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

Capital One Arena is a prominent multi-purpose indoor arena located in Washington, D.C., serving as a venue for sports, concerts, and entertainment events. The website reflects a professional digital presence with a focus on event ticketing and venue information, targeting sports fans and event attendees. The site integrates modern web technologies including React widgets, Google Tag Manager, and OneTrust for privacy compliance, indicating a mature technical infrastructure. Security posture is strong with HTTPS enforcement and security headers, though there is room for improvement in publishing explicit security policies and incident response contacts. The absence of WHOIS registration data is a notable anomaly that warrants further investigation but does not currently detract from the site's professional appearance and trustworthiness. Overall, the site is well-structured, privacy-conscious, and serves its business purpose effectively.

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

1 finding rated critical or high. Fix these first.

  1. 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

      • 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

The arena operates under Monumental Sports & Entertainment and holds a leading position in the hospitality and entertainment sector within the Washington, D.C. market. Its business model revolves around venue management, event hosting, and partnerships with local and national brands such as DistrictE and Caesars. The website supports ticket sales and event promotion, targeting a broad audience of sports and entertainment consumers. The integration of privacy and cookie consent tools aligns with regulatory compliance and user trust. The partnership ecosystem is visible through external links, enhancing market reach and service offerings. Growth indicators include the use of advanced analytics and marketing tools, though direct revenue streams and financial data are not disclosed on the site.

Security posture

The website demonstrates a solid security foundation with HTTPS, modern security headers, and cookie consent mechanisms. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. However, the lack of a publicly accessible security policy, incident response information, and vulnerability disclosure reduces transparency and may impact user trust. The site would benefit from publishing a security.txt file and providing clear channels for reporting security incidents. Overall, the security maturity is good but could be enhanced by formalizing and communicating security governance and incident management practices.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement and expose an incident response contact or abuse reporting channel.
  3. Add a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by providing more detailed business and contact information on the website.

Technical notes

Notes

The website uses a modular hybrid JavaScript framework combined with React components for interactive widgets. It leverages Google Tag Manager and Google Analytics for tracking and marketing insights, and OneTrust for cookie consent management, reflecting compliance with privacy regulations. FontAwesome and Typekit provide consistent typography and iconography. The site is mobile-optimized and accessible, with good SEO basics implemented via meta tags and Open Graph data. Performance is moderate, with potential improvements in asset loading and caching strategies. Hosting details are not explicitly identified, but the presence of CDN-hosted scripts suggests a distributed content delivery approach. Technical risks are minimal but include reliance on multiple third-party scripts which require ongoing security monitoring.
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.
