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

MasterGo is a Chinese technology company offering an AI-driven digital interface production platform aimed at designers and product teams. The platform focuses on enhancing digital product design and collaboration through modern SaaS tools. The website is professionally designed with a modern UI framework and hosted on Alibaba Cloud, indicating a solid technical infrastructure. However, the site lacks visible privacy and cookie policies, contact information, and security headers, which are critical for compliance and trust. The domain is well-established since 2002, supporting the legitimacy of the business. Overall, the security posture is weak due to missing security best practices, and privacy compliance is minimal. Strategic improvements in security policies, privacy disclosures, and incident response contacts are recommended to enhance trust and compliance.

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 operates in the competitive digital design SaaS market, targeting Chinese-speaking designers and product teams. Its AI integration positions it as an innovative player in the technology sector. The business model is subscription-based SaaS, focusing on collaboration and interface design. The company benefits from a long-established domain and hosting by a reputable cloud provider. However, the lack of visible certifications, trust signals, and contact information may limit customer confidence. There is no evidence of partnerships or subsidiaries from the provided data. Growth potential exists if compliance and security transparency are improved.

Security posture

The website currently exhibits a low security maturity level. There are no detected security headers, no DNSSEC enabled, and no published security or incident response policies. The absence of privacy and cookie policies indicates compliance gaps with GDPR and other data protection regulations. No vulnerability disclosure or security.txt files were found, limiting transparency for security researchers. The domain is secured with HTTPS (implied but not explicitly confirmed), but SSL configuration details are unknown. The site should implement standard security headers, enable DNSSEC, publish privacy and cookie policies, and provide clear incident response contacts to improve security posture and compliance readiness.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add standard security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Enable DNSSEC on the domain to enhance DNS security.
  4. Provide clear contact information including security incident response and data protection officer contacts.
  5. Conduct a security audit to identify and remediate any vulnerabilities and improve SSL/TLS configuration.

Technical notes

Notes

The website uses a modern frontend stack with Element UI components and the Inter font family, likely built on Vue.js. Hosting is provided by Alibaba Cloud, a major cloud provider in China, ensuring reliable infrastructure. Performance appears moderate with good mobile optimization and basic accessibility features. SEO optimization is basic with proper viewport meta tags and title. However, no analytics or tracking scripts were detected, which may limit marketing insights. The site lacks CMS identification and does not show signs of common CMS platforms. Technical debt is not evident from the HTML snippet, but the absence of security best practices and compliance documentation indicates areas for modernization and improvement.
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.
