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

Opera Norway AS operates the official website for the Opera web browser, a well-established and innovative browser offering enhanced privacy, security, and unique features such as free VPN, built-in messengers, and AI integration. The company targets a broad audience including general internet users and gamers, positioning itself as a forward-thinking technology provider in the browser market. The website reflects a mature digital presence with comprehensive content, professional design, and clear navigation. Technically, the website employs modern web technologies including JavaScript, SVG, and JSON-LD structured data, and integrates analytics and marketing tools like Google Analytics and Google Tag Manager. The site is mobile-optimized and performs well, with good SEO and accessibility practices. Security-wise, the site uses HTTPS and provides detailed privacy and cookie policies, though explicit security headers and incident response contacts could be improved. Overall, the security posture is strong with no visible vulnerabilities or exposed sensitive data. The WHOIS data is incomplete or protected, which is common for large companies, but the website's professionalism and trust signals support its legitimacy. Strategic recommendations include enhancing security headers, publishing a vulnerability disclosure policy, and providing incident response contacts to further strengthen trust and 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

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 Norway AS holds a significant position in the technology sector as a browser developer with a large user base and innovative product offerings. Their business model revolves around software development and distribution, supplemented by affiliate programs and partnerships. The company maintains a global presence with teams across multiple continents. Their ecosystem includes gaming-focused browsers and AI-enhanced browsing experiences, indicating a focus on future technologies and user engagement. The website's integration with multiple social media platforms and marketing tools reflects an active digital marketing strategy. Growth indicators include continuous product updates and new feature launches such as Opera Air and Opera One. Partnerships with app stores and affiliate programs expand their reach, while their investor and job portals indicate organizational maturity and transparency.

Security posture

The website demonstrates a mature security posture with enforced HTTPS, comprehensive privacy and cookie policies, and a cookie consent mechanism. No exposed sensitive data or vulnerable libraries were detected in the HTML content. However, the absence of explicit security headers like Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options suggests room for improvement. The lack of publicly available incident response contacts or a vulnerability disclosure policy limits transparency in security incident handling. Compliance with GDPR is indicated by privacy policy content and cookie consent features. Overall, the site is secure for users but could enhance trust by publishing more detailed security practices and contact information.

Recommendations

  1. Implement and publish explicit security headers such as CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Create and make publicly available a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  3. Provide clear incident response contact information, such as a dedicated security email address, to improve transparency and responsiveness.
  4. Regularly audit and update third-party scripts and libraries to ensure no vulnerabilities are introduced.
  5. Enhance user trust by including certifications or compliance badges related to security and privacy standards.

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.
