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

The website sz-isp.com represents a professional telecommunications service provider specializing in SD-WAN, cloud dedicated lines, international dedicated lines, and network acceleration services. The company targets medium to large enterprises, especially those with cross-regional operations, offering flexible, intelligent, and high-quality network solutions. The business is well-established, founded in 2000, with a domain registered since 2012, and maintains partnerships with major Chinese telecom operators such as China Unicom, China Telecom, and China Mobile. Technically, the website employs common web technologies including jQuery, Owl Carousel, WOW.js, and Baidu Analytics. The site is mobile-optimized with good navigation and content relevance, though it loads multiple versions of jQuery which could pose security risks. The hosting provider is not explicitly identified, but the domain registrar is a Chinese digital technology company. SEO and accessibility are basic to good, with room for improvement in security headers and privacy compliance. From a security perspective, the site lacks DNSSEC, security headers, and explicit security or incident response policies. The use of outdated JavaScript libraries and absence of privacy and cookie policies indicate compliance gaps. However, no critical vulnerabilities or malware indicators were found. The domain registration details align well with the business claims, supporting legitimacy. Overall, the website presents a credible and professional business presence with moderate technical maturity and security posture. Strategic improvements in privacy compliance, security best practices, and technology stack modernization are recommended to enhance trust and reduce risk.

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

8 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

The company operates in the telecommunications sector, focusing on SD-WAN and enterprise network services. It leverages a broad network infrastructure with over 2000 PoP points globally, serving industries such as manufacturing, finance, and trade. The business model centers on providing managed network solutions and cloud connectivity, targeting medium-sized enterprises and above. Partnerships with major telecom operators strengthen its market position. The website content and partner logos indicate a solid ecosystem and industry recognition. Growth indicators include recent news updates and a diverse product portfolio. Revenue streams likely derive from network service subscriptions and customized enterprise solutions.

Security posture

The security maturity level is moderate. The website uses HTTPS (assumed but not explicitly confirmed), but lacks DNSSEC and security headers, which are important for protecting against DNS spoofing and common web attacks. The presence of multiple outdated jQuery versions increases the risk of client-side vulnerabilities. No privacy or cookie policies are published, indicating compliance gaps with GDPR and other regulations. Incident response and security contact information are absent, limiting transparency. No exposed sensitive data or known vulnerabilities were detected in the HTML content. Overall, the security posture requires enhancements in policy transparency, technical controls, and library updates to reduce risk and improve compliance.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Consolidate and update JavaScript libraries, especially jQuery, to the latest secure versions.
  3. Implement comprehensive privacy and cookie policies with clear user consent mechanisms to improve compliance.
  4. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to harden the website against common attacks.
  5. Publish incident response and security contact information to improve transparency and readiness.

Technical notes

Notes

The website uses a traditional web technology stack with jQuery, Owl Carousel, and WOW.js for UI effects and interactivity. It includes Baidu Analytics and Baidu Share for tracking and social sharing. The site is mobile responsive and has good navigation clarity. However, loading two versions of jQuery is inefficient and potentially insecure. No modern frameworks like React or Angular are detected. The hosting environment is not clearly identified. Performance is moderate, with potential improvements by optimizing scripts and assets. SEO is supported by meta tags and structured navigation but could benefit from enhanced accessibility features and semantic HTML 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.
