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

NutEmail is a Chinese-based personal email service provider operated by Shenzhen Qianke Network Technology Co., Ltd. The company offers cloud-based email solutions emphasizing mobile accessibility, strong anti-spam and anti-virus capabilities, distributed cluster architecture for data redundancy, and bank-grade cloud data security. Their target audience includes individual users and small to micro enterprises seeking efficient and secure email management. The website presents a professional image with clear service descriptions, team introductions, and customer testimonials, positioning NutEmail as an emerging player in the cloud email service market. Technically, the website leverages modern frontend technologies such as Bootstrap 4, jQuery, and slick sliders, ensuring a responsive and user-friendly experience. However, there is no evidence of a CMS or backend platform disclosed. Performance is moderate with good mobile optimization but lacks advanced SEO and accessibility features. The site uses a secure POST method for its contact form but lacks visible anti-spam mechanisms. From a security perspective, the absence of WHOIS data for the domain raises concerns about domain legitimacy and ownership transparency. No privacy or cookie policies are present, and no security headers or HTTPS status information is available, indicating potential compliance and security gaps. While the site content is safe and business-focused, the lack of explicit security and privacy measures reduces overall trustworthiness. Overall, NutEmail demonstrates a solid business concept and technical foundation but requires improvements in domain registration transparency, security best practices, and privacy compliance to enhance its credibility and reduce risk exposure.

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

7 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 Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

NutEmail operates in the technology sector, specifically cloud-based personal email services. The company leverages a SaaS business model targeting individual and small business users in China. Their competitive advantage lies in mobile integration, distributed data storage, and strong anti-spam and anti-virus features. The company maintains a broad partnership ecosystem as evidenced by numerous linked domains in their footer, suggesting collaboration with related service providers. Revenue streams likely include subscription fees for email services and potential value-added features such as shared cloud storage. Growth indicators include a professional website with customer testimonials and a team with diverse expertise. However, the lack of transparent domain registration and privacy policies may hinder trust and market expansion. Strategic partnerships and enhanced compliance could improve market position.

Security posture

The current security posture of NutEmail's website is moderate but with notable deficiencies. The site uses a secure POST method for its contact form, which is positive, but lacks visible HTTPS confirmation and security headers such as Content-Security-Policy or X-Frame-Options. The absence of WHOIS data for the domain is a significant red flag, impacting trust and raising questions about domain ownership. No privacy or cookie policies are present, indicating potential GDPR and other regulatory compliance gaps. There is no evidence of incident response or vulnerability disclosure mechanisms. Overall, while the site content and services emphasize security features, the web presence itself requires enhancements in security best practices, transparency, and compliance to reduce risk and improve user trust.

Recommendations

  1. Implement HTTPS with a valid SSL/TLS certificate and verify secure configuration.
  2. Publish comprehensive privacy and cookie policies to comply with GDPR and other regulations.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  4. Obtain and publish clear WHOIS domain registration information to improve legitimacy and trust.
  5. Establish and communicate incident response and vulnerability disclosure policies.

Technical notes

Notes

The website is built using Bootstrap 4 and jQuery 3.5.1, with additional libraries like Slick Slider and Magnific Popup for UI enhancements. The frontend is responsive and mobile-optimized, providing a good user experience. However, there is no indication of a backend CMS or hosting provider. Performance is moderate with no advanced SEO or accessibility features detected. The contact form uses POST method but lacks visible anti-spam or CAPTCHA protections. The site links to numerous external partner domains, indicating a broad ecosystem but no direct integration with analytics or tracking services. Technical risks include lack of HTTPS confirmation and missing security headers, which could expose users to interception or attacks. Modernization opportunities include adding security best practices, improving SEO, and enhancing accessibility.
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.
