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.

Business context

Business profile

Crowdin operates in the technology sector focusing on localization and translation management. Its business model is SaaS-based, targeting medium to large enterprises and teams requiring multilingual content management. The company leverages AI to enhance translation quality and efficiency, differentiating itself in a competitive market. Crowdin maintains a broad partnership ecosystem with over 700 integrations, enhancing its platform's versatility. The company demonstrates growth potential through continuous feature expansion, including AI translation and enterprise offerings with trial periods. Crowdin's market positioning is reinforced by strong branding, customer testimonials, and a consistent digital presence across social media and developer resources. The absence of a parent company or subsidiaries suggests an independent operation focused on core localization services.

Security posture

Crowdin exhibits a mature security posture with enforced HTTPS, multiple security headers, and bot management via Cloudflare. The platform uses CSRF tokens and session management cookies to protect user sessions. Error monitoring with Sentry and analytics with PostHog indicate proactive operational security monitoring. However, the website lacks publicly available detailed security policies, incident response plans, or vulnerability disclosure programs, which are important for transparency and trust. No critical vulnerabilities or exposed sensitive data were detected in the analysis. Privacy compliance is strong, with GDPR-aligned cookie consent and privacy policies. To enhance security posture, Crowdin should consider publishing explicit security and incident response documentation and a security.txt file to facilitate vulnerability reporting.

Recommendations

  1. Enable DNSSEC to improve DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response plan on the website.
  3. Implement and publish a vulnerability disclosure policy or security.txt file.
  4. Regularly audit and update third-party scripts and libraries to mitigate vulnerabilities.
  5. Enhance transparency by listing certifications and compliance attestations if applicable.

Technical notes

Notes

The website is built using modern web technologies including JavaScript, jQuery, and Laravel backend framework. It leverages AWS Cloudfront CDN for fast content delivery and Cloudflare for bot management and security. Analytics and monitoring are implemented with Google Analytics, HubSpot, PostHog, Segment, and Sentry, indicating a comprehensive approach to user behavior tracking and error reporting. The site is mobile-optimized with responsive design and accessibility features. SEO is well implemented with proper meta tags, Open Graph, and JSON-LD structured data. Performance is fast, supported by CDN and optimized assets. Technical risks are minimal, but reliance on multiple third-party scripts requires ongoing security vigilance.
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.
