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

1 finding rated critical or high. Fix these first.

  1. 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.

Business context

Business profile

Miro operates in the technology sector, targeting teams and organizations that require collaborative innovation tools. Its business model is SaaS-based, offering a platform that integrates with numerous productivity tools and supports various workflows. The company demonstrates strong growth indicators with a large user base and enterprise adoption. The website highlights key services such as online whiteboards, AI-powered features, and extensive integrations. Miro's partnership ecosystem includes integrations with Microsoft, Google, and Atlassian products. The company maintains a consistent brand presence and provides extensive resources, including templates, developer portals, and educational content.

Security posture

Miro exhibits a mature security posture with enforced HTTPS, multiple security headers, and domain registration protections that prevent unauthorized changes. The use of Sentry for error monitoring and cookie consent mechanisms further enhance security and privacy. However, the absence of DNSSEC and a publicly available vulnerability disclosure or security.txt file indicates room for improvement. Incident response contact channels are not explicitly provided, which could hinder timely communication in case of security incidents. No vulnerabilities or exposed sensitive data were detected in the website content or scripts.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  3. Provide explicit incident response contact information to improve security communication.
  4. Highlight security certifications and compliance frameworks more prominently to build trust.
  5. Continue monitoring and updating third-party libraries to avoid vulnerabilities.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, with Contentful as the CMS and Wistia for video hosting. Hosting is provided by Amazon AWS, ensuring scalability and reliability. Performance is optimized with preloading of fonts and styles, and the site is mobile responsive with good accessibility features. SEO is well addressed with proper meta tags and Open Graph data. The technical implementation reflects a well-maintained and modern infrastructure with minimal technical debt. Opportunities exist to further improve DNS security and incident response readiness.
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.
