Their AI-powered platform, ekoDNA®, enables life sciences companies to personalize customer experiences effectively. The company targets healthcare practitioners, patients, and life sciences organizations, positioning itself as a leader in healthcare marketing innovation. Technically, the website is built on WordPress with modern SEO and analytics tools integrated, including Yoast SEO and Google Analytics, and employs Cloudflare Turnstile for bot protection. The site demonstrates good mobile optimization, accessibility, and SEO practices. Security-wise, the website uses HTTPS and cookie consent mechanisms but lacks published security policies and incident response information, which are recommended for enhanced trust.

Overall, the site presents a strong business and technical profile with room for improvement in security transparency and domain registration clarity.

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

5 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 Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • 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

      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

Oi Digital Ltd operates in the healthcare marketing sector, offering AI-driven personalization platforms and marketing services. Their business model focuses on delivering targeted, meaningful content to healthcare professionals and patients, enhancing engagement and advocacy. The company leverages partnerships, such as with ekoDNA®, to expand its product offerings. The website content and structure indicate a medium-sized enterprise with a well-established market presence in the UK. Their digital maturity is evidenced by the use of advanced analytics and SEO tools. The absence of direct contact emails and phone numbers on the site suggests a preference for contact via forms or indirect channels. The company maintains a LinkedIn presence, supporting professional networking and brand visibility.

Security posture

The website enforces HTTPS and employs cookie consent management compliant with GDPR, indicating a baseline security posture. However, the absence of explicit security policies, incident response contacts, and security headers reduces the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the analysis. The use of Cloudflare Turnstile suggests protection against automated abuse. Recommendations include publishing a security policy, incident response information, and implementing additional security headers to strengthen defenses and user trust. The WHOIS domain registration inconsistency is a notable risk factor that should be addressed to avoid reputational damage.

Recommendations

  1. Publish a comprehensive security policy and incident response contact information on the website.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Clarify domain registration details and ensure WHOIS information is accurate and consistent with business identity.
  4. Regularly audit third-party scripts and plugins for vulnerabilities and update them promptly.
  5. Enhance transparency by providing direct company contact emails and phone numbers for customer and security inquiries.

Technical notes

Notes

The website is built on WordPress 7.0.2, utilizing the Yoast SEO plugin for search engine optimization and Google Analytics for visitor tracking. It uses modern JavaScript libraries such as Anime.js for animations and Cloudflare Turnstile for bot mitigation. The site is mobile-optimized with responsive design and good accessibility features. Performance is moderate, with caching and minification evident from loaded assets. The site uses structured data (JSON-LD) for SEO enhancement and Open Graph tags for social media integration. No major technical debt or outdated technologies were detected, but hosting provider details are not explicit. Overall, the technical infrastructure supports a professional and user-friendly web presence.
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.
