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

AngelList is a prominent platform specializing in private fund management and venture capital services. It offers a comprehensive suite of tools for investors and innovators to raise capital, manage portfolios, and streamline fund administration. The platform targets venture funds, SPVs, scout funds, and digital subscription workflows, positioning itself as a leader in the private finance technology sector. The website reflects a mature digital presence with professional design and clear navigation, catering to a sophisticated audience of investors and fund managers. Technically, AngelList employs a modern technology stack including React and Next.js, supported by marketing and analytics integrations such as Marketo, Segment, and Clearbit. The site is optimized for performance and mobile responsiveness, with good accessibility and SEO practices. Security is robust with HTTPS enforced and multiple security headers implemented, alongside a cookie consent mechanism ensuring privacy compliance. While the website demonstrates strong security posture and privacy compliance, it lacks explicit published security policies, incident response procedures, and vulnerability disclosure information, which are recommended for enhanced transparency and trust. The WHOIS data is incomplete or unavailable, which slightly impacts trustworthiness but does not detract significantly given the overall professional presentation and business legitimacy. Overall, AngelList presents a secure, compliant, and user-friendly platform with a strong market position in the finance and technology sectors. Strategic improvements in security transparency and WHOIS data availability would further strengthen its credibility and trust.

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

3 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. 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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

AngelList operates in the finance and technology sectors, focusing on private fund administration and venture capital facilitation. Its business model revolves around providing SaaS solutions to investors and fund managers, enabling capital raising, deal closing, and portfolio management. The platform's competitive advantage lies in its integrated approach to fund management and its extensive network of investors and innovators. Revenue streams likely include subscription fees, transaction fees, and premium services. The target customer segments include venture funds, startups, and individual investors. Partnerships with industry leaders enhance its ecosystem and market reach. The company's operations reflect a mature and scalable business with strong growth potential in the private finance technology market.

Security posture

AngelList demonstrates a strong security posture with HTTPS enforced and comprehensive security headers such as Content Security Policy, Strict-Transport-Security, and X-Frame-Options. The presence of a cookie consent mechanism indicates attention to privacy compliance. However, the absence of publicly available security policies, incident response plans, and vulnerability disclosure mechanisms suggests room for improvement in transparency and readiness. No vulnerabilities or exposed sensitive data were detected in the analysis. The integration of reputable marketing and analytics tools is managed with consent controls, reducing privacy risks. Overall, the security maturity is good but could be enhanced by publishing formal security documentation and contact channels for security incidents.

Recommendations

  1. Publish a detailed security policy and incident response plan on the website to improve transparency and user trust.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  3. Provide clear contact information for a Data Protection Officer or security team to facilitate communication regarding data protection and security incidents.
  4. Regularly review and update third-party integrations to ensure no vulnerable libraries or privacy risks are introduced.
  5. Enhance WHOIS data accuracy and transparency to strengthen domain registration trustworthiness.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring a performant and responsive user experience. Integration with marketing and analytics platforms such as Marketo, Segment, and Clearbit supports data-driven business operations. The site employs best practices in SEO, accessibility, and mobile optimization. No CMS was explicitly detected, suggesting a custom or headless architecture. Hosting details are not explicitly available but the site loads quickly and securely over HTTPS. The technical infrastructure supports scalability and robust user engagement, though continuous monitoring of third-party scripts and dependencies is advised to mitigate potential 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.
