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

4 findings rated critical or high. Fix these first.

  1. 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

  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

  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

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

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

Leadfeeder operates in the technology sector with a focus on sales and marketing enablement. Its business model is subscription-based with tiered pricing depending on the number of companies identified monthly. The company emphasizes data quality, GDPR compliance, and integration capabilities. Its partnership with Dealfront and integrations with platforms like Salesforce, Hubspot, and Google Ads enhance its ecosystem. The company targets medium-sized businesses and enterprises seeking to optimize lead generation and sales prospecting. The presence of extensive resources, customer testimonials, and a free trial indicates a customer-centric approach and strong market positioning.

Security posture

The website employs modern SSL/TLS protocols (TLS 1.3 and 1.2) with strong cipher suites and no known vulnerabilities such as Heartbleed or Logjam. However, it lacks certain security best practices including HSTS enforcement, OCSP stapling, DNSSEC, and DMARC records. Security headers are minimal or not detected. The site uses reputable hosting (AWS) and integrates security-conscious third-party tools like CookieHub for consent management. Overall, the security posture is good but could be enhanced by implementing additional HTTP security headers and DNS security features to mitigate risks and improve trust.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS.
  2. Implement OCSP stapling to improve SSL certificate revocation checking performance and security.
  3. Deploy DNSSEC to protect against DNS spoofing and ensure DNS integrity.
  4. Add a DMARC record to enhance email security and prevent phishing.
  5. Enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection.

Technical notes

Notes

The website is hosted on AWS with DNS managed by Amazon Route 53. It uses a modern tech stack including JavaScript, Visual Website Optimizer for A/B testing, Google Tag Manager, and CookieHub for cookie consent. The site loads slowly (over 25 seconds) with a large page size (~630 KB) and many resources (107). Mobile optimization is good with responsive design and font preloading. SEO is well addressed with meta tags, Open Graph, and JSON-LD structured data. Accessibility is basic but present. The site uses multiple external integrations and tracking scripts, indicating a mature digital marketing infrastructure.
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.
