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 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

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

VOCALLS operates in the technology sector, specifically targeting the contact center automation market with AI-powered solutions. Its business model is B2B SaaS, offering automation tools that improve agent effectiveness and customer experience. The recent acquisition by CallMiner indicates growth and strategic positioning in the AI contact center space. The company targets medium to large enterprises across multiple industries including telecommunications, financial services, and retail. The website highlights key use cases such as account management, authentication, billing, call routing, and customer service automation. The partnership ecosystem includes CallMiner and HubSpot for meetings and marketing. VOCALLS demonstrates a focus on rapid value delivery and ease of integration with existing systems, which is a competitive advantage. The absence of direct contact emails or phone numbers suggests a controlled lead generation approach via contact forms and meeting bookings.

Security posture

The website enforces HTTPS and uses advanced bot protection technologies like Google reCAPTCHA Enterprise and Cloudflare Turnstile, indicating a proactive approach to security. Cookie consent is implemented with an opt-in mechanism, supporting privacy compliance. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not clearly visible in the HTML source and should be verified or added to enhance security. No sensitive data or vulnerabilities were detected in the page content. The lack of published security policies or incident response information is a gap that could be addressed to improve transparency and readiness. WHOIS data is privacy protected, which is common and justified for this business type. Overall, the security posture is good but could be strengthened with additional headers and published policies.

Recommendations

  1. Implement and verify comprehensive security headers including CSP, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response plan on the website to enhance transparency and trust.
  3. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Consider providing direct contact information for security or abuse reporting to improve incident response readiness.
  5. Regularly audit third-party scripts and libraries to ensure no vulnerable components are included.

Technical notes

Notes

The website is built on the Webflow CMS platform, leveraging modern web technologies and integrations such as Vimeo for video content, Google Tag Manager for analytics, and Microsoft Clarity for user behavior tracking. Bot protection is robust with Google reCAPTCHA Enterprise and Cloudflare Turnstile captchas. The site is mobile optimized with responsive design and good navigation clarity. Performance is moderate, likely influenced by rich media content and third-party scripts. SEO is supported by proper meta tags and Open Graph data. Accessibility features are basic but present. Hosting appears to be via Webflow with Cloudflare services providing CDN and security layers. Technical risks are minimal, but continuous monitoring of third-party dependencies is recommended to avoid 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.
