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

NDC Security is a well-established event organizer specializing in security-focused conferences for software developers, with the upcoming event scheduled for March 2026 in Oslo, Norway. The website reflects a professional and modern digital presence, leveraging contemporary web technologies such as React and Next.js, hosted behind Cloudflare for performance and security. The site includes comprehensive cookie consent mechanisms aligned with GDPR requirements, demonstrating a commitment to privacy compliance. However, explicit contact information, terms of service, and security policy documents are not present, which could be improved to enhance trust and legal clarity. The domain registration is consistent and long-standing, supporting the legitimacy of the business.

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. 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 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';…

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

NDC Security targets software developers interested in security, positioning itself as a key player in the niche of developer security conferences. The business model revolves around event organization and education, with revenue likely generated from ticket sales and sponsorships. The company benefits from a consistent brand and a strong digital footprint, including integration with marketing and analytics platforms like HubSpot and Google Analytics. The absence of direct contact details on the website suggests a focus on digital engagement channels. The partnership ecosystem includes major service providers for analytics and marketing but no explicit business partners are listed.

Security posture

The website demonstrates a solid security posture with HTTPS enforced, presence of multiple security headers, and no visible sensitive data exposure. The cookie consent banner is detailed and compliant with GDPR, covering necessary, functional, statistical, and marketing cookies with vendor disclosures. However, the lack of a published security policy, incident response plan, or vulnerability disclosure mechanism limits transparency and preparedness communication. DNSSEC is not enabled, which is a minor security gap. Overall, the site is secure but could benefit from enhanced security documentation and incident response readiness.

Recommendations

  1. Enable DNSSEC on the domain to strengthen DNS security and prevent spoofing.
  2. Publish a dedicated security policy and incident response page to improve transparency and preparedness.
  3. Add a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  4. Provide clear contact information, including security and general inquiries, to enhance trust and communication.
  5. Consider publishing terms of service to clarify legal terms and user obligations.

Notes

The website is built on a modern React/Next.js stack, ensuring good performance and SEO optimization. Hosting via Cloudflare provides CDN benefits and security features. The site is mobile-optimized and accessible, with proper meta tags and structured data for events. Analytics and marketing integrations are well implemented, using HubSpot and Google services. No outdated or vulnerable libraries were detected in the provided content. The site demonstrates good technical maturity with room for improvement in DNS security and legal documentation.
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.
