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

ERA a.s. is a globally recognized leader in next-generation surveillance and flight tracking solutions, specializing in multilateration and ADS-B technologies. The company serves a specialized market including air traffic management authorities, military and security agencies, and aviation industry stakeholders. With over 160 installations across 70 countries and 5 continents, ERA holds a strong market position supported by decades of tradition and experience. Their business model focuses on providing mission-critical surveillance systems and related services in a B2B context. Technically, the website demonstrates a mature digital infrastructure using modern web technologies such as HTML5, CSS3, JavaScript, and third-party libraries like Google Tag Manager and Picturefill for responsive images. The site is mobile-optimized and performs moderately well, with good SEO and basic accessibility features. However, there is room for improvement in security headers and accessibility compliance. From a security perspective, ERA's website enforces HTTPS and uses secure form submission methods, with no visible vulnerabilities or exposed sensitive data. The presence of ISO 27001 certification and partnerships with reputable companies like Airbus enhance trust. However, the absence of explicit security headers and incident response information suggests areas for enhancement. Privacy compliance is strong, with a comprehensive privacy policy and cookie consent mechanism aligned with GDPR requirements. Overall, ERA's website reflects a professional, trustworthy, and well-maintained digital presence consistent with its industry standing. The lack of public WHOIS data due to privacy protection is justified given the company's international operations. Strategic recommendations include enhancing security headers, publishing incident response and vulnerability disclosure policies, and improving accessibility to further strengthen the security posture and user trust.

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

5 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • 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

  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.

    • High

      High-Risk Service Exposed: FTP

      Port 21 (FTP) is publicly accessible - FTP - Often unencrypted file transfer

      What to do: Consider restricting access to FTP or implementing strong authentication

      • 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. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

ERA a.s. operates in the specialized aviation surveillance and reconnaissance sector, targeting government agencies, military, and civil aviation authorities. Their competitive advantage lies in their advanced multilateration and ADS-B technologies, extensive global deployment, and longstanding industry experience. Revenue streams likely derive from system sales, implementation, maintenance, and consulting services. The company actively engages in partnerships, exemplified by agreements with Airbus, and maintains a visible presence through press releases and industry events. Growth indicators include recent contracts and participation in NATO-related workshops. ERA's ecosystem includes collaborations with technology providers and defense industry stakeholders, positioning it as a key player in air traffic management and military surveillance markets.

Security posture

ERA's security maturity is moderate to high, with enforced HTTPS, secure form handling, and no apparent exposure of sensitive data. The ISO 27001 certification indicates a formalized information security management system. However, the website lacks several security headers that could mitigate common web threats. There is no public incident response or vulnerability disclosure information, which could hinder rapid response to security incidents. GDPR compliance is evident through privacy and cookie policies with consent mechanisms. The security culture appears professional but could benefit from enhanced transparency and proactive communication channels for security issues. No critical vulnerabilities or compliance gaps were detected in the website content.

Recommendations

  1. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish an incident response policy and provide dedicated contact channels for security incidents to improve transparency and readiness.
  3. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Enhance website accessibility features to meet recognized standards and improve user experience for all visitors.
  5. Conduct regular audits of third-party scripts and dependencies to identify and mitigate potential vulnerabilities.

Technical notes

Notes

The website employs a modern and responsive design using HTML5, CSS3, and JavaScript with libraries such as Slick Carousel and Picturefill for enhanced media handling. Google Tag Manager is used for analytics and marketing tracking. The site uses a POST method for search forms, indicating secure data submission practices. Performance is moderate with room for optimization. No CMS or hosting provider details are explicitly detected. Accessibility is basic but could be improved. SEO practices are good with proper meta tags and Open Graph data. The lack of security headers is a technical gap. Overall, the technical infrastructure supports a professional and functional user experience aligned with the company's business needs.
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.
