VPN for multiple device protection – What’s the best option for securing my smart home and personal devices simultaneously?

I have a variety of smart devices, including IoT gadgets, laptops, and mobile devices, all connected in my home. I’m looking for a VPN that can secure all these devices simultaneously without compromising the performance of any of them. Ideally, I need a service that works well with my router, so all devices are protected without needing individual apps. I’m also concerned about speed for my streaming services and ensuring no device is left vulnerable. Any suggestions for a VPN that works seamlessly with a large network of devices and provides robust protection?
