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

Carrd Inc. operates a popular freemium SaaS platform that enables users to build simple, fully responsive one-page websites. Founded in 2015 and based in the US, Carrd targets individuals and small businesses seeking an easy-to-use website builder with optional Pro features such as custom domains, forms, and payment integrations. The platform enjoys a strong market position in the niche of one-page site builders, offering a clean, professional user experience with consistent branding and good content quality. Technically, the website is built on modern web standards with HTML5, CSS3, and JavaScript, leveraging Cloudflare DNS and a reputable registrar. The site is fast, mobile-optimized, and SEO-friendly, though no major frameworks or CMS were detected, indicating a custom-built solution. Security posture is solid with HTTPS enforced and domain lock statuses, but lacks DNSSEC and security headers. Privacy compliance is partial with a privacy policy present but no cookie consent mechanism or GDPR explicit indicators. Contact is available via a web form but no direct emails or phone numbers are published. Overall, the site is trustworthy and professional with room for improvement in security and privacy transparency.

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 freemium SaaS with revenue generated from Pro subscriptions priced at $19/year. The company leverages partnerships with multiple email marketing and payment service providers to enhance its offering. Its target customers are individuals and small businesses needing simple landing pages or profiles. The platform's competitive advantage lies in its simplicity, responsive design, and low cost. The company maintains a small size with focused operations and no public subsidiaries or parent company. The ecosystem includes integrations with major marketing and payment platforms, enhancing its value proposition. Growth indicators include a mature domain age and consistent branding. Strategic observations suggest potential to expand compliance and security features to increase enterprise adoption.

Security posture

Carrd demonstrates a moderate to strong security posture with HTTPS enforced and domain status locks preventing unauthorized transfers or deletions. However, the absence of DNSSEC and security headers such as Content-Security-Policy or Strict-Transport-Security reduces defense-in-depth. No vulnerability disclosures or incident response contacts are published, which may limit transparency and responsiveness. The lack of cookie consent mechanisms may expose the company to GDPR compliance risks. No exposed sensitive data or vulnerable libraries were detected. Overall, security practices are adequate for the business scale but could be enhanced to meet higher compliance standards and improve user trust.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to harden the web application.
  3. Publish a formal security policy and provide incident response contact information to improve transparency and trust.
  4. Add a cookie consent banner or mechanism to comply with GDPR and other privacy regulations.
  5. Consider adding direct company contact emails and phone numbers to improve customer support accessibility.

Technical notes

Notes

The website is built with modern web technologies including HTML5, CSS3, and JavaScript, served with Cloudflare DNS and a reputable registrar MarkMonitor. The site is fast loading and fully responsive with excellent mobile optimization and good accessibility features. No major CMS or frameworks were detected, indicating a custom-built platform optimized for performance. SEO is well addressed with proper meta tags and Open Graph data. The site uses multiple third-party integrations for forms, payments, and analytics, which are industry-standard and reputable.

Overall, the technical infrastructure is solid and supports a high-quality user experience.
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.
