Ivory Coast manager Sven Goran Eriksson described the encounter as "tight".
The former England boss explained: "There weren´t many occasions to score, you saw two teams which didn´t want to lose. I thought if one team had won it should have been us, we created more chances than Portugal.
"I was very happy with our discipline and organisation, we were organised for 90 minutes, in the past it wasn´t like that.
"Another plus was Didier coming on to play. He´ll be even fitter for the next game," added Eriksson, who as England manager lost to Portugal on penalties in the 2006 quarter-finals.
Portugal boss Carlos Queiroz said Ivory Coast had proved tricky rivals as he said they had set out to contain Portugal and launch counter attacks.
"What Eriksson wanted us to do was to take risks so we had to prevent Ivory Coast taking advantage of any errors that we might make.
"We had to play intelligently. Our motivation and attitude was clear. Everything is still possible. This is the Group of Death, only two from Brazil, Ivory Coast and Portugal, with respect to North Korea, can move forward."
Portugal captain Cristiano Ronaldo had the best chance to break the stalemate on a crisp winter´s afternoon in the first half when the Real Madrid winger´s 25m shot rattled Boubacar Barry´s left post in the 10th minute.
Barry´s opposite number Eduardo was let off the hook when shortly after Siaka Tiene´s curling long range freekick edged wide.
Another Ivorian, Ismael Tiote, then watched as his effort went over the Portuguese crossbar.
Referee Jorge Larrionda flashed his yellow card at defender Guy Demel for a foul on Ronaldo who in turn was cautioned for his stroppy reaction.
The Ivory Coast, the last of the six teams from Africa to enter the World Cup fray in South Africa, were giving as good as they got against their rivals from Europe ranked third in the world.
The game needed a goal and Salomon Kalou had Eduardo working with his shot on target in the 50th minute as Portugal manager Carlos Queiroz made his first change, replacing Danny with Atletico Madrid forward Simao.
Gone now was the caution that had marked much of the first period as this Group of Death curtain raiser really opened up and Barry had to be at full stretch to get hold of Liedson´s header after some nifty work down the left from Deco.
On 66 minutes Eriksson unleashed Drogba, who came on for his Chelsea teammate Kalou to by far the biggest cheer of the afternoon.
As the rain came down Ronaldo thought he had put the 2006 semi-finalists into the lead but Larrionda had already whistled for a foul by Liedson.
On 80 minutes Ronaldo, who failed to score in any of Portugal´s World Cup qualifiers, sent a 35m freekick edging over Barry´s crossbar.
A Drogba-inspired Ivory Coast had Portugal on the hop in time added on but he miscued his shot and man-of-the-match Ronaldo and co. escaped with a point.
The result left Ghana as the only one of the six African teams playing in this first ever World Cup in Africa to have won their opening first round match.
Group G favourites Brazil take on North Korea later Tuesday.
