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

Sortlist is a Belgium-based company operating a marketing agency matchmaking platform that helps businesses discover and connect with the best marketing agencies tailored to their project needs. The website is professionally designed with consistent branding and good content quality, targeting businesses seeking marketing services. The platform holds a strong market position evidenced by a high aggregate rating and active social media presence. Technically, the site uses modern web technologies including Next.js, React, and integrates multiple analytics and tracking tools such as Google Tag Manager, Radar, and Lead Forensics. The site is mobile optimized and SEO friendly, though accessibility features are basic. Security posture is solid with HTTPS enforced and no visible vulnerabilities, but lacks explicit security headers and published security policies. Privacy compliance is limited due to absence of visible privacy and cookie policies. Overall, the domain registration data aligns well with the business claims, supporting legitimacy 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

10 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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

Sortlist operates in the marketing services sector as an essential business entity providing a platform for agency discovery and project-based matchmaking. Its business model revolves around connecting clients with marketing agencies, likely generating revenue through lead generation or agency partnerships. The company supports multiple European markets with dedicated contact points and phone numbers, indicating a medium-sized operation with regional reach. The platform's competitive advantage lies in personalized agency recommendations and a strong reputation backed by user reviews. The partnership ecosystem includes social media channels and multiple localized domains. Growth indicators include extensive tracking and analytics usage, suggesting data-driven marketing and user engagement strategies.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and no exposed sensitive data detected. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No vulnerability disclosure or incident response policies are published, which could hinder timely handling of security incidents. The extensive use of third-party tracking scripts increases the attack surface and privacy risks. GDPR compliance indicators are weak due to missing privacy and cookie policies. Overall, the security culture appears functional but could be enhanced by formalizing policies and improving header configurations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers including CSP, HSTS, and X-Frame-Options to strengthen browser security.
  3. Establish and disclose a vulnerability disclosure and incident response policy to improve security transparency.
  4. Review and minimize third-party tracking scripts to reduce privacy risks and improve user trust.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on a modern React-based framework (Next.js) with server-side rendering capabilities. It uses asynchronous loading for analytics and tracking scripts to optimize performance. The site is mobile responsive and well-structured with semantic HTML and meta tags supporting SEO. However, no CMS is explicitly detected, suggesting a custom or headless architecture. Hosting provider details are not evident from the content. Performance is moderate, with potential improvements in script optimization and caching. Technical debt appears low but could be reduced by consolidating tracking tools and improving 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.
