The sides shared 30 shots on goal in an entertaining match in London, but Italy manager Cesare Prandelli will be left rueing an injury to midfielder Riccardo Montolivo, who will miss the World Cup after suffering a broken leg from an Alex Pearce tackle.
His replacement Alberto Aquilani only lasted for half an hour himself, before coming off with a head injury after a clash of heads with Stephen Ward.
Italy's Giuseppe Rossi seemed sharp as he looked to play his way into Prandelli's 23-man squad for Brazil after a season ruined by a knee injury, and Torino striker Ciro Immobile had a couple of chances in the first half that were snuffed out by David Forde.
Ireland goalkeeper Forde's best save was in the fifth minute, flying across his goal to tip over a 35-yard effort from Claudio Marchisio.
The best chance of the second half came with 12 minutes left on the clock, but Ireland substitute Stephen Quinn hit the bar from point-blank range after getting on the end of a James McClean cross, then Aiden McGeady saw his follow-up shot saved by Sirigu.
5' - FIRST HALF-CHANCE: Immobile seems to be the point of the attack with Rossi in the withdrawn role. Claudio Marchisio then breaks and shoots from 35 yards but Forde does well to tip over.
8' - MONTOLIVO IN TROUBLE: Alex Pearce leaves the leg in on Montolivo and this could be a problem for the Italy captain.
21' - IRELAND'S FIRST CHANCE: Pilkington's dipped free-kick is saved well by Sirigu.
33' - SIRIGU SAVES AGAIN: McGeady skips past Paletta to the byline and his cross to Long at the far post is perfect, but Sirigu does well to punch the header clear.
49' - IRELAND PRESS AGAIN: Hoolahan nicks the ball off Motta and sets up Long, but Sirigu does well to save to his left. Pilkington then has a snapshot wide.
65' - CHANCE WASTED: Cassano's wall pass sets up Marchisio but the Juventus midfielder shoots weakly at Forde.
78' - WOODWORK: Quinn hits the bar from McClean's low cross from the left, then Sirigu saves McGeady's follow-up effort. Chance of the game so far.
Are Italy regretting their insistence on playing Ireland? Italy were keen to face Ireland in this friendly, as Martin O'Neill's side play a similar game to their first World Cup opponents England. But was it a risk - Ireland were never going to hold back, even in a seemingly meaningless end-of-season friendly. And so it transpired - Riccardo Montolivo will miss the World Cup after breaking his leg.
