According to the results of a recent survey [PDF] of 500 C-level managers and senior IT professionals from companies with over 1,000 employees in the U.S. and U.K., 56 percent of respondents said system complexity was the leading issue jeapordizing IT security efforts.

The survey, sponsored by Tufin Technologies and conducted by Research Now, also found that almost 90 percent of respondents said coordination of security policy across the entire network is "essential," and 67 percent think security policy management across the network will become more automated over the next few years.

One third of respondents said their company had suffered five or more firewall-related outages in the last 12 months -- 17 percent of financial services companies reported 11 or more outages in the last year. And a quarter of respondents said they've had to redo more than 60 percent of all firewall changes because they weren't implemented correctly the first time.

"This research shows that network security has become too complex to manually manage, especially with the introduction of new technologies such as Cloud, virtualization and IPv6," Tufin co-founder and CTO Reuven Harrison said in a statement. "The key to meeting these challenges is automation and orchestration which will increase IT agility while maintaining security and compliance across the network."
