NIS2 Art. 21(2)

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

4 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

  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.

Technical appendix

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

Business context

Business profile

Accel operates in the technology sector as a venture capital firm, focusing on early to growth-stage startups. Its business model revolves around investment and portfolio management, leveraging a strong reputation and market presence. The company targets innovative startups and entrepreneurs globally, supported by multiple office locations in the US, UK, and India. The website's content and structure support lead generation and investor relations, with a clear emphasis on transparency and engagement. The firm uses advanced marketing and analytics tools to monitor user engagement and optimize outreach. No direct parent or subsidiary relationships are evident from the website content.

Security posture

The website employs HTTPS with an excellent SSL configuration, ensuring secure data transmission. It uses multiple analytics and tracking services with user consent mechanisms, reflecting GDPR compliance. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure pages indicates room for improvement in transparency and readiness. No security headers were detected in the HTML content, which could enhance protection against common web attacks. No vulnerabilities or exposed sensitive data were found in the source. Overall, the security posture is good but could be strengthened by publishing formal security documentation and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a dedicated security policy and incident response page to improve transparency and readiness.
  2. Add HTTP security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Create and maintain a vulnerability disclosure or security.txt file to encourage responsible reporting of security issues.
  4. Include contact information for a Data Protection Officer or security team to comply with privacy regulations and improve trust.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and ensure compliance with evolving regulations.

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.
