58/100

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

The website ari.lt is a personal portfolio and open source project hub for Arija A. (Ari Archer), a young Lithuanian open source developer. The site showcases a variety of self-hosted services, open source projects, and community engagement tools such as a guestbook. The business model is centered around open source software development and providing free and private services to the community. The site is well-positioned in a niche market of technology enthusiasts and open source advocates. Technically, the site uses a modern tech stack including Python with Flask, C, JavaScript, and custom static site generation. It is hosted by HOSTINGER operations, UAB, with a fast and mobile-optimized design. SEO and accessibility are well implemented, and the site publishes source code and cryptographic keys openly, enhancing transparency. From a security perspective, HTTPS is enforced and email communications are protected with OpenPGP keys. The guestbook employs CAPTCHA and email confirmation to mitigate spam. However, the site lacks explicit security headers and formal privacy and cookie policies, which are areas for improvement. No WAF or blocking mechanisms are detected, and the domain registration is consistent and legitimate. Overall, the site is trustworthy, professionally designed, and secure for its purpose, but would benefit from enhanced privacy compliance and security hardening to align with best practices.

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. GDPR outside view

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

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • 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

  2. 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.

    • High

      Weak SSL Key Length

      SSL certificate uses 256-bit key, which is considered weak

      What to do: Use at least 2048-bit RSA or 256-bit ECC key

      • CWE-326
      • OWASP A04:2025
      • Mozilla TLS: Mozilla Server Side TLS 6.0 intermediate: rsa_key_size 2048

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

  • Security headers: did not complete in this scan.
  • 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

ari.lt operates as a small-scale personal technology and open source development platform. Its competitive advantage lies in transparency, community engagement, and a broad portfolio of self-hosted services. The business model is non-commercial, focusing on free and open source software and services. The target audience includes developers, open source enthusiasts, and users seeking privacy-respecting services. Growth indicators include active project repositories and community interaction via the guestbook. Partnerships are informal and community-based, with links to various open source and personal sites. The site reflects a strong personal brand with a focus on technical excellence and openness.

Security posture

The security posture of ari.lt is moderate to good. HTTPS is properly configured, and the site uses OpenPGP keys for email security. The guestbook form includes CAPTCHA and email verification to reduce spam and abuse. However, the absence of security headers such as Content-Security-Policy and X-Frame-Options reduces defense in depth. No vulnerability disclosure policy or security.txt file is present, limiting formal incident response channels. The site shows awareness of security principles but could improve by adopting additional best practices and formal policies to enhance compliance and resilience.

Recommendations

  1. Implement and enforce security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  2. Publish a comprehensive privacy policy and cookie policy to improve GDPR compliance and user trust.
  3. Create and maintain a security.txt file to facilitate vulnerability disclosure and incident response.
  4. Regularly audit and sanitize guestbook inputs to prevent XSS and other injection attacks.
  5. Enhance transparency by documenting data retention policies and user data handling practices.

Technical notes

Notes

The website is built on a solid technical foundation using Python (Flask), C, and JavaScript, with a custom static site generator powering the blog. Hosting is provided by HOSTINGER operations, UAB, ensuring reliable infrastructure. The site loads quickly and is mobile optimized, with good SEO metadata and accessibility features. The use of open source licenses and published source code indicates low technical debt and a commitment to maintainability. Opportunities exist to modernize security configurations and formalize compliance documentation to reduce technical risks.
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.
