Archer AX73 has switched support from HomeCare to HomeShield. HomeCare launched first and is powered by Trend Micro, you can find more details here. HomeShield launched in 2021 if I remember that correctly and is powered by Avira, its features are discussed here.

Both HomeCare and HomeShield do offer fairly comparable features, and HomeSheild is more geared toward an IoT environment and also is a subscription-based service, it has more advanced and powerful user functionality with more detailed reporting. This is where the value for the subscription really comes in. Also, it features a network scanner to ensure your network is protected. These functions are not available in HomeCare.
