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

VIRTUAL ZOOM s.r.o. operates a professional website focused on providing automated email marketing and CRM solutions tailored for the hospitality industry, including hotels and restaurants. Their flagship product, ZOOM LETTER, offers automated and one-time email campaigns, client database management, and integrations with PMS and payment systems. The company positions itself as a reliable partner with a strong regional presence and a portfolio of satisfied clients, supported by detailed testimonials and a comprehensive service offering. Technically, the website employs modern JavaScript libraries such as jQuery, AOS, and Google Tag Manager, alongside Google reCAPTCHA v3 for form security and a proprietary cookie management system. The site is well-optimized for mobile devices and demonstrates good SEO practices. Security posture is solid with HTTPS enforced and consent-based tracking, though some security headers and explicit policies are missing. The WHOIS data for the domain www.virtualzoom.com is unavailable, indicating either a recent registration, privacy protection, or a potential issue with domain legitimacy. Despite this, the website content and business information appear professional and trustworthy. No signs of malicious or adult content were detected, and the site complies with GDPR requirements through clear privacy and cookie policies. Overall, VIRTUAL ZOOM presents a credible digital marketing service for the hospitality sector with a mature technical infrastructure and good privacy practices. However, the absence of WHOIS data and some security policy disclosures suggest areas for improvement in transparency and security documentation.

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

7 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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 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

      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

      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

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

VIRTUAL ZOOM targets the hospitality sector with specialized digital marketing tools, focusing on email automation, loyalty programs, and e-commerce for gift vouchers. Their business model is B2B SaaS combined with digital services, catering to hotels and restaurants primarily in the Czech Republic. The company leverages integrations with PMS and payment gateways to streamline client communications and sales processes. Testimonials from reputable clients indicate strong market positioning and customer satisfaction. The company maintains active social media channels and provides multiple contact points, enhancing customer engagement and support. Growth potential lies in expanding integrations and enhancing automation capabilities.

Security posture

The website demonstrates a moderate to strong security posture with HTTPS enforced and use of Google reCAPTCHA v3 to protect forms from abuse. Cookie consent mechanisms comply with GDPR, providing users control over tracking preferences. However, the absence of key security headers such as Content-Security-Policy and lack of published security policies or incident response plans represent gaps in security maturity. No vulnerabilities or exposed sensitive data were detected in the HTML content. The missing WHOIS data raises concerns about domain registration transparency, which should be addressed to improve trustworthiness. Overall, the security culture appears adequate but could benefit from enhanced documentation and technical controls.

Recommendations

  1. Implement and publish a security.txt file to facilitate vulnerability reporting and improve transparency.
  2. Add essential security headers like Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to harden the website against common attacks.
  3. Publish a dedicated security policy and incident response page to inform users and partners about security practices and contact points.
  4. Verify and update WHOIS domain registration information to ensure transparency and domain legitimacy.
  5. Conduct regular audits of third-party scripts and dependencies to mitigate risks from vulnerable libraries.

Technical notes

Notes

The website uses a modern and well-maintained technology stack including jQuery, AOS for animations, Slick Carousel for sliders, and Google Tag Manager for analytics and marketing tags. The integration of Google reCAPTCHA v3 enhances form security. The site is mobile responsive and optimized for SEO with proper meta tags and Open Graph data. However, no CMS was explicitly detected, suggesting a custom or proprietary platform. Performance is moderate with asynchronous loading of scripts. The cookie management system is custom-built, indicating investment in privacy compliance. Hosting provider details are not disclosed. Opportunities exist to improve accessibility features and implement additional security headers 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.
