Priority findings

1 finding rated critical or high. Fix these first.

  1. 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

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

  • Security headers: did not complete in this scan.
  • GDPR outside view: did not complete in this scan.
  • 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 providing hosted realtime APIs (Channels) and push notification services (Beams). Its target customers are developers and businesses needing realtime features such as live dashboards, notifications, geotracking, and chat. The company benefits from a strong partnership ecosystem, including its parent company MessageBird, and showcases endorsements from reputable clients like GitHub, The Washington Post, and Mailchimp. The business demonstrates growth potential through extensive SDK support and developer resources. Revenue streams likely include subscription plans for API usage and push notification services. The company maintains a developer-centric approach with comprehensive documentation and tutorials, enhancing customer adoption and retention.

Security posture

The website enforces HTTPS and has domain status protections that prevent unauthorized domain changes, indicating good domain security management. However, DNSSEC is not enabled, which is a recommended best practice for DNS security. No explicit security headers were detected in the provided content, suggesting an opportunity to enhance HTTP security headers such as Content-Security-Policy and X-Frame-Options. The absence of published security policies and incident response information limits transparency and preparedness visibility. No vulnerabilities or exposed sensitive data were found in the analysis. Overall, the security posture is good but could be improved with additional published policies and DNS security enhancements.

Recommendations

  1. Enable DNSSEC on the domain to improve DNS integrity and security.
  2. Publish a comprehensive privacy policy and cookie policy with GDPR compliance details.
  3. Add explicit security and incident response policies accessible on the website.
  4. Implement and configure security HTTP headers to protect against common web vulnerabilities.
  5. Provide clear contact information including security contact channels to improve trust and incident handling.

Technical notes

Notes

The website is built using modern web technologies including Gatsby and React, ensuring fast performance and good mobile optimization. Hosting is managed via AWS infrastructure as indicated by DNS nameservers. The site integrates multiple analytics and marketing tools such as HubSpot, Segment, and Google Tag Manager, enabling detailed user behavior tracking and marketing automation. The content is well-structured with extensive developer documentation and code examples supporting multiple programming languages. Accessibility and SEO optimizations are good, contributing to a positive user experience. There is no detected CMS, indicating a custom-built static site approach. Technical risks are minimal but include the lack of DNSSEC and security headers which could be addressed to further harden the site.
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.
