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

The website timafei.dev is a personal academic portfolio for Timafei Hushchyn, a master's student in computer science at the University of Massachusetts Amherst. The site primarily serves as a professional and academic profile showcasing Tim's research interests in algorithms, distributed systems, and social computing, along with personal interests. It targets academic peers, potential collaborators, and personal contacts rather than commercial customers. The business model is non-commercial, focusing on information sharing and networking. Technically, the site is built with basic HTML, CSS, and JavaScript, including Google Fonts for typography. It lacks advanced frameworks or CMS platforms and appears to be self-hosted or hosted on a simple platform. Performance is moderate with basic mobile optimization and accessibility features. SEO is minimal but sufficient for a personal site. From a security perspective, the site does not implement common security headers and lacks privacy and cookie policies, which are important for compliance and user trust. No forms or data collection mechanisms are present, reducing exposure to input-based vulnerabilities. The WHOIS data is consistent with the website content and owner identity, indicating legitimacy. No WAF or blocking mechanisms were detected. Overall, the site is low risk but could benefit from improved security practices, privacy compliance, and enhanced technical features to improve user experience and trustworthiness.

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. 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

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.

Dark web exposure

Add-on

Leaked records that mention timafei.dev, from OffSeq Breach.

No leaked records found

Breach holds no records for timafei.dev right now. New leaks arrive continuously, so monitoring on Breach alerts you if that changes.

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 a personal academic portfolio rather than a commercial business. It does not engage in revenue-generating activities or commercial transactions. The target audience includes academic peers, researchers, and personal contacts. The site leverages external links to university labs and initiatives, indicating collaboration and academic networking. There are no indications of partnerships, subsidiaries, or parent companies. The site’s growth potential is limited to academic and personal branding. The lack of business-related policies and certifications aligns with its non-commercial nature.

Security posture

The security posture of the website is basic. HTTPS usage is unknown but recommended. No security headers such as Content-Security-Policy or Strict-Transport-Security are detected, which could expose the site to common web attacks. The absence of forms reduces attack surface but also limits interactivity. No vulnerability disclosures or incident response contacts are provided, which is typical for personal sites but could be improved. Privacy compliance is lacking, with no GDPR indicators or cookie consent mechanisms. Overall, the site is low risk but would benefit from adopting standard security best practices.

Recommendations

  1. Implement HTTPS to ensure encrypted communication.
  2. Add standard security headers including Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  3. Publish privacy and cookie policies to improve compliance and user trust.
  4. Add contact information for security incidents or abuse reporting.
  5. Improve mobile responsiveness and accessibility features for better user experience.

Technical notes

Notes

The website uses a simple technology stack consisting of HTML5, CSS, JavaScript, and Google Fonts. There is no evidence of a CMS or advanced frameworks. The site loads external resources from trusted domains such as Google Fonts and GitHub. Performance is moderate with no explicit optimization techniques detected. The site is minimally optimized for mobile devices and accessibility. There is no evidence of analytics or tracking scripts, which reduces privacy concerns but also limits insights into user behavior. The technical implementation is straightforward but could be modernized with responsive design frameworks and enhanced SEO practices.
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.
