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

Leadfeeder is a Helsinki-based technology company specializing in B2B lead generation software that identifies companies visiting websites and helps convert them into high-value leads. The company has a mature product with a strong market position, serving over 80,000 users including notable clients like Amazon and Siemens. Their platform integrates with major CRMs and marketing tools, offering comprehensive visitor tracking and lead qualification features. Technically, the website employs advanced analytics, A/B testing, and personalization technologies such as Visual Website Optimizer and Dreamdata, but suffers from slow performance and lacks a valid SSL certificate, which is a critical security concern. Privacy compliance is well addressed with clear policies and consent mechanisms, supporting GDPR requirements. Overall, the business demonstrates strong credibility and professionalism but must urgently address its security posture to maintain trust and compliance.

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

Business profile

Leadfeeder operates in the technology sector, focusing on B2B sales and marketing enablement. Their business model is SaaS-based, offering tiered subscription plans with a free trial. The company targets sales teams, marketers, and agencies seeking to improve lead quality and conversion rates. Their competitive advantage lies in their extensive IP-to-company database, machine learning algorithms for lead identification, and seamless integrations with popular CRMs like Salesforce and HubSpot. The company maintains a robust partnership ecosystem, including dealfront.com, and actively promotes GDPR compliance and data privacy. Growth indicators include a large user base and a comprehensive feature set that appeals to mid-sized enterprises. Their marketing strategy leverages multiple channels, including social media and content marketing, supported by extensive analytics and tracking tools.

Security posture

The website's security posture is currently weak due to the absence of a valid SSL certificate and lack of HTTPS enforcement, exposing users to potential data interception risks. No security headers such as HSTS are implemented, and critical email security records like DMARC are missing. While no active vulnerabilities like Heartbleed or POODLE were detected, the invalid CAA records and lack of OCSP stapling indicate misconfigurations. The site uses multiple third-party scripts and tracking technologies, which require careful management to avoid privacy and security risks. The absence of a documented security policy or incident response plan reduces transparency and preparedness. Immediate remediation is needed to secure communications, implement security best practices, and enhance compliance with data protection regulations.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Implement HTTP security headers including HSTS with preload and includeSubDomains directives.
  3. Configure and validate CAA and DMARC DNS records to improve certificate issuance control and email security.
  4. Enable OCSP stapling and session resumption to improve SSL performance and security.
  5. Develop and publish a comprehensive security policy and incident response plan to enhance transparency and readiness.

Technical notes

Notes

The website is hosted on Amazon AWS infrastructure with multiple A records and AWS nameservers. It uses a modern JavaScript stack with extensive use of third-party analytics and marketing tools such as Google Analytics, Dreamdata, Visual Website Optimizer, and CookieHub for consent management. The site employs advanced A/B testing and personalization frameworks, indicating a high level of digital maturity. However, the page load time is slow (over 13 seconds) with a large page size (~848 KB) and many resources (77), suggesting optimization opportunities. The site is mobile-optimized with responsive design and accessible navigation. No CMS is explicitly detected. The lack of SSL and security headers is a significant technical risk. Overall, the technical infrastructure supports a robust marketing platform but requires performance and security 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.
