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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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 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 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';…

  3. 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

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

Rubicon occupies a strong market position as a Microsoft-focused cloud and AI consultancy with a medium-sized business footprint. Their competitive advantage lies in deep Microsoft partnership credentials, a broad service offering, and a focus on secure, data-driven digital transformation. Revenue streams likely include consultancy fees, managed services contracts, and custom AI solution development. The target customer segments are large enterprises, government bodies, and non-profits seeking advanced cloud adoption and AI integration. The company shows growth indicators through partnerships (e.g., IceLake), active content marketing, and a sizable client base. Their ecosystem includes Microsoft and other technology partners, supported by a professional brand and multiple industry awards.

Security posture

Rubicon's security posture is solid with HTTPS enforced, DNSSEC enabled, and use of anti-bot measures like Google reCAPTCHA on forms. CSRF tokens protect form submissions, and cookie consent is implemented to comply with privacy regulations. However, the absence of explicit security policies, incident response contacts, and advanced HTTP security headers (CSP, HSTS, X-Frame-Options) suggests room for improvement. No vulnerabilities or exposed sensitive data were detected in the HTML content. The site does not publish a security.txt file or dedicated vulnerability disclosure program, which could enhance transparency and trust. Overall, the security maturity is good but not at an advanced level.

Recommendations

  1. Implement additional HTTP security headers such as Content-Security-Policy, Strict-Transport-Security, and X-Frame-Options to harden the website against common attacks.
  2. Publish a dedicated security policy page and provide clear incident response contact information to improve transparency and preparedness.
  3. Create and host a security.txt file to facilitate responsible vulnerability disclosure.
  4. Enhance accessibility features to meet higher standards and improve user experience for all visitors.
  5. Regularly audit and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website is built with modern front-end technologies including HTML5, CSS3, Bootstrap framework, and JavaScript libraries such as jQuery and Slick Carousel. It integrates Google reCAPTCHA v3 for bot protection and LinkedIn Insight Tag for marketing analytics. The site is hosted via team.blue nl B.V., a reputable registrar and hosting provider. Performance is moderate with lazy loading of images and videos, though some lazy loading errors were noted. Mobile optimization is good with responsive design and mobile web app capabilities. SEO is well addressed with proper meta tags, Open Graph, and Twitter Card metadata. The site uses CSRF tokens in forms, indicating attention to secure form handling. Overall, the technical infrastructure supports a professional and secure user experience with opportunities for further optimization and security hardening.
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.
