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

4 findings rated critical or high. Fix these first.

  1. 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';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

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

ECAL's market positioning as a leader in calendar marketing is reinforced by its extensive client portfolio including globally recognized brands like the Premier League, Disney, and NBA. Their SaaS business model focuses on providing scalable calendar synchronization and marketing tools that integrate seamlessly with websites, apps, and social media channels. Revenue streams likely include subscription plans and enterprise solutions. The company targets businesses requiring event-based communications across multiple industries, leveraging partnerships with payment processors and marketing platforms. Growth indicators include continuous product enhancements, a free trial offering, and active content marketing via blogs and case studies. The partnership ecosystem includes domains like staynplay.co and hyperid.co, indicating strategic collaborations. ECAL's operations span multiple global offices, enhancing their international market reach.

Security posture

ECAL exhibits a solid security posture with mandatory HTTPS, domain transfer protection, and GDPR-compliant cookie management. The use of Google reCAPTCHA mitigates automated abuse risks. However, the absence of DNSSEC and advanced HTTP security headers such as Content-Security-Policy and X-Frame-Options represents areas for improvement. No direct security policy or incident response contacts are published, which could hinder transparency and responsiveness in case of security incidents. No vulnerabilities or exposed sensitive data were detected in the HTML content. The security score is strong but could be enhanced by adopting additional best practices and publishing formal security documentation.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Implement comprehensive HTTP security headers including Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options.
  3. Publish a dedicated security policy page detailing security practices and incident response procedures.
  4. Establish and publicize a vulnerability disclosure program or security.txt file to encourage responsible reporting.
  5. Enhance accessibility features to improve compliance and user experience for all users.

Technical notes

Notes

The website leverages a mature WordPress CMS with WPBakery Page Builder, integrating multiple third-party scripts for analytics, marketing, and user engagement such as Google Tag Manager, Microsoft Clarity, Calendly, and Zoho CRM. Hosting appears to be on AWS infrastructure, supported by AWS DNS servers. The site demonstrates good mobile responsiveness and SEO optimization with proper meta tags and structured data (JSON-LD). Performance is moderate, with asynchronous loading of scripts and optimized images. Some technical debt is evident in the use of older jQuery versions and multiple Google Tag Manager containers, which could be consolidated. Overall, the technical infrastructure supports a robust and scalable marketing platform but could benefit from modernization and enhanced security configurations.
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.
