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

SalesViewer is a technology company specializing in B2B sales intelligence and lead generation software. Their platform identifies website visitors and provides actionable sales insights to improve sales efficiency. Positioned as a reputable player in the European market, SalesViewer targets sales and marketing professionals seeking to enhance their lead generation and CRM integration capabilities. The website demonstrates a high level of professionalism with excellent content quality, clear navigation, and mobile optimization. Technically, the site is built on WordPress with modern SEO and accessibility practices, ensuring good performance and user experience. Security posture is solid with HTTPS enforcement and security headers, though the absence of a public security policy and incident response details suggests room for improvement. The lack of WHOIS registration data is a concern for domain legitimacy, but the overall business presence and trust indicators support a positive credibility assessment. Strategic recommendations include publishing security policies, adding vulnerability disclosure mechanisms, and verifying domain registration details to enhance trust and compliance.

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 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 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

      SSL Certificate Expires Soon

      SSL certificate expires in 29 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

SalesViewer operates a SaaS business model focused on providing sales intelligence tools to B2B companies. Their competitive advantage lies in real-time website visitor identification and seamless CRM integration. The company leverages digital marketing and SEO to attract mid-sized enterprises and sales teams. Their partnership ecosystem includes integrations with popular CRM platforms and marketing tools. Growth indicators include active customer testimonials, Google reviews, and press mentions. The company maintains consistent branding and professional content, reinforcing market trust. Revenue streams are primarily subscription-based, targeting sales and marketing departments across various industries. The business intelligence suggests a mature operation with a focus on technology-driven sales enablement.

Security posture

The website enforces HTTPS and implements key security headers, reflecting a good security baseline. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of a dedicated security policy page and incident response contact channels indicates a gap in transparency and preparedness. GDPR compliance is evident through privacy and cookie policies with consent mechanisms. The security posture is adequate for a SaaS provider but could be enhanced by formalizing vulnerability disclosure and incident response processes. Overall, the security maturity is moderate with opportunities to strengthen trust and compliance.

Recommendations

  1. Publish a comprehensive security policy and incident response plan on the website.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Verify and publicly confirm domain registration details to improve legitimacy and trust.
  4. Regularly audit and update third-party scripts and libraries to mitigate potential vulnerabilities.
  5. Enhance transparency around data retention policies and user privacy controls.

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.
