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

Arche Capital is an early-stage venture capital firm specializing in investments at the intersection of financial services, blockchain technology, and artificial intelligence. The firm positions itself as a thesis-driven, long-term investor focusing on the emerging Web3 ecosystem and the transformation of global finance through permissionless, open financial infrastructure. Their website highlights a portfolio of companies across infrastructure, zero-knowledge proofs, fintech, decentralized AI, and liquid markets, supported by a team with strong backgrounds in finance, technology, and venture capital. Technically, the website is built using modern web technologies, likely React, and hosted on a performant platform such as Vercel. The site is mobile optimized, well-structured, and provides a professional user experience with clear navigation and relevant content. However, there is a lack of explicit privacy, cookie, and terms of service policies, which are important for compliance and user trust. From a security perspective, the site uses HTTPS but lacks visible security headers and formal security policies or incident response contacts. No vulnerabilities or exposed sensitive data were detected in the provided content. The WHOIS data is privacy protected, which is common for VC firms, but limits transparency about domain ownership. Overall, the security posture is moderate but could be improved with better policy disclosures and security headers. The overall risk assessment is low to moderate. The firm appears legitimate and professional, but improvements in privacy compliance, security transparency, and contact information would enhance trust and reduce potential risks. Strategic recommendations include publishing comprehensive privacy and cookie policies, implementing security headers, providing clear contact channels for security incidents, and enhancing accessibility features.

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 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';…

  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

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

Arche Capital operates in the competitive venture capital market focusing on Web3, blockchain, AI, and fintech sectors. Their business model centers on early-stage investments in startups and protocols that align with their thesis on the future of global finance. The firm leverages the expertise of its managing partners, who have strong industry backgrounds and networks, to identify promising opportunities. The portfolio is diversified across multiple sub-sectors within the blockchain and AI space, indicating a broad investment strategy. The lack of public company registration details and limited contact information suggests a lean operational structure typical of boutique VC firms. The firm’s market positioning as a long-term, thesis-driven investor differentiates it from opportunistic or short-term focused funds. Growth indicators include a well-curated portfolio and experienced team, but public-facing transparency could be improved to attract broader investor confidence.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enabled, ensuring encrypted communications. However, the absence of key security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces protection against common web attacks. No explicit privacy or cookie policies are published, which is a compliance gap under GDPR and similar regulations. The lack of incident response or abuse contact information limits the firm's readiness to handle security incidents transparently. No vulnerable libraries or exposed sensitive data were detected in the HTML content. The security culture appears nascent, with room for improvement in policy transparency and technical hardening. Implementing a security.txt file and vulnerability disclosure program would enhance trust and preparedness.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Implement and configure essential security headers such as CSP, HSTS, and X-Frame-Options.
  3. Provide clear contact information including security and abuse email addresses for incident response.
  4. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  5. Enhance website accessibility features to improve inclusivity and compliance with standards.

Technical notes

Notes

The website is built with modern front-end technologies, likely React, and uses a modular JavaScript approach. Hosting appears to be on Vercel, providing fast and reliable delivery. The site is mobile responsive and well-structured with semantic HTML elements. Performance is likely fast given the minimal external dependencies and optimized assets. However, there is no evidence of a CMS or backend platform from the HTML content. The site lacks advanced SEO structured data such as JSON-LD, which could improve search visibility. No analytics or tracking scripts were detected, indicating minimal data collection. Technical debt appears low, but opportunities exist to improve SEO, accessibility, and security configurations to reduce operational risks.
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.
