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

PromptBase is an online marketplace specializing in AI prompt templates for various AI models such as Midjourney, ChatGPT, Sora, and FLUX. Founded in 2022, it serves a medium-sized audience of AI creators, developers, marketers, and businesses seeking to buy, sell, or hire AI prompt experts. The platform also offers tools for building AI applications and community engagement features. The website is professionally designed with a consistent brand identity and strong trust indicators including extensive positive user reviews and coverage by major media outlets. Technically, the site is built on Angular 18, hosted likely on Google Cloud infrastructure, and uses Google Tag Manager for analytics. It performs well with good mobile optimization and SEO practices. Security posture is solid with HTTPS and domain protection statuses, but lacks advanced security headers and DNSSEC implementation. Privacy compliance is weak due to absence of visible privacy and cookie policies or consent mechanisms. No contact emails or phone numbers are explicitly provided in the analyzed content. Overall, the site is trustworthy and professionally managed but could improve privacy transparency and security hardening.

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 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';…

  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

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

PromptBase occupies a niche market as a dedicated AI prompt marketplace, capitalizing on the growing demand for AI-generated content and prompt engineering. Its business model revolves around facilitating prompt sales, hiring AI creators, and enabling AI app development. Revenue streams likely include commissions on prompt sales and premium services. The platform targets AI enthusiasts, professionals, and enterprises leveraging AI technologies. Its media presence and user base size indicate a strong market position with growth potential. The company appears independent with no parent or subsidiaries identified. Strategic partnerships with media outlets enhance credibility. The absence of explicit contact and compliance information suggests areas for operational maturity improvement.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and domain registration protections in place. However, the lack of DNSSEC and security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents missed opportunities to mitigate common web threats. No vulnerabilities or exposed sensitive data were detected in the provided content. The absence of published security policies or incident response contacts limits transparency and preparedness perception. Privacy compliance is insufficient, lacking GDPR indicators or cookie consent mechanisms. Overall, the security maturity is moderate but can be enhanced to meet best practices and regulatory expectations.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Add security headers (Content-Security-Policy, X-Frame-Options, X-Content-Type-Options) to harden the website against common attacks.
  3. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  4. Provide clear contact information including support and security incident response channels.
  5. Establish and communicate a vulnerability disclosure policy or security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built using Angular 18, indicating a modern single-page application architecture. It leverages Google Tag Manager for analytics and likely uses Google Cloud infrastructure for hosting and DNS services. The site is well-optimized for performance and mobile devices, with responsive design and efficient asset loading. SEO is supported by comprehensive meta tags and Open Graph data. However, no CMS is detected, suggesting a custom or framework-based solution. The absence of accessibility features beyond basic styling indicates room for improvement to meet WCAG standards. Overall, the technical implementation is robust with opportunities for enhanced security and privacy features.
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.
