Which two secure deployment models are appropriate for a Qlik Sense environment planned to scale up to 5000 users?

Creating a VPN to enable external access while deploying Qlik Sense in a DMZ with a reverse proxy is an effective secure deployment model for scaling to a large user base, such as 5000 users. This approach ensures that external users can access the Qlik Sense applications securely over the internet. A reverse proxy acts as an intermediary between users and the Qlik Sense server, providing an additional layer of security by obscuring the internal network.

The implementation of a VPN further secures the communications, allowing only users with appropriate credentials to connect to the corporate environment, while also ensuring that data in transit is encrypted. This model is especially important for organizations that handle sensitive data and need to adhere to strict security protocols. Moreover, a DMZ is often used to protect an internal network from potential attacks that may come from external user access.

The other options present challenges that may not align with the requirements for scalability and secure access. Deploying Qlik Sense exclusively within the corporate network bypasses the necessary external access for remote users, limiting scalability. Configuring an offline version may not meet the needs of a large and active user base, as offline access can restrict collaboration and real-time data usage.
