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

Appcues is a SaaS platform specializing in user engagement solutions tailored for SaaS businesses. Founded in 2013, it offers a comprehensive suite of tools including in-app messaging, workflows automation, email marketing, push notifications, and analytics to help companies onboard, activate, and retain users effectively. The company positions itself as a trusted partner to over 1,500 scaling SaaS businesses, emphasizing ease of use without requiring developer resources. The website reflects a mature digital presence with strong branding, clear messaging, and extensive resources for customers. Technically, the site leverages modern analytics and marketing technologies such as Google Analytics, Segment, HubSpot, and Hotjar, hosted on Webflow infrastructure, ensuring fast performance and mobile optimization. Security posture is strong with HTTPS, security headers, and no visible vulnerabilities, although public security policies and incident response contacts are not published. Privacy compliance is well addressed with clear privacy and cookie policies and consent mechanisms. WHOIS data is unavailable, likely due to privacy protection, but the overall trust indicators and business maturity suggest legitimacy. Strategic recommendations include publishing a vulnerability disclosure policy, incident response contacts, and pursuing recognized security certifications to further enhance trust and compliance.

NIS2 Art. 21(2)

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

5 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 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';…

  2. 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

  3. 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 Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

Appcues operates in the competitive SaaS user engagement market, targeting product teams and SaaS businesses aiming to improve user activation and retention. Its multi-channel messaging approach and integration with major platforms like Heap, HubSpot, and Segment provide competitive advantages. The business model is subscription-based SaaS, with growth supported by a strong customer base and extensive educational resources such as the Product Adoption Academy. The company’s partnership ecosystem includes analytics and marketing technology providers, enhancing its platform capabilities. Observations indicate a well-structured organization with consistent branding and a focus on customer success. The absence of physical addresses or phone numbers suggests a primarily digital-first operation. The company’s market position is solid, with a focus on product-led growth strategies.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive security headers, and no exposed sensitive data. Use of bot mitigation and analytics scripts is balanced with privacy considerations. However, the lack of publicly available security policies, incident response contacts, and vulnerability disclosure mechanisms represents a compliance gap. There is no evidence of certifications such as ISO 27001 or NIST frameworks, which could enhance trust. The extensive use of third-party scripts necessitates ongoing security audits to mitigate supply chain risks. Overall, the security maturity is good but could be improved by formalizing security governance and transparency.

Recommendations

  1. Publish a formal vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  2. Provide clear incident response contact information to improve transparency and trust.
  3. Pursue recognized security certifications such as ISO 27001 or NIST to demonstrate commitment to security best practices.
  4. Regularly audit and update third-party scripts and integrations to minimize supply chain vulnerabilities.
  5. Enhance privacy disclosures with explicit data retention policies and user rights information.

Technical notes

Notes

The website is built on Webflow CMS and hosting, leveraging a modern tech stack including Google Analytics, Segment, HubSpot, Hotjar, and other marketing and analytics tools. The site is well-optimized for performance and mobile responsiveness, with good accessibility features and SEO optimization. The use of JSON-LD structured data improves search engine understanding and trust signals. Hosting on Webflow and use of CDN services ensures fast content delivery. The technical implementation reflects a mature digital infrastructure suitable for a SaaS company targeting a professional audience. Opportunities exist to further enhance technical robustness by integrating automated security scanning and performance monitoring.
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.
