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

Gabriel Pereira's website is a personal professional portfolio showcasing his bio, projects, writing, speaking engagements, and blog. The site targets a general audience interested in his professional work and thought leadership. The business model is that of an individual personal brand without commercial transactions or e-commerce. The website is built using the Hugo static site generator and leverages modern web technologies including jQuery, FontAwesome, Google Analytics, and Cloudflare Insights. Hosting appears to be via Cloudflare services. The site is well-structured with clear navigation and good mobile optimization, though accessibility features are basic. Security posture is moderate with some best practices like IP anonymization in Google Analytics but lacks explicit security headers and privacy policies. The domain WHOIS data is missing, indicating potential issues with domain registration legitimacy. Overall, the site is professional and safe but would benefit from improved compliance and security measures.

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

7 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 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 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

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

The website represents an individual professional's online presence rather than a corporate entity. There is no evidence of a parent company or subsidiaries. The target audience includes peers, potential collaborators, and followers of Gabriel Pereira's work. The site does not engage in commercial activities or advertising beyond basic tracking. The lack of privacy and cookie policies and absence of contact phone numbers or physical addresses limit business credibility. The use of modern static site technology and analytics tools indicates a moderate level of digital maturity. No partnerships or related domains were identified.

Security posture

The security maturity level is basic to moderate. The site uses HTTPS (inferred from external scripts loaded via HTTPS) and anonymizes IP addresses in Google Analytics, which is positive. However, no security headers such as Content-Security-Policy or X-Frame-Options were detected. There are no forms or inputs that could expose vulnerabilities, but the absence of privacy and cookie policies indicates compliance gaps with GDPR and other regulations. No incident response or vulnerability disclosure information is provided. The missing WHOIS data raises concerns about domain legitimacy and continuity, which is a critical security and trust issue.

Recommendations

  1. Register or verify domain WHOIS information to ensure domain legitimacy and continuity.
  2. Publish comprehensive privacy and cookie policies to improve GDPR compliance and user trust.
  3. Implement security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Add contact phone numbers and physical address if applicable to enhance business credibility.
  5. Consider adding a vulnerability disclosure policy or security contact information to improve security posture.

Technical notes

Notes

The website is built on the Hugo static site generator, ensuring fast and reliable performance. It uses jQuery 3.5.1, FontAwesome 5.7.2 for icons, and integrates Google Analytics and Google Tag Manager for visitor tracking. Cloudflare Insights is used for performance and security monitoring. The site is mobile optimized with responsive design and clear navigation. However, no advanced accessibility features were detected. The absence of explicit security headers and privacy policies indicates areas for technical improvement. Hosting via Cloudflare provides some security and performance benefits. Overall, the technical infrastructure is modern and adequate for a personal portfolio site but could be enhanced with better security and compliance 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.
