Risk levelMedium

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

attendio.online is a Slovak-based small technology business operated by Revoltapp s.r.o., likely providing an online event attendance or ticketing platform. The website content is minimal, with no detailed descriptions or user interaction forms visible. The technical infrastructure includes usage of Google Analytics and Tag Manager for tracking, hosted on DigitalOcean with DNS configured accordingly. The website lacks privacy, cookie, and terms of service policies, and no contact information is provided, which limits user trust and compliance with data protection regulations. Security posture is basic with no advanced headers or DNSSEC enabled, though the domain registration is transparent and consistent with the business origin. Overall, the site appears functional but underdeveloped in content, security, and compliance aspects.

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

7 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 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

    • 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

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 online event attendance or ticketing services. Market positioning and competitive advantages are unclear due to lack of content. The business model likely revolves around digital event management. The target audience is general users interested in online events. No partnerships or subsidiaries are identified. Growth indicators and revenue streams are not discernible from the website. The company is relatively young, founded in 2020, and operates primarily in Slovakia.

Security posture

The security maturity level is low to moderate. The absence of DNSSEC and security headers indicates potential vulnerabilities. No incident response or security policy information is provided, limiting transparency. The use of Google Analytics and Tag Manager without visible consent mechanisms raises privacy compliance concerns. No exposed sensitive data or known vulnerabilities are detected from the provided content. The domain registration status provides some protection against unauthorized transfers. Overall, the security posture requires significant improvements to meet best practices and regulatory compliance.

Recommendations

  1. Implement and publish comprehensive privacy and cookie policies with GDPR compliance.
  2. Add clear contact information including support and incident response channels.
  3. Enable DNSSEC and configure security headers such as Content-Security-Policy and Strict-Transport-Security.
  4. Improve website content quality and user experience with detailed business descriptions and navigation.
  5. Establish a vulnerability disclosure policy or security.txt file to enhance transparency and trust.

Key observations

  1. Website content is minimal and lacks detailed business or legal information.
  2. No privacy, cookie, or terms of service policies found.
  3. No contact information or forms for user interaction detected.
  4. Uses Google Analytics and Tag Manager for tracking without visible consent mechanisms.
  5. Hosted on DigitalOcean with DNS configured accordingly.
  6. No security headers or advanced security configurations detected in the HTML content.
  7. WHOIS data is transparent and consistent with the website's Slovak origin.
Technical notes

Notes

The website uses a modern tech stack including Google Analytics, Google Tag Manager, Google Fonts, and FontAwesome icons. Hosting is provided by DigitalOcean with DNS configured accordingly. The HTML content is minimal and lacks meta tags for SEO optimization. Mobile optimization and accessibility are basic but present. No CMS or frameworks are detected. Performance is moderate given the minimal content. Technical debt is low but modernization opportunities exist in security and content management. The absence of security headers and DNSSEC are technical risks that should be addressed to improve resilience.
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.
