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

TwentyThree is a European leader in video software, offering a comprehensive SaaS platform that enables businesses to leverage video marketing, webinars, and personal video tools. The company positions itself as the first platform to provide all necessary video tools for every customer touchpoint, targeting medium-sized businesses and enterprises. Their website is professionally designed, mobile-optimized, and SEO-friendly, reflecting a mature digital presence. Technically, the site uses modern frameworks such as Tailwind CSS and Alpine.js, integrates Google Tag Manager for analytics, and is hosted on a reliable CDN infrastructure, likely AWS Cloudfront. Security-wise, the site enforces HTTPS and implements cookie consent mechanisms, but lacks explicit security policies and incident response information, which could be improved. The absence of WHOIS data for the domain raises some concerns about registration legitimacy, although the website content and branding appear consistent and trustworthy. Overall, the site demonstrates a solid business and technical foundation with room for enhanced transparency and security disclosures.

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"

    • 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. 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
    • High

      SSL Certificate Expires Soon

      SSL certificate expires in 22 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

TwentyThree operates in the technology sector, focusing on video marketing and webinar solutions delivered via a SaaS model. Their market positioning as a leading European player with a global reach suggests competitive advantages in comprehensive video tools and user engagement. The business model relies on subscription-based revenue streams targeting marketing teams and enterprises seeking to upgrade their video capabilities. The presence of customer cases, reports, and a partner directory indicates a well-established partnership ecosystem and customer base. Growth indicators include active content marketing and webinar offerings. However, the lack of visible direct contact information and WHOIS transparency may impact trust for some prospects.

Security posture

The website exhibits a moderate to good security posture with HTTPS enforced and cookie consent implemented, aligning with GDPR requirements. However, the absence of explicit security policies, incident response contacts, and vulnerability disclosure mechanisms limits transparency and preparedness perception. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. The use of third-party scripts like Google Tag Manager and HubSpot forms necessitates ongoing security audits to mitigate supply chain risks. Publishing a security.txt file and clear incident response procedures would enhance security maturity and stakeholder confidence.

Recommendations

  1. Publish a dedicated security policy and incident response information on the website.
  2. Add a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  3. Include clear and verified contact information for business and security inquiries.
  4. Implement and explicitly declare comprehensive security headers such as X-Frame-Options and X-Content-Type-Options.
  5. Verify and update WHOIS domain registration details to improve legitimacy and trust.

Technical notes

Notes

The website leverages a modern technology stack including Tailwind CSS for styling and Alpine.js for interactivity, hosted on a performant CDN likely AWS Cloudfront. Google Tag Manager is used for analytics and tracking, integrated with HubSpot forms for lead capture and cookie consent management. The site is mobile-optimized with responsive design and good accessibility features. SEO is well addressed with proper meta tags and Open Graph data. No broken elements or errors were detected in the HTML content. Opportunities exist to enhance security headers and publish more detailed security and privacy documentation to reduce technical risks.
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.
