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

MasterGo is a technology company offering a digital interface production platform tailored for the AI era, primarily targeting designers and digital product teams. The platform emphasizes collaborative design and AI-powered tools to enhance digital interface creation. The website is professionally designed with a modern UI framework and hosted on Alibaba Cloud, reflecting a focus on the Chinese market. However, the site lacks explicit privacy, cookie, and terms of service policies, which are critical for compliance and user trust. Security-wise, HTTPS is enabled, but additional security headers and DNSSEC are not implemented, representing areas for improvement. No contact or incident response information is provided, limiting transparency. Overall, the website is functional and professional but would benefit from enhanced compliance and security disclosures.

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

6 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. 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';…

  3. 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

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

MasterGo positions itself as an emerging SaaS platform in the digital design industry, leveraging AI to differentiate its offerings. The business model focuses on providing tools for interface design and collaboration, targeting medium-sized enterprises and design professionals. The domain age and hosting provider indicate a stable and legitimate operation. The absence of detailed business contact information and certifications suggests a need for improved transparency to strengthen market trust. No evident partnerships or subsidiaries were identified from the content. The platform's growth potential lies in expanding compliance, security posture, and customer engagement channels.

Security posture

The website demonstrates a basic security posture with HTTPS enabled, ensuring encrypted communications. However, the lack of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security reduces its defense-in-depth. No vulnerability disclosures or incident response contacts are published, which may hinder timely security issue reporting and resolution. The absence of privacy and cookie policies also indicates potential compliance gaps with GDPR and other regulations. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Enhancing these areas would significantly improve the security maturity and user trust.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Enable DNSSEC for the domain to protect against DNS spoofing and improve DNS security.
  3. Add standard security headers (CSP, HSTS, X-Frame-Options) to strengthen web security.
  4. Provide clear contact information including security incident response and vulnerability disclosure channels.
  5. Conduct regular security audits and update the website to address any identified vulnerabilities.

Technical notes

Notes

The website uses modern web technologies including the Inter font family and Element UI framework, likely built with Vue.js. Hosting on Alibaba Cloud provides reliable infrastructure consistent with the target market. The site appears moderately optimized for performance and mobile responsiveness. However, SEO and accessibility features are basic and could be enhanced. The absence of analytics and marketing scripts suggests minimal user tracking, which is positive for privacy but may limit marketing insights. Overall, the technical implementation is solid but has room for modernization and compliance improvements.
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.
