JSConf México is a community-driven technology conference focused on JavaScript and web development, held in Guadalajara, Mexico. The website promotes the 2025 edition of the conference, showcasing speakers, sponsors, and community partners. The business model revolves around event ticket sales and sponsorships, targeting front-end developers and the broader JavaScript community. The domain registration is recent but consistent with the event's timeline, and the site is hosted on modern infrastructure (Vercel) using Next.js technology. The website demonstrates a high level of digital maturity with excellent design, mobile optimization, and SEO practices.

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

  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 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • 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

JSConf México holds a strong position as a regional leader in JavaScript conferences, leveraging partnerships with major technology companies like AWS, Zillow, and Dropbox. The event attracts over 2,000 attendees and features 32 speakers, indicating a vibrant community presence. Revenue streams likely include ticket sales and tiered sponsorship packages. The conference fosters community engagement through partnerships with local and international tech groups. Growth potential is supported by consistent branding and a clear focus on the JavaScript ecosystem. The absence of detailed contact information and formal policies suggests room for operational maturity improvements.

Security posture

The website employs HTTPS with a valid SSL certificate and is hosted on a reputable platform (Vercel). However, it lacks explicit security headers such as Content-Security-Policy and Strict-Transport-Security, which could enhance protection against common web attacks. No incident response or vulnerability disclosure information is provided, limiting transparency in security management. No exposed sensitive data or vulnerable libraries were detected in the analysis. The site does not implement cookie consent mechanisms, which may pose compliance risks under privacy regulations. Overall, the security posture is adequate but could benefit from enhancements in headers, policies, and transparency.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen web security.
  2. Add a cookie policy page and deploy a consent mechanism to comply with privacy regulations and improve user trust.
  3. Publish an incident response plan or security policy page to increase transparency and readiness for security events.
  4. Consider creating a vulnerability disclosure or security.txt file to facilitate responsible reporting of security issues.
  5. Enhance contact information by providing dedicated security and support email addresses to improve communication channels.

Technical notes

Notes

The website is built using Next.js, a modern React framework, and hosted on Vercel, ensuring fast performance and scalability. The site is mobile-optimized with responsive design and good accessibility features. SEO is well addressed with proper meta tags and structured content. No CMS is detected, indicating a custom-built solution. The use of Vercel Analytics indicates minimal user tracking. The technical infrastructure is modern and robust, supporting a professional user experience. Opportunities exist to improve security headers and privacy compliance features to reduce technical risks.
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.
