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 company data to enhance sales and marketing efforts. Positioned as an established player in the sales enablement market, SalesViewer targets B2B sales teams and marketing professionals with a SaaS subscription model. The website demonstrates a high level of digital maturity, leveraging WordPress CMS, modern frameworks like Bootstrap, and privacy-conscious analytics via Matomo. Security posture is strong with HTTPS enforcement and security headers, though the absence of a public security policy and incident response contacts suggests room for improvement. Overall, the site is professional, well-optimized for SEO and mobile, and compliant with GDPR regulations. The lack of WHOIS data slightly reduces trust but does not detract from the business credibility evident on the site.

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

4 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

      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

      SSL Certificate Expires Soon

      SSL certificate expires in 12 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

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 in the technology sector, focusing on B2B sales and marketing solutions. Their competitive advantage lies in detailed visitor identification and CRM integration capabilities. The business model is subscription-based SaaS, targeting medium-sized enterprises primarily in the Netherlands and Europe. The company showcases trust signals such as ISO 27001 certification, customer testimonials, and press mentions. Their partnership ecosystem includes integrations with CRM platforms and marketing tools. Growth indicators include active content marketing, Google reviews, and a professional online presence. Strategic observations suggest continued investment in privacy and security compliance will enhance market position.

Security posture

The website exhibits a mature security posture with HTTPS, robust security headers, and secure form handling. No vulnerabilities or exposed sensitive data were detected. However, the absence of a dedicated security policy page, vulnerability disclosure program, or security.txt file indicates a gap in transparency and incident response readiness. GDPR compliance is well addressed with clear privacy and cookie policies and consent mechanisms. The use of Matomo analytics reflects a privacy-conscious approach. Overall, the security culture appears solid but could benefit from enhanced communication of security practices and incident response channels.

Recommendations

  1. Publish a dedicated security policy page outlining security practices and compliance.
  2. Implement a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact information for security issues.
  4. Regularly review and update privacy and cookie policies to maintain GDPR compliance.
  5. Enhance WHOIS transparency if possible to improve domain trustworthiness.

Notes

The website is built on WordPress CMS with Bootstrap framework, ensuring responsive design and good accessibility. Performance is optimized with preloaded fonts and efficient CSS usage. SEO is enhanced by Yoast SEO plugin and proper meta tags. Analytics are handled by Matomo, supporting privacy compliance. No deprecated or vulnerable libraries were detected. Hosting provider details are not explicit but the site uses HTTPS with strong SSL configuration. Technical debt appears low, with modern best practices followed. Opportunities exist to improve incident response readiness and domain registration transparency.
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.
