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

LongeVC is a specialized venture capital firm focused on investing in early-stage biotech companies that aim to create an ageless future. Their mission centers on supporting visionary biotech founders and bringing breakthrough science to market that can transform health outcomes. The website reflects a professional and consistent brand image, targeting biotech founders, investors, and longevity industry stakeholders. Technically, the site is built on the Tilda platform, leveraging modern web technologies and integrating Google Tag Manager for analytics. The site is mobile optimized and provides a good user experience with clear navigation and relevant content. Security posture is adequate with HTTPS enabled and no exposed sensitive data, but lacks advanced security headers and DNSSEC. Privacy compliance is weak due to absence of privacy and cookie policies. Overall, the domain registration is consistent with the business history and no suspicious patterns are detected, supporting a high legitimacy score.

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

7 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 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 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 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

    • 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

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.

Dark web exposure

Add-on

Leaked records that mention longevc.com, from OffSeq Breach.

No leaked records found

Breach holds no records for longevc.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

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

Business context

Business profile

LongeVC positions itself as a niche venture capital firm in the healthcare and biotech sectors, focusing on longevity and molecular aging mechanisms. Their business model revolves around early-stage investments and ecosystem building, connecting founders with thought leaders globally. The website content and recent insights indicate active engagement in the biotech investment community. The firm appears small but specialized, with a clear market position and professional digital presence. The lack of detailed contact information and compliance documentation suggests room for maturity in corporate governance and regulatory adherence.

Security posture

The website demonstrates a baseline security posture with HTTPS enforced and no visible sensitive data leaks. However, the absence of DNSSEC and security headers such as Content-Security-Policy and X-Frame-Options reduces the overall security robustness. No incident response or security policy information is published, which could hinder transparency and trust. The use of third-party scripts like Google Tag Manager requires ongoing monitoring to mitigate supply chain risks. Privacy compliance gaps, including missing privacy and cookie policies, expose the firm to regulatory risks under GDPR and similar frameworks.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Enable DNSSEC on the domain to enhance DNS security.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to the web server configuration.
  4. Publish a security policy and incident response contact information to improve transparency and trust.
  5. Regularly audit third-party scripts and dependencies for vulnerabilities and update them accordingly.

Technical notes

Notes

The website is built using the Tilda website builder platform, utilizing HTML5, CSS3, JavaScript, and jQuery. It integrates YouTube iframe API for video content and Google Tag Manager for analytics and tracking. The site is hosted with resources served from Tilda's CDN and uses GoDaddy as the domain registrar. Performance is moderate with good mobile optimization and basic accessibility features. SEO optimization is basic with proper meta tags and Open Graph tags present. The technical stack is modern but could benefit from enhanced security configurations and performance tuning.
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.
