plzPLZ.at is a specialized online service providing postal code search functionality for cities and streets in Austria. The website is operated by Team Zones.sk and targets general users seeking postal code information. It offers autocomplete search features and lists popular postal codes, enhancing user convenience. The site is well-positioned in its niche market, focusing on Austrian postal code data with a clear and consistent branding approach. Technically, the website employs a modern tech stack including jQuery, jQuery UI, Google Fonts, Google Tag Manager, and Google Adsense for advertising and analytics. Hosting is provided by websupport.sk, a known hosting provider. The site is mobile-optimized and demonstrates good SEO practices, although accessibility features are basic. Performance is moderate, with room for optimization. From a security perspective, the site uses HTTPS and a comprehensive consent management platform to comply with GDPR cookie and tracking regulations. However, explicit security headers are not detected, and no formal security or incident response policies are published. The site does not expose sensitive data and uses secure forms for user input. Advertising partners and tracking vendors are numerous but transparently disclosed via the consent mechanism. Overall, the website presents a moderate risk profile with good privacy compliance and a solid technical foundation. Strategic improvements in security headers, explicit privacy and security policies, and enhanced contact information would strengthen trust and compliance. The domain registration is consistent and legitimate, supporting the website's credibility.

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

8 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 Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

  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"

      • OWASP A04:2025
      • ASVS V3.4.1

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

plzPLZ.at operates in the information services sector, focusing on postal code lookup for Austria. Its business model is informational, likely monetized through advertising networks such as Google Adsense and other ad partners. The target audience includes residents, businesses, and organizations needing postal code data. The partnership with zones.sk suggests a broader ecosystem of location-based services. The website's competitive advantage lies in its specialized focus and user-friendly search features. Growth potential exists through expanding services or geographic coverage. The advertising ecosystem is robust, indicating diversified revenue streams. However, the lack of explicit business contact details and formal policies may limit institutional trust.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is enforced, and a GDPR-compliant consent management platform is implemented, indicating awareness of privacy regulations. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options is a gap. No incident response or security policy is published, and no dedicated security contact is provided. The site uses multiple third-party advertising and tracking vendors, which increases the attack surface and privacy risks, though these are managed via consent. No vulnerabilities or malware indicators are detected in the provided data. Overall, the security posture is adequate for an informational website but could be improved with enhanced security controls and transparency.

Recommendations

  1. Implement and configure security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a clear privacy policy and terms of service on the website to improve transparency and legal compliance.
  3. Provide explicit incident response contact information such as security@ or abuse@ email addresses.
  4. Regularly audit third-party scripts and advertising vendors to minimize privacy and security risks.
  5. Enhance accessibility features to improve usability for all users and comply with accessibility standards.

Technical notes

Notes

The website uses a traditional web stack with jQuery and jQuery UI for UI components and autocomplete functionality. Google Fonts are used for typography, and Google Tag Manager and Adsense are integrated for analytics and monetization. Hosting is via websupport.sk, a regional hosting provider. The site is mobile-optimized and includes meta tags for SEO and social sharing (Open Graph). Performance is moderate, with potential improvements in loading speed and resource optimization. No modern frontend frameworks (React, Angular, Vue) or CMS platforms are detected, indicating a custom or lightweight implementation. The consent management platform is robust and integrated well. Technical risks include reliance on multiple third-party scripts and lack of advanced security headers.
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.
