60/100

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

SLB is a global energy technology company focused on driving innovation for a balanced planet. Their website showcases a comprehensive portfolio of solutions spanning decarbonization, digital transformation, and traditional oil and gas services. The company targets energy industry professionals, investors, partners, and job seekers, positioning itself as a market leader with extensive service offerings and a strong sustainability commitment. Technically, the website employs modern technologies such as jQuery, Brightcove video, Coveo search, and integrates multiple analytics and marketing tools. The site is well-designed, mobile-optimized, and offers rich content with clear navigation. However, the security posture is weakened by an invalid or missing SSL certificate and lack of HTTPS support, which is a critical issue. Privacy compliance is strong with clear policies and cookie consent mechanisms. Overall, the site reflects a mature enterprise with good business credibility but requires urgent security improvements to protect user data and maintain trust.

Scanned

NIS2 and GDPR posture

Both readouts depend on the site's pages, which could not be loaded in this scan.

Priority findings

1 finding 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.

    • 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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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

SLB operates in the energy sector with a focus on technology and services that enable decarbonization, digital transformation, and operational optimization. Their business model includes product sales, consulting, and digital platform services. The company maintains a global presence with dedicated subdomains for careers, investors, software, and commerce. Partnerships with specialized entities like Subsea Services Alliance and training providers enhance their ecosystem. The website content and structure indicate a well-established enterprise targeting a professional audience with a strong emphasis on sustainability and innovation. The presence of extensive product and service categories suggests diversified revenue streams and a comprehensive market approach.

Security posture

The website implements several security best practices including a robust Content Security Policy, X-Frame-Options, X-XSS-Protection, and secure cookie attributes. It uses Google reCAPTCHA to mitigate bot activity and integrates with trusted third-party services for analytics and marketing. However, the absence of a valid SSL certificate and lack of HTTPS support are critical vulnerabilities that expose users to potential data interception and reduce overall trust. The malformed CAA DNS records and lack of OCSP stapling further indicate areas for improvement. No direct incident response or vulnerability disclosure information is available, which may impact incident handling readiness. Overall, the security posture is moderate but requires immediate remediation of SSL/TLS issues.

Recommendations

  1. Obtain and deploy a valid SSL/TLS certificate to enable HTTPS across the entire site.
  2. Enable modern TLS protocols (TLS 1.2 or 1.3) and disable insecure versions.
  3. Correct and validate CAA DNS records to ensure proper certificate issuance control.
  4. Implement OCSP stapling and session resumption to improve security and performance.
  5. Publish clear incident response and vulnerability disclosure policies to enhance transparency and readiness.
Technical notes

Notes

The website is built on a modern technology stack including jQuery, Brightcove for video streaming, Coveo for search capabilities, and integrates multiple analytics and marketing platforms such as Google Analytics, Microsoft Clarity, Facebook Pixel, and Emarsys. The CMS appears to be Sitecore, inferred from CoveoForSitecore references. Hosting is likely on Microsoft Azure based on IP and domain data. The site is mobile-optimized with responsive design and good navigation clarity. Performance data is not available, but the use of CDNs and modern libraries suggests moderate to good performance. Technical debt is minimal from the visible code, but the critical SSL/TLS misconfiguration poses a significant risk to business operations and user trust.
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.
