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

6 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
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • 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';…

  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

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

Heyflow operates in the technology sector as a SaaS provider specializing in interactive form creation for marketing and lead generation. The company targets businesses and marketers looking to improve conversion rates through engaging forms. Its business model is subscription-based SaaS with integrations to CRM and analytics platforms, enhancing value for customers. The presence of customer testimonials and market leader usage claims indicate a growing market position. The company is relatively young, founded in 2021, and registered in Indonesia, consistent with the domain registration data. The platform's integration ecosystem, including Zapier and major CRMs, suggests a strategic focus on interoperability and ease of use. The lack of direct contact information on the site may be a strategic choice or an area for improvement to boost customer trust and support responsiveness.

Security posture

The website demonstrates a moderate to good security posture. It uses HTTPS with a valid SSL certificate and Cloudflare DNS, providing baseline protection against common threats. The domain status clientTransferProhibited prevents unauthorized domain transfers. Cookie consent is implemented with granular categories and opt-in/out mechanisms, supporting privacy compliance. However, the absence of DNSSEC reduces DNS security. No advanced security headers (e.g., CSP, HSTS) were detected in the provided data, which could mitigate risks like XSS or clickjacking. There is no visible security policy or incident response contact information, which are best practices for mature security programs. No vulnerabilities or exposed sensitive data were found in the HTML content. Overall, the security posture is adequate for the business type but could be improved with additional security controls and transparency.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to mitigate common web vulnerabilities.
  3. Publish a dedicated security policy and incident response page including contact channels for security issues.
  4. Add a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  5. Consider providing clear company contact information (email, phone) on the website to improve trust and customer support.

Technical notes

Notes

The website is built using modern JavaScript technologies with asynchronous loading of analytics and marketing scripts to optimize performance. It uses Cloudflare for DNS and likely CDN services, contributing to fast load times and reliability. The tech stack includes Google Analytics, Google Tag Manager, Facebook Pixel, Stripe for payments, and Google Maps API, indicating a mature integration ecosystem. The site is mobile-optimized with responsive design and good accessibility features. SEO optimization is basic but present with meta tags and Open Graph data. No CMS was detected, suggesting a custom or proprietary platform. The technical implementation supports a good user experience and scalable infrastructure but could benefit from enhanced security headers and formalized technical documentation.
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.
