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

QuickEmailVerification is a well-established technology company specializing in email verification and list cleaning services. Founded in 2014, it serves a broad audience including email marketers and developers by providing bulk email verification and real-time API solutions. The company is trusted by over 191,000 businesses, including major enterprises such as IBM, Amazon, and Salesforce, positioning it as a leading player in the email validation market. Their business model is SaaS-based with tiered pricing and free trial credits to attract new users. Technically, the website employs a modern technology stack including Bootstrap, jQuery, FontAwesome, and integrates multiple third-party analytics and marketing tools such as Google Analytics, Hotjar, Microsoft Clarity, and Calendly. The site is mobile-optimized, well-structured, and demonstrates good SEO practices. Hosting and DNS are managed through reputable providers, though DNSSEC is not enabled, which is a minor security gap. From a security perspective, the site enforces HTTPS and uses clientTransferProhibited status on the domain to prevent unauthorized transfers. While no explicit security policy or incident response contacts are published, the site claims encrypted storage and compliance with GDPR. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is generally good, though the absence of a cookie consent mechanism is noted. Overall, the website is professional, trustworthy, and secure with minor areas for improvement in privacy compliance and DNS security. The domain registration data aligns well with the business claims, supporting legitimacy. Strategic recommendations include enabling DNSSEC, publishing a security.txt file, and implementing cookie consent to enhance compliance and trust.

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

QuickEmailVerification operates in the technology sector, focusing on email verification services that improve email deliverability and reduce bounce rates. Its competitive advantage lies in high accuracy, extensive integrations with over 25 popular marketing tools, and a large customer base including Fortune 50 companies. The SaaS business model with free tier credits encourages adoption and retention. The company targets email marketers, developers, and enterprises needing reliable email validation. Growth indicators include a large verified email volume (30 billion emails verified) and a 4.8/5 user rating. The partnership ecosystem includes integrations with major marketing platforms and CRM tools, enhancing market reach and product stickiness. The company maintains a strong brand presence with consistent messaging and trust signals.

Security posture

The security posture of QuickEmailVerification is solid with HTTPS enforced and domain transfer protections in place. The company claims encrypted storage and GDPR compliance, indicating attention to data protection. However, the absence of DNSSEC and a published security policy or incident response contacts are gaps that could be addressed to improve transparency and resilience. The use of multiple third-party scripts and analytics tools introduces some risk, but no vulnerable libraries or exposed sensitive data were found. The site lacks a cookie consent mechanism, which is a compliance risk under privacy regulations. Overall, the security maturity is good but could benefit from formalized policies and enhanced DNS security.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file and explicit security policy including incident response contacts.
  3. Implement a cookie consent mechanism to comply with GDPR and other privacy laws.
  4. Regularly audit and update third-party scripts to mitigate potential vulnerabilities.
  5. Enhance transparency by providing more detailed data protection and privacy documentation.

Notes

The website is built on a modern and robust technology stack including Bootstrap 4, jQuery, and FontAwesome, ensuring responsive design and good user experience. Integration of advanced analytics and marketing tools like Hotjar, Microsoft Clarity, and Google Tag Manager indicates a mature digital marketing approach. Performance is moderate with asynchronous loading of scripts and optimized assets. The site is mobile-friendly and SEO optimized with proper meta tags and structured navigation. Hosting and DNS are stable, though DNSSEC is not enabled. No CMS was detected, suggesting a custom or proprietary platform. Technical risks are minimal but include reliance on multiple third-party scripts which require ongoing security management.
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.
