KnowBe4 is a leading cybersecurity company specializing in human risk management and security awareness training. Their platform offers a comprehensive suite of services including phishing simulations, cloud email security, compliance training, and AI-driven defense agents. The company targets enterprises and organizations seeking to strengthen their cybersecurity posture through user education and risk mitigation. The website reflects a mature digital presence with professional design, multi-language support, and extensive resources, positioning KnowBe4 as a market leader in its domain. Technically, the website is built on the HubSpot CMS platform, leveraging modern web technologies such as jQuery, Google Fonts, and cloud-based content delivery networks. The site demonstrates good performance, mobile optimization, and accessibility features. Integration with marketing and analytics tools like HubSpot Analytics, Google Tag Manager, and Facebook Pixel indicates a sophisticated approach to user engagement and data collection. From a security perspective, the site enforces HTTPS and employs cookie consent mechanisms aligned with GDPR requirements. While explicit security headers are not fully visible in the HTML, the overall security posture is strong with no evident vulnerabilities or exposed sensitive data. However, the absence of a public security policy or vulnerability disclosure page suggests room for improvement in transparency and incident response readiness. The WHOIS data for the domain is unavailable, which is unusual for a large enterprise but may be due to privacy protections or registry policies. Despite this, the website's content, branding, and external references strongly support its legitimacy. Overall, KnowBe4's website is professional, secure, and compliant, reflecting a robust cybersecurity business with a strong market position.

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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

  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

  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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  4. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • High

      Potential Subdomain Takeover

      Subdomain staging.knowbe4.com points to unregistered service kmsat-webapp-staging-998164134.us-east-1.elb.amazonaws.com

      What to do: Remove or fix CNAME record to prevent subdomain takeover

      • WSTG-CONF-10
      • NIS2 21(2)(i)
      • IR 2024/2690 12.4: Implementing Regulation (EU) 2024/2690, Annex point 12.4: Asset inventory

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.

Its market position is strong, trusted by many top cybersecurity firms, indicating competitive advantages in content breadth and platform capabilities.

Security posture

KnowBe4 demonstrates a mature security posture with enforced HTTPS, cookie consent aligned with GDPR, and use of reputable third-party analytics and marketing services. No exposed sensitive data or vulnerable libraries were detected in the website content. However, the absence of a dedicated security policy, incident response contact, or vulnerability disclosure mechanism limits transparency and may impact incident handling effectiveness. The site could benefit from publishing explicit security headers and a security.txt file to enhance trust and readiness. Overall, the security culture appears strong, supported by the company's core business focus on cybersecurity awareness and training.

Recommendations

  1. Publish a dedicated security policy and incident response page to improve transparency.
  2. Implement and publicly document security headers such as X-Frame-Options and X-Content-Type-Options.
  3. Create and maintain a vulnerability disclosure program or security.txt file.
  4. Provide clear contact information for the Data Protection Officer or security team.
  5. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.

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.
