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. Network security

    Services reachable from the internet are the first thing attackers probe. Anything open that does not need to be should be closed.

    • Critical

      Critical Service Exposed: MySQL

      Port 3306 (MySQL) is publicly accessible - MySQL - Database server

      What to do: Immediately restrict access to MySQL using firewall or VPN

      • NIS2 21(2)(e)
      • IR 2024/2690 6.7.2(f): Implementing Regulation (EU) 2024/2690, Annex point 6.7.2(f): Network security
      • NIST CM-7: NIST SP 800-53 Rev. 5 CM-7: Least Functionality
      • NIST SC-7: NIST SP 800-53 Rev. 5 SC-7: Boundary Protection

  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

      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';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

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.

Breach exposure

Dark web exposure

Add-on

Leaked records that mention apper.ch, from OffSeq Breach.

No leaked records found

Breach holds no records for apper.ch 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

Apper operates in the technology sector, focusing on app development and consulting services. Their business model is service-oriented, targeting small to medium enterprises and organizations requiring custom app solutions. The company leverages modern technologies and maintains a professional online presence with social media channels on LinkedIn and Instagram. The portfolio showcases diverse projects, indicating a broad capability in various app domains including legaltech, insurancetech, and social media. The absence of direct contact emails or phone numbers suggests a preference for managed contact via forms and scheduling tools like Calendly. No parent or subsidiary companies are identified, indicating an independent operation. The company demonstrates consistent branding and good content quality, supporting a positive market position.

Security posture

The website enforces HTTPS, ensuring encrypted communications. However, no explicit security headers such as Content Security Policy or X-Frame-Options were detected in the HTML content, which could enhance protection against common web attacks. The presence of WordPress and associated plugins necessitates regular updates to mitigate vulnerabilities. No exposed sensitive data or vulnerable libraries were identified in the source. The site lacks publicly available security policies or incident response contacts, which could be improved to enhance trust and readiness. Google Analytics is present but not configured, reducing privacy risks but also limiting analytics insights. Overall, the security posture is moderate with good encryption but opportunities for strengthening header policies and transparency.

Recommendations

  1. Implement and configure security headers including CSP, HSTS, and X-Frame-Options to improve web security.
  2. Publish explicit security and incident response policies including contact channels for reporting issues.
  3. Regularly audit and update WordPress plugins and themes to prevent vulnerabilities.
  4. Configure or remove unused analytics plugins to align with privacy best practices.
  5. Consider adding a security.txt file and vulnerability disclosure policy to foster responsible reporting.

Notes

The website is built on a WordPress CMS platform using modern plugins such as Yoast SEO and WPBakery Page Builder, ensuring ease of content management and SEO optimization. The tech stack includes jQuery, Swiper.js for sliders, SmartMenus for navigation, and Isotope for layout management, indicating a rich interactive user experience. Google Fonts are used for typography, specifically the Ubuntu font family. The site loads with moderate performance, with some heavy CSS and JavaScript assets but optimized with caching and minification. Mobile optimization is good with responsive design and accessible navigation. The site uses a Calendly widget for scheduling inquiries, integrating third-party services smoothly. Overall, the technical infrastructure is solid with room for performance tuning and enhanced accessibility features.
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.
