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

Opus Online OÜ is an established Estonian software development company specializing in custom IT solutions and e-commerce platforms, primarily serving clients in finance, insurance, and pharmaceutical sectors. With over 14 years of experience and more than 120 successful projects, the company positions itself as a reliable partner for startups and large corporations alike. Their key services include bespoke software development, Magento 2 and BigCommerce e-commerce solutions, UX/UI design, and ongoing maintenance and support. The website reflects a professional and consistent brand image with clear navigation and relevant content tailored to their target audience. Technically, the website is built on WordPress 6.8.1, leveraging modern JavaScript frameworks like React and NodeJS for client projects. The use of Magento 2 and BigCommerce platforms for e-commerce solutions indicates a mature technology stack. The site is mobile-optimized and accessible, with good SEO practices implemented. Performance is moderate, with room for optimization. Security posture is solid with HTTPS enforced and secure form handling, but lacks some advanced security headers and published security policies. No vulnerabilities or exposed sensitive data were detected. Privacy compliance is weak due to the absence of privacy and cookie policies and consent mechanisms, which is a notable compliance gap. Contact information is comprehensive and clearly presented, enhancing business credibility. Overall, the website and business demonstrate a strong market position and technical maturity, but should prioritize privacy compliance and enhance security policies to improve trust and regulatory adherence.

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

10 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.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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

      • ASVS V3.4.3

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

Opus Online operates in the technology sector with a focus on software development and e-commerce solutions. Their market positioning is that of a trusted partner with extensive experience in critical IT projects for finance, insurance, and healthcare clients. The business model revolves around providing tailored digital solutions and ongoing support services. Revenue streams likely include project-based development, platform-specific e-commerce implementations, and maintenance contracts. Target customers range from startups to large enterprises requiring scalable and compliant digital products. The company showcases a solid partnership ecosystem through client testimonials and social media presence. Strategic observations include a focus on quality, client-centric processes, and leveraging modern technologies to maintain competitive advantage.

Security posture

The current security maturity level is moderate to good. The website enforces HTTPS and uses secure contact forms with anti-spam features. However, it lacks several recommended security headers such as Content-Security-Policy and X-Frame-Options, which could mitigate certain attack vectors. There is no publicly available security policy or incident response information, and no vulnerability disclosure or security.txt file is present. GDPR compliance is incomplete due to missing privacy and cookie policies. Data protection practices appear sound with no exposed sensitive data. Incident response readiness and security culture indicators are not evident from the website. Overall, the security posture is adequate but could be significantly improved by addressing compliance and policy transparency.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy with explicit consent mechanisms to ensure GDPR compliance.
  2. Implement and configure essential security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options.
  3. Develop and publish an incident response plan and vulnerability disclosure policy, including a security.txt file.
  4. Regularly audit and update third-party plugins and scripts to mitigate potential vulnerabilities.
  5. Enhance transparency and trust by adding data retention policies and appointing a Data Protection Officer contact.

Technical notes

Notes

The website is built on a modern and widely supported CMS platform, WordPress 6.8.1, combined with JavaScript frameworks like React and NodeJS for client-facing projects. The use of Magento 2 and BigCommerce platforms for e-commerce solutions indicates a robust and scalable infrastructure. The site includes responsive design and accessibility considerations, contributing to a positive user experience. Performance is moderate, suggesting potential for optimization in loading times and resource management. The technical debt appears low, but the absence of some security headers and privacy compliance features indicates areas for modernization. Overall, the technical infrastructure supports the business goals effectively but should evolve to meet higher security and compliance 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.
