The council is using the Pinsafe authentication system from Swivel Secure to support secure remote working.
Users have their own Pin and are sent a 10-digit security string each time they wish to gain access to the network via text message or PDA. The security string and Pin are combined to generate a single-use access code.
The council's previous system used physical tokens, which proved to be expensive and time-consuming to operate. It often saw staff without access owing to lost or missing tokens, and replacements added to the council's admin costs.
Pinsafe requires no tokens, meaning network security is cheaper to run, easier to manage and more user-friendly.
Howard Gaskin of Ipswich Borough Council said, "We wanted a solution that would give us flexibility and management control whilst offering tangible cost savings.
"We explored a number of options but PINsafe was the clear winner."
