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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  3. 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 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';…

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

Core Laboratories holds a strong market position as an essential service provider in the energy sector, focusing on reservoir evaluation and production enhancement. Their competitive advantage lies in proprietary technologies and a global footprint that supports major, national, and independent oil companies. The business model centers on delivering specialized laboratory and field services, with revenue streams likely derived from service contracts, consortium memberships, and product sales. The company targets technically sophisticated clients requiring advanced reservoir analytics and inspection services. Growth indicators include recent lab openings and ongoing consortium activities. The partnership ecosystem includes client portals and digital tools enhancing customer engagement and operational efficiency.

Security posture

The website demonstrates a solid security maturity level with enforced HTTPS, comprehensive security headers, and secure client portal access via two-factor authentication. Privacy compliance is supported by clear privacy and cookie policies with consent mechanisms. However, the absence of a dedicated security policy page, vulnerability disclosure, and direct incident response contacts suggests room for improvement in transparency and readiness. No visible vulnerabilities or exposed sensitive data were found, indicating good operational security practices. The security culture appears proactive but could benefit from formalized documentation and communication of security frameworks and incident handling procedures.

Recommendations

  1. Develop and publish a detailed security policy page outlining security frameworks and controls.
  2. Implement and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  3. Provide clear incident response contact channels such as security@ or abuse@ email addresses.
  4. Enhance website accessibility features to meet higher compliance standards.
  5. Regularly review and update third-party plugins and scripts to mitigate potential vulnerabilities.

Notes

The website leverages a robust WordPress CMS with modern themes and plugins, including Elementor and Visual Composer for content management and layout. Hosting on WPEngine provides a stable and scalable environment. Performance is moderate with good mobile responsiveness and SEO optimization. The technical stack includes advanced analytics and marketing tools such as Google Analytics and MonsterInsights. There is some technical debt risk from multiple third-party plugins, which requires ongoing maintenance. Opportunities exist to streamline scripts and enhance accessibility compliance. Overall, the technical infrastructure supports the business needs effectively with room for modernization in security transparency and performance tuning.
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.
