Paul Anderson gave the visitors a 12th-minute lead at Hillsborough, only for Michail Antonio to get the Owls back on level terms two minutes later.
The result left Wednesday still waiting to record their first win of the season and the Tractor Boys without a victory on their travels.
"I'm delighted with a point," he said. "I thought we were excellent in the first half and I think we had to show a different side to us in the second half in terms of defending and being resolute. I thought we were terrific and defended well.
"If we'd scored to make it 2-1 it would have silenced the crowd. Likewise, if they'd scored it would have probably ended 2-1 to them.
"I was delighted with the way we played in the first half and I think in the second half they improved and we had to defend.
"Following Tuesday's result (4-4 draw at Derby) - when we were 3-0 up and then conceded - it showed there was no hangover. It was a one-off, that.
"Everybody keeps asking us when we're going to win away from home. If we keep playing like that, we're going to win away from home. We haven't got the points we've deserved, but I'm not going to stop the way we're playing."
