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

3 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 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 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

      SSL Certificate Expires Soon

      SSL certificate expires in 18 days

      What to do: Renew SSL certificate before expiration

      • NIS2 21(2)(h)
      • IR 2024/2690 9.2(c): Implementing Regulation (EU) 2024/2690, Annex point 9.2(c): Cryptography
      • NIST SC-17: NIST SP 800-53 Rev. 5 SC-17: Public Key Infrastructure Certificates

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

Five9 operates in the technology sector as a SaaS provider specializing in cloud contact center software and AI services. Their business model focuses on subscription-based software delivery to enterprises. The company benefits from a strong brand, extensive customer base, and positive user reviews. Their target customers are businesses requiring advanced customer engagement solutions. The website's integration with multiple analytics and marketing tools suggests a data-driven approach to customer acquisition and retention. While no parent company or subsidiaries were identified, Five9 maintains active social media channels and a clear contact infrastructure. The lack of publicly available WHOIS data is a minor concern but does not detract significantly from their market credibility.

Security posture

The website enforces HTTPS and uses reputable third-party analytics and optimization services, which is positive for security. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options were not detected in the HTML content, representing an area for improvement. No vulnerabilities or exposed sensitive data were found in the analysis. The absence of a public security policy or incident response contact reduces transparency in security governance. Overall, the security posture is good but could be enhanced by implementing recommended headers and publishing security policies to build greater trust.

Recommendations

  1. Implement explicit Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options headers to strengthen security.
  2. Publish a clear security policy and incident response contact information on the website.
  3. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  4. Improve WHOIS data availability or transparency to enhance domain trustworthiness.
  5. Maintain and enhance privacy compliance measures, including clear data retention policies.

The technical infrastructure supports good mobile optimization and accessibility. Performance is moderate, with room for improvement in load times and resource optimization.

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.
