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

The website giannirosato.com serves as a personal portfolio and informational hub for Gianni Rosato, a student and open-source software enthusiast specializing in digital compression algorithms. The site highlights Gianni's work on video and image compression technologies, accessible encoding tools, and public resources related to codecs such as AV1, JPEG XL, and QOI. The target audience includes students, programmers, and open-source community members interested in multimedia compression. The business model is primarily personal branding and knowledge sharing, with no commercial transactions evident. Technically, the site is built with standard HTML5, CSS3, and JavaScript, incorporating Umami Analytics for privacy-conscious visitor tracking. Hosting is managed via Packetframe, inferred from the nameservers. The site is mobile-optimized and performs well with good SEO practices, though accessibility features are basic. No CMS or major frameworks are detected, indicating a lightweight, custom-built site. From a security perspective, the site uses HTTPS and has domain registration protections such as clientDeleteProhibited and clientTransferProhibited statuses. However, DNSSEC is not enabled, and no security headers are present, which are areas for improvement. There is no privacy or cookie policy, nor a vulnerability disclosure or incident response policy published. The site does not collect data via forms, limiting exposure to input-based vulnerabilities. Overall, the website is safe, professional, and trustworthy for its intended purpose, with moderate security posture and room for enhanced privacy compliance. Strategic recommendations include adding privacy and cookie policies, enabling DNSSEC, implementing security headers, and publishing a vulnerability disclosure policy to improve trust and security maturity.

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

8 findings rated critical or high. Fix these first.

  1. 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

  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

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

Gianni Rosato operates as an individual contributor in the technology sector, focusing on digital compression and open-source software development. The website positions Gianni as a knowledgeable student and programmer with niche expertise in codecs and encoding tools. The business model is informational and community-oriented, leveraging open-source contributions and personal projects. The site links to multiple reputable open-source projects and social platforms, indicating a strong partnership ecosystem within the open-source community. Growth indicators include active GitHub contributions and engagement with commercial encoder projects. Revenue streams are not evident, suggesting a non-commercial or early-stage personal brand. The partnership ecosystem includes Two Orioles and SVT-AV1 projects, enhancing credibility and market positioning within multimedia compression technology.

Security posture

The security posture of giannirosato.com is moderate. The site benefits from HTTPS encryption and domain registration protections that prevent unauthorized transfers or deletions. However, the absence of DNSSEC leaves the domain vulnerable to DNS spoofing attacks. The lack of security headers such as Content-Security-Policy and X-Frame-Options reduces defense-in-depth against common web attacks. No privacy or cookie policies are published, which is a compliance gap under GDPR and related regulations. The site does not have a vulnerability disclosure or incident response policy, limiting transparency and readiness for security incidents. No forms or input fields reduce the attack surface, and no vulnerable libraries were detected. Overall, the site demonstrates basic security hygiene but should enhance policies and technical controls to improve resilience and compliance.

Recommendations

  1. Enable DNSSEC to protect against DNS spoofing and improve domain security.
  2. Publish a comprehensive privacy policy and cookie policy to enhance GDPR compliance and user trust.
  3. Implement security headers such as Content-Security-Policy, X-Content-Type-Options, and X-Frame-Options to mitigate common web vulnerabilities.
  4. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible security reporting.
  5. Consider adding accessibility improvements to better serve users with disabilities and improve compliance.

Technical notes

Notes

The website is built using standard web technologies including HTML5, CSS3, and JavaScript, with no detected CMS or major frameworks, indicating a custom or static site approach. The inclusion of Umami Analytics shows a preference for privacy-focused analytics over mainstream providers. Hosting is inferred to be via Packetframe based on DNS nameservers. The site is mobile-optimized and loads quickly, with proper meta tags for SEO and social sharing. There is some redundancy in CSS includes but no broken elements detected. The absence of security headers and DNSSEC are technical gaps. No forms or complex interactive elements reduce technical complexity and potential vulnerabilities. Overall, the technical infrastructure is modern, lightweight, and performant but could benefit from enhanced security configurations.
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.
