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

Arcium is a technology company specializing in decentralized confidential computing, enabling encrypted computations over encrypted data. Positioned as an innovative player in the encrypted supercomputer and blockchain privacy space, Arcium targets developers, organizations, and individuals seeking enhanced data privacy and security. The company offers key services including AI model training on encrypted data, blockchain confidentiality layers, and support for decentralized physical infrastructure networks (DePIN). The website reflects a modern, professional digital presence with strong branding and investor backing, indicating a credible market position. Technically, the website is built on Webflow with modern JavaScript frameworks and integrates privacy-focused analytics tools such as Fathom and Markfi. It demonstrates good performance, mobile optimization, and accessibility. However, privacy compliance is basic, lacking explicit cookie consent mechanisms and detailed GDPR indicators. Security posture is solid with HTTPS and security headers but lacks published security policies or incident response information. Overall, Arcium's digital maturity is strong for a technology startup, with room for improvement in privacy compliance and security transparency. The absence of direct contact emails or phone numbers limits immediate user engagement channels. No critical vulnerabilities or suspicious content were detected, supporting a high trustworthiness rating. Strategic recommendations include enhancing privacy and cookie consent mechanisms, publishing comprehensive security and incident response policies, and providing clear contact channels for security and abuse reporting to strengthen user trust and compliance posture.

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.

Business context

Business profile

Arcium operates in the emerging market of decentralized confidential computing, leveraging cryptography to enable encrypted data processing without exposing underlying data. Its business model centers on providing a decentralized encrypted supercomputer platform that supports AI, blockchain, and physical infrastructure networks. The company benefits from notable investors such as Coinbase Ventures and Jump, enhancing its credibility and growth potential. Target customers include blockchain developers, AI researchers, and organizations requiring data privacy. The website's content and investor logos suggest a focus on innovation and privacy-centric technology solutions. Partnerships with community platforms like Discord and presence on GitHub indicate active developer engagement. Revenue streams likely include platform usage fees and enterprise solutions. The company is positioned as a niche technology innovator with a small but growing footprint.

Security posture

The website enforces HTTPS with strong SSL configuration and implements key security headers such as Content-Security-Policy and Strict-Transport-Security, reflecting good baseline security practices. No exposed sensitive data or vulnerable libraries were identified in the HTML content. Forms are secured with required fields but lack explicit anti-CSRF tokens or CAPTCHA mechanisms. The absence of published security policies, incident response plans, or vulnerability disclosure programs represents a compliance gap. No contact emails for security or abuse reporting were found, limiting incident response readiness. Privacy policy exists but is basic, and cookie consent mechanisms are missing, which may impact GDPR compliance. Overall, the security posture is good but could be enhanced by transparency and formalized policies.

Recommendations

  1. Implement a clear cookie consent banner and detailed cookie policy to improve privacy compliance.
  2. Publish a comprehensive security policy and incident response plan accessible on the website.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Provide dedicated security and abuse contact emails to facilitate incident communication.
  5. Enhance form security with anti-CSRF tokens and CAPTCHA to prevent automated abuse.

Hosting is via Webflow's CDN, ensuring fast load times and global availability. The site is mobile-optimized with smooth scrolling and accessibility features such as focus outlines and semantic HTML. Meta tags and structured data (JSON-LD) are well implemented for SEO and social sharing. No legacy or vulnerable libraries were detected. The technical infrastructure is modern and well-maintained, supporting a positive user experience and reliable performance. Opportunities exist to improve technical security controls on forms and enhance privacy 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.
