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 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 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

The company targets Squarespace website owners and designers seeking to overcome design limitations without coding. Its subscription-based model offers a 14-day free trial and tiered plans, catering to individuals and agencies. The business leverages partnerships with payment processors and environmental organizations, enhancing brand credibility. The content strategy includes a regularly updated blog with relevant Squarespace insights, supporting customer education and SEO. The company maintains a consistent brand image and actively uses social media channels for engagement. Growth indicators include monthly feature releases and active user tracking via analytics platforms.

Security posture

The website exhibits a solid security foundation with enforced HTTPS and HSTS headers, mitigating common web threats. No exposed sensitive data or vulnerable libraries were identified in the HTML content. The use of third-party analytics and marketing scripts is standard but should be regularly audited to prevent supply chain risks. The absence of explicit security policies and incident response contacts suggests an area for improvement in transparency and readiness. Privacy compliance is basic, lacking detailed GDPR statements or cookie management options beyond a simple banner. Overall, the security maturity is good but could benefit from enhanced policy disclosures and incident handling mechanisms.

Recommendations

  1. Publish comprehensive privacy and cookie policies with explicit GDPR compliance details.
  2. Add a terms of service page to clarify user agreements and legal protections.
  3. Provide direct company contact emails and phone numbers for support and security reporting.
  4. Implement a security policy and incident response contact information to improve transparency.
  5. Regularly review and update third-party scripts to mitigate potential vulnerabilities.

Notes

The website is built on Squarespace 7.1, utilizing its native CMS capabilities combined with advanced JavaScript libraries such as GSAP for animations and Mixpanel for analytics. Hosting is provided by Squarespace's CDN, ensuring fast load times and global availability. The site is mobile-optimized with responsive design and accessibility considerations. SEO is supported through proper meta tags, Open Graph, and structured data (JSON-LD). The technical implementation is modern and robust, with no major technical debt or performance bottlenecks observed. Opportunities exist to enhance privacy and security disclosures and to streamline third-party integrations.
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.
