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

2 findings rated critical or high. Fix these first.

  1. 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
    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

Opera holds a strong market position as a major browser vendor with a large user base and innovative features such as built-in VPN, ad blocker, and AI integration. The business model centers on free software distribution supplemented by affiliate programs and additional services. The company maintains a global presence with teams across Europe, Africa, and Asia. Partnerships and subsidiaries include official add-ons and authentication services. Growth is supported by continuous innovation in browser technology and expansion into gaming and AI. The website's comprehensive policies and social media presence reinforce credibility and user trust.

Security posture

The website demonstrates a good security maturity level with HTTPS, cookie consent, and privacy policies aligned with GDPR. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers and a published security.txt file limits transparency in vulnerability disclosure and incident response readiness. The lack of direct security contact channels is a minor compliance gap. Overall, the security culture appears proactive but could benefit from enhanced communication and technical controls.

Recommendations

  1. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to strengthen browser security.
  2. Publish a security.txt file to facilitate responsible vulnerability disclosure and improve transparency.
  3. Provide explicit incident response contact information on the security page or footer.
  4. Regularly audit third-party scripts and analytics tools to mitigate supply chain risks.
  5. Enhance accessibility features to improve inclusivity and compliance with standards.

The website uses a modern tech stack including JavaScript, Google Tag Manager, Google Analytics, and Snowplow Analytics, ensuring robust tracking and marketing capabilities. The site is well-optimized for performance and mobile responsiveness, with comprehensive meta tags and SEO best practices. No CMS was explicitly detected, suggesting a custom or proprietary platform. Hosting details are not disclosed but content delivery is via a CDN domain. The site shows no technical debt or broken elements, indicating good maintenance and modernization efforts. Opportunities exist to improve security headers and accessibility compliance.
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.
