Most companies already have a traditional email security product installed on-premise. Over time, these products can become overwhelmed by continuously increasing spam volume, requiring additional investments - in the form of additional hardware and sometimes licenses - to remain effective. When working with on-premise email security products, IT staff can find themselves bogged down with the daily maintenance required to keep these products up to date. Frequently, IT staff run these products in "Set and forget" mode which means that application maintenance, tuning and troubleshooting can be neglected and spam-blocking effectiveness will decline over time.
