Benaglio: Switzerland learned lessons of 2010
The Swiss opened their tournament with victory over eventual champions Spain four years ago, before failing to qualify from the group.
Ottmar Hitzfeld's men kicked off the 2014 event with another win on Sunday - beating Ecuador 2-1 - but Benaglio, who was part of the squad in South Africa, is confident of reaching the knockout stages this time around.
"Of course, the atmosphere is good, but I think that everyone who was involved four years ago is wary of what can happen," he is quoted as saying by FIFA.com. "We've learnt our lesson.
"We've already won against a competitor for a spot in the next round, so things already look brighter than at the last World Cup.
"We've learnt our lessons from 2010 and made so much progress. Now it is time to go out there and show what we can do."
Switzerland meet France in Group E on Friday.
