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

ACM SIGWEB is a specialized professional group under the Association for Computing Machinery focused on hypertext and web technologies. It serves an academic and professional audience by sponsoring multiple conferences and fostering research and community engagement in linked information systems and the Web. The website reflects a mature, medium-sized organization with a clear focus on technology and research dissemination. Technically, the site is built on Joomla CMS with Bootstrap and jQuery, providing a moderate performance and good mobile optimization. Security posture is adequate with HTTPS enabled but lacks advanced security headers and privacy compliance documentation. The absence of WHOIS data reduces domain trust slightly, but the ACM affiliation strongly supports legitimacy. Overall, the site is professional, content-rich, and trustworthy for its target audience.

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

9 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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  3. 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 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';…

  4. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • 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

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 · found on this site
  • 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

SIGWEB occupies a niche academic market within computing, leveraging ACM's brand and infrastructure. Its business model is non-profit and community-driven, focusing on conference sponsorship and knowledge sharing. The site targets researchers, academics, and professionals in web and hypertext technologies. Growth indicators include multiple upcoming conferences and active community programs. Partnerships are primarily internal to ACM and related academic venues. The lack of direct contact info and privacy policies suggests room for improvement in user engagement and compliance. The technical stack is standard for academic sites, with Joomla providing extensibility but requiring maintenance to avoid vulnerabilities.

Security posture

The website uses HTTPS, which is mandatory and a strong baseline. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected, which could expose the site to clickjacking or content injection risks. No forms with sensitive inputs were found, reducing immediate risk. The absence of privacy and cookie policies indicates potential GDPR compliance gaps. No incident response or security contact information is provided, limiting transparency. Overall, the security posture is moderate but could be significantly improved with standard best practices and compliance documentation.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish comprehensive privacy and cookie policies to enhance GDPR and privacy compliance.
  3. Add clear contact information including security incident response contacts.
  4. Regularly update Joomla CMS and all extensions to mitigate vulnerabilities.
  5. Improve accessibility features and SEO metadata for broader reach and compliance.

Technical notes

Notes

The website is built on Joomla CMS with Bootstrap and jQuery libraries, indicating a conventional but somewhat dated technology stack. The site uses FontAwesome for icons and JEvents for event management. Hosting is provided by ACM SIGWEB's own hosting domain. Performance is moderate with no explicit optimization scripts detected. Mobile responsiveness is good due to Bootstrap usage. SEO is basic with meta description and Open Graph tags present but no JSON-LD structured data found. Accessibility is basic with no ARIA landmarks or advanced features detected. The site would benefit from modernization efforts including performance optimization and enhanced accessibility.
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.
