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

6 findings rated critical or high. Fix these first.

  1. DNS health

    DNS sends visitors and email to the right servers. Misconfigured records can cause outages or let someone redirect your traffic.

    • Critical

      DNS Resolution Failed

      Unable to resolve domain A records

      What to do: Verify domain is properly configured and not expired

  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 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';…

  3. 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

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

NiSource operates in the energy sector, providing natural gas and electric services to a large customer base in six states. Its business model focuses on utility service delivery combined with sustainability initiatives and community investment. The company maintains investor relations and corporate governance transparency, indicating a publicly accountable entity. Subsidiaries include NIPSCO and Columbia Gas. The website targets customers, investors, suppliers, and community stakeholders, supporting multiple business functions including customer programs, regulatory information, and careers. The digital ecosystem includes subdomains for investors and careers, reflecting a segmented approach to stakeholder engagement. The company leverages third-party analytics and marketing tools with user consent, balancing business intelligence needs with privacy compliance.

Security posture

The website enforces HTTPS and uses cookie consent banners to comply with privacy regulations. Google Tag Manager and Analytics are integrated with user consent management, reducing privacy risks. However, no explicit security policy, incident response contacts, or vulnerability disclosure mechanisms were found, which are best practices for corporate websites. Security headers were not detected in the provided data, suggesting room for improvement. No exposed sensitive data or vulnerable libraries were identified. Overall, the security posture is good but could be enhanced by publishing security policies, incident response information, and implementing additional HTTP security headers.

Recommendations

  1. Implement and publish a dedicated security policy and incident response contact information on the website.
  2. Add a security.txt file or vulnerability disclosure page to encourage responsible reporting of security issues.
  3. Enhance HTTP security headers such as Content-Security-Policy, X-Frame-Options, and X-XSS-Protection to improve protection against common web attacks.
  4. Provide clear company contact information including verified emails and phone numbers to improve trust and user support.
  5. Conduct a WHOIS domain registration update or verification to ensure transparency and reduce suspicion from missing WHOIS data.

Technical notes

Notes

The website is built on the Sitefinity CMS platform version 15.2.8422.0, indicating a modern and enterprise-grade content management system. It uses jQuery 1.12.1, Google Tag Manager, and Flowplayer for video content, along with Cloud.Typography for fonts. The site is mobile responsive with good SEO meta tags and Open Graph data for social sharing. Performance is moderate with some reliance on external CDNs and cloud font services. Accessibility features are basic but present. The technical stack is stable and supports the business needs effectively, though updating jQuery to a more recent version could improve security and performance. Hosting provider details were not identified from the data.
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.
