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

Delinian Limited operates as a portfolio company owner specializing in delivering highly targeted data, research, insights, and analytics services across select global markets. The company leverages a portfolio of respected brands and focuses on value creation through investment, growth, and divestment strategies. Their services include profiling, predictive analytics, accreditation, and events, targeting business professionals and enterprises in niche sectors. The company is UK-based with additional presence in New York and is owned by Epiris since 2022. Technically, the website is built on WordPress with modern SEO and analytics tools such as Yoast SEO, Google Tag Manager, and CookieYes for consent management. The site demonstrates good mobile optimization, accessibility, and performance, with a professional design and clear navigation. Security measures include HTTPS enforcement and use of Incapsula and Cloudflare services for protection, although some security headers are missing and no explicit security policy or incident response contacts are published. The security posture is solid with no visible vulnerabilities or exposed sensitive data, but improvements are recommended in publishing security policies and enhancing HTTP security headers. Privacy compliance is well addressed with comprehensive cookie and privacy policies and a consent mechanism. Business credibility is supported by clear contact information, professional content, and trust indicators such as LinkedIn presence and company registration details. Overall, the website is trustworthy and professionally maintained, with moderate to high scores in content quality, technical implementation, security, privacy compliance, and business credibility. The lack of WHOIS data reduces domain trust slightly but is mitigated by consistent business information and verifiable company registration.

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

3 findings rated critical or high. Fix these first.

  1. 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';…

  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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • 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

Delinian holds a strong market position as a portfolio owner of specialized data and insights companies, focusing on sectors within the media and business intelligence industries. Their competitive advantage lies in owning respected brands with proprietary data and deep sector knowledge. The business model revolves around investing in, growing, and divesting portfolio companies to maximize value. Revenue streams likely include data services, accreditation, events, and analytics products. Target customers are enterprises and professionals requiring specialized market insights. The company shows growth through recent divestments and acquisitions, indicating active portfolio management. Partnerships and social presence on LinkedIn support a robust ecosystem and market credibility.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and use of reputable security services such as Incapsula for DDoS protection and Cloudflare Bot Management. Cookie consent mechanisms comply with GDPR requirements, enhancing privacy protection. However, the absence of key security headers like Content-Security-Policy and lack of a published security policy or incident response contacts represent gaps in transparency and defense-in-depth. No vulnerabilities or exposed sensitive data were detected in the analysis. The site would benefit from formalizing incident response procedures and publishing security documentation to improve trust and readiness.

Recommendations

  1. Implement and enforce HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a clear security policy and incident response contact information on the website to improve transparency and facilitate vulnerability reporting.
  3. Regularly audit and update all third-party scripts and plugins to mitigate risks from vulnerable libraries.
  4. Enhance privacy compliance by providing detailed data retention policies and user rights information in the privacy policy.
  5. Consider adding a vulnerability disclosure program or security.txt file to encourage responsible reporting and improve security culture.

Technical notes

Notes

The website is built on a WordPress CMS platform using a custom theme and several plugins including Yoast SEO for search optimization, CookieYes for cookie consent management, and Google Tag Manager for analytics integration. The site loads external resources from trusted CDNs such as Google Fonts, jsDelivr, and unpkg. Performance is moderate with asynchronous loading of scripts and responsive design for mobile devices. Accessibility features such as ARIA labels and semantic HTML are present. The technical stack is modern and well-maintained, though hosting provider details are not explicitly identified. The site uses Incapsula and Cloudflare services for security and bot management, indicating a layered defense approach. Opportunities exist to improve security headers and formalize security documentation.
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.
