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

Extellio is a technology company offering a comprehensive web analytics platform designed for web teams, marketers, and UX professionals. Their platform integrates analytics, surveys, heatmaps, session recordings, and support services, with a strong emphasis on GDPR compliance and ease of use. The website is built on HubSpot CMS and leverages Matomo for analytics tracking, alongside CookieYes for cookie consent management. The site is professionally designed with good navigation and mobile optimization, providing a positive user experience. However, the absence of publicly accessible privacy policy and terms of service pages, as well as missing WHOIS registration data, introduces some concerns regarding transparency and trustworthiness. Security posture is moderate, with cookie consent implemented but lacking security headers and vulnerability disclosures. Overall, the site is functional and professional but would benefit from enhanced transparency and security practices.

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

1 finding rated critical or high. Fix these first.

  1. 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

Extellio positions itself as a GDPR-safe alternative in the web analytics market, targeting website managers, web analysts, UX professionals, and agencies. Their SaaS business model includes subscription-based access to an all-in-one analytics platform and additional support services. The company leverages HubSpot's marketing and CMS ecosystem, indicating a modern digital marketing approach. The lack of WHOIS data and direct contact information limits full verification of business legitimacy. The platform's focus on actionable insights and compliance suggests a niche targeting privacy-conscious customers. Growth potential is indicated by the availability of demos and free trials, but further transparency would strengthen market confidence.

Security posture

The website demonstrates a moderate security maturity level. HTTPS is implied but SSL configuration details are unavailable. Cookie consent is actively managed via CookieYes, supporting GDPR compliance. However, no security headers such as Content Security Policy, HSTS, or X-Frame-Options were detected, which are recommended best practices. There is no visible vulnerability disclosure or security.txt file, and no direct security contact information is provided. The absence of WHOIS data raises questions about domain registration transparency. Overall, while basic privacy compliance is addressed, the security posture could be improved by implementing additional headers, publishing security policies, and enhancing incident response readiness.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service accessible from the website footer or main navigation.
  2. Implement and configure security headers including Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), X-Frame-Options, and X-Content-Type-Options.
  3. Provide clear contact information including security and incident response contacts such as security@ or abuse@ email addresses.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  5. Verify and publish domain registration details to improve trust and legitimacy perception.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing modern web technologies including SVG animations, JavaScript, and CSS3. It integrates Matomo analytics for user tracking and CookieYes for cookie consent management. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, with no major errors or broken elements detected. However, the absence of security headers and limited accessibility features indicate areas for technical improvement. The WHOIS data is missing, which is unusual for an active commercial site and suggests a need for domain registration verification. Overall, the technical infrastructure supports a professional SaaS offering but requires enhancements in security and 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.
