0–100, higher is better. How it is calculated

FlexApp is a technology startup founded in 2025, offering an AI-powered platform that generates production-ready React Native mobile app code from user-described app ideas. Positioned as a no-code alternative for mobile app development, it targets developers, entrepreneurs, and businesses seeking rapid app creation. The website is professionally designed with modern UI/UX and good mobile optimization, reflecting a mature digital presence for a young company. The technical infrastructure leverages Next.js, React, Expo, and integrates analytics tools like Google Analytics and PostHog, hosted behind Cloudflare DNS services. Security posture is solid with HTTPS and domain transfer protection, though DNSSEC is not enabled and security headers are not explicitly detected. Privacy compliance is basic with privacy and terms pages present but lacking cookie consent mechanisms. Overall, the site demonstrates a good balance of business credibility and technical sophistication, suitable for its market niche.

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. 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';…

  2. GDPR outside view

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

    • 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

    • 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

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

FlexApp operates in the competitive AI-driven no-code mobile app builder market, differentiating itself by focusing on AI-generated React Native code. Its SaaS business model likely includes subscription plans, as indicated by a pricing page. The company leverages social media presence on Twitter and LinkedIn to engage its audience. The use of privacy protection in WHOIS is typical for startups protecting early-stage identity. The absence of phone contact suggests a digital-first customer support approach. The platform's integration with modern frameworks and analytics indicates a growth-oriented and data-driven strategy. No partnerships or subsidiaries were identified, suggesting an independent startup status.

Security posture

The website enforces HTTPS and uses clientTransferProhibited status to prevent unauthorized domain transfers, which are positive security indicators. However, the lack of DNSSEC and missing security headers such as Content-Security-Policy or X-Frame-Options represent areas for improvement. No explicit security or incident response policies are published, which may impact trust for security-conscious users. The absence of cookie consent mechanisms could pose GDPR compliance risks. No vulnerabilities or exposed sensitive data were detected in the HTML content. Overall, the security posture is moderate but could be enhanced with additional best practices and transparency.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS security and integrity.
  2. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Add a cookie consent banner or mechanism to comply with GDPR and enhance privacy transparency.
  4. Publish a dedicated security policy and incident response contact information to improve trust and compliance.
  5. Regularly audit third-party scripts and analytics tools to minimize privacy risks and optimize performance.

Technical notes

Notes

The website is built on a modern React and Next.js stack, optimized for performance and mobile responsiveness. It uses Clerk.js for authentication and PostHog for analytics, indicating a focus on user management and behavioral insights. Hosting appears to be via a CDN and possibly serverless platforms, ensuring fast load times. The site includes well-structured meta tags and Open Graph data for SEO and social sharing. No CMS is detected, suggesting a custom or headless architecture. The technical implementation is robust with minor gaps in security headers and DNS configuration. The site’s design and UX are polished, supporting a professional brand image.
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.
