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

3 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

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

    • 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

  2. 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.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

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

Fortnox operates primarily in the finance sector, offering modular and integrated business solutions that cater to a wide range of customer segments including direct business customers and accounting agencies. Their business model revolves around subscription-based SaaS offerings with additional financing services. The company maintains a strong partnership ecosystem, including integration partners and a corporate group presence via fortnoxgroup.com. Growth indicators include extensive product offerings, a large customer base, and active content marketing through blogs and knowledge bases. Strategic observations highlight their focus on automation, customer collaboration, and scalable solutions.

Security posture

The website exhibits a mature security posture with HTTPS enforced and multiple security headers likely in place. Consent management is handled via Piwik PRO, ensuring GDPR compliance. Forms are secured with required fields and no sensitive data is exposed in the HTML. However, the absence of a public incident response contact or security.txt file suggests room for improvement in vulnerability disclosure and incident handling transparency. No vulnerabilities or security issues were detected in the provided content.

Recommendations

  1. Publish explicit incident response and abuse contact information to improve transparency and readiness.
  2. Implement and publish a security.txt file to facilitate responsible vulnerability disclosure.
  3. Regularly audit and update third-party scripts and dependencies to mitigate potential vulnerabilities.
  4. Enhance user awareness by providing clear security and privacy information accessible from the main site.
  5. Continue to monitor and improve consent management to align with evolving privacy regulations.

Technical notes

Notes

Fortnox's website is built on a modern tech stack including Next.js and React, supported by a headless CMS (Storyblok). The site is optimized for performance and mobile responsiveness, with good SEO and accessibility practices. Integration of analytics and consent management via Piwik PRO is well implemented. The use of Upsales forms indicates a structured approach to lead capture and customer interaction. Hosting details are not explicit but the site loads quickly and securely. Technical risks are minimal, with opportunities for further modernization in security transparency and incident response.
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.
