With over 205,000 customers worldwide and a history dating back to 2007, SuperSaaS holds a strong market position emphasizing customization and flexibility over simpler competitors.

Technically, the website employs modern JavaScript frameworks and integrates with popular services such as Google Analytics, PayPal, Stripe, Twilio, and Zoom.

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. 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

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

SuperSaaS operates in the competitive online scheduling market with a focus on flexibility and customization, differentiating itself from simpler platforms like Calendly. Its business model is subscription-based SaaS with a free tier and paid plans, appealing to small to medium businesses across various sectors including health, education, wellness, and public services. The company leverages integrations with major payment processors and communication platforms to enhance its offering. The presence of multiple language versions and a large customer base indicates a global reach. The company maintains a strong digital presence with active social media channels and a regularly updated blog, supporting customer engagement and brand awareness.

Security posture

The website demonstrates a mature security posture with HTTPS enforced and secure integration of payment and communication services. No sensitive data is exposed in the HTML content, and cookie consent mechanisms are implemented to comply with privacy regulations. However, the absence of explicit security headers such as X-Frame-Options and X-Content-Type-Options, and lack of a published security policy or incident response contact, represent areas for improvement. No vulnerability disclosure or security.txt file was found, which could hinder responsible vulnerability reporting. Overall, the platform appears secure but could benefit from enhanced transparency and formalized security documentation.

Recommendations

  1. Implement and explicitly configure security headers including X-Frame-Options and X-Content-Type-Options to mitigate clickjacking and MIME sniffing risks.
  2. Publish a dedicated security policy page detailing security practices, data protection measures, and incident response procedures.
  3. Create and maintain a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  4. Enhance transparency on data retention and processing policies to strengthen GDPR compliance and user trust.
  5. Regularly audit third-party scripts and integrations to ensure no vulnerable libraries or tracking abuses are present.

Technical notes

Notes

The website uses a modern JavaScript-based front end with asynchronous loading of analytics and tracking scripts, including Google Tag Manager and multiple analytics platforms. It integrates with payment providers PayPal and Stripe, communication services Twilio and Zoom, and supports calendar synchronization with Google and Microsoft 365. The site is mobile-optimized with responsive design and accessible navigation. Performance appears fast with efficient resource loading. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting provider details are not disclosed. The technical implementation is robust with opportunities to improve security header coverage and formalize security 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.
