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. GDPR outside view

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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

  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

Sirdata operates in the technology and media sectors, providing data-driven marketing and compliance solutions. Their business model revolves around offering SaaS products and consulting services that enable clients to manage user consent and target audiences without relying on third-party cookies. The company leverages partnerships with telecom operators (Utiq technology) and maintains memberships in industry bodies such as ARPP, IAB France, and W3C, enhancing its market credibility. Revenue streams likely include subscription fees for CMP and audience targeting services. The presence of multiple client logos from major media and advertising firms indicates strong market penetration and partnership ecosystem. The company is headquartered in France with an additional office in the UK, founded in 2012, and maintains a medium-sized enterprise profile.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and a robust consent management platform in place, ensuring GDPR compliance. Security best practices include the use of crossorigin attributes on scripts and no visible exposure of sensitive data. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. No vulnerable libraries or insecure forms were detected in the HTML content. The company should consider publishing a security.txt file and providing clear incident response channels to enhance transparency and readiness. Overall, the security posture is solid but could be improved with formalized policies and disclosures.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  3. Deploy explicit Content Security Policy (CSP) headers to mitigate cross-site scripting and related attacks.
  4. Enhance transparency by providing direct contact channels for security incidents such as security@ or abuse@ emails.
  5. Maintain regular security audits and update third-party libraries to prevent vulnerabilities.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for DOM manipulation, AOS for animations, Typed.js for dynamic text effects, and Feather Icons for vector icons. It integrates Google Tag Manager with server-side capabilities and proprietary Sirdata analytics scripts. The site loads asynchronously critical scripts to optimize performance. The presence of multiple external documentation and portal links indicates a well-structured ecosystem. Performance is moderate with good mobile optimization and accessibility features. No CMS was explicitly detected, suggesting a custom or static site architecture. Hosting appears managed under the sirdata.com domain with tag management hosted on tms.sirdata.com. Technical risks are minimal but could be further reduced by implementing advanced security headers and continuous monitoring.
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.
