NDC Copenhagen is a well-established developer conference held annually in Copenhagen, targeting software developers and technology professionals. The website effectively promotes the 2025 event with clear information about dates, venue, and offerings such as workshops and speakers. The business model centers on event organization and ticket sales, positioning NDC Copenhagen as a significant player in the regional tech event market. Technically, the site leverages modern web technologies including React and Next.js, supported by Cloudflare for hosting and CDN services, ensuring fast performance and good mobile optimization. The integration of HubSpot and Facebook Pixel indicates a mature marketing and analytics setup. Security-wise, the site enforces HTTPS, employs standard security headers, and provides a comprehensive cookie consent mechanism compliant with GDPR.

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.

Dark web exposure

Add-on

Leaked records that mention cphdevfest.com, from OffSeq Breach.

No leaked records found

Breach holds no records for cphdevfest.com right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company operates in the technology sector, focusing on developer events and conferences. Its competitive advantage lies in its established brand and consistent event delivery since 2018. Revenue streams likely include ticket sales, sponsorships, and workshops. The target customers are software developers and tech enthusiasts primarily in Denmark and the broader Nordic region. The partnership ecosystem includes marketing and analytics providers like HubSpot and Cloudflare. The website content and structure support growth by providing clear event information and easy navigation. Strategic observations suggest enhancing contact transparency and publishing formal policies to strengthen trust and compliance.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers implemented. The use of Cloudflare provides additional protection and performance benefits. The cookie consent banner is comprehensive and GDPR compliant, indicating good privacy practices. No critical vulnerabilities or exposed sensitive data were detected in the HTML content. However, the absence of a published security policy, incident response contacts, or vulnerability disclosure mechanisms limits the site's security transparency and readiness. Recommendations include enabling DNSSEC, publishing a security.txt file, and providing explicit security contact information to improve incident response capabilities and stakeholder trust.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish a security.txt file at the root domain to facilitate vulnerability reporting.
  3. Add explicit security and incident response policy pages with contact details.
  4. Provide clear company contact information including emails and phone numbers on the website.
  5. Regularly review and audit third-party scripts and tracking tools for security and privacy compliance.

Technical notes

Notes

The website is built on a modern React and Next.js framework, ensuring server-side rendering and good SEO performance. Hosting and DNS are managed via Cloudflare, providing CDN and security benefits. The site uses HubSpot for marketing automation and analytics, alongside Facebook Pixel for advertising tracking. Performance is fast with good mobile responsiveness and accessibility features. Meta tags and structured data (JSON-LD) are properly implemented for SEO and social sharing. No CMS like WordPress or Drupal is detected, indicating a custom or headless architecture. The technical stack is modern and well-maintained, supporting scalability and user experience.
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.
