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

Opera AG is a Swiss-based company specializing in event technology services, supporting events such as symposia, congresses, sports events, and Special Olympics. The company presents itself as a professional and established service provider in the regional event technology market. Their website is well-structured, primarily in German, and targets event organizers and companies requiring technical event support. The business model focuses on providing technical event solutions and project support. Technically, the website uses a moderate technology stack including jQuery, Fancybox, GSAP, and Google Analytics with IP anonymization. However, some libraries are outdated, and mobile optimization is basic. Security posture is moderate with HTTPS implied but no visible security headers or advanced security policies. Privacy compliance is minimal with a privacy policy present but no cookie consent mechanism. Contact information is clearly provided, enhancing business credibility. Overall, the website is professional but could improve in security and privacy compliance.

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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • 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
    • 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

  2. 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

  3. 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 · found on this site
  • 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

Opera AG operates in the niche event technology sector within Switzerland, serving clients who organize events requiring technical support. The company leverages social media channels like Facebook and Instagram to engage with its audience. The business appears small-sized with no parent or subsidiary companies indicated. The website content and news updates suggest active engagement in notable events, reinforcing market presence. Revenue streams likely derive from event technology services and project management. The company maintains a consistent brand image and professional online presence, which supports trust and client acquisition. However, the lack of detailed business registrations or certifications on the site limits deeper business intelligence insights.

Security posture

The website employs HTTPS and Google Analytics with IP anonymization, indicating basic security awareness. However, the absence of security headers such as Content Security Policy, X-Frame-Options, and HSTS reduces the overall security posture. No incident response or security policy information is published, and no vulnerability disclosure or security.txt files are present. The use of older JavaScript libraries may expose the site to known vulnerabilities. Privacy compliance is limited, lacking cookie consent mechanisms and GDPR explicit indicators. Overall, the security maturity is moderate but requires improvements to meet higher compliance and security standards.

Recommendations

  1. Implement a cookie consent banner to comply with GDPR and improve privacy transparency.
  2. Add and configure security headers including CSP, HSTS, X-Frame-Options, and X-XSS-Protection.
  3. Update JavaScript libraries to latest stable versions to mitigate known vulnerabilities.
  4. Publish a security policy and incident response contact information to enhance trust and preparedness.
  5. Improve mobile responsiveness and accessibility to enhance user experience and SEO.

Technical notes

Notes

The website uses a combination of legacy and modern JavaScript libraries such as jQuery 2.1.4 and GSAP plugins. Google Analytics is integrated with IP anonymization and an opt-out function, showing some privacy consideration. The site uses cycle2 for slideshows and Fancybox for lightbox effects. No CMS or hosting provider information is evident. Performance is moderate with multiple large background images and slideshows which may impact load times. Mobile optimization is basic, with viewport meta tags present but no advanced responsive design frameworks detected. SEO is basic with meta keywords and description tags but no structured data or Open Graph tags. Accessibility features are minimal, relying on standard HTML semantics without ARIA roles or landmarks. Overall, the technical implementation is functional but could benefit from modernization and optimization.
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.
