Neither side was able to make the breakthrough at the Britannia Stadium as the Potters recorded their sixth stalemate of the season.
"We're disappointed. We needed a break but Sunderland have been very strong and were very well set up," Pulis said.
"I thought their keeper was brilliant but it just wasn't our day. I can't remember Asmir Begovic having a save to make."
The point has seen Stoke move up one place to 12th in the Premier League table.
