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

Sketch is a well-established design software company targeting designers and creative professionals with a macOS native application focused on design, prototyping, collaboration, and developer handoff. The website is professionally designed, rich in content, and demonstrates a mature digital presence with modern technologies and privacy-conscious analytics. Security posture is strong with HTTPS and security headers, though explicit security policies and incident response information are not publicly detailed. WHOIS data is unavailable or privacy protected, which slightly reduces trust but is common for established brands. Overall, Sketch presents a trustworthy and professional business with a strong market position in the design software industry.

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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

    • High

      Third-party services without privacy policy

      Detected services: LinkedIn, YouTube

      What to do: Document all third-party data sharing in your privacy policy

  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

Sketch operates in the technology sector providing a specialized design toolkit for macOS users. Its business model revolves around software licensing with free trials and paid subscriptions. The company enjoys a strong market position supported by industry awards and a loyal user base. The website highlights collaboration and developer handoff as key differentiators. The presence of a dedicated community forum and extensive resources indicates a robust ecosystem. No direct contact emails or phone numbers are publicly displayed, suggesting a preference for controlled communication channels via support forms.

Security posture

The website enforces HTTPS and implements multiple security headers, indicating a good security baseline. Use of Sentry for error monitoring shows proactive operational security. However, the absence of a published security policy, incident response plan, or vulnerability disclosure program limits transparency. No security contact emails were found. There is no evidence of exposed sensitive data or vulnerable libraries. Overall, the security posture is solid but could be improved by publishing formal security documentation and contact channels.

Recommendations

  1. Publish a dedicated security policy and incident response page to enhance transparency.
  2. Implement and publicize a vulnerability disclosure program or security.txt file.
  3. Provide direct security contact information (e.g., security@sketch.com) for reporting issues.
  4. Enhance privacy compliance disclosures with explicit data retention policies.
  5. Consider publishing data protection officer contact details if applicable.

Technical notes

Notes

The website uses a modern tech stack including JavaScript frameworks (StimulusJS), video embedding via WebAssembly components, and privacy-focused analytics (Simple Analytics). It is optimized for performance and mobile devices, with good SEO and accessibility practices. The site uses multiple preconnect and preload hints for resource optimization. Hosting and CMS details are not explicitly identified but the site is well-structured and fast loading. There is no indication of technical debt or outdated technologies. Opportunities exist to improve technical transparency around hosting and backend infrastructure.
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.
