Risk levelMedium

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

Blockchain Capital is a venture capital firm specializing in investments in blockchain and cryptocurrency startups since 2013. The company positions itself as a partner to crypto builders, offering venture funding, portfolio management, and research services. The website reflects a professional and consistent brand image targeting investors and blockchain entrepreneurs. The technical infrastructure is built on Webflow CMS with modern JavaScript libraries and CDN hosting, providing a moderate to good performance and mobile optimization. Security posture is solid with HTTPS enabled and no obvious vulnerabilities, though the absence of security headers and explicit security policies suggests room for improvement. Privacy compliance is partial, with a privacy policy present but lacking a cookie consent mechanism. The missing WHOIS data for the domain raises concerns about domain registration legitimacy, which should be verified to ensure trustworthiness. Overall, the website is professional and trustworthy but could enhance security and compliance transparency.

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

4 findings rated critical or high. Fix these first.

  1. 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

  2. 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

Blockchain Capital operates in the finance and technology sectors, focusing on venture capital investments in the blockchain ecosystem. Their business model revolves around funding early to growth-stage crypto startups and managing a portfolio of high-profile blockchain companies. The firm maintains a strong market position with a history dating back to 2013 and a visible presence through blogs, fund reviews, and social media channels. The company leverages partnerships and dedicated portals for investors and job seekers, indicating a mature operational structure. Revenue streams likely include management fees and carried interest from investment funds. The target customer segments include crypto entrepreneurs, institutional investors, and blockchain developers. Strategic observations highlight the firm's emphasis on transparency and thought leadership, though domain registration inconsistencies warrant attention.

Security posture

The website demonstrates a good security maturity level with HTTPS enforced and no exposed sensitive data in the HTML content. However, the lack of common security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the overall security robustness. There is no published security policy or incident response information, which limits transparency and preparedness perception. No vulnerability disclosure or security.txt file is present, which could hinder responsible vulnerability reporting. The absence of a cookie consent mechanism despite cookie usage may pose compliance risks under GDPR and similar regulations. Overall, the security posture is adequate for a financial services website but could be significantly improved by adopting best practices and enhancing compliance documentation.

Recommendations

  1. Implement standard security headers (CSP, X-Frame-Options, X-Content-Type-Options) to enhance protection against common web attacks.
  2. Add a clear cookie consent banner and mechanism to comply with GDPR and other privacy regulations.
  3. Publish a detailed security policy and incident response plan accessible to users and partners.
  4. Create and maintain a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Verify and update domain WHOIS registration information to ensure transparency and trustworthiness.

Technical notes

Notes

The website is built using Webflow CMS with jQuery and custom JavaScript for interactivity. It uses CDN hosting for static assets, which supports moderate performance and good availability. The site is mobile optimized with responsive design and includes SEO-friendly meta tags and Open Graph data. Accessibility features are basic but present. There is no evidence of outdated or vulnerable libraries. The site lacks some advanced security headers and cookie consent mechanisms, which are technical gaps. The absence of WHOIS data suggests a need for domain registration verification. Overall, the technical infrastructure is modern and functional but can benefit from enhanced security and compliance 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.
