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 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

      • 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 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 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

Base Build operates in the blockchain technology sector, focusing on the Ethereum network. Its business model revolves around incentivizing mini app developers through builder rewards and providing analytics to drive app growth. The platform's market positioning is that of an emerging player within the Ethereum ecosystem, aiming to attract developers by offering visibility and financial incentives. Partnerships with related domains such as base.org and base.app indicate a broader ecosystem collaboration. The absence of direct contact information suggests a focus on digital engagement rather than traditional customer support channels. Growth indicators include active reward programs and featured app opportunities. The platform's strategic approach leverages community engagement and data-driven insights to foster adoption and expansion.

Security posture

The website demonstrates a moderate to good security posture. HTTPS is enforced, ensuring encrypted communications. No sensitive data leaks or vulnerable libraries were detected in the HTML content. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces the overall security hardening. There is no visible security policy or incident response contact information, which could hinder timely reporting and handling of security incidents. The use of third-party analytics scripts introduces a moderate tracking footprint but appears compliant with privacy policies. Overall, the security maturity is adequate for the platform's current scale but could be improved with additional security controls and transparency.

Recommendations

  1. Implement and publish comprehensive security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Create and make accessible a dedicated security policy and incident response page with clear contact channels for vulnerability reporting.
  3. Establish a formal vulnerability disclosure program and consider publishing a security.txt file to facilitate responsible reporting.
  4. Regularly audit and update third-party scripts and dependencies to mitigate risks from vulnerable libraries.
  5. Enhance trust by providing verified contact information and expanding transparency around data retention and privacy practices.

Technical notes

Notes

The website is built on a modern React and Next.js stack, leveraging server-side rendering and optimized asset loading for performance. It uses Google Tag Manager and Google Analytics for tracking, indicating a mature approach to user behavior analysis. The site is mobile-optimized with responsive design and good accessibility features. No CMS or hosting provider details were explicitly detected. Performance appears fast with preloading of fonts and images. The technical implementation is solid, though there is room for improvement in security header implementation and explicit hosting transparency. The site structure and metadata are well-formed, supporting SEO and social sharing through Open Graph tags.
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.
