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

The website herdagdelen.com serves as a personal academic and professional portfolio for Amaç Herdağdelen, a computational social scientist with expertise in computational linguistics, AI, and social sciences. The site highlights his research interests, past work at Facebook, and co-founding of a data visualization collective. The content is well-structured and professionally presented, targeting academics, researchers, and data science professionals interested in social data analysis and visualization. Technically, the site is built using the Hugo static site generator with the PaperMod theme, leveraging modern web technologies such as Font Awesome icons and Google Analytics for tracking. The site performs well with good mobile optimization and basic accessibility features. However, it lacks advanced SEO and accessibility enhancements. From a security perspective, the site uses HTTPS and includes no forms or input fields, reducing attack surface. However, it lacks explicit security headers and does not provide privacy or cookie policies, which impacts compliance and user trust. No vulnerability disclosure or incident response information is present, limiting transparency for security issues. Overall, the site is a solid personal academic portfolio with good technical implementation but has room for improvement in privacy compliance, security best practices, and transparency. Strategic enhancements in these areas would improve trustworthiness and compliance posture.

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

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

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

    • Critical

      No HTTPS encryption

      GDPR requires appropriate security measures for personal data

      What to do: Implement SSL/TLS certificate for HTTPS

  2. 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

  3. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • Critical

      No HTTPS Encryption

      Website does not use HTTPS encryption, making all data transmission vulnerable to interception

      What to do: Implement SSL/TLS certificate and redirect all HTTP traffic to HTTPS

  4. 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"

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 researcher rather than a commercial business entity. It positions Amaç Herdağdelen as an expert in computational social sciences with a strong academic and industry background, including work at Facebook and co-founding a data visualization collective. The business model is primarily personal branding and dissemination of research outputs. The target audience includes academics, data scientists, and policy researchers. The site leverages partnerships such as Çilek Ağacı for collaborative projects. There is no indication of revenue streams or commercial transactions. The site’s market presence is niche but credible within academic and data science communities.

Security posture

The security posture is moderate. The site benefits from HTTPS and minimal attack surface due to lack of forms or user input. However, it lacks important security headers such as Content-Security-Policy and Strict-Transport-Security, which are recommended for modern websites. The absence of privacy and cookie policies and no visible incident response or vulnerability disclosure mechanisms indicate gaps in compliance and transparency. Google Analytics is used without a visible cookie consent mechanism, which may raise GDPR compliance concerns. No exposed sensitive data or vulnerable libraries were detected. Overall, the site is low risk but could improve security maturity and compliance.

Recommendations

  1. Add a comprehensive privacy policy and cookie policy with GDPR compliance details.
  2. Implement security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Provide clear contact information and consider adding a security.txt file for vulnerability disclosure.
  4. Enhance accessibility features to meet WCAG standards.
  5. Review and disclose data retention policies related to Google Analytics tracking.

Technical notes

Notes

The website is built on a modern static site generator (Hugo) with the PaperMod theme, ensuring fast loading times and good mobile responsiveness. It uses Font Awesome for icons and Google Analytics for visitor tracking. The site has valid meta tags but lacks advanced SEO optimizations. No CMS or dynamic backend is detected, reducing complexity and security risks. Hosting provider details are not explicit. The site’s technical debt appears low, but improvements in accessibility and security headers would enhance robustness. The absence of forms reduces risk but also limits interactive capabilities.
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.
