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

ImgBB is a free image hosting and sharing platform established in 2014, offering users the ability to upload, share, and embed images easily. It targets a broad audience including casual users and forum communities, providing integration solutions such as plugins and APIs. The business model includes a freemium approach with paid Pro accounts that unlock additional features like no ads, direct linking, and larger file size limits. The website is professionally designed with good content quality and consistent branding, supporting multiple languages to cater to an international user base. Technically, ImgBB employs a modern web stack including jQuery and Google Fonts, hosted behind Cloudflare DNS with GoDaddy as the registrar. The site is mobile-optimized and SEO-friendly, though some accessibility features are basic. Performance is moderate, with no major technical debt detected. Security posture is adequate with HTTPS enforced and domain registration locks in place, but DNSSEC is not enabled and security headers are not explicitly present, indicating room for improvement. From a security and compliance perspective, ImgBB provides basic privacy and terms of service documentation but lacks explicit cookie consent mechanisms and security policy disclosures. No direct company contact emails or phone numbers are published, relying on a contact form. No vulnerabilities or malware indicators were detected, and the domain registration data is consistent and trustworthy. Overall, the site is safe for general audiences with no adult or explicit content. Strategically, ImgBB should enhance its security posture by enabling DNSSEC, implementing security headers, and publishing a security.txt file to facilitate vulnerability disclosures. Improving privacy compliance with cookie consent and GDPR indicators would also strengthen trust. These steps will help maintain its market position as a reliable and secure image hosting service.

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

5 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

ImgBB operates in the technology sector as a medium-sized company specializing in free and paid image hosting services. Its competitive advantage lies in offering easy-to-use image upload and sharing tools with API and plugin integrations, appealing to forum users and general consumers. Revenue streams include subscription fees from Pro accounts that provide enhanced features. The company targets a global audience with multilingual support, indicating growth ambitions. The lack of direct contact emails and phone numbers suggests a lean operational model focused on digital engagement. Partnerships or subsidiaries were not identified, implying ImgBB operates independently or under a parent entity not disclosed on the site.

Security posture

The security maturity level of ImgBB is moderate. The site enforces HTTPS and uses domain status locks to protect against unauthorized changes. However, the absence of DNSSEC and security headers such as Content-Security-Policy or X-Frame-Options represents gaps that could expose users to DNS spoofing or clickjacking attacks. No explicit security policies or incident response contacts are published, limiting transparency. The lack of a security.txt file reduces the ease of responsible vulnerability reporting. Compliance with GDPR is not clearly demonstrated, and cookie consent mechanisms are missing. Overall, while no critical vulnerabilities were found, there is room to enhance security controls and compliance documentation.

Recommendations

  1. Enable DNSSEC to secure DNS queries and prevent spoofing.
  2. Implement standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish a security.txt file to facilitate vulnerability disclosure and improve transparency.
  4. Add a cookie consent banner and detailed cookie policy to comply with privacy regulations.
  5. Provide explicit security policy documentation and incident response contact information.

Technical notes

Notes

ImgBB's technical infrastructure is built on a custom web platform using jQuery and Google Fonts, served via Cloudflare DNS and registered through GoDaddy. The website is mobile-optimized with responsive design and good SEO practices. Performance is moderate, with no major issues detected in the HTML or scripts. The absence of a CMS suggests a custom or proprietary solution. The site uses multiple language versions to support international users. Technical risks include lack of DNSSEC and missing security headers, which should be addressed to improve resilience. Overall, the technical implementation supports the business needs effectively but can benefit from modernization in security practices.
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.
