Iain Hume and Jon Parkin both threatened for North End but keeper Andy Lonergan had to be at his best to keep out Steve Morison amongst others to ensure the scores remained level.
Jackett said: "I am frustrated, we got behind the Preston defence on numerous occasions so to come away with no goals is disappointing. There were some good saves from their goalkeeper and wayward finishing from ourselves. We didn't capitalise from the dangerous positions we got into, but for the away side it's a good point.
"Initially, we are frustrated because I thought it was a winning performance. But from Middlesbrough and Preston away you would take four points. It was a performance full of heart and we have some big hearts in the dressing room and we move on to our home games."
He added: "Liam Trotter went off with a hamstring - he was adamant he felt it and had to come off.
"We hope it is not too long because he is a key player for us, but having said that (Nadjim) Abdou came on and played well for us. He has been out for a while but he made an impression on the game and I'm pleased for him."
