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

2 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 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

  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

Crowdin operates in the technology sector focusing on localization and translation management solutions. Its SaaS business model targets software development teams, marketing departments, support teams, designers, and freelance translators. The company leverages AI to improve translation quality and efficiency, differentiating itself in a competitive market. Crowdin's extensive integration ecosystem and continuous localization capabilities provide competitive advantages. The company maintains a medium-sized workforce and is headquartered in Estonia. Its market positioning is strong, supported by a broad customer base and positive testimonials. Crowdin actively engages with its community via social media and offers rich educational resources, enhancing customer engagement and brand loyalty.

Security posture

Crowdin demonstrates a mature security posture with enforced HTTPS, use of AWS WAF for web application firewall protection, and CAPTCHA challenges to mitigate automated threats. The site includes security headers such as HSTS, X-Frame-Options, and Content-Security-Policy, which help prevent common web vulnerabilities. Error monitoring via Sentry indicates active incident detection capabilities. However, the absence of a public security policy, incident response plan, or vulnerability disclosure program represents a compliance gap. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Privacy policies are comprehensive and GDPR aligned, reflecting good data protection practices. Overall, Crowdin's security posture is strong but could be improved by formalizing security governance documentation and communication.

Recommendations

  1. Publish a dedicated security policy and incident response page on the website to improve transparency and compliance.
  2. Implement and publicly disclose a vulnerability disclosure program and security.txt file to encourage responsible reporting.
  3. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing attacks.
  4. Provide explicit contact channels for security incidents such as security@ or abuse@ email addresses.
  5. Regularly audit and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.

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.
