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

Leadfeeder is a Finnish-based startup founded in 2013 specializing in B2B lead generation software that helps companies identify and convert website visitors into high-value leads. The company positions itself as a technology-driven SaaS provider focused on buyer intent data and sales intelligence. Their website reflects a professional and consistent brand image, targeting B2B businesses seeking to improve their sales pipeline through data insights. Technically, the website employs modern JavaScript frameworks, Google Tag Manager, and Visual Website Optimizer for analytics and A/B testing, indicating a mature digital infrastructure. Security-wise, the site uses HTTPS and controlled script loading but lacks explicit security policies and headers, suggesting room for improvement in transparency and defense-in-depth. Privacy compliance is partial, with no visible privacy or cookie policies in the analyzed content. Overall, the website is trustworthy and professionally maintained but would benefit from enhanced privacy disclosures and security documentation.

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

2 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.

    • 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

  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

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 SaaS business model focused on B2B lead generation and sales intelligence. Their market positioning leverages buyer intent data to differentiate from generic lead generation tools. The company targets medium to large B2B enterprises looking to optimize their sales funnel. The presence of social media channels and a free trial offer indicates active marketing and customer acquisition strategies. The lack of visible parent or subsidiary companies suggests an independent operation. The use of advanced analytics and A/B testing tools reflects a data-driven approach to product and marketing optimization.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and no visible exposure of sensitive data. The use of Google Tag Manager and Visual Website Optimizer is standard for marketing analytics but requires vigilant management to avoid third-party risks. The absence of explicit security headers and published security or incident response policies indicates gaps in security transparency and maturity. No vulnerability disclosures or security.txt files were found, which could hinder coordinated vulnerability reporting. The site does not appear to be protected by a WAF or show signs of blocking mechanisms, suggesting reliance on other security controls. Overall, the security posture is moderate but could be enhanced by adopting best practices in headers, policies, and incident readiness.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement and disclose a formal security policy and incident response procedures.
  3. Add security headers such as Content Security Policy, HSTS, X-Frame-Options, and X-Content-Type-Options.
  4. Establish a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  5. Regularly audit and update third-party scripts and tracking tools to minimize security risks.

Technical notes

Notes

The website uses modern JavaScript technologies, likely React, combined with Google Tag Manager and Visual Website Optimizer for analytics and experimentation. The site is mobile-optimized with responsive design and good SEO metadata. Performance is moderate, with preloading of CSS and fonts and asynchronous script loading. There is no detected CMS, suggesting a custom or headless architecture. Hosting details are not explicit but scripts and assets are served over HTTPS from reputable CDNs. Technical debt appears low, but the absence of explicit security headers and privacy disclosures indicates areas for modernization and compliance improvements.
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.
