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

The website cert.rs represents the National CERT of the Republic of Serbia, a government-affiliated entity responsible for cybersecurity incident prevention, coordination, and response at the national level. It operates under the Regulatory Agency for Electronic Communications and Postal Services (RATEL). The site provides security advisories, incident reporting mechanisms, and public awareness content primarily in Serbian with multilingual support. The domain is well-established since 2014 and uses DNSSEC and HTTPS to ensure secure communications. Technically, the website employs modern frontend technologies including Bootstrap 5, jQuery, and Font Awesome, with a custom CMS backend inferred from asset paths. The site is mobile responsive and optimized for usability, though accessibility features are basic. No major performance issues were detected. Security posture is strong with HTTPS and DNSSEC enabled, but lacks some HTTP security headers and a published security.txt file. From a security perspective, the site demonstrates good practices such as incident reporting and public advisories but could improve by publishing explicit vulnerability disclosure policies and enhancing security headers. No vulnerabilities or suspicious content were detected. Privacy compliance is robust with clear privacy and cookie policies and consent mechanisms. Overall, cert.rs is a credible, professional, and trustworthy national cybersecurity resource with a solid technical foundation and good security hygiene. Strategic improvements in security headers and disclosure policies would further enhance its 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.

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 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 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

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 National CERT of Serbia holds a strong market position as the authoritative cybersecurity coordination body for the country, operating under RATEL. Its business model is regulatory and service-oriented, focusing on incident response, public education, and national cybersecurity coordination. The target audience includes government entities, private sector ICT organizations, and the general public. The organization benefits from partnerships with international CERT associations and academic institutions, enhancing its credibility and operational effectiveness. The website content and structure reflect a medium-sized government entity with consistent branding and a clear mission. Revenue streams are likely government-funded, with no commercial advertising or affiliate programs present.

Security posture

The security maturity of cert.rs is good, with HTTPS enforced and DNSSEC enabled, indicating strong domain and transport security. The site lacks some advanced HTTP security headers, which could mitigate risks such as clickjacking and cross-site scripting. No exposed sensitive data or vulnerable libraries were detected in the frontend. Incident response mechanisms are in place with a dedicated incident reporting page. GDPR compliance is evident through privacy and cookie policies with consent banners. However, the absence of a security.txt file and explicit vulnerability disclosure policy is a gap. Overall, the site demonstrates a mature security culture appropriate for a national CERT but can improve in transparency and header security.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  2. Publish a security.txt file at the root domain to facilitate vulnerability disclosure and improve transparency.
  3. Enhance accessibility features to meet WCAG standards for broader inclusivity.
  4. Regularly audit and update third-party libraries to mitigate potential vulnerabilities.
  5. Maintain and update privacy and cookie policies to reflect evolving regulations and best practices.

Technical notes

Notes

The website uses a modern frontend stack with Bootstrap 5 and jQuery 3.6.1, ensuring responsive design and interactive features. The presence of a custom CMS is inferred from asset paths, suggesting tailored content management. Performance is moderate with CDN usage for Bootstrap and Popper.js, but no explicit hosting provider was identified. SEO is supported by proper meta tags and Open Graph data, enhancing social sharing and search visibility. The site is mobile optimized with a responsive navbar and accessible search functionality. Technical debt appears low, but improvements in accessibility and security headers are recommended to future-proof the platform.
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.
