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

The website www.angelthebook.com serves as a promotional platform for Jason Calacanis's book 'Angel', which provides advice on angel investing. The site targets angel investors and entrepreneurs interested in startup investing, offering educational content, event information, and links to purchase the book. Technically, the site is built on Webflow, leveraging modern web technologies and third-party analytics and advertising tools. The site is mobile-optimized and well-structured, though it lacks some accessibility features and security headers. Security posture is moderate with HTTPS enabled but missing key headers and privacy policies. The absence of WHOIS registration data raises concerns about domain legitimacy, although the professional content and external references mitigate some risk. Overall, the site is functional and professional but would benefit from improved privacy compliance and security hardening.

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 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 business model centers on book sales, podcast promotion, and event marketing within the technology and angel investing niche. The site leverages partnerships with major book retailers and publishers, indicating a credible market position. The target audience includes angel investors and startup founders seeking investment insights. The presence of testimonials and publisher logos enhances trust. However, the lack of direct company contact emails and missing WHOIS data suggest gaps in transparency. The extensive use of tracking and advertising tools indicates a focus on marketing and audience engagement. Growth potential is tied to the popularity of the author and the angel investing market segment.

Security posture

The website employs HTTPS and uses secure form inputs, which are positive security indicators. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces protection against common web attacks. No explicit security or incident response policies are published, and privacy compliance is weak due to missing privacy and cookie policies. The use of multiple third-party tracking scripts increases the attack surface and privacy risks. No vulnerabilities or exposed sensitive data were detected in the content. Overall, the security posture is moderate but requires improvements to meet best practices and regulatory compliance.

Recommendations

  1. Implement comprehensive privacy and cookie policies with clear GDPR compliance statements.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection.
  3. Publish explicit security and incident response policies to improve transparency and readiness.
  4. Review and limit third-party tracking scripts to reduce privacy risks and improve performance.
  5. Investigate and resolve WHOIS data absence to improve domain legitimacy and trust.

Technical notes

Notes

The website is built on the Webflow platform, utilizing modern front-end technologies including jQuery and Google Web Fonts. It integrates multiple analytics and marketing tools such as Google Analytics, Facebook Pixel, Twitter Pixel, and AdRoll for retargeting. The site is mobile-optimized with responsive design and good SEO meta tags. Performance is moderate, with asynchronous loading of scripts to improve speed. However, accessibility features are basic and could be enhanced. The lack of security headers and privacy mechanisms indicates technical debt in security and compliance areas. Hosting is managed by Webflow, which provides reliable infrastructure but requires proper configuration for security best practices.
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.
