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

Appcues is a SaaS company specializing in user engagement platforms designed for SaaS businesses. Their platform automates in-app experiences, behavioral emails, and push notifications to enhance product adoption and retention without requiring developer resources. The company is positioned as a mature player in the SaaS user engagement market, targeting go-to-market teams and product managers. The website reflects a professional and consistent brand with excellent content quality and user experience. Technically, the website leverages a modern tech stack including Webflow CMS, multiple analytics and marketing tools such as Google Analytics, Segment, Hotjar, and HubSpot, and employs strong privacy and consent management mechanisms. The site is well optimized for performance, mobile responsiveness, and accessibility. From a security perspective, the site enforces HTTPS, uses security headers, and integrates CAPTCHA for bot protection. However, it lacks publicly available security policies or incident response information, which could be improved. The WHOIS data is unavailable, likely due to privacy protection, which slightly reduces trust but is justified for this business type. Overall, Appcues presents a low-risk profile with strong digital maturity and privacy compliance. Strategic recommendations include publishing explicit security and incident response policies, adding vulnerability disclosure mechanisms, and enhancing transparency on data protection roles.

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. 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. 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 sector, offering tools that help companies scale onboarding, adoption, and retention. Their business model is subscription-based SaaS targeting mid-sized to large SaaS companies. The company demonstrates strong market positioning with notable customer success stories and integrations. Their partnership ecosystem includes major platforms like HubSpot and Segment. Growth indicators include extensive use of marketing and analytics tools and a comprehensive resource library. The company maintains a professional online presence with consistent branding and GDPR-compliant privacy practices.

Security posture

The website exhibits a mature security posture with enforced HTTPS, use of security headers, and integration of CAPTCHA to mitigate automated threats. Privacy compliance is well addressed through detailed cookie consent mechanisms and GDPR-aligned policies. However, the absence of a public security policy, incident response plan, and vulnerability disclosure program represents gaps in transparency and readiness. No vulnerabilities or exposed sensitive data were detected. The domain's WHOIS privacy protection is appropriate but limits external trust verification. Overall, the security posture is good but could be enhanced by publishing more explicit security governance documentation.

Recommendations

  1. Publish a dedicated security policy and incident response plan on the website.
  2. Implement and publicize a vulnerability disclosure or security.txt file to encourage responsible reporting.
  3. Provide contact information for a Data Protection Officer or privacy lead to enhance GDPR transparency.
  4. Regularly audit and update third-party scripts and marketing tools to mitigate supply chain risks.
  5. Enhance user trust by adding visible certifications or compliance badges related to security and privacy.

Technical notes

Notes

The website is built on Webflow CMS and uses a modern, modular tech stack including Segment for analytics integration, Hotjar for user behavior tracking, HubSpot for marketing automation, and multiple ad pixels for retargeting. It employs Cloudflare Turnstile CAPTCHA for bot mitigation and CookieYes for consent management. The site is optimized for fast loading and mobile responsiveness, with good SEO and accessibility features. Hosting appears to be via Webflow's infrastructure with CDN support. Technical risks are minimal, but reliance on multiple third-party scripts requires ongoing security 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.
