Cisco is almost synonymous with big business in the network infrastructure market but recently they have really been working to make themselves more friendly to the SMB market.
Here is a good article about that:
Working at a consulting company that is a Cisco partner and has a large focus on small business I find that there are a lot of great Cisco products in the price range my client’s look for.
The ASA 5505 for example is a great little firewall with a lot of good features and price was is right on the mark and often cheaper then equivalent Watchguard and Sonicwall products. As well the UC500 Integrated services voip router is a great solution for a small business who wants a voice solution with a reasonable cost, particularly if they need a primary router/firewall and/or small wireless solution in any case.
