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

Citus Data is a technology company specializing in distributed PostgreSQL database solutions. Their core offering is the Citus extension, which enables horizontal scaling of Postgres databases through distributed tables and parallel query execution. The company provides both an open source version and a managed cloud service integrated with Microsoft Azure Cosmos DB for PostgreSQL. Positioned as a niche leader in scalable Postgres solutions, Citus Data targets developers and enterprises requiring high-performance, scalable database infrastructure. The website reflects a mature digital presence with professional design, clear navigation, and strong Microsoft branding, indicating a medium-sized enterprise with solid market positioning. Technically, the website leverages modern web technologies including Google Fonts, SVG graphics, JavaScript, Marketo forms for lead capture, and Google reCAPTCHA for bot protection. The hosting and cloud service references suggest Microsoft Azure as the underlying platform. The site is well optimized for mobile devices, SEO, and accessibility, providing a fast and user-friendly experience. From a security perspective, the site enforces HTTPS and includes cookie consent mechanisms aligned with GDPR compliance. However, explicit security headers are not detected, and there is no published security policy or incident response information, which are areas for improvement. The absence of WHOIS data for the domain is unusual but mitigated by the strong Microsoft association and trust signals such as customer testimonials and GitHub presence. Overall, the website presents a trustworthy and professional front for Citus Data's business, with a solid technical foundation and good privacy compliance. Strategic recommendations include enhancing security headers, publishing a security policy, and providing incident response contacts to further strengthen trust and security posture.

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.

Priority findings

1 finding 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.

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

Citus Data operates in the technology sector, focusing on database scalability solutions for Postgres users. Their business model combines open source software with a managed cloud service, leveraging Microsoft's Azure platform. The company targets SaaS providers, enterprises, and developers needing distributed database capabilities. Their market position is strengthened by integration with Microsoft and a strong community presence on GitHub. Revenue streams likely include support, consulting, and managed service subscriptions. The partnership ecosystem includes Microsoft and cloud service providers. Growth indicators include recent product updates supporting Postgres 17 and active community engagement. The company's operations emphasize scalability, performance, and ease of adoption for multi-tenant SaaS, real-time analytics, time series, and microservices architectures.

Security posture

The website demonstrates a moderate to strong security posture with mandatory HTTPS and cookie consent mechanisms. Use of Google reCAPTCHA on forms reduces automated abuse risk. However, the absence of key security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options represents a gap that could expose users to clickjacking or content injection attacks. No security policy or vulnerability disclosure page is published, limiting transparency and incident response readiness. No contact channels for security incidents are provided. No vulnerabilities or exposed sensitive data were detected in the HTML content. Compliance with GDPR is indicated through privacy and cookie policies linked to Microsoft. Overall, the security posture is good but could be improved by adopting additional headers and publishing security documentation.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to enhance protection against common web attacks.
  2. Publish a comprehensive security policy and vulnerability disclosure page to improve transparency and facilitate responsible reporting of security issues.
  3. Provide clear incident response contact information, such as a dedicated security email address, to enable timely communication of security events.
  4. Regularly audit and update third-party libraries and scripts to mitigate risks from vulnerable dependencies.
  5. Enhance trust signals by displaying relevant certifications or compliance attestations if applicable.

Technical notes

Notes

The website is built with modern web standards, using HTML5, CSS3, and JavaScript. It incorporates Google Fonts for typography and SVG for scalable graphics, ensuring crisp visuals across devices. Marketo forms are used for lead capture, integrated with Google reCAPTCHA for spam prevention. The site is mobile responsive and optimized for SEO with appropriate meta tags and Open Graph data. Hosting appears to be on Microsoft Azure infrastructure, consistent with the parent company branding. Performance is fast with preloading of key images and asynchronous script loading. No CMS is explicitly detected, suggesting a custom or static site architecture. Technical risks are minimal, but the lack of explicit security headers and WHOIS data represent areas for improvement to reduce operational risk.
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.
