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.

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

Avisi operates primarily in the B2B technology services market, targeting organizations undergoing digital transformation in regulated sectors. Their competitive advantage lies in combining deep technical expertise with sector-specific knowledge and strong security and privacy certifications. The company maintains an active content strategy with blogs, case studies, and whitepapers, supporting thought leadership and client engagement. Their partnership ecosystem includes recognized clients and technology partners, enhancing their market credibility. Avisi's business model focuses on delivering tailored software solutions and strategic advisory services, supported by a medium-sized organizational structure and a 25-year operational history.

Security posture

Avisi demonstrates a robust security posture with enforced HTTPS, comprehensive security headers, and adherence to recognized frameworks such as ISO 27001 and NIS2. The website includes cookie consent mechanisms and privacy policies aligned with GDPR requirements. No exposed sensitive data or vulnerable libraries were detected. However, the absence of a public incident response contact or vulnerability disclosure policy suggests room for improvement in transparency and incident management readiness. Overall, Avisi's security maturity supports its positioning as a trusted partner for sensitive and regulated industries.

Recommendations

  1. Publish a dedicated incident response and vulnerability disclosure page to enhance transparency and trust.
  2. Implement and publicize a security.txt file to facilitate responsible vulnerability reporting.
  3. Enhance data retention policy disclosures to improve privacy compliance clarity.
  4. Regularly audit third-party scripts and tracking tools to minimize privacy risks.
  5. Continue investing in security awareness and compliance to maintain leadership in regulated sectors.

Notes

The website is built on a modern technology stack leveraging HubSpot CMS, JavaScript frameworks, and backend technologies such as Java and Kotlin. It integrates advanced analytics and marketing tools including Google Analytics 4 and HubSpot tracking, with appropriate consent mechanisms. The site is mobile-optimized, fast-loading, and accessible, reflecting good technical implementation practices. Hosting appears to be managed via HubSpot, ensuring reliable uptime and security. Opportunities exist to further enhance technical transparency around data handling and incident response capabilities.
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.
