Surfly’s Interaction Middleware sits in between a user’s browser and the webpage they’re visiting. It receives all the content that makes up the page and temporarily replicates it, giving you the ability to then share it with multiple participants (as seen in the animation below), while layering collaborative features on top of it (co-browsing, screen sharing, video chat, annotations, etc.), or even transform the entire experience, all without changing the original code.

Build your product on top of Surfly
We enable you to build new solutions on top of external applications. The core of our technology is our proxy solution consisting of an HTTP/WS network proxy and the in-browser JS/DOM sandbox.
This allows us to intercept all the inputs and outputs of any web application. By defining what happens in those interception points you can completely change your own application or any third party solution.
Expand the technological scope of your product
With Surfly’s Interaction Middleware, you can add functionalities to any platform or application without changing the application itself. You can embed non-embeddable content, such as third-party applications, or maybe you want to inject custom Javascript code into web pages and build a ‘web-plugin’ that wouldn’t need any software installations on the client’s side.
The options are endless! Check out our technical blog to see what we are working on.


Enable secure interactions
Whether you use Surfly for co-browsing, our proxy solution, or our JS/DOM sandbox, all data flows through our servers through secure SHA-256 SSL encrypted connections. No session data is ever stored.
Additionally, we provide different options for deployment: public cloud, private cloud and on premise. Find out more in our Surfly Security and Compliance Center.

Surfly employs TLS 1.3 transport security, 256bit SSL encryption, full audit log features, and masking of sensitive data to ensure you stay secure and compliant in all your interactions. We are HIPAA, GDPR, ISO 27001, AICPA SOC, and PCI DSS compliant.
