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

SalesViewer GmbH operates a technology platform focused on identifying anonymous website visitors to generate B2B leads and enhance sales intelligence. The company positions itself as a market leader with a strong emphasis on data protection compliance, including GDPR and CCPA. Their platform offers a comprehensive suite of features aimed at improving sales processes and customer acquisition for B2B teams. Technically, the website is built on WordPress with advanced SEO and analytics integrations, including Matomo and Google Analytics, supported by a robust cookie consent mechanism. However, a critical security gap exists due to the absence of a valid SSL certificate and lack of modern TLS protocols, which undermines secure data transmission. The overall security posture is moderate with room for significant improvements in encryption and security headers. The website demonstrates high professionalism, excellent content quality, and strong trust indicators, supported by numerous customer case studies and awards.

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 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

SalesViewer GmbH targets B2B sales and marketing teams, offering a SaaS model for lead generation and sales intelligence. The company leverages partnerships and integrations with major platforms and maintains a strong presence in the technology sector. Their business model focuses on providing actionable visitor data to accelerate sales cycles and gain competitive advantages. The company showcases a broad customer base including market leaders and international brands, supported by a consistent and professional brand image. Their marketing and advertising strategies utilize multiple ad networks and tracking pixels, ensuring effective outreach and retargeting capabilities. The company’s compliance with GDPR and CCPA, along with transparent cookie management, reflects a mature approach to privacy and data protection.

Security posture

The current security posture of SalesViewer.com reveals critical vulnerabilities, primarily the lack of a valid SSL certificate and disabled TLS protocols, which expose users to potential data interception risks. While the domain has a well-configured SPF record and a basic DMARC policy, the absence of HSTS and other security headers reduces the overall security effectiveness. The use of Borlabs Cookie for consent management and adherence to GDPR and CCPA standards indicates a strong compliance culture. However, the website should urgently address its encryption and transport security to protect user data and maintain trust. Incident response and security policy documentation are not publicly found, suggesting an area for improvement in transparency and readiness.

Recommendations

  1. Implement and maintain a valid SSL/TLS certificate to enable secure HTTPS connections.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) and disable outdated protocols to enhance transport security.
  3. Configure HTTP security headers including HSTS with preload and includeSubDomains options.
  4. Publish clear security policies and incident response procedures to improve transparency and readiness.
  5. Regularly audit and update cookie and tracking consent mechanisms to ensure ongoing compliance with privacy regulations.
Technical notes

Notes

The website is built on WordPress CMS with Yoast SEO plugin for optimization and uses Matomo and Google Analytics for visitor tracking. It employs Borlabs Cookie for comprehensive cookie consent management and OptinMonster for marketing campaigns. The hosting is provided by Hetzner with DNS configured properly but lacks DNSSEC and CAA records. Performance is moderate with a page load time of approximately 5.8 seconds and extensive use of SVG images and lazy loading techniques. The absence of SSL/TLS is a significant technical risk. The site is well-structured with JSON-LD structured data for enhanced SEO. Overall, the technical infrastructure is modern but requires urgent 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.
