Security score

73/100

Risk levelMedium

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

Sardina Systems is a technology company specializing in automated cloud-native infrastructure solutions leveraging OpenStack, Kubernetes, and Ceph. Their platform targets businesses seeking scalable, stable, and cost-effective cloud deployments. The website presents a professional and consistent brand image with good content quality and SEO optimization. Technically, the site is built on WordPress with modern cloud technologies referenced, and it employs HTTPS with strong SSL configuration. However, the absence of WHOIS registration data raises concerns about domain legitimacy. Security posture is moderate with HTTPS but lacks security headers and explicit privacy or cookie policies. Overall, the site is functional and professional but requires improvements in compliance and security transparency to enhance trust and reduce risk.

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

3 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 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 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. 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.

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

The company operates in the technology sector, focusing on cloud infrastructure automation for enterprise clients. Their business model centers on delivering OpenStack-based cloud solutions integrated with Kubernetes orchestration and Ceph storage. The target audience includes businesses needing scalable cloud platforms without hidden costs. Sardina Systems maintains an active social media presence, which supports marketing and customer engagement. The lack of detailed company registration and domain ownership information limits full business credibility assessment. No partnerships or subsidiaries were identified from the data.

Security posture

The website enforces HTTPS and uses SSL certificates properly, which is a strong security baseline. However, the lack of security headers such as Content-Security-Policy, X-Frame-Options, and others reduces defense-in-depth. No privacy or cookie policies were found, indicating potential GDPR compliance gaps. There is no evidence of a vulnerability disclosure program or incident response contacts, which limits transparency and readiness for security incidents. Tracking scripts from LinkedIn and Mailchimp are present, but data collection practices and retention policies are not disclosed. Overall, the security posture is moderate but requires enhancements in policy transparency and technical controls.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to ensure GDPR compliance.
  2. Add security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to improve security posture.
  3. Establish and disclose a vulnerability disclosure program and incident response contact information.
  4. Verify and update WHOIS domain registration information to ensure domain legitimacy and trust.
  5. Enhance transparency around data collection, tracking, and retention policies to improve user trust.

Technical notes

Notes

The website is built on WordPress CMS with the All in One SEO plugin, indicating a focus on SEO best practices. It references advanced cloud technologies like OpenStack, Kubernetes, and Ceph, suggesting the company’s technical expertise. Performance is moderate with good mobile optimization and basic accessibility features. External scripts include LinkedIn Insight and Mailchimp for marketing and analytics. The site lacks advanced security headers and detailed technical metadata about hosting or infrastructure. There is an opportunity to modernize security configurations and improve compliance-related technical implementations.
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.
