Sony has thanked publishing and development partners for support during the PSN downtime, which saw its PlayStation online services closed for over three weeks.
Rob Dyer, senior vice president of publisher relations, said the company owed publishers for their patience while the company was hacked and over 100 million user accounts were compromised.
"We know we owe a great deal to valued partners like you for your patience and support during this difficult time," wrote Dyer in a letter reprinted on IndustryGamers.
"With your continued partnership, PSN will move forward stronger, smarter and better than ever."
Dyer also detailed some of the measures the company is taking to make amends with customers, such as offering free games and free security protection.
Sony is offering two games free to PlayStation 3 users, including LittleBigPlanet, inFamous, WipeOut HD, Ratchet & Clank: Quest for Booty and Dead Nation. PSP owners get a choice of LittleBigPlanet, ModNation, Pursuit Force and Killzone Liberation.
The company is also offering 30 days free membership to the PlayStation Plus service and 60 days free subscription to those that already subscribe.
Subscribers to Music Unlimited also get 30 days free subscription and there will be a deal for PlayStation Home users as well.
While multiplayer gaming and other services such as Qriocity are back online, the PlayStation Store is still not live, leaving Sony and its partners unable to sell virtual goods and games across the PlayStation Network.
