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

7 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"

      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      • ASVS V3.4.3

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

The company operates a consulting business model enhanced by digital tools, targeting organizations seeking ESG compliance and sustainability transformation. Their key services include double materiality assessments, climate impact evaluations, ESG strategy development, and mentoring. The presence of client logos from diverse sectors indicates a broad partnership ecosystem and market trust. The website's content and structure suggest a focus on delivering impact-driven results efficiently, positioning Sustinere as a competitive player in the Baltic ESG advisory market.

Security posture

The website employs HTTPS with strong SSL configuration and implements key security headers, indicating a solid security foundation. No exposed sensitive data or vulnerable libraries were detected. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. The cookie consent mechanism is present, supporting privacy compliance, but the lack of a detailed privacy policy and terms of service limits full compliance assurance.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to enhance legal compliance and user trust.
  2. Establish and publicize an incident response and vulnerability disclosure policy to improve security transparency.
  3. Add clear contact information including company emails and phone numbers to facilitate communication and trust.
  4. Enhance website accessibility features to improve inclusivity and compliance with accessibility standards.
  5. Regularly review and update third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website is built on WordPress using the Astra theme and Elementor page builder, leveraging modern web technologies such as jQuery and Google Tag Manager. Hosting appears to be managed by Zone Media OÜ, consistent with the domain registrar. Performance is moderate with good mobile optimization and SEO practices. The technical implementation is robust, though accessibility could be improved. The use of structured data (JSON-LD) enhances search engine understanding and visibility. Overall, the technical infrastructure supports the business goals effectively with opportunities for further optimization.
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.
