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. 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';…
  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 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

Optimizely operates in the technology sector, focusing on AI-driven digital experience solutions for enterprise marketing and digital teams. Their business model is primarily B2B SaaS, offering tools for content creation, personalization, testing, and analytics. The company has a strong market position supported by multiple subsidiary brands, indicating growth through acquisitions. Revenue streams likely include subscription fees and professional services. The target customer segments are medium to large enterprises seeking advanced digital marketing capabilities. The partnership ecosystem includes integrations with major marketing platforms and ad networks. The company's digital presence and technology stack reflect a strategic focus on innovation and customer engagement. Observations suggest a well-established operation with a focus on scalability and AI integration.

Security posture

The security maturity of Optimizely's website is high, with enforced HTTPS, comprehensive security headers, and use of reCAPTCHA to mitigate automated abuse. No exposed sensitive data or vulnerable libraries were detected in the analysis. However, the absence of publicly available security policies, incident response plans, or vulnerability disclosure mechanisms indicates room for improvement in transparency and readiness communication. Compliance with GDPR is indicated by privacy and cookie policies with consent mechanisms. The security culture appears professional but could benefit from enhanced public documentation of security frameworks and certifications. Overall, the risk is low but could be further mitigated by adopting best practices in security communication and incident response.

Recommendations

  1. Publish a formal vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  2. Develop and make publicly available detailed security and incident response policies to enhance transparency.
  3. Regularly audit and update third-party libraries and scripts to prevent vulnerabilities.
  4. Enhance contact information availability, including dedicated security contact channels.
  5. Consider obtaining and displaying recognized security certifications to strengthen trust.

Technical notes

Notes

The website is built on a modern technology stack including React, Azure cloud services, and integrates multiple marketing and analytics tools such as Google Analytics, Microsoft Clarity, Marketo, and Zaius. The CMS platform is EPiServer (now Optimizely CMS), indicating a robust content management system tailored for enterprise needs. Performance is optimized with preloading, preconnecting, and use of CDN resources. The site is mobile-optimized and accessible, with good SEO practices evident in meta tags and structured data. Technical risks are minimal, though the extensive use of third-party scripts requires ongoing monitoring to mitigate supply chain risks. Opportunities exist to further modernize by consolidating tracking scripts and enhancing security transparency.
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.
