France rode their luck throughout and kept the scoreline close thanks to a missed penalty from Cesc Fabregas.
Deschamps told reporters that he thinks the point earned against the reigning world champions may prove crucial in the context of the group.
He said: "It was a very good second-half. We created a lot of opportunities, even if at times we looked for passes when we were in a position to strike.
"But there was much suffering from this Spain team in the second half. Seeing their journey and their results at home, we are happy to take a point. It rewards the group because it is not easy."
Giroud's goal ended Spain's 100% start to their World Cup qualification campaign and kept Les Blues unbeaten in their quest to book a place in the Brazilian showpiece in 2014.
