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

Symfony SAS operates the symfony.com website, offering a high-performance PHP framework and a set of reusable PHP packages for web development. The company is positioned as a leading technology provider in the PHP ecosystem, serving developers and enterprises with open-source software complemented by professional services such as training, certification, quality assurance tools, and hosting solutions. Their market presence is reinforced by partnerships with Platform.sh for hosting and Blackfire for performance profiling, alongside a strong community and educational resources. Technically, the website employs modern web technologies including Symfony framework, Bootstrap, Stimulus, and various JavaScript libraries, hosted on Cloudflare infrastructure. The site is well-structured, mobile-optimized, and SEO-friendly, providing rich content and comprehensive documentation. However, the security posture is weakened by the absence of a valid SSL certificate and lack of modern TLS protocols, which is a critical vulnerability. Privacy compliance is basic, with no visible cookie consent mechanisms and limited public contact information. Overall, the website demonstrates strong business credibility and technical maturity but requires urgent improvements in security and privacy compliance to enhance trust and protect users.

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

5 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: Facebook, Twitter, LinkedIn, YouTube

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

Business context

Business profile

Symfony SAS leverages an open-source business model augmented by commercial offerings including training, certification, and cloud hosting partnerships. Their competitive advantage lies in a mature, widely adopted PHP framework with a vibrant community and ecosystem. Revenue streams likely include training fees, certification exams, hosting subscriptions via Platform.sh, and quality/performance tools like SymfonyInsight and Blackfire. The target customer segments are PHP developers, software teams, and enterprises seeking robust web application frameworks and professional support. Growth indicators include active community engagement, regular conferences, and extensive educational content. The partnership ecosystem with Platform.sh, SensioLabs, and Blackfire strengthens their market position and service portfolio. Strategic observations suggest focusing on enhancing security and privacy compliance to meet evolving regulatory requirements and customer expectations.

Security posture

The current security maturity level of symfony.com is moderate but with critical gaps. The absence of a valid SSL certificate and lack of TLS protocol support expose users to potential interception and downgrade attacks. No HTTP security headers were detected, and HSTS is not enabled, reducing protection against common web attacks. Email authentication is well-configured with SPF and DMARC records, mitigating phishing risks. No incident response or vulnerability disclosure information is publicly available, indicating limited transparency in security operations. Privacy compliance is minimal, with no cookie consent mechanisms or explicit GDPR adherence visible. The site does not expose sensitive data or vulnerable libraries in the analyzed content. Overall, the security culture appears focused on code quality and performance but needs to prioritize transport security and privacy controls to reduce risk and comply with regulations.

Recommendations

  1. Implement and maintain a valid SSL/TLS certificate supporting TLS 1.2 and TLS 1.3 protocols to secure all web traffic.
  2. Enable HTTP Strict Transport Security (HSTS) with includeSubDomains and preload directives to enforce HTTPS usage.
  3. Add essential security headers such as Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy.
  4. Deploy a cookie consent mechanism to comply with privacy regulations and inform users about tracking.
  5. Publish a clear vulnerability disclosure policy and incident response contact information to enhance transparency and trust.

Technical notes

Notes

The website is built on a robust technical infrastructure using the Symfony PHP framework, Bootstrap for responsive design, and modern JavaScript libraries like Stimulus and Asciinema-player. Hosting is managed via Cloudflare DNS and nameservers, with Platform.sh as the recommended PaaS for Symfony projects. Performance is moderate with a page load time of approximately 4.7 seconds and 80 resources loaded. The site is mobile-optimized and accessible, with good SEO practices including meta tags, Open Graph, and JSON-LD structured data. However, the lack of a valid SSL certificate and outdated SSL/TLS configuration represent significant technical risks. There is no CMS detected, indicating a custom or framework-based site. Opportunities exist to modernize security configurations and improve privacy compliance to align with best practices and regulatory demands.
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.
