The NSW Teachers Credit Union (TCU) has reduced network downtime and freed-up IT resources by replacing its in-house anti-spam software with a hosted solution.
TCU is on of Australia's biggest credit unions with 320 staff managing $1.8 billion in assets from more than 147,000 members across NSW, the ACT and the Northern Territory.
TCU network administrator Peter Smee said spam, spyware and viruses were blocking network traffic and tying-up IT staff with unnecessary maintenance and software upgrades.
"We had an internal system to control spam and spyware however we were still seeing a high level of spam infiltrate our systems," Smee said.
"It was a growing problem which was increasingly time-consuming and difficult to manage [and] we needed to improve the quality of our e-mail management processes.
"Internal appliances [and] software-based solutions quite often required internal changes, regular technology upgrades, integration of new products, and post-implementation changes."
Smee said more than 80 per cent of e-mails were spam which regularly carried malicious attachments.
He said the TCU needed to replace its anti-spam solutions because it could not afford to buy more software and appliances to build its security stack.
The TCU purchased a hosted gateway solution from Websense to block incoming spam and moderate content filters.
Smee said inbound mail has dropped by 80 per cent which has freed network resources and reduced IT network management.
