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

Linker is a technology company operating a content discovery platform accessible via a secure login portal. The platform targets content creators and businesses seeking efficient content management solutions. The website employs a modern frontend technology stack including jQuery, Bootstrap, AdminLTE, and Chart.js, indicating a moderate level of digital maturity. While the site enforces HTTPS and includes CSRF protection on forms, it lacks several security best practices such as security headers and publicly available privacy or cookie policies. No contact information or detailed business disclosures are present on the login page, limiting transparency. Overall, the site appears legitimate and professionally branded but could improve in privacy compliance and security posture.

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

    • 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

    • 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. 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 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 positions itself as a niche player in the content discovery technology sector, offering SaaS-based services. The business model focuses on subscription or account-based access to its platform. The lack of public business details such as founding year or company registration numbers suggests a small-sized enterprise. The website branding is consistent, but the absence of trust indicators like certifications or testimonials limits credibility. No partnerships or subsidiaries are evident from the data. The platform's target audience includes marketers and content professionals, indicating a B2B focus.

Security posture

The website demonstrates a basic security posture with HTTPS enforced and CSRF tokens implemented on login forms. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap in defense-in-depth strategies. No vulnerability disclosure policy or incident response contacts are published, which could hinder effective security incident management. The login form lacks visible protections against brute force attacks like CAPTCHA or rate limiting. Overall, security practices are adequate but require enhancements to meet higher compliance and protection standards.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to improve browser security.
  2. Publish comprehensive privacy and cookie policies with GDPR compliance statements.
  3. Add contact information and security incident response channels publicly accessible.
  4. Introduce CAPTCHA or rate limiting on login forms to mitigate brute force risks.
  5. Develop and publish a vulnerability disclosure policy and security.txt file to enhance transparency.

Technical notes

Notes

The website uses a combination of popular frontend libraries and frameworks such as jQuery, Bootstrap, AdminLTE, and Chart.js, indicating a modern but standard technology stack. The site loads resources from a dedicated CDN subdomain, which may improve performance. The HTML structure is valid and includes meta tags for viewport and charset, but lacks advanced SEO and accessibility features. Mobile optimization is basic, with responsive design elements present but not fully optimized. No CMS or backend platform is explicitly detected. Performance is moderate with no obvious bottlenecks, but opportunities exist for improvement in SEO and accessibility compliance.
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.
