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

Pearl Diver, operated by Blackpearl Group Limited, is a New Zealand-based B2B SaaS company specializing in intent data and prospect identification solutions for marketers and sales teams. The platform leverages real-time buyer signals beyond traditional ad platforms to improve targeting accuracy, reduce wasted ad spend, and increase conversion rates. The company is well-positioned in the marketing technology sector with a strong user base and positive market reputation, supported by numerous customer testimonials and G2 reviews. Technically, the website is built on Webflow CMS and integrates advanced marketing and analytics tools such as HubSpot, Microsoft Clarity, and Google Tag Manager. The site demonstrates excellent design quality, mobile optimization, and SEO practices, ensuring a smooth user experience and effective digital presence. Security-wise, the site enforces HTTPS and uses controlled third-party scripts, though it lacks some advanced security headers and a published security policy. The security posture is solid with no visible vulnerabilities or exposed sensitive data. Privacy compliance is well addressed with comprehensive privacy and cookie policies, including GDPR and CCPA considerations. However, the WHOIS data is privacy protected, limiting transparency on domain registration details, though this is common and justified for commercial SaaS providers. Overall, Pearl Diver presents a professional, trustworthy, and technically mature online presence with minor recommendations to enhance security headers and incident response transparency. The business is credible and well-aligned with its market claims, making it a reliable partner for marketers seeking intent data solutions.

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. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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 competitive marketing technology space, focusing on intent data to provide actionable insights for sales and marketing teams. Its competitive advantage lies in real-time buyer signal tracking from a vast network of websites, enabling precise targeting beyond traditional ad platforms. The business model is subscription-based SaaS, targeting medium to large enterprises and growth-focused marketers. Revenue streams likely include tiered subscription plans and API integrations. The company maintains a strong partnership ecosystem with Blackpearl Group and related domains, enhancing service delivery and customer support. Growth indicators include over 1,200 active marketers and positive G2 ratings. Strategic observations highlight the company's emphasis on reducing ad spend waste and improving ROI, positioning it as an innovative solution in the intent data market.

Security posture

Pearl Diver demonstrates a mature security posture with enforced HTTPS, absence of exposed sensitive data, and use of reputable third-party analytics and marketing platforms. The presence of cookie consent mechanisms and comprehensive privacy policies indicates good privacy practices. However, the site lacks explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options, which are recommended to mitigate common web vulnerabilities. No incident response or vulnerability disclosure information is published, which could be improved to enhance transparency and readiness. The WHOIS privacy protection is justified but limits external verification of domain ownership. Overall, the security maturity is good with room for enhancements in header policies and incident response documentation.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to strengthen web security.
  2. Publish a formal security policy and incident response contact information to improve transparency and trust.
  3. Consider adding a vulnerability disclosure program or security.txt file to facilitate responsible reporting.
  4. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.
  5. Enhance monitoring and logging capabilities to detect and respond to potential security incidents promptly.

Technical notes

Notes

The website is built using Webflow CMS, leveraging modern web technologies including JavaScript, CSS, and Google Fonts. It integrates multiple marketing and analytics tools such as HubSpot (for messaging, forms, analytics, and ads pixel), Microsoft Clarity for user behavior tracking, and Google Tag Manager for tag management. Hosting is provided via Webflow's CDN, ensuring fast content delivery and good performance. The site is mobile-optimized with responsive design and accessibility considerations. SEO is well addressed with proper meta tags and Open Graph data. Technical risks are minimal, but the absence of some security headers and incident response mechanisms represent areas for modernization and risk mitigation.
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.
