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 anonymous website visitors and converts them into actionable sales leads, targeting sales and marketing professionals primarily in Europe. The company positions itself as a trusted partner with ISO 27001 certification and a strong focus on GDPR compliance. Their business model is subscription-based SaaS, serving medium-sized enterprises and sales teams. Technically, the website is built on WordPress with modern frameworks like Bootstrap and uses Matomo for privacy-conscious analytics. The site is well-optimized for mobile and SEO, with a professional design and clear navigation. Security posture is strong with HTTPS, security headers, and secure forms, though public security policies and incident response contacts are not published. Overall, the website demonstrates a mature digital presence with good security and privacy practices. However, the lack of WHOIS registration transparency and absence of a public vulnerability disclosure policy slightly reduce trust. Strategic improvements in transparency and incident response communication would enhance their security posture and business credibility.

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 17 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 in the technology sector, focusing on sales intelligence and lead generation for B2B clients. Their competitive advantage lies in real-time visitor identification and CRM integration, enabling sales teams to act on leads efficiently. The company targets medium-sized businesses and sales professionals, leveraging certifications and customer testimonials to build trust. Their marketing ecosystem includes partnerships and use of privacy-friendly analytics. Growth indicators include multilingual support and a comprehensive content strategy. The absence of public WHOIS data suggests privacy protection, which is common but reduces transparency.

Security posture

The website enforces HTTPS and implements key security headers, reflecting a strong baseline security posture. Forms are secured with validation, and no sensitive data is exposed in the HTML. The use of Matomo analytics indicates a privacy-conscious approach. However, the lack of a published security policy, incident response plan, or security.txt file limits transparency and readiness communication. No vulnerabilities or outdated libraries were detected in the provided content. Overall, the security maturity is good but could be improved with formal disclosure and response mechanisms.

Recommendations

  1. Publish a public vulnerability disclosure policy and security.txt file to facilitate responsible reporting.
  2. Add explicit incident response contact information, such as a dedicated security email address.
  3. Enhance WHOIS transparency if possible to improve domain trustworthiness.
  4. Continue maintaining GDPR compliance and update privacy policies regularly.
  5. Implement ongoing security awareness and communication to strengthen trust with customers.

Technical notes

Notes

The website uses WordPress CMS with Yoast SEO plugin and Bootstrap CSS framework, ensuring modern and responsive design. Fonts like Open Sans and Sofia Pro are used for branding consistency. Analytics are handled by Matomo, a privacy-focused tool. The site loads efficiently with preloaded fonts and optimized assets. Accessibility and SEO are well addressed with proper meta tags and hreflang for multilingual support. No hosting provider details were found, but the site uses HTTPS with strong SSL configuration. Technical debt appears low, and the infrastructure supports a professional B2B SaaS offering.
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.
