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 holds a strong market position as a leader in content marketing platforms, supported by Gartner recognition and a robust customer base including enterprise clients. Its SaaS business model focuses on delivering AI-driven marketing solutions that reduce time-to-market and improve content ROI. The company targets marketing professionals and large organizations, leveraging partnerships with platforms like Marketo and integrations with CMS and social channels. Growth indicators include continuous AI innovation and a comprehensive product suite. The partnership ecosystem is solid, with integrations enhancing platform value. Operationally, the company emphasizes transparency, alignment, and efficiency in marketing workflows.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, use of reputable monitoring and analytics services, and no visible security flaws or data leaks. However, explicit security policies and incident response contacts are not published, which could be improved. The site lacks a public vulnerability disclosure program and detailed security framework references. Privacy compliance is strong with GDPR-aligned policies and cookie consent mechanisms. Overall, the security maturity is good but could benefit from enhanced transparency and formalized security documentation.

Recommendations

  1. Publish a dedicated security policy page outlining security frameworks and controls.
  2. Implement and publicize a vulnerability disclosure and bug bounty program.
  3. Ensure all recommended security headers (CSP, X-Frame-Options, X-Content-Type-Options) are explicitly set and documented.
  4. Enhance incident response readiness by providing clear security contact channels.
  5. Maintain and regularly update privacy and cookie policies to reflect evolving regulations.

Technical notes

Notes

The website is built on a modern React framework with extensive use of JavaScript modules and asynchronous loading for performance optimization. Integration with marketing automation (Marketo), analytics (Google Analytics, Microsoft Application Insights), and customer engagement tools (Zaius) indicates a sophisticated digital marketing infrastructure. Hosting appears to be on Microsoft Azure, leveraging its monitoring capabilities. The site is mobile-optimized, accessible, and SEO-friendly with proper meta tags and structured data. Technical risks are minimal, with no deprecated or vulnerable libraries detected. Opportunities exist to improve security header implementation and formalize security documentation.
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.
