern front-end technologies such as Lottie for animations and Google Fonts for typography. It integrates multiple analytics and marketing tools including Google Tag Manager, Facebook Pixel, Amplitude, Reddit plugins, and Segment Analytics, reflecting a sophisticated data collection and user engagement strategy. The site is well-optimized for mobile devices and accessibility, with good SEO practices evident in meta tags and structured navigation. Hosting appears to be managed by Webflow, contributing to fast load times and reliable performance. Technical debt is minimal, though the addition of security headers and privacy compliance features would further enhance the site's robustness.
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.
