Risk levelMedium

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

MASTERKEY VC is a blockchain and crypto-focused early-stage venture capital fund based in Israel, investing across the crypto industry including mining, energy technologies, and Layer 1 protocols. The website presents a professional but basic digital presence built on the Wix platform, with essential branding and social media integration. Technical infrastructure relies on Wix's Thunderbolt platform with standard JavaScript libraries and Sentry for error monitoring. Security posture is adequate with HTTPS and cookie management but lacks explicit security policies or vulnerability disclosure mechanisms. Privacy compliance is limited, with no privacy policy or terms of service found, though a cookie consent banner is present. Overall, the site is functional and moderately trustworthy but would benefit from enhanced privacy and security 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

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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

The company positions itself as a leading early-stage blockchain VC in Israel, targeting crypto startups and entrepreneurs. Its business model centers on venture capital funding and startup incubation within the crypto ecosystem. The website content emphasizes support for foundational blockchain technologies and crypto expansion. Social media presence on Twitter and LinkedIn supports outreach and credibility. No physical address or phone contact is provided, which is common for VC firms. The lack of detailed corporate information and policies suggests a small-sized operation focused on niche technology investments.

Security posture

The website enforces HTTPS and uses cookie handling scripts to protect session cookies. Sentry integration indicates proactive error monitoring. However, there is no explicit Content-Security-Policy header detected, no published security or incident response policies, and no vulnerability disclosure or security.txt file. These gaps reduce transparency and may impact trust for security-conscious visitors. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall security maturity is moderate but could be improved with published policies and stronger headers.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service to improve privacy compliance and user trust.
  2. Implement and publish a security policy and incident response contact information to enhance security transparency.
  3. Add a security.txt file to facilitate vulnerability disclosure and responsible reporting.
  4. Enhance HTTP security headers, including Content-Security-Policy and X-Frame-Options.
  5. Improve mobile optimization and accessibility features to enhance user experience.

Technical notes

Notes

The website is built on the Wix platform using Wix Thunderbolt and Wix UI libraries, with JavaScript polyfills and Sentry for error monitoring. Hosting is provided by Wix with data centers in Ireland. Performance is moderate with video background and standard CSS/JS bundles. The site is not fully responsive but has basic mobile optimization. SEO metadata is present but limited. No advanced analytics or tracking services detected beyond Sentry. The technical stack is modern but constrained by Wix platform capabilities, with opportunities for improved performance and accessibility.
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.
