Cisco Handles Email Security for a Regional Telecommunications 

Leader 

Panhandle Telephone Cooperative, Inc. (PTCI), dominates its market 

area, providing a full range of telephone, cellular, Internet, and 

television services to commercial and residential customers. With roots 

dating back to the mid-1950s, PTCI has long delivered exceptional 

customer service and advanced product offerings in the dynamic 

communications arena. To maintain its competitive edge, the company 

required an email security so

lution able to stand up to today’s complex 

threats. 

 

 

 

 

 

 

PTCI’s previous security systems failed to meet the demands of increased email traffic volumes, including system 

stability and heightened pressures on network management. Realizing it needed to upgrade its security system, PTCI 

researched Barracuda, Tumbleweed, and Cisco

®

. Based on that review, and the testimonials of satisfied customers, 

the company selected the Cisco IronPort

®

 C-Series Email Security Appliance to provide the stability and security it 

required. 

As PTCI grew, so did the number of email accounts it handled. Today, PTCI has in excess of 11,000 users who 

expect rapid and reliable email service. PTCI had a range of email security requirements. It needed a system that 

could provide maximum throughput of heavy volumes of email without crashing and compromising the integrity of its 

system. The system had to be nonintrusive to customers and easy to manage and maintain, freeing network 

administrators to focus their time and energies where they were needed most. 

Powered by the Cisco IronPort AsyncOS

®

 operating system, Cisco IronPort Email Security Appliances run on a high-

performance MTA platform, which delivers best-in-class protection through preventive and reactive technologies as 

well as the problem-free management. 

“We had to fight with our previous system, 
which constantly crashed and lost 
customer emails. We’ve not had a single 
incident with the Cisco IronPort solution 
since it was installed over a year ago. It’s 
just a great product.
