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

WonderPush is a technology company specializing in push notification services for web, iOS, and Android platforms. The company offers unlimited push notifications starting at €1 per month, targeting developers and businesses seeking to engage users via mobile and web notifications. Positioned as a GDPR-compliant and fast service, WonderPush is trusted by over 5000 developers and notable brands, and is a subsidiary of Brevo, a marketing and sales toolkit provider. The website is professionally designed, mobile-optimized, and provides clear navigation and relevant content about its services and features. Technically, the website is built on WordPress using the Divi theme, leveraging modern web technologies including JavaScript, Matomo analytics for privacy-conscious tracking, and Google Fonts. Hosting is claimed to be on Google Cloud, with European data hosted in Europe to comply with GDPR. The site demonstrates good performance and accessibility, though explicit security headers are not detected in the provided data. From a security perspective, the site enforces HTTPS and claims GDPR compliance with open source SDKs to minimize unnecessary data collection. However, the absence of explicit privacy and cookie policies in the accessible content, lack of security.txt or vulnerability disclosure, and missing WHOIS domain registration data introduce some risk factors. The domain WHOIS query returned no match, which is unusual for an established business and suggests further verification is needed to confirm domain legitimacy. Overall, the website presents a professional and trustworthy front with strong business credibility and technical maturity. Strategic improvements in publishing clear privacy and security policies, enhancing security headers, and clarifying domain registration details would strengthen the security posture and trustworthiness further.

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

5 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. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • 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

WonderPush operates in the technology sector, providing push notification services with a subscription-based business model. Its market positioning is strong among developers and businesses requiring user engagement tools, supported by partnerships and acquisition by Brevo. The company leverages automation, segmentation, and real-time analytics to differentiate its offerings. Revenue streams likely include monthly subscriptions and additional fees per subscriber. The target customer segments include e-commerce, media, sports, and real estate sectors, as evidenced by case studies. Growth indicators include a large volume of push notifications sent monthly and endorsements from reputable clients. The partnership ecosystem includes Brevo as the parent company, enhancing marketing and sales capabilities. Operationally, the company emphasizes GDPR compliance and data protection, aligning with European regulations.

Security posture

The security maturity level of WonderPush is moderate to good. The site uses HTTPS and claims GDPR compliance, with open source SDKs to ensure minimal data collection. However, the lack of explicit security headers, absence of published privacy and cookie policies in the accessible content, and no visible incident response or vulnerability disclosure mechanisms indicate gaps in security transparency and readiness. The missing WHOIS data for the domain raises concerns about domain registration legitimacy, which could impact trust. Data hosting on Google Cloud with European data residency is a positive indicator for compliance. Overall, while the site shows awareness of security and privacy, improvements in policy publication, security headers, and incident response communication are recommended to enhance security culture and readiness.

Recommendations

  1. Publish clear and accessible privacy and cookie policies on the website to improve transparency and compliance.
  2. Implement and configure security headers such as Content-Security-Policy, X-Frame-Options, and Strict-Transport-Security to enhance protection against common web attacks.
  3. Establish and publish a vulnerability disclosure policy or security.txt file to facilitate responsible reporting of security issues.
  4. Clarify domain registration details and ensure WHOIS information is accurate and publicly available to improve domain legitimacy trust.
  5. Add explicit contact information for security and data protection officers to improve incident response readiness and user trust.

Technical notes

Notes

The website is built on WordPress using the Divi theme, a widely used and flexible CMS and theme combination. It uses modern web fonts from Google Fonts and includes Matomo analytics for privacy-focused user tracking. The site loads external scripts asynchronously and preloads critical resources for performance. Hosting is claimed to be on Google Cloud, which is a reliable and scalable infrastructure provider. The site is mobile-optimized with responsive design and good accessibility features. However, the absence of detected security headers and incomplete metadata for domain registration are technical risks. The site could benefit from enhanced security configurations and clearer policy documentation to reduce technical debt and improve overall robustness.
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.
