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

CoreFiling is a specialized technology company providing intelligent software and services focused on digital data collection and XBRL reporting solutions. Their flagship True North Data Platform addresses challenges faced by filers, data collectors, auditors, and software vendors, positioning them as a niche leader in the XBRL ecosystem. The website reflects a mature digital presence with professional design, structured data, and clear contact information, supporting their market credibility. Technically, the website is built on WordPress with the Divi theme, leveraging modern JavaScript libraries and analytics tools such as Google Analytics and Google Tag Manager. The site is mobile-optimized and SEO-friendly, though some accessibility features could be enhanced. Security posture is solid with HTTPS enforced and cookie consent implemented, but lacks some advanced security headers and explicit security policies. The absence of publicly available WHOIS data introduces some uncertainty regarding domain registration transparency, though the overall professional presentation and consistent branding mitigate concerns. No signs of blocking or WAF interference were detected, allowing full content analysis. Overall, CoreFiling demonstrates a strong business and technical foundation with room for improvement in privacy disclosures and security policy transparency to enhance trust and compliance.

  3. (c) Business continuity, backups and crisis management: Not visible from outside
  4. (d) Supply chain security: Not visible from outside

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

4 findings rated critical or high. Fix these first.

  1. 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"

  2. 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

  3. 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 SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

  4. DNS health

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

    • High

      Weak SPF Policy

      SPF record has permissive policy allowing any server to send email

      What to do: Use -all or ~all qualifier for better email security

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

CoreFiling operates in the technology sector, specializing in XBRL and digital reporting software and services. Their business model centers on providing SaaS platforms, developer tools, and consulting/training services to a targeted audience of financial filers, auditors, and software vendors. The company maintains a medium-sized profile with a focused market niche, leveraging partnerships and open-source tools to extend their ecosystem. Their digital presence supports lead generation and customer engagement through downloads, case studies, and blog content. The company’s strategic positioning as an XBRL specialist offers competitive advantages in regulatory compliance and data standardization markets.

Security posture

The website enforces HTTPS and implements cookie consent mechanisms, indicating awareness of data protection and privacy regulations. However, the lack of security headers such as Content-Security-Policy and absence of a published security or incident response policy reduce the overall security maturity. No vulnerabilities or exposed sensitive data were detected in the analyzed content. The missing WHOIS transparency slightly impacts trust but does not indicate malicious intent. The site would benefit from publishing a vulnerability disclosure policy and enhancing security headers to align with best practices and regulatory expectations.

Recommendations

  1. Publish a comprehensive privacy policy and terms of service pages accessible from the main navigation or footer.
  2. Implement and publish security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Create and maintain a vulnerability disclosure or security.txt file to facilitate responsible reporting.
  4. Enhance accessibility features to improve compliance with standards such as WCAG.
  5. Seek to clarify domain registration details or use a registrar that provides transparent WHOIS data to improve 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.
