Risk levelMedium

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

The website aso1.net operates as a domain dedicated to ad serving and ad tracking, with minimal publicly accessible content. The business model focuses on providing advertising infrastructure likely targeting marketers and advertisers. The domain is stable, registered since 2015, and uses Cloudflare for DNS and hosting services, indicating a basic level of technical infrastructure. However, the website lacks substantive content, business information, and user engagement features such as contact forms or policies. Security posture is basic with no advanced headers or DNSSEC enabled, and privacy compliance is absent due to missing policies. Overall, the site presents a low-risk profile but lacks transparency and professionalism, limiting trust and 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

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.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The domain appears to serve as a backend or infrastructure component for ad serving rather than a customer-facing business. Its market position is unclear due to lack of public information. The business model likely involves serving ads and tracking user interactions for clients. There are no visible partnerships, certifications, or trust indicators. The absence of contact details and policies suggests a minimal operational footprint or a focus on automated ad services rather than direct customer engagement.

Security posture

Security measures are minimal. The domain uses HTTPS and Cloudflare DNS but lacks DNSSEC and security headers. No incident response or vulnerability disclosure information is available. The absence of privacy and cookie policies indicates non-compliance with GDPR and related regulations. No known vulnerabilities or exposed sensitive data were detected in the limited content. Overall, the security posture is basic and could be improved by implementing standard security best practices and compliance documentation.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve compliance and user trust.
  2. Enable DNSSEC to enhance domain security against DNS spoofing.
  3. Add security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security.
  4. Provide clear contact information and incident response channels to improve transparency.
  5. Enhance website content and branding to improve professionalism and trustworthiness.

Technical notes

Notes

The website uses Cloudflare nameservers, indicating reliance on a reputable hosting and DNS provider. The HTML content is minimal with no metadata, scripts, or external links detected. No CMS or frameworks are identified. Performance is likely moderate due to Cloudflare's infrastructure, but lack of content limits user engagement. The site lacks SEO optimization and accessibility features. Technical debt appears low due to minimal implementation but modernization opportunities exist to add standard web features and compliance elements.
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.
