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

The website bigbigwork.com operates as a comprehensive design inspiration and image search platform primarily targeting designers and creative professionals. It aggregates over 7 billion high-definition images from global design websites, offering free copyright images, AI-powered image enlargement, compression tools, and collaboration features. The platform positions itself as a large-scale resource hub for design materials, supporting multiple languages and providing daily updates with a strong user base exceeding 15 million designers. Technically, the site leverages modern web technologies including Vue.js and Baidu Analytics, delivering fast performance and excellent mobile optimization. Security posture is adequate with HTTPS enforced, though lacking some security headers and formal security policies. Privacy compliance is basic, with a privacy policy present but no cookie consent mechanism detected. WHOIS data is unavailable, which slightly reduces trust but the site’s certifications and business information support legitimacy. Overall, the platform is professional, content-rich, and well-positioned in the media/design sector.

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

11 findings rated critical or high. Fix these first.

  1. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MSSQL

      Port 1433 (MSSQL) is publicly accessible - MSSQL - Database server

      What to do: Immediately restrict access to MSSQL using firewall or VPN

      • NIS2 21(2)(e)

      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection
  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"

    • 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

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 · found on this site
  • 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

Business profile

Bigbigwork.com is positioned as a key player in the design inspiration and image search market, aggregating vast global resources to serve designers and creative teams. Its business model revolves around free access to aggregated content with optional registration, supplemented by proprietary tools such as AI image enlargement and collaboration suites. The company,君库(上海)信息科技有限公司, maintains a portfolio of related products enhancing its ecosystem. The platform’s competitive advantage lies in its extensive image database, multi-language search capabilities, and integration of AI tools. Its target customers include professional designers, agencies, and educational institutions. The presence of testimonials from reputable design firms and educational bodies further strengthens its market credibility. Growth indicators include a large active user base and continuous content updates. Partnerships with related domains and products create a robust service network.

Security posture

The website demonstrates a moderate security maturity level with HTTPS enabled, ensuring encrypted communications. However, the absence of key security headers such as Content-Security-Policy and X-Frame-Options indicates room for improvement in mitigating common web vulnerabilities. No explicit vulnerability disclosure or incident response information is published, which could hinder rapid response to security incidents. Privacy compliance is partial; while a privacy policy exists, cookie consent mechanisms are missing, potentially impacting GDPR adherence. No exposed sensitive data or vulnerable libraries were detected in the analysis. Overall, the security posture is functional but would benefit from enhanced header implementation, formal security policies, and improved privacy controls to align with best practices.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to strengthen defense against common attacks.
  2. Introduce a cookie consent banner and mechanisms to improve GDPR and global privacy compliance.
  3. Publish a clear security policy and incident response contact information to enhance transparency and readiness.
  4. Regularly audit third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Consider WHOIS privacy transparency or domain registration updates to improve trustworthiness and legitimacy perception.

Technical notes

Notes

The website is built on a modern JavaScript framework (Vue.js) with asynchronous loading of scripts and optimized image delivery via OSS processing. It uses Baidu Analytics for user tracking and performance monitoring. The site is well-structured with proper meta tags for SEO and mobile responsive design. Preloading and prefetching techniques are employed to enhance performance. However, no CMS was detected, suggesting a custom or proprietary platform. Hosting details are not explicitly available. The site demonstrates fast loading times and good accessibility features, though some improvements in security headers and privacy mechanisms are recommended. Overall, the technical infrastructure supports a scalable, user-friendly experience suitable for a large user base.
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.
