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

Pearl Diver, operated by Blackpearl Group Limited, is a sophisticated SaaS platform specializing in prospect identification and intent data solutions for B2B and B2C marketers. The company positions itself as a market leader with over 1,200 customers and strong positive reviews on G2, emphasizing its ability to improve marketing ROI by targeting high-intent buyers beyond traditional ad platforms. The website reflects a mature digital presence with modern design, clear messaging, and comprehensive service offerings. Technically, the site leverages Webflow CMS, HubSpot marketing and analytics tools, Microsoft Clarity, and Google Tag Manager, indicating a well-integrated marketing technology stack. The site is performant, mobile-optimized, and SEO-friendly, with appropriate use of meta tags and structured content. Privacy and cookie policies are prominently implemented, supporting GDPR compliance. From a security perspective, the site enforces HTTPS and uses several security best practices, though explicit security headers and incident response information are not published. No vulnerabilities or exposed sensitive data were detected. The WHOIS data is unavailable due to privacy protection, which is justified for this business type. Overall, the security posture is strong but could be enhanced by publishing security policies and vulnerability disclosure mechanisms. The overall risk assessment is low, with the site demonstrating professionalism, trustworthiness, and compliance. Strategic recommendations include enhancing security header implementation, publishing incident response contacts, and maintaining regular audits of third-party scripts to sustain security and compliance standards.

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. 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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

  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

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

Pearl Diver operates in the technology sector, focusing on intent data and prospect identification to optimize marketing and sales efforts. Its business model is SaaS-based, targeting marketers and sales teams in both B2B and B2C segments. The company leverages a strong partnership ecosystem, including HubSpot and Blackpearl domains, and maintains a credible market position supported by customer testimonials and G2 reviews. Revenue streams likely include subscription fees for platform access and API integrations. Growth indicators include a sizable customer base and active marketing campaigns. The company emphasizes compliance and data privacy, aligning with industry standards.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, cookie consent mechanisms, and use of reputable third-party marketing and analytics services. No critical vulnerabilities or exposed sensitive data were found. However, the absence of a published security policy, incident response contacts, and vulnerability disclosure program represents a compliance gap. The site lacks explicit security headers such as X-Frame-Options and X-Content-Type-Options, which are recommended to mitigate common web attacks. Overall, the security maturity is good but can be improved by formalizing security governance and transparency.

Recommendations

  1. Implement and verify comprehensive security headers including X-Frame-Options and X-Content-Type-Options.
  2. Publish a dedicated security policy and incident response contact information on the website.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  4. Conduct regular security audits of third-party scripts and integrations to prevent supply chain risks.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

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.
