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

SYLVA is a European Union and SERI funded scientific project focused on real-time observation of aeroallergens, providing valuable environmental data and research outputs. The website serves as a portal for stakeholders including researchers and public health officials, offering access to data portals and project information. The technical infrastructure is modern and lightweight, utilizing htmx and Pico CSS for responsive and accessible design. Embedded iframes provide interactive data visualization and mapping services. Security posture is adequate with HTTPS usage but lacks explicit security headers and privacy policies, which are recommended for improvement. The domain WHOIS data is privacy protected by EURid, typical for .eu domains, and the website content aligns with the domain's purpose, supporting legitimacy. Overall, the site is professional and trustworthy but could enhance compliance and security transparency.

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

10 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  3. 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"

    • 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';…

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 SYLVA project occupies a niche in environmental technology and aerobiology research, supported by EU funding mechanisms. Its business model is grant-based research and data dissemination, targeting scientific and governmental stakeholders. The project leverages partnerships with EU research repositories and networks like AutoPollen. The website's content and social media presence indicate a focus on transparency and stakeholder engagement. Growth potential lies in expanding data services and stakeholder collaboration. The absence of commercial advertising or tracking reflects a research-oriented approach. Strategic partnerships and EU funding provide stability and credibility.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced but lacks visible security headers such as Content-Security-Policy or X-Frame-Options. No forms or user input fields reduce attack surface, but absence of explicit privacy and cookie policies indicates compliance gaps with GDPR and related regulations. No incident response or security contact information is provided, limiting transparency. No vulnerabilities or exposed sensitive data were detected in the HTML content. Recommendations include adding security headers, privacy notices, and incident response contacts to enhance security culture and compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with user consent mechanisms to improve GDPR compliance.
  2. Add standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  3. Publish clear contact information for security incidents and data protection officer details to improve transparency and trust.
  4. Enhance SEO metadata and structured data to improve search engine visibility and accessibility.
  5. Regularly audit and update technical stack and dependencies to mitigate potential vulnerabilities and maintain performance.

Technical notes

Notes

The website uses modern, lightweight technologies including htmx for dynamic content loading and Pico CSS for styling, resulting in good mobile responsiveness and accessibility. The HTML is well-structured with semantic elements and ARIA attributes for navigation clarity. Embedded iframes integrate external data portals and mapping services, enhancing functionality. No CMS or hosting provider details are explicitly detectable. Performance is moderate with no obvious bottlenecks. The absence of analytics or tracking scripts aligns with privacy-conscious design but limits user behavior insights. Technical debt appears low, but adding security headers and metadata would improve robustness.
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.
