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

NDC Porto 2025 is a well-established software developer conference scheduled for October 2025 in Porto, Portugal. The website serves as an event information and registration platform targeting software developers. It leverages modern web technologies including React and Next.js, and integrates with third-party services such as HubSpot and Google Analytics for marketing and analytics purposes. The site is hosted behind Cloudflare, ensuring good performance and security. The presence of a comprehensive cookie consent banner and privacy policy indicates a strong commitment to GDPR compliance. However, explicit terms of service and security policy pages are not found, and no direct contact information is provided on the homepage, which could be improved for better user trust and support. Overall, the website demonstrates a solid technical infrastructure and a professional presentation suitable for its audience and business model.

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.

Breach exposure

Leaked credentials and lookalike domains from OffSeq Breach. The counts are free; the detailed lists are paid add-ons.

Dark web exposure

Add-on

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

No leaked records found

Breach holds no records for ndcporto.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 business operates in the technology sector, focusing on organizing conferences for software developers. It has a medium-sized presence with a clear market position as a reputable event organizer. The business model revolves around event ticket sales, workshops, and networking opportunities. The website content and metadata emphasize the event's dates, location, and target audience. The use of HubSpot and Google Marketing Platform suggests active marketing and lead generation efforts. The absence of parent or subsidiary company information indicates an independent operation. The partnership ecosystem is not explicitly detailed on the site. Growth indicators include the multi-day event format and consistent branding across digital assets.

Security posture

The website enforces HTTPS with an excellent SSL configuration and employs Cloudflare for CDN and DDoS protection. Security headers such as Strict-Transport-Security and X-Content-Type-Options are present, enhancing security posture. The cookie consent mechanism is robust and GDPR compliant. No vulnerabilities or exposed sensitive data were detected in the HTML content. However, the lack of a published security policy, incident response contact, and vulnerability disclosure mechanism (e.g., security.txt) represents a gap in security transparency and readiness. Accessibility features are basic and could be enhanced to meet higher compliance standards. Overall, the security posture is strong but could benefit from improved transparency and incident management information.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and prevent spoofing.
  2. Publish a security.txt file to provide a clear vulnerability disclosure channel.
  3. Add explicit security policy and incident response information on the website.
  4. Enhance accessibility features to improve compliance and user experience.
  5. Provide clear contact information including emails and phone numbers for support and security inquiries.

Technical notes

Notes

The website is built using modern web technologies including React and Next.js, ensuring good performance and scalability. It uses Cloudflare for hosting and CDN, which contributes to fast loading times and security. Integration with HubSpot and Google Tag Manager supports marketing and analytics needs. The site is mobile optimized with responsive design and includes SEO best practices such as meta tags and Open Graph data. No CMS is explicitly detected, suggesting a custom or static site generation approach. The technical implementation is solid with no visible technical debt or deprecated libraries. Opportunities exist to improve accessibility and add more comprehensive security 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.
