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

2 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.

    • 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. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 in the technology sector, focusing on graph visualization and analysis software. Their business model includes product sales, training, technical assistance, and custom application development. They serve a broad range of industries including finance, manufacturing, aerospace, and IT. The presence of customer testimonials and partner logos indicates a strong ecosystem and market validation. The company targets medium to large enterprises and technical professionals. Their content strategy emphasizes thought leadership and practical use cases, supporting growth and customer engagement. The lack of explicit founding year or parent company information suggests an independent entity with a focused niche.

Security posture

The website demonstrates a good security maturity level with enforced HTTPS and cookie consent compliance. However, it lacks explicit security headers such as Content-Security-Policy and incident response contact details, which are best practices for enterprise-grade security. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of a published security policy or vulnerability disclosure program limits transparency. Overall, the security posture is adequate for a commercial software vendor but could be enhanced by publishing formal security documentation and improving header configurations.

Recommendations

  1. Implement and publish a formal security policy and incident response contact information on the website.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve protection against common web attacks.
  3. Enhance accessibility features to meet recognized standards and improve user experience for all visitors.
  4. Clarify domain registration details and ensure WHOIS information is complete and consistent with business claims to improve trust.
  5. Maintain and regularly update privacy and cookie policies to ensure ongoing GDPR and global privacy compliance.

The site is mobile responsive with good SEO meta tags and structured data (JSON-LD) for enhanced search engine understanding. Performance is moderate, with potential improvements in loading speed by optimizing assets and scripts. The technical implementation is professional and supports a positive user experience, though accessibility could be improved. No deprecated or vulnerable libraries were detected in the provided content.
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.
