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

Carrd Inc. operates a popular freemium SaaS platform focused on enabling users to build simple, fully responsive one-page websites. The platform targets individuals and small businesses seeking an easy-to-use website builder with a strong emphasis on responsive design and template variety. Carrd's market position is that of a niche leader in one-page site creation, offering both free and paid tiers with advanced features such as custom domains, forms integration, and payment widgets. Technically, the website is built with modern web standards including HTML5, CSS3, and JavaScript, delivering fast performance and excellent mobile optimization. The platform integrates with numerous third-party services for forms, email marketing, and payments, indicating a mature and extensible infrastructure. However, no CMS or specific frameworks were detected, suggesting a custom-built or lightweight solution. From a security perspective, the site enforces HTTPS with Let's Encrypt certificates and avoids exposing sensitive data. However, it lacks several recommended security headers and does not publicly disclose a vulnerability disclosure policy or incident response contacts. Privacy compliance is partially addressed with a comprehensive privacy policy and terms of service, but no cookie consent mechanism was detected, which could be a compliance gap. Overall, Carrd presents a professional, trustworthy, and well-maintained web presence with minor areas for security and privacy improvement. The domain registration data aligns well with the business claims, supporting legitimacy and trustworthiness.

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. 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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

Carrd's business model is a freemium SaaS offering, generating revenue through Pro subscriptions that unlock advanced features like custom domains, forms, and removal of branding. The target customer segments include individuals, freelancers, and small businesses needing simple landing pages or personal profiles. The platform's competitive advantage lies in its simplicity, responsive design, and integration with a wide ecosystem of third-party marketing and payment tools. Growth indicators include a broad template library and active documentation and changelog updates. Partnerships with major email marketing and payment providers enhance its ecosystem and service reliability.

Security posture

Carrd demonstrates a moderate to high security maturity level with enforced HTTPS and no visible sensitive data leaks. The absence of security headers and a formal vulnerability disclosure policy indicates room for improvement in defense-in-depth and transparency. The lack of direct contact emails or phone numbers for security or abuse reporting may hinder incident response effectiveness. Privacy compliance is partially met with clear policies but lacks cookie consent mechanisms. Overall, the security posture is solid for a SaaS platform but could benefit from enhanced security controls and compliance features.

Recommendations

  1. Implement standard security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to improve protection against common web attacks.
  2. Add a cookie consent banner or mechanism to comply fully with GDPR and other privacy regulations.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting and improve transparency.
  4. Provide direct security and abuse contact channels (e.g., security@ or abuse@ email addresses) to enhance incident response readiness.
  5. Regularly audit third-party integrations for security and privacy compliance to maintain platform integrity.

Technical notes

Notes

The website uses a clean, modern tech stack with HTML5, CSS3, and JavaScript, delivering fast load times and excellent mobile responsiveness. No CMS or heavy frameworks were detected, suggesting a custom or lightweight architecture optimized for performance. The site includes meta tags for SEO and Open Graph for social sharing. Integration with numerous third-party services for forms, payments, and analytics indicates a modular and extensible platform. However, the absence of security headers and cookie consent mechanisms highlights technical debt in security and privacy compliance. Hosting provider details are not explicitly available from the HTML content.
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.
