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

AeroHosting.cz is a Czech webhosting and domain registration provider offering professional hosting services with support for PHP (versions 5.4 to 8.4), ASP.NET, MariaDB, MSSQL, and related technologies. The company emphasizes quality hosting with features such as free SSL certificates via Let's Encrypt, DNSSEC support, and daily backups. The website targets individuals and businesses in the Czech Republic seeking reliable webhosting and domain management solutions. The company claims over 20 years of experience, positioning itself as a trusted local provider. Technically, the website uses a mix of Linux and Windows hosting environments with Apache and IIS servers, and client-side scripts including jQuery 1.10.1. The site design is professional and content-rich, though mobile optimization and accessibility are basic. Security posture is moderate with HTTPS enforced and DNSSEC supported, but lacks visible security headers and uses an outdated jQuery version which may pose risks. Privacy and cookie policies are not explicitly presented, indicating room for compliance improvement. WHOIS data is unavailable, which reduces trustworthiness and requires further verification. Overall, AeroHosting.cz presents a solid business offering with moderate technical maturity and security awareness but should enhance privacy compliance and update technical components to improve trust and security.

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

10 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

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 in the technology sector focusing on webhosting and domain registration services primarily for the Czech market. Its business model is service-based, generating revenue from hosting plans and domain registrations. The website highlights competitive pricing, free SSL certificates, and extended hosting periods as key advantages. The presence of social media links and customer support contact details indicates active customer engagement. The lack of WHOIS data is a notable gap but does not negate the company's apparent market presence. The company appears to be a small-sized provider with a focused niche. Growth indicators include support for latest PHP versions and continuous service updates. No parent or subsidiary companies are identified. The company ecosystem includes partnerships with domain registries and payment processors, though these are not explicitly detailed.

Security posture

The security posture is moderate. The website enforces HTTPS and offers free SSL certificates, which is a positive security practice. DNSSEC support is mentioned, enhancing domain security. However, the absence of visible security headers such as Content Security Policy, HSTS, or X-Frame-Options reduces the overall security robustness. The use of an outdated jQuery version (1.10.1) introduces potential vulnerabilities. No explicit privacy or security policies are published, and no incident response contacts are provided. The lack of WHOIS data also raises concerns about domain legitimacy. Overall, while basic security measures are in place, there is room for improvement in security best practices, compliance, and transparency.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies to improve GDPR compliance.
  2. Update client-side libraries such as jQuery to the latest secure versions to mitigate vulnerabilities.
  3. Add and configure security headers (CSP, HSTS, X-Frame-Options) to enhance web security.
  4. Provide explicit incident response and security contact information to improve transparency and trust.
  5. Verify and publish domain WHOIS information to strengthen legitimacy and trustworthiness.

Technical notes

Notes

The website uses a traditional technology stack supporting PHP (5.4 to 8.4), ASP.NET, MariaDB, and MSSQL databases, running on Linux and Windows servers with Apache and IIS. Client-side scripts include jQuery 1.10.1 and various slider and animation plugins. The site has a moderate performance profile with basic mobile optimization and accessibility. SEO is basic but includes relevant meta tags and keywords. The absence of a CMS suggests a custom or proprietary platform. Hosting provider details are not explicitly stated. The site could benefit from modernization of libraries and improved mobile responsiveness. No analytics or tracking scripts were detected, indicating minimal user tracking. Overall, the technical infrastructure is functional but could be enhanced for performance, security, and user experience.
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.
