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

7 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 Cookie Policy found

      GDPR requires clear information about cookie usage

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

  2. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  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 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

      Prevents clickjacking attacks

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

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.

Dark web exposure

Add-on

Leaked records that mention appvizer.de, from OffSeq Breach.

No leaked records found

Breach holds no records for appvizer.de right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Appvizer occupies a niche as a trusted software comparison medium, targeting professionals and companies looking for tailored SaaS solutions. Its business model centers on providing expert content, user reviews, and AI-driven recommendations, likely monetized through partnerships and lead generation with software vendors. The platform supports multiple languages, indicating an international expansion strategy. The presence of verified user reviews and structured data enhances credibility. The company operates in the technology sector with a medium-sized footprint, focusing on digital transformation and software procurement. Its ecosystem includes social media engagement and integration with analytics and marketing tools, supporting growth and user acquisition.

Security posture

The website demonstrates a good security baseline with enforced HTTPS and secure input forms. However, the absence of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options reduces defense-in-depth. No public security or incident response policies were found, which could impact transparency and readiness. There is no evidence of vulnerability disclosure programs or security certifications. No exposed sensitive data or vulnerable libraries were detected in the HTML content. Overall, the security posture is adequate but could be improved by adopting additional security headers and publishing formal security policies.

Recommendations

  1. Implement and enforce security headers including CSP, HSTS, and X-Frame-Options to enhance protection against common web attacks.
  2. Publish a dedicated security policy and incident response plan to improve transparency and user trust.
  3. Establish a vulnerability disclosure program or security.txt file to encourage responsible reporting of security issues.
  4. Consider adding direct contact information for security or abuse reporting to facilitate incident handling.
  5. Regularly audit third-party scripts and dependencies to ensure no vulnerable libraries are included.

Technical notes

Notes

The website is built using React 18.3.0 with modern JavaScript modules, indicating a contemporary tech stack. It uses Google Tag Manager and Microsoft Clarity for analytics and user behavior tracking. Hosting is provided by OVH, a reputable European provider. The site is mobile optimized with responsive design and good accessibility features. SEO is supported by comprehensive meta tags, Open Graph data, and JSON-LD structured data describing the organization and website. Performance is moderate, likely due to rich content and external scripts. There is no detected CMS, suggesting a custom or headless architecture. Opportunities exist to improve performance by optimizing third-party scripts and enhancing security headers.
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.
