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

7 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

    • High

      No SPF record found

      SPF helps prevent email spoofing

      What to do: Add SPF record: "v=spf1 include:_spf.yourmailprovider.com ~all"

  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"

    • 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';…

  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

Valero Energy Corp. holds a strong market position in the energy sector, offering refining and renewable energy products. The website's investor-focused content indicates a business model reliant on transparent financial reporting and shareholder engagement. The company leverages partnerships with Q4 Inc for digital investor relations services. The presence of comprehensive SEC filings and proxy statements signals regulatory compliance and corporate governance maturity. Social media integration and email alert subscriptions support stakeholder engagement. The domain age and WHOIS data confirm legitimacy and consistent corporate identity.

Security posture

The website enforces HTTPS and uses domain status locks to prevent unauthorized changes, indicating good baseline security. However, the absence of DNSSEC and explicit security headers such as Content Security Policy or HSTS reduces the overall security posture. No vulnerabilities or exposed sensitive data were detected. Forms include anti-CSRF tokens, enhancing input security. The lack of a published security policy or incident response contact limits transparency in security governance. Tracking scripts from WebTrends and Cloudflare Insights are present, with moderate user tracking levels. GDPR compliance is partially indicated by the privacy policy but lacks cookie consent mechanisms.

Recommendations

  1. Enable DNSSEC to enhance DNS security and prevent spoofing.
  2. Implement and configure security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a clear security policy and incident response contact information to improve transparency and trust.
  4. Add a cookie consent banner/mechanism to comply fully with GDPR and other privacy regulations.
  5. Regularly audit third-party scripts and tracking tools to minimize privacy risks and improve compliance.

Technical notes

Notes

The website is built on ASP.NET WebForms and uses Q4 Inc's investor relations platform, integrating multiple JavaScript libraries and widgets for dynamic content such as news, financial tables, and presentations. The use of PDF.js for embedded documents and Google Fonts for typography indicates modern web practices. Hosting appears to be managed via GoDaddy for domain registration and Q4 CDN for content delivery. Performance is moderate with good mobile optimization and accessibility features. The site uses anti-CSRF tokens in forms, enhancing security. However, the absence of explicit security headers and DNSSEC indicates areas for technical improvement. The site is well-structured with clear navigation and professional design.
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.
