Why mid-sized companies are more concerned about VoIP security than smaller, larger competitors are

I've been reading a press release from tech research firm In-Stat.

The press release offers a couple of tidbits from the newly released $2,995 report,"Trends and Spending Plans for Security Appliances: Are We Ready for VoIP?"

Two big VoIP-related findings in this report:

"Larger, mid-size companies (with 500 to 999 employees) show a higher percentage of concerns about VoIP security than smaller or larger companies;"

"Budgets allocated for new security appliances are significantly higher in companies that have already implemented VoIP."

As to the first point, I'd say that smaller companies may not have the in-house IT and/or networking infrastructure in place that could transcend the "coolness" reputation of VoIP. Larger companies, in turn, may have less concerns because they have the personpower in place to identify, and then implement security-related VoIP solutions.

The second point is kind of a "duh." With VoIP in place, it may be time to implement those security appliance solutions that might just sound a bit theoretical to potential VoIP customers.
