## Our take

What our shortlists say about each one.

### [Broadcom Symantec Email Security](https://cybersectools.com/tools/broadcom-symantec-email-security)

Best for: Large companies needing cloud and on-premises mail

It makes the list because it offers both a cloud service and an on-premises Messaging Gateway, as a virtual or physical appliance, which suits large companies that still run their own mail servers. Browser isolation opens risky links away from the user's machine. If you plan to move mail to the cloud, ask how your policies carry over from the gateway to the cloud service.

### [Palo Alto Networks Unit 42 Managed XSIAM](https://cybersectools.com/tools/palo-alto-networks-unit-42-managed-xsiam)

Best for: Large companies standardizing on Cortex XSIAM

Unit 42 Managed XSIAM is on the list for scope, because one service covers endpoints, cloud, network, identity and email with threat hunting and custom detection engineering. It fits mid-market and enterprise companies that are standardizing on Cortex XSIAM, since the service runs on that platform. Weigh that commitment before you sign, because leaving the service also means leaving the platform.
