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

Nette.org is the official website for the Nette Framework, a mature and secure PHP framework developed and maintained since 2008 by David Grudl. The framework is highly regarded in the PHP community, ranked as the third most popular PHP framework worldwide. The website serves PHP developers and web application creators by providing comprehensive documentation, community support, and access to a suite of standalone components that emphasize security, productivity, and best practices. The business model is primarily open source with sponsorship and donation support from a variety of partners and community members. Technically, the website is well-constructed using modern web technologies including PHP 8, JavaScript ES modules, and CSS, hosted on CESNET infrastructure. It demonstrates good performance, mobile optimization, and accessibility. SEO is well implemented with proper meta tags and Open Graph data. Analytics are implemented via Google Tag Manager with moderate user tracking. The site lacks a visible cookie consent mechanism and explicit privacy policy, which could be improved for GDPR compliance. From a security perspective, the domain is secured with HTTPS and domain transfer/update protections. The framework itself prioritizes security with protections against common web vulnerabilities such as XSS and CSRF. However, the website could enhance its security posture by enabling DNSSEC, adding security headers, and publishing clear security and incident response policies. No vulnerabilities or suspicious content were detected. Overall, Nette.org presents a professional, trustworthy, and technically sound presence for a well-established open source PHP framework. Strategic recommendations include improving privacy compliance, enhancing security headers, and publishing incident response and vulnerability disclosure policies to further strengthen trust and compliance.

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 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 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

    • 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

    • High

      Third-party services without privacy policy

      Detected services: Google Analytics, Twitter

      What to do: Document all third-party data sharing in your privacy policy

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

Business profile

Nette Framework holds a strong market position as a top PHP framework with over 18 years of development history. Its competitive advantages include a focus on security, productivity, and best practices, supported by a mature codebase and active community. Revenue streams appear to be primarily through sponsorships and donations, with a broad target audience of PHP developers and companies building web applications. The partnership ecosystem includes multiple platinum and gold sponsors from diverse technology and service sectors, indicating healthy community and business engagement. The open source nature and comprehensive documentation support growth and adoption. Strategic observations suggest opportunities to expand compliance and security transparency to appeal to enterprise users and regulated industries.

Security posture

The website and underlying framework demonstrate a mature security posture with HTTPS enforced, domain transfer/update protections, and a design philosophy prioritizing security. The framework addresses common web vulnerabilities and has passed multiple security audits. However, the website itself lacks explicit security headers (e.g., CSP, HSTS) and does not publish incident response or vulnerability disclosure policies, which are important for transparency and trust. No exposed sensitive data or vulnerable libraries were detected. GDPR compliance is partial due to missing cookie consent and privacy policy details. Overall, the security maturity is good but could be improved with additional policies and technical controls.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement and publish a comprehensive privacy policy and cookie consent mechanism to improve GDPR compliance.
  3. Add security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options to harden the website against common attacks.
  4. Publish an incident response policy and vulnerability disclosure program to increase transparency and community trust.
  5. Consider adding visible contact information or dedicated security contact channels for reporting security issues.

Technical notes

Notes

The website uses a modern technology stack including PHP 8, ES module JavaScript, and CSS with module preloading for performance. It is hosted on CESNET infrastructure, indicating reliable hosting. The site is mobile optimized and accessible with good SEO practices including Open Graph and Twitter card metadata. Google Tag Manager is used for analytics with anonymized IP and client-side hashing for privacy. The domain is registered with Tucows Domains Inc. since 2008, consistent with the business age. No CMS detected, indicating a custom or framework-based site. Performance is fast with no broken elements detected. Technical risks are low but could be further mitigated by enabling DNSSEC and adding 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.
