Up to 2,000 concurrent users at 250 to 400 Mbps of throughput, more than double the 410's user ceiling. It's a good fit for a growing office or a company running several hundred employees on one network.

Yes. Full SSL inspection is standard from the 410 up, and the 610 runs it at a higher throughput ceiling, so decrypting and filtering encrypted traffic doesn't become the constraint as your user count grows.

Yes, it's a 1U Fullsize rackmount appliance, a larger chassis than the 1U Mini used by the 310 and 410 but still a single rack unit, so it doesn't take up meaningfully more rack space to get the extra capacity.

Hot-swap RAID keeps the appliance running through a single drive failure, so content filtering and SSL inspection stay active while you swap in a replacement drive rather than dropping offline.

The 810 and above move into 2U Fullsize chassis with higher throughput and user ceilings, so there's a clear path up if your organization keeps growing.
