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

Gitter is a developer-focused chat and networking platform operated by New Vector Ltd, leveraging the Matrix protocol for secure, decentralized communication. The platform targets developer communities and open source projects, offering messaging, content discovery, and community management services. It is trusted by major technology companies such as Airbnb, AWS, Google, and Microsoft, indicating a strong market position within the technology sector. The website content is professional and well-branded, with clear messaging about its services and integration with Matrix clients like Element. Technically, the website uses modern web technologies including the Astro framework and Cloudflare DNS services. The platform supports web and native Matrix clients, emphasizing interoperability and security through end-to-end encryption. Performance and mobile optimization are good, though accessibility and SEO features are basic. No CMS or analytics tools are explicitly detected in the provided content. From a security perspective, the site enforces HTTPS and promotes encrypted messaging via Matrix. However, it lacks explicit security headers, published security policies, and incident response contacts, which are recommended for improving security posture and transparency. No vulnerabilities or exposed sensitive data were detected in the analysis. Privacy compliance is weak due to the absence of privacy and cookie policies, which should be addressed to meet GDPR and other regulations. Overall, Gitter presents a trustworthy and professional platform with solid technical foundations and business credibility. Strategic improvements in privacy disclosures, security policy publication, and contact information would enhance compliance and user trust, supporting its continued growth and market presence.

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

7 findings rated critical or high. Fix these first.

  1. 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';…

  2. 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

    • 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

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

Gitter operates as a platform service provider in the technology sector, focusing on developer and open source communities. Its business model centers on providing a chat and networking environment built on the Matrix protocol, enabling secure and decentralized communication. The presence of high-profile clients and community testimonials underscores its competitive advantage and market acceptance. The company, New Vector Ltd, maintains the platform with a medium-sized operational scale. Partnerships with Matrix.org and Element.io strengthen its ecosystem and technical capabilities. Revenue streams likely include enterprise licensing and service offerings related to the platform. Growth indicators include recent migration to Matrix and active community engagement. The absence of direct contact information and privacy policies suggests areas for operational maturity enhancement.

Security posture

Gitter demonstrates a moderate to strong security posture with HTTPS enforced and use of end-to-end encryption via Matrix. The platform benefits from decentralized communication protocols enhancing security and privacy. However, the lack of published security policies, incident response contacts, and security headers reduces transparency and may hinder rapid incident handling. No exposed sensitive data or vulnerable libraries were identified, indicating good internal security hygiene. Compliance with GDPR and other privacy regulations is not clearly demonstrated due to missing privacy and cookie policies. The security culture appears focused on technical security but could improve in policy communication and user trust mechanisms.

Recommendations

  1. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  2. Implement and disclose security headers such as Content Security Policy (CSP), HSTS, and X-Frame-Options.
  3. Provide clear contact information for security incidents, including a dedicated security or abuse email address.
  4. Add a vulnerability disclosure policy or security.txt file to facilitate responsible reporting.
  5. Enhance accessibility and SEO features to improve user experience and discoverability.

Technical notes

Notes

The website is built using the Astro framework with JavaScript modules for dynamic UI elements. It leverages Cloudflare for DNS and likely CDN services, contributing to good performance and security. The platform integrates with the Matrix protocol, supporting decentralized and encrypted messaging. The site is mobile-optimized and has a clean, professional design. However, it lacks explicit analytics or tracking scripts, which may limit marketing insights but improves privacy. The absence of CMS indications suggests a custom or static site generation approach. Technical debt appears low, but opportunities exist to enhance accessibility and SEO. Overall, the technical infrastructure supports a reliable and secure user experience aligned with the platform's community-focused mission.
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.
