Debutant Andy Keogh rescued the under-fire Tangerines as he scored a last-gasp leveller after Jamaal Lascelles had earlier scored minutes before the break for the visitors.
The Seasiders' season is in tatters following a run of 13 matches without a win in all competitions but Ferguson was delighted with the response of his team as they dug deep and the former Rangers midfielder has challenged them to build on Saturday's result.
"I've never doubted their attitude and obviously I'm proud of what they have done but what pleased me more than anything is they proved what they've got today against a very good Nottingham Forest," he said.
"I've got to be positive from the sidelines. We just needed that break but the goal was a really good goal. Great cross in and Andy Keogh was in the right place with the header.
"I wouldn't be sat here if I didn't believe a win was coming. I believe with the group of players now that the chairman has let me bring in that it's not far away.
"I've had a full week with a full squad and it's given me time to put into practice what style and what formation I want to play.
"They've taken everything on board this week. The training is fantastic, the attitude is great and all they need to do now is bring it here on a Saturday at 3 o'clock and they've done that.
"My main concern is just start winning games. I said to them after the game that's the performance I'm expecting now.
"I know you can do it. There's no hiding place now. I've never doubted their attitude and commitment. It was just their quality and their confidence and that came out in the second half which really pleased me."
Forest took the lead on the stroke of half-time as an Andy Reid free-kick from the left was met by Lascelles who poked low to the right of Matt Gilks.
But the home side saw their pressure tell on 85 minutes as Jack Robinson broke down the left and crossed to the far post where Keogh nodded back across goal into the net.
Forest boss Billy Davies said: "It's a fair result probably. We had the first half, they had the second half.
"Conditions played a huge part on the way the game was played. Very windy, very wet, the pitch was bobbly and soggy.
"I think it was very much a case of long ball rather than football. I've came to this club with very strong teams and picked up nothing.
"I think they're in the wrong position with the teamsheets that they can put out and the players they've got I think they're in the wrong position. This we could look back on and realise that this is a very valuable point.
"I can organise a team. I can change the tactics and I can change the structure but the one thing we've got to do is recognise what is required going into the minutes of late games.
"I think the wind made us go too deep. You've got to give Blackpool credit for the second half.
"All in all, it was a fair result. It was a very good away point. Fifteen games undefeated. And we now look forward to the next match."
