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

CSC operates as an established enterprise providing corporate tax software solutions under the Corptax brand. Their offerings focus on automating corporate tax reporting, streamlining tax workflows, and delivering advanced tax planning and data analytics tools. The company targets corporations and tax professionals seeking efficient tax compliance and reporting technologies. CSC positions itself as a leader in tax technology with a comprehensive suite of services including consulting and professional support. Technically, the website leverages modern frameworks such as Bootstrap and jQuery, integrates advanced analytics and marketing tools like Google Tag Manager and Optimizely, and is hosted on Microsoft Azure infrastructure, indicating a mature digital presence. Security-wise, the site enforces HTTPS, employs reCAPTCHA for form protection, and uses cookie consent mechanisms aligned with GDPR requirements. However, the absence of WHOIS domain registration data raises concerns about domain legitimacy and transparency, which slightly impacts overall trust. No critical vulnerabilities or security policy disclosures are publicly evident, suggesting a moderate security posture. Overall, CSC's website reflects a professional, business-focused platform with good technical and privacy compliance, but domain registration opacity warrants further verification.

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

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.

    • 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

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

CSC's market positioning as a provider of corporate tax software and compliance solutions places it in the technology and finance sectors, serving enterprise clients globally. Their business model is B2B, focusing on software sales, consulting, and professional services. The company benefits from a strong partnership ecosystem, including digital brand and cyber risk services via cscdbs.com and industry events like the Corptax CONNECT Conference. Revenue streams likely include software licensing, subscription services, and consulting fees. The website content and navigation indicate a mature organization with consistent branding and a clear focus on tax technology innovation. Growth indicators include active resource sharing, webinars, and client testimonials. Strategic observations highlight the importance of maintaining domain registration transparency to reinforce credibility.

Security posture

The website demonstrates a good security maturity level with HTTPS enforcement, use of Google reCAPTCHA to mitigate automated abuse, and cookie consent aligned with GDPR. However, explicit security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options are not visibly configured, representing an area for improvement. No public incident response or vulnerability disclosure information is available, which may limit transparency in security incident handling. The absence of a security.txt file further reduces visibility into security practices. No exposed sensitive data or vulnerable libraries were detected in the analyzed content. Overall, the security posture is solid but could be enhanced by adopting additional HTTP security headers and publishing incident response details.

Recommendations

  1. Implement and enforce Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options HTTP headers to strengthen security.
  2. Publish a clear security policy and incident response plan accessible on the website to improve transparency and trust.
  3. Establish a vulnerability disclosure program and consider adding a security.txt file to facilitate responsible reporting.
  4. Verify and update WHOIS domain registration information to ensure transparency and enhance domain legitimacy.
  5. Regularly audit third-party scripts and dependencies to mitigate risks from external libraries and tracking tools.

Technical notes

Notes

The website is built on a modern technology stack including Bootstrap for responsive design, jQuery for DOM manipulation and validation, and integrates advanced marketing and analytics tools such as Google Tag Manager and Optimizely. Hosting on Microsoft Azure suggests reliable infrastructure with scalability. Performance is moderate with good mobile optimization and accessibility features implemented. SEO is supported by comprehensive meta tags, Open Graph data, and structured JSON-LD schema markup. The site uses cookie consent management via OneTrust, indicating compliance with privacy regulations. Technical risks include reliance on multiple third-party scripts which require ongoing security monitoring. Opportunities exist to enhance security headers and improve domain registration transparency to reduce technical debt and strengthen 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.
