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

The website art.755fl.com is an informational platform dedicated to classical art, offering multilingual content including artist profiles, artworks, art movements, and galleries. It targets art enthusiasts and researchers with a niche focus on cultural and historical art content. The business model appears to be content-driven, possibly supported by advertising or partnerships, but lacks explicit commercial or transactional features. Technically, the site uses basic HTML and CSS with no detected CMS or advanced frameworks. The site is moderately optimized for performance and mobile devices but lacks advanced accessibility features. Security posture is basic with HTTPS enabled but no security headers or advanced protections detected. Privacy and compliance policies are absent, and contact information is limited to a contact form without direct emails or phone numbers. WHOIS data is missing, raising concerns about domain legitimacy and registration status. Overall, the site is functional but requires improvements in security, privacy compliance, and business transparency to enhance trust and professionalism.

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

9 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. 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.

    • Critical

      Unable to retrieve SSL certificate

      Could not establish secure connection to retrieve certificate information

      What to do: Check if the server is accessible and SSL/TLS is properly configured

  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 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';…

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 site occupies a niche in the classical art informational space with multilingual reach, which may help attract a diverse audience. However, the lack of clear business identity, contact details, and WHOIS registration data limits credibility. The external links suggest partnerships with related arts and travel domains, but some linked domains appear suspicious and warrant further review. The business model is likely informational and content-based, with no clear revenue streams identified. Growth potential depends on improving trust signals, compliance, and expanding content quality and engagement features.

Security posture

Security maturity is low to moderate. HTTPS is implemented, which is a positive baseline. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and HSTS reduces protection against common web attacks. No privacy or cookie policies are present, indicating compliance gaps with GDPR and other regulations. The site uses a contact form but lacks secure input validation indicators. No incident response or vulnerability disclosure information is available. The missing WHOIS data is a significant risk factor, potentially indicating domain registration issues or privacy protection that is not justified. Overall, the site should prioritize implementing security headers, privacy policies, and improving domain registration transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Strict-Transport-Security.
  2. Publish clear privacy and cookie policies to comply with GDPR and other privacy regulations.
  3. Provide explicit company contact information including verified emails and phone numbers to improve trust.
  4. Investigate and resolve WHOIS registration data absence to ensure domain legitimacy and transparency.
  5. Enhance mobile responsiveness and accessibility to improve user experience and SEO.

Technical notes

Notes

The website is built using basic HTML5 and CSS without detectable modern frameworks or CMS platforms. It serves static content with multilingual support via subdomains. Performance is moderate with lazy loading of images but no advanced optimization techniques detected. The site lacks analytics or tracking scripts, indicating minimal user tracking. There is no evidence of modern JavaScript frameworks or CDN usage. The absence of security headers and privacy policies indicates technical debt in security and compliance areas. Hosting provider and infrastructure details are not discernible from the content. Overall, the technical implementation is functional but basic, with room for modernization and security enhancements.
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.
