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

Project Leonardo operates as an internet service provider specializing in hosting online libraries that distribute free content in arts and sciences. The website serves as a portal linking affiliated libraries such as IMSLP-EU and PML-CA, focusing on copyright-compliant content distribution. The business model centers on providing optimized hosting resources tailored to legal and performance requirements. The market position is niche, catering to a specialized audience of online library users and contributors. Technically, the website is simple and static, built with basic HTML and CSS without modern frameworks or CMS detected. There is no evidence of advanced analytics, tracking, or dynamic content. The site lacks mobile optimization and accessibility features, indicating a low level of digital maturity. Hosting details are not explicit, but server locations are optimized for copyright compliance. From a security perspective, the domain is well-registered with a reputable registrar and has a long history, which supports legitimacy. However, the site lacks DNSSEC, security headers, and visible HTTPS enforcement, which are notable gaps. No incident response or security policies are published, and no cookie consent mechanism is present. These factors reduce the overall security posture and privacy compliance. Overall, the website is functional and trustworthy for its niche purpose but would benefit from modern security and privacy enhancements. Strategic improvements in HTTPS enforcement, security headers, and privacy policies would strengthen its risk profile and user trust.

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

8 findings rated critical or high. Fix these first.

  1. 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

  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"

      • 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';…

  3. 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

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

Project Leonardo occupies a specialized niche as a hosting provider for online libraries distributing free arts and science content. Its competitive advantage lies in optimizing server locations and configurations to comply with varying international copyright laws. The business model is service-oriented, focusing on infrastructure support rather than content creation. Revenue streams are likely limited or non-commercial, given the free content focus. The target customers are online libraries and their users. The partnership ecosystem includes IMSLP-EU, PML-CA, and IMSLP Forums, indicating a collaborative network. Growth indicators are modest, with a stable domain age and consistent service offering. Strategic observations suggest potential for modernization and enhanced security to maintain trust and compliance.

Security posture

The current security maturity level is basic. The domain registration is solid with clientTransferProhibited status, but DNSSEC is not enabled. The website lacks HTTPS enforcement and security headers such as Content-Security-Policy or X-Frame-Options. No vulnerability disclosure or incident response information is provided. Data protection practices are minimal, with no cookie consent or privacy compliance mechanisms evident. The absence of security policies and contact channels for security incidents indicates limited incident response readiness. Overall, the security culture appears informal and could be improved by adopting standard best practices and compliance frameworks.

Recommendations

  1. Enable HTTPS with HSTS and ensure all site content is served securely.
  2. Implement DNSSEC to protect domain name resolution from spoofing.
  3. Add security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  5. Establish and publish an incident response policy with dedicated security contact information.

Technical notes

Notes

The website is built using basic HTML and CSS without modern frameworks or CMS platforms. There is no evidence of JavaScript libraries or analytics tools. The site design is minimal and not optimized for mobile devices or accessibility standards. Performance is likely moderate due to simplicity but could be improved with modern techniques. The hosting provider is not explicitly identified, but server locations are optimized for copyright compliance. Technical debt is low due to simplicity but modernization opportunities exist to improve security, privacy, and user experience.
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.
