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"

  2. GDPR outside view

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

    • 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

    • 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

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

SIGA operates in the energy-efficient building materials sector, focusing on airtightness and weatherproofing products. Their business model is B2B, serving architects, builders, and installers with specialized products like membranes, tapes, adhesives, and primers. The company maintains a consistent brand presence with multilingual support and regional adaptations, indicating a medium-sized enterprise with international reach. Their digital ecosystem includes social media channels and a blog, enhancing customer engagement and knowledge sharing. The lack of public WHOIS data due to privacy protection is typical for businesses but does not detract from their apparent legitimacy. No direct evidence of parent or subsidiary companies was found. The company emphasizes technical expertise and education through webinars and training, supporting market differentiation.

Security posture

The website demonstrates a solid security posture with HTTPS enabled and no exposed sensitive information in the HTML content. The use of modern frameworks and secure forms indicates attention to security best practices. However, the absence of certain security headers such as Content-Security-Policy and X-Frame-Options suggests room for improvement. No vulnerability disclosure or incident response information is publicly available, which could be enhanced to improve transparency and trust. Cookie consent mechanisms are in place, supporting privacy compliance. Overall, the security maturity is good but could benefit from formalized policies and additional headers.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to enhance browser security.
  2. Publish a clear privacy policy page detailing data handling practices and GDPR compliance to improve privacy transparency.
  3. Establish and publicize a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  4. Add incident response contact information, such as a dedicated security or abuse email address, to improve security communication.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with data protection regulations.

Technical notes

Notes

The website is powered by the Neos CMS built on the Flow PHP framework, indicating a modern and flexible content management infrastructure. It integrates Google Tag Manager and Hotjar for analytics and user behavior tracking, alongside a cookie consent solution from cookie-script.com. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with asynchronous loading of scripts to improve page load times. SEO is well addressed with proper meta tags, Open Graph data, and JSON-LD structured data for organization and breadcrumbs. The hosting provider is not explicitly identified. The technical stack is robust but could be enhanced with additional security headers and performance optimizations.
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.
