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

6 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"

    • 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

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 company operates a SaaS business model focused on email verification services, generating revenue through tiered subscription plans and API usage. Its competitive advantage lies in high accuracy, enterprise-grade security claims, and extensive integrations with over 25 popular marketing platforms. The target market includes e-commerce, marketing agencies, technology platforms, finance, and education sectors. The partnership ecosystem includes integrations with major marketing tools and CRM platforms, enhancing its market reach. Growth indicators include a large customer base and strong brand presence. The company emphasizes customer success and free trial offerings to attract and retain users.

Security posture

QuickEmailVerification demonstrates a moderate to strong security posture with HTTPS enforced and domain transfer protections. However, the absence of DNSSEC and lack of explicit security headers such as CSP and HSTS are notable gaps. No dedicated security policy or incident response contact is published, which could hinder transparency and trust in security incident handling. The website claims encrypted storage and compliance with international regulations, but without detailed disclosures. The extensive use of third-party analytics and marketing tools increases the attack surface and privacy considerations. Overall, the security maturity is adequate but could benefit from enhanced transparency and technical controls.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, Strict-Transport-Security, and X-Content-Type-Options to harden web security.
  2. Publish a comprehensive security policy and incident response contact information to improve transparency and customer trust.
  3. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  4. Introduce a clear cookie consent mechanism to comply fully with GDPR and improve privacy compliance.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and optimize performance.

Technical notes

Notes

The website uses a modern and robust technology stack including Bootstrap 4 for responsive design, jQuery for DOM manipulation, FontAwesome for icons, and animation libraries for enhanced UX. It integrates multiple third-party services such as Calendly for scheduling, Hotjar and Microsoft Clarity for user behavior analytics, and Tawk.to for live chat support. The hosting and DNS setup is standard with no CMS detected, indicating a custom-built platform. Performance is moderate with good mobile optimization and SEO practices. Technical risks include reliance on multiple external scripts which may impact load times and privacy. There is an opportunity to improve accessibility features and implement advanced security headers to reduce technical debt and enhance resilience.
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.
