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 detailed company data to help sales teams increase conversion rates and optimize outreach. The company targets B2B sales and marketing professionals primarily in Europe, offering a SaaS subscription model. The website is professionally designed, mobile-optimized, and SEO-friendly, reflecting a mature digital presence. Technical infrastructure is based on WordPress CMS with modern frameworks and security best practices, including HTTPS and security headers. However, WHOIS data is unavailable, which raises some concerns about domain registration transparency. Privacy and cookie policies are comprehensive and GDPR compliant, but no explicit security policy or incident response information is published. Overall, the site demonstrates a strong security posture with room for improvement in transparency and vulnerability disclosure. Strategic recommendations include publishing a security policy, adding incident response contacts, and implementing a vulnerability disclosure program 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

2 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

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 holds a solid position in the sales intelligence market, leveraging technology to provide actionable insights for B2B sales teams. Their competitive advantage lies in real-time visitor identification and CRM integration capabilities. The business model is subscription-based SaaS, targeting medium-sized enterprises and sales professionals. The company showcases trust signals such as customer testimonials, awards, and Google reviews, supporting credibility. The website content is relevant and professionally presented, indicating a focus on quality and user experience. Partnerships and external domains linked are reputable and related to marketing and analytics. The absence of WHOIS data is a minor concern but does not detract significantly from the overall business credibility.

Security posture

The website enforces HTTPS with strong SSL configuration and includes essential security headers, indicating a good security baseline. Forms are secured and no sensitive data is exposed in the HTML. However, the lack of a published security policy, incident response contacts, and vulnerability disclosure mechanisms suggests gaps in transparency and preparedness. No known vulnerabilities or suspicious domains were detected. Privacy compliance is well addressed with GDPR-aligned policies and cookie consent mechanisms. The security score is good but could be improved by adding explicit security governance documentation and incident response details.

Recommendations

  1. Publish a detailed security policy page outlining security practices and commitments.
  2. Provide clear incident response contact information, including security@ or abuse@ email addresses.
  3. Implement and publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Enhance transparency around domain registration or consider updating WHOIS information for trust.
  5. Maintain and regularly audit security headers and SSL configurations to uphold strong security posture.

Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO plugin, leveraging Bootstrap for responsive design. It uses modern web fonts and custom JavaScript for enhanced user experience. The site is mobile-optimized with good accessibility features and fast loading times. Analytics usage is minimal with Matomo tracking scripts commented out, indicating privacy-conscious data collection. No outdated or vulnerable libraries were detected in the HTML source. The technical implementation supports a professional and scalable digital presence with opportunities for further modernization and security enhancements.
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.
