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.

Priority findings

6 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

    • 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. 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"

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

ShortURL.at operates in the technology sector as a URL shortening service, leveraging the brand and infrastructure of NameSilo, LLC. Its competitive advantage lies in its association with a reputable domain registrar, providing trust and stability. The business model focuses on free URL shortening with monetization through advertising and premium account upgrades. Target customers include individual users, marketers, and businesses needing link management and analytics. The partnership ecosystem includes advertising networks and analytics providers, supporting revenue generation and user insights. Growth indicators include integration of advanced features like API access and QR codes. The company maintains a clear market niche with consistent branding and a straightforward value proposition.

Security posture

The website demonstrates a moderate to good security maturity level, with HTTPS enforced and secure form handling. The presence of third-party scripts and advertising networks introduces some risk, but no immediate vulnerabilities are detected. Privacy policies and cookie consent mechanisms indicate compliance with GDPR and related regulations. However, the absence of explicit security policies, incident response contacts, and security.txt files suggests gaps in formal security governance and incident management readiness. The site would benefit from implementing comprehensive security headers and publishing clear security and incident response documentation to enhance transparency and preparedness.

Recommendations

  1. Implement comprehensive security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to mitigate common web attacks.
  2. Publish a dedicated security policy and incident response plan accessible to users and security researchers.
  3. Introduce a security.txt file to facilitate responsible vulnerability disclosure and improve security communication.
  4. Enhance accessibility features to meet WCAG standards, improving usability for all users.
  5. Provide direct contact information for security and abuse reporting to strengthen incident response capabilities.

Technical notes

Notes

The website is custom-built with a modern front-end stack utilizing HTML5, CSS3, and JavaScript. It integrates multiple third-party services for chat support (Intercom), analytics (Google Tag Manager), and advertising (various ad networks). The site is mobile responsive and optimized for performance with preloading and preconnect hints. No CMS or major frameworks were detected, indicating a bespoke solution. Hosting appears stable and likely managed by NameSilo. Performance is moderate with room for optimization, especially in script loading and accessibility compliance. The technical implementation supports the business goals effectively but could benefit from enhanced security and accessibility improvements.
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.
