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. 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 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Heap operates in the competitive product analytics market with a SaaS subscription model targeting enterprise and large businesses. Their competitive advantage lies in automatic event tracking and AI-driven insights that reveal unknown user behaviors. The company maintains partnerships with analytics and digital experience leaders such as Contentsquare and Hotjar, enhancing their ecosystem. Heap's business model focuses on delivering actionable insights to product and marketing teams, supporting funnel optimization, product adoption, and user behavior analysis. The website content and structure indicate a mature organization with strong branding consistency and trust signals including certifications and customer testimonials. Heap's market positioning as a comprehensive digital insights platform is reinforced by their broad feature set and integration capabilities.

Security posture

Heap exhibits a mature security posture with enforced HTTPS, comprehensive security headers, and adherence to industry standards evidenced by SOC 2 and ISO 27001 certifications. The presence of cookie consent banners and privacy policies indicates compliance with privacy regulations such as GDPR. No vulnerabilities or exposed sensitive data were detected in the website content. However, the absence of a public vulnerability disclosure or security.txt file and explicit incident response contact details suggests areas for improvement in transparency and incident management readiness. Overall, Heap's security practices align well with expectations for a SaaS analytics provider, minimizing risk exposure and supporting customer trust.

Recommendations

  1. Publish a dedicated vulnerability disclosure or security.txt page to facilitate responsible reporting.
  2. Provide explicit incident response contact information to improve transparency and readiness.
  3. Enhance documentation on data retention policies to clarify privacy compliance.
  4. Regularly audit third-party scripts and tracking tools to ensure no privacy or security risks.
  5. Maintain and update security certifications and communicate them clearly to customers.

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.
