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

Tautek UAB is a Lithuanian software development company specializing in ASP.NET Core web applications, Windows UWP apps, cross-platform mobile development using Xamarin and MAUI, and IT consulting focused on .NET and Azure platforms. The company serves business clients including notable firms such as Cognizant and Bluebridge, positioning itself as a niche technology service provider with a small but professional team. The website reflects a modern technical infrastructure leveraging Bootstrap for frontend styling and integrates Google Analytics and Tag Manager for user tracking. Hosting is likely on Microsoft Azure, consistent with their service offerings. Security posture is moderate; while HTTPS is presumably enabled, the site lacks explicit security headers and formal privacy or cookie policies, which impacts compliance and trust. WHOIS data is unavailable due to query limits, limiting domain legitimacy verification. Overall, the website is professional and functional with clear contact information and client references, but improvements in security and privacy transparency are recommended.

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

      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

  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';…

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 company operates a service-based business model focused on custom software development and IT consulting within the technology sector. Its client base includes established companies, indicating a stable market position. The presence of projects like cheapwatcher.com suggests active product development or partnerships. The business targets organizations requiring Microsoft technology expertise and cloud solutions. Growth potential is supported by a skilled team with over 10 years of experience each. However, the lack of public privacy and security policies may limit appeal to highly regulated sectors. The company maintains a consistent brand image and professional online presence, supporting credibility and client trust.

Security posture

The security maturity level is moderate. The website uses HTTPS and avoids exposing sensitive data in its HTML content. However, the absence of security headers such as Content Security Policy, HSTS, and X-Frame-Options reduces protection against common web attacks. No vulnerability disclosures or incident response contacts are published, which limits transparency and readiness perception. The lack of privacy and cookie policies also indicates gaps in GDPR compliance. No known vulnerabilities or malware were detected in the content. Overall, the security posture is adequate for a small technology firm but requires enhancements to meet best practices and regulatory expectations.

Recommendations

  1. Implement comprehensive security headers including CSP, HSTS, X-Frame-Options, and X-Content-Type-Options to strengthen web security.
  2. Publish clear privacy and cookie policies with GDPR compliance statements and implement a cookie consent mechanism.
  3. Establish and publicize an incident response policy and security contact channels to improve transparency and trust.
  4. Enable DNSSEC for the domain to enhance DNS security and integrity.
  5. Improve website accessibility features and SEO optimization to enhance user experience and discoverability.

Technical notes

Notes

The website is built using modern web technologies including ASP.NET Core for backend services and Bootstrap 5 for responsive frontend design. It integrates Google Analytics and Tag Manager for tracking user interactions. The hosting environment is likely Microsoft Azure, consistent with the company's service offerings. Performance is moderate with good mobile optimization. The site lacks a CMS and appears custom-developed. There is no evidence of technical debt or outdated libraries. However, the absence of security headers and privacy compliance features indicates areas for modernization. Overall, the technical implementation supports the business needs but can be improved for security and compliance.
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.
