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

Linkdex is a UK-based technology company operating under Analytics SEO Limited (t/a Authoritas), providing a comprehensive SEO platform tailored for professional marketers, agency teams, and in-house SEO teams. The platform offers extensive SEO data, content marketing insights, outreach strategy tools, ranking intelligence, and project management capabilities. The company positions itself as a trusted partner for global agencies and enterprises, supported by a professional website with strong branding and client endorsements. Technically, the website is built on WordPress with modern frameworks such as React and Bootstrap, integrating key marketing and analytics tools like Google Analytics, Google Tag Manager, and Intercom. The site demonstrates good mobile optimization, SEO practices, and user experience, though performance is moderate and accessibility is basic. From a security perspective, the site enforces HTTPS and employs secure forms but lacks visible security headers and explicit cookie consent mechanisms, indicating areas for improvement in compliance and security hardening. The absence of WHOIS data for the domain is a notable anomaly that slightly reduces trustworthiness but does not negate the professional presence and business legitimacy evident on the site. Overall, Linkdex presents a solid business and technical profile with minor gaps in privacy compliance and security best practices. Strategic enhancements in these areas would strengthen its market position and trustworthiness.

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

6 findings rated critical or high. Fix these first.

  1. 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

  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

Linkdex operates in the competitive SEO technology sector, targeting professional marketers and agencies with a SaaS model. Its competitive advantage lies in unique data offerings such as the Author Search Engine and comprehensive SEO forecasting tools. The company leverages partnerships and a strong client base including recognized brands, enhancing its market credibility. The business model focuses on subscription-based access with demos and trials to drive adoption. Growth indicators include multi-market support (UK, US, Taiwan) and ongoing feature development. The parent company Analytics SEO Limited anchors the corporate structure, suggesting stability and potential for expansion.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enforced and no visible sensitive data exposure. However, the lack of security headers such as Content-Security-Policy and absence of a published security policy or incident response contacts indicate gaps in security governance. No vulnerability disclosures or security.txt files were found, limiting transparency. The missing cookie consent mechanism may pose GDPR compliance risks. Overall, the security posture is adequate for business operations but would benefit from formalized policies, enhanced header configurations, and improved privacy controls to mitigate regulatory and operational risks.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Add a clear cookie consent banner and mechanism to ensure GDPR compliance and improve user privacy transparency.
  3. Publish a formal security policy and incident response contact information to build trust and readiness for security events.
  4. Consider establishing a vulnerability disclosure program and hosting a security.txt file to encourage responsible reporting and improve security posture.
  5. Regularly audit and update third-party libraries and plugins to minimize vulnerabilities and maintain technical hygiene.

Technical notes

Notes

The website is built on a WordPress CMS platform enhanced with React components and Bootstrap styling, indicating a hybrid modern architecture. It uses standard web analytics and marketing tools such as Google Analytics, Google Tag Manager, and Intercom for user engagement and tracking. The site loads moderate resources and shows good mobile responsiveness but could improve accessibility features. The absence of explicit hosting provider data limits infrastructure insights. Overall, the technical implementation supports business goals effectively but has room for optimization in performance and security configurations.
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.
