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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  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';…

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

SevenVentures targets high-growth consumer digital companies, offering flexible investment models including Media-for-Equity and Media-for-Revenue. Their portfolio includes notable companies like Ottonova, Sanity Group, FRIDAY, Refurbed, and Grover, indicating a focus on innovative digital health, insurance, sustainability, and technology rental sectors. The company benefits from the backing of ProSiebenSat.1, providing strong market positioning and access to premium media channels. Their business model combines media investment with strategic minority and majority stakes, supporting brand development and market expansion. The partnership ecosystem is robust, with clear links to portfolio companies and accelerator programs, reflecting a comprehensive growth strategy.

Security posture

The website employs modern SSL/TLS protocols (TLS 1.3 and 1.2) with no known vulnerabilities such as Heartbleed or FREAK. SPF records are correctly configured to prevent email spoofing. However, the absence of DNSSEC, CAA records, HSTS, OCSP stapling, and DMARC indicates gaps in DNS and transport security best practices. No explicit security or incident response policies are found on the site, and no dedicated security contact emails are provided. The security score is moderate, reflecting a good baseline with room for enhancement to meet advanced security standards and compliance requirements such as GDPR and NIS2.

Recommendations

  1. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload to enforce HTTPS and prevent downgrade attacks.
  2. Implement DNSSEC to protect against DNS spoofing and cache poisoning attacks.
  3. Add a DMARC record to improve email authentication and reduce phishing risks.
  4. Enable OCSP stapling to improve SSL certificate revocation checking performance and security.
  5. Publish a security.txt file and vulnerability disclosure policy to facilitate responsible security reporting.
Technical notes

Notes

The website is built on Next.js, a React framework, indicating a modern and scalable front-end architecture. It uses a proprietary CMS and media management system (Seven.One MIM) for content delivery. Hosting appears to be on AWS infrastructure. Performance metrics show moderate load times with a page size of approximately 120KB and 87 resources loaded. Mobile optimization is good with responsive design elements. SEO is well addressed with meta tags, Open Graph images, and structured data for portfolio and team details. The site integrates Google Tag Manager and a third-party tracking extension for marketing analytics. Technical risks include lack of advanced DNS security features and partial absence of security headers.
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.
