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

忆海收录网 is a Chinese SEO and website promotion platform launched in 2023 by 上海鱼我同行科技有限公司. The platform offers automated link exchange, website inclusion services, soft article publishing, and self-service advertising to help webmasters increase traffic and improve search engine rankings. The target audience primarily consists of webmasters and SEO professionals seeking to boost their website visibility through backlinking and content promotion. The business operates as a small-scale technology service provider within the SEO and digital marketing niche in China. Technically, the website uses a custom or unknown CMS with a frontend built on HTML5, CSS3, JavaScript, jQuery, and the Layui UI framework. It is hosted via DNSPod, Inc., with HTTPS enabled but lacks advanced security headers and DNSSEC. Performance and mobile optimization are basic, and SEO practices are moderate with meta tags and structured navigation. Analytics are implemented using Baidu Analytics, indicating moderate user tracking without visible privacy compliance mechanisms. From a security perspective, the site has a basic SSL configuration but lacks DNSSEC and security headers such as CSP or HSTS. Forms do not show explicit anti-bot or CSRF protections, which could expose the site to automated abuse or injection risks. No privacy or cookie policies are present, indicating compliance gaps with GDPR or similar regulations. The domain registration is recent but consistent with the business's founding date and scope, registered through a reputable registrar without privacy protection. Overall, the website is functional and moderately credible for its niche but requires improvements in privacy compliance, security hardening, and transparency of contact information to enhance trustworthiness and regulatory adherence. Strategic recommendations include implementing privacy and cookie policies, enabling DNSSEC, adding security headers, and improving form security measures.

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 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

    • 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.

Business context

Business profile

忆海收录网 operates as a niche SEO and link exchange platform targeting Chinese webmasters and digital marketers. Its business model revolves around providing automated backlinking and website inclusion services to increase site traffic and search engine rankings. Revenue streams likely include paid soft article publishing and self-service advertising. The company is small-sized and relatively new, founded in 2023, with no publicly listed subsidiaries or parent companies. The platform leverages partnerships such as pay.yihaiquanyi.com for payment processing. Competitive advantages include automation of link exchange and a broad database of indexed websites and articles. Growth indicators include active content publishing and user engagement metrics displayed on the site. However, the lack of comprehensive privacy and security policies may limit expansion into regulated markets.

Security posture

The website demonstrates a basic security posture with HTTPS enabled but lacks critical security headers and DNSSEC, which are important for domain and transport security. The absence of privacy and cookie policies indicates compliance gaps with data protection regulations such as GDPR. Forms on the site do not show visible anti-CSRF or anti-bot protections, increasing risk of automated abuse. No incident response or security contact information is provided, limiting transparency and readiness for security events. The domain registration is consistent and not privacy-protected, which supports legitimacy but also requires better security controls. Overall, the security maturity is low to moderate, with significant room for improvement in policy, technical controls, and transparency.

Recommendations

  1. Implement a comprehensive privacy policy and cookie consent mechanism to improve compliance and user trust.
  2. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  3. Add essential security headers such as Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options.
  4. Incorporate CAPTCHA or other anti-bot measures on forms to prevent automated abuse and spam submissions.
  5. Publish clear incident response and security contact information to improve transparency and readiness.

Technical notes

Notes

The website uses a modern frontend stack with HTML5, CSS3, JavaScript, jQuery, and the Layui UI framework, indicating moderate technical maturity. Hosting is provided by DNSPod, a reputable provider. The site is served over HTTPS but lacks advanced security configurations such as DNSSEC and security headers. Performance is moderate with basic mobile optimization and accessibility features. SEO is supported by meta tags and structured navigation but could be enhanced with additional semantic markup and structured data. The CMS appears custom or unknown, which may pose maintenance and security challenges. Analytics are implemented via Baidu Analytics, reflecting regional targeting. Overall, the technical infrastructure is functional but could benefit from modernization and security hardening.
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.
