What is the Barracuda Web Gateway 210?

Created for the likes of small offices and the need for a compact form factor, the 210 delivers ample Barracuda computer security you can rely on. While it doesn’t include SSL inspection like the 310, it still packs a decent punch on its own.

  • Throughput: Up to 10 Mbps
  • Concurrent Users: 25 to 100
  • Form Factor: Desktop unit
  • Ethernet Bridge: Not included
  • SSL Inspection: Not included
210

It might seem relatively simple, but that’s also part of the point with this model. You’ll find that the 210 is more than enough for many smaller organizations. However, it’s more lightweight than the 310, and deployment is a bit easier with the desktop compatibility.

What is the Barracuda Security Gateway 310?

If you’re looking for something that carries a bit more strength, then the 310 gateway would be the next step up. This particular model is aimed at larger offices and medium-sized organizations alike. For starters, this can be seen in the cap on concurrent users, which is quite a bit more than the 210.

Here’s how the Barracuda Security Gateway compares at a glance:

  • Throughput: Up to 150 Mbps
  • Concurrent Users: 100 to 400
  • Form Factor: 1U Mini rackmount
