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

3 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 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

Pusher operates a SaaS business model focused on realtime communication APIs and push notifications, targeting developers and enterprises. Their competitive advantage lies in their scalable, reliable infrastructure and developer-friendly tools. The company benefits from strong partnerships and endorsements from major clients like Buffer, GitHub, and The Washington Post. Revenue streams likely include subscription plans for their Channels and Beams products. The parent company MessageBird provides additional market leverage and resources. Growth indicators include extensive SDK support and active developer engagement through tutorials and documentation. The partnership ecosystem is robust, integrating with analytics and marketing platforms to enhance service offerings.

Security posture

Pusher exhibits a solid security posture with HTTPS enforced and domain registration protections that prevent unauthorized changes. However, the lack of DNSSEC and absence of explicit security policies or incident response information on the website are gaps that could be addressed. No vulnerabilities or exposed sensitive data were detected in the provided content. The use of reputable hosting and analytics providers adds to the security maturity. Compliance with GDPR and other privacy regulations is unclear due to missing privacy and cookie policies. Incident response readiness and security culture indicators are not publicly documented, suggesting an area for transparency improvement.

Recommendations

  1. Enable DNSSEC on the domain to enhance DNS security and prevent spoofing.
  2. Publish comprehensive privacy and cookie policies with clear GDPR compliance statements.
  3. Add a dedicated security policy page detailing frameworks, certifications, and incident response procedures.
  4. Implement and document security headers such as Content-Security-Policy and X-Frame-Options.
  5. Provide clear contact channels for security incidents, including security@ or abuse@ email addresses.

Technical notes

Notes

The website is built using modern web technologies including React and Gatsby, ensuring fast performance and good mobile optimization. Hosting is provided via AWS, inferred from DNS servers, which supports scalability and reliability. The site integrates multiple analytics and marketing tools such as HubSpot, Google Tag Manager, and Segment, enabling effective user tracking and marketing automation. The content is well-structured with SEO-friendly meta tags and Open Graph data. Accessibility features are present but could be further enhanced. No technical debt or legacy technology indicators were found. Opportunities exist to improve security configurations and privacy compliance disclosures.
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.
