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

Semantic Web Company is a technology provider specializing in semantic AI solutions, headquartered in Austria with subsidiaries in the US and UK. They offer the PoolParty Semantic Suite, a leading graph-based platform for text mining, recommender systems, and data fabric solutions, targeting enterprises seeking advanced AI-driven knowledge management. The website is professionally designed with comprehensive content and clear navigation, reflecting a mature digital presence. However, the absence of a valid SSL certificate and HTTPS implementation is a critical security shortfall that undermines trust and data protection. The technical stack is modern, leveraging WordPress with Elementor and various JavaScript libraries, but performance data is lacking, indicating potential optimization opportunities. Privacy compliance is addressed with visible cookie consent and a detailed privacy policy, though analytics tracking is minimally configured. Overall, the business credibility is strong, supported by consistent branding and active social media engagement, but security posture requires urgent improvement to meet industry standards.

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. 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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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. 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

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  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 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 company holds a strong market position in the semantic AI technology sector, providing specialized software products that transform data into actionable knowledge. Their business model focuses on software licensing and AI solution delivery to enterprise clients. The presence of subsidiaries in key markets (US and UK) indicates strategic international expansion. Partnerships, such as with graphwise.ai, suggest an ecosystem approach to technology offerings. The website content and structured data reinforce the company's expertise and leadership in semantic AI. Growth indicators include active research and conference participation. However, the lack of explicit certifications or security policies may limit trust among highly regulated clients.

Security posture

The current security posture is weak due to the lack of HTTPS and valid SSL certificates, exposing users to potential data interception and undermining secure communications. While some security headers like X-Frame-Options and HSTS are present, the absence of modern TLS protocols and strong cipher suites is a significant vulnerability. No incident response or security policy documentation is publicly available, and no vulnerability disclosure or security.txt files are found, indicating limited transparency in security management. The cookie consent mechanism and privacy policy demonstrate some compliance with data protection regulations, but overall security maturity is low. Immediate remediation of SSL/TLS issues is critical to reduce risk and improve trust.

Recommendations

  1. Install and properly configure a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable and enforce modern TLS protocols (TLS 1.2 and TLS 1.3) and strong cipher suites to secure communications.
  3. Implement and publish a formal security policy and incident response plan accessible to users and partners.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting of security issues.
  5. Configure and verify analytics tools properly to ensure privacy compliance and accurate data collection.
Technical notes

Notes

The website is built on WordPress CMS with Elementor page builder, using modern JavaScript libraries and plugins such as Smart Slider 3. Hosting is likely on AWS infrastructure, inferred from DNS nameservers. The site uses Google Fonts and integrates social media links extensively. Performance metrics are missing, suggesting a need for performance monitoring and optimization. Mobile responsiveness is good, and SEO is enhanced by Yoast SEO plugin usage and structured data in JSON-LD format. However, the lack of HTTPS and SSL certificate is a major technical debt and security risk. The site uses caching and minification plugins (WP Rocket) to optimize loading but actual load times are not reported. Accessibility features are basic and could be improved.
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.
