fiskaly GmbH is a technology company specializing in cloud-based fiscalization solutions tailored for European markets including Germany, Austria, Spain, Italy, and France. Their services focus on enabling retailers and POS providers to comply with complex fiscal regulations through APIs and cloud services. fiskaly holds a strong market position as a leading provider of cloud TSS solutions in Germany and is expanding its footprint across Europe. The website demonstrates a professional, well-branded presence with comprehensive content, customer testimonials, and partner endorsements. Technically, the website is built on a modern Next.js framework hosted on Netlify, leveraging React and various marketing and analytics tools such as Google Tag Manager and Visual Website Optimizer. The site is mobile-optimized and accessible, with good SEO practices. However, a critical security issue is present due to an invalid or missing SSL certificate and disabled TLS protocols, which significantly impacts the security posture. Security-wise, fiskaly implements several best practices including HSTS and security headers, and holds ISO 27001 certification, indicating a mature security framework. Despite this, the lack of a valid SSL certificate and TLS support is a major vulnerability that must be addressed urgently to protect user data and maintain trust. Overall, fiskaly presents a credible and professional business with strong compliance and technical capabilities but must remediate critical SSL/TLS issues to ensure secure and trustworthy operations online.

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

6 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 Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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

  3. 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 X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

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

fiskaly operates a B2B SaaS business model focused on fiscal compliance solutions for retailers and POS providers. Their competitive advantage lies in cloud-based, API-first fiscalization services that simplify compliance with country-specific regulations. The company targets medium to large businesses requiring secure and legally compliant transaction recording. fiskaly's partnership ecosystem includes major players like Oracle and Uber, enhancing credibility. The company actively participates in industry events such as EuroCIS, signaling growth and market engagement. Their content strategy includes detailed blogs, customer success stories, and developer resources, supporting customer acquisition and retention.

Security posture

The security maturity of fiskaly is mixed. The company holds ISO 27001 certification and implements key security headers and policies, demonstrating a commitment to security best practices. However, the website's SSL configuration is critically flawed with an invalid or missing certificate and no enabled TLS protocols, exposing users to potential interception and undermining trust. No incident response contacts or vulnerability disclosure policies were found, indicating room for improvement in transparency and readiness. Privacy compliance is strong with GDPR-aligned policies and consent mechanisms. Overall, fiskaly should prioritize SSL/TLS remediation and consider publishing incident response and vulnerability disclosure information to enhance security posture.

Recommendations

  1. Immediately fix the SSL certificate to ensure it is valid, trusted, and properly configured.
  2. Enable modern TLS protocols (TLS 1.2 and TLS 1.3) to secure data in transit.
  3. Implement OCSP stapling to improve SSL performance and security.
  4. Expand security documentation to include incident response contacts and vulnerability disclosure policies.
  5. Maintain and promote ISO 27001 certification and other security best practices to reinforce trust.
Technical notes

Notes

The website is built on a modern, scalable tech stack using Next.js and React, hosted on Netlify, which supports fast deployment and good performance. The site is mobile-optimized and accessible with good SEO metadata and structured content. However, performance metrics were not available, limiting assessment of load speed. The use of marketing and analytics tools is balanced with privacy-conscious consent defaults. The critical technical risk is the SSL/TLS misconfiguration, which undermines the otherwise solid infrastructure. Addressing this will significantly improve the technical robustness and user trust.
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.
