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

Exonar Ltd is a UK-based technology company specializing in advanced data discovery software that indexes both structured and unstructured data at scale. The company targets information security, governance, risk, compliance, and IT operations professionals, offering solutions that reduce risk and uncover business value from data. Recently acquired by NowVertical Group, Exonar maintains a strong market position with notable clients such as GSK and Lloyds. The website reflects a professional and consistent brand image with comprehensive content and clear navigation. Technically, the website is built on the HubSpot CMS platform, leveraging modern marketing and analytics tools including Google Analytics, Hotjar, and LinkedIn Insight. The site is mobile-optimized and performs moderately well, though there is room for improvement in accessibility and security header implementation. Privacy and cookie policies are present with consent mechanisms, indicating good privacy compliance practices. From a security perspective, the site enforces HTTPS and avoids exposing sensitive data in its HTML content. However, the absence of explicit security policies, incident response information, and vulnerability disclosure mechanisms suggests areas for enhancement. The lack of WHOIS data for the domain raises some trust concerns, although the professional presentation and business information mitigate this to some extent. Overall, Exonar's digital presence is solid with good content quality and privacy compliance, but improvements in transparency and security best practices would strengthen its 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

4 findings rated critical or high. Fix these first.

  1. 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

  2. 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"

  3. 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

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

Exonar operates in the enterprise data discovery software market, focusing on risk reduction, compliance, and operational efficiency. Its acquisition by NowVertical Group suggests strategic growth and integration into a broader product suite. The company leverages partnerships and showcases reputable clients, enhancing its market credibility. Revenue streams likely include software licensing, subscriptions, and professional services. The target customer segments are mid to large enterprises with significant data management needs. The website's marketing and analytics infrastructure indicate a mature digital strategy supporting lead generation and customer engagement.

Security posture

The website demonstrates a moderate to good security maturity level with enforced HTTPS and no visible exposure of sensitive data. However, the absence of security headers and lack of published security policies or incident response plans indicate gaps in security transparency and defense-in-depth. No vulnerability disclosures or security.txt files were found, limiting external reporting channels. Compliance with GDPR is supported by privacy and cookie policies with consent mechanisms. The overall security culture appears professional but could benefit from enhanced communication and technical controls to improve trust and resilience.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response page to improve transparency.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection.
  3. Publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  4. Conduct regular audits of third-party scripts and dependencies to mitigate potential vulnerabilities.
  5. Enhance accessibility features to improve compliance and user experience for all visitors.

Technical notes

Notes

The website is built on the HubSpot CMS platform, utilizing modern JavaScript libraries and marketing tools such as Google Analytics, Hotjar, and LinkedIn Insight. The site is mobile responsive with good SEO optimization and clear navigation. Performance is moderate, with potential improvements in load speed and accessibility. The technical infrastructure supports effective marketing and analytics but lacks some security best practices like security headers. Overall, the technical implementation is solid but could be enhanced with additional security and accessibility measures.
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.
