Social Maneuvering can be used here. p194 of the God Machine Chronicle

Hard Leverage represents threats, drugging, intimidation, blackmail, kidnapping, or other heavy-handed forms of coercion. It drives home the urgency required to force open a character’s Doors.

Hard Leverage that requires the character to suffer a breaking point removes one Door (if the modifier to the roll — not considering the character’s breaking points — is greater than –2) or two Doors (if the modifier is –3 or less).

The example mentions threatening someone and shooting them in the leg. Torture is an automatic -3 modifier.

The only problem I see with this is hostile responses are supposed to make it stop working. You might just rule that Hard Leverage always works. Alternatively you might modify what Impression means, a good Impression might mean that they're terrified and willing to spill their guts (metaphorically).

you could also use the Interrogation mechanic from the Original Core book p81

Interrogation Dice Pool: Wits + Intimidation + equipment (interrogator) versus Stamina + Resolve (subject)

Action: Extended and contested (the task demands a number of successes equal to the subject’s Willpower; each roll represents one hour of interrogation)

Interrogation involves wearing down a subject’s resistance until he or she is incapable of concealing information. It’s an extended and contested process. Make Wits

• Intimidation + equipment rolls for the interrogator. Roll Stamina + Resolve for the subject. The number of successes that each participant seeks is equal to his opponent’s Willpower dots. Thus, if an interrogator has 5 Willpower and his subject has 3, the interrogator wins if he accumulates three successes first, and the subject wins if he accumulates five successes first. The winner breaks the opponent’s will to continue asking questions or to resist any longer. The interrogator’s roll can be modified by equipment such as torture instruments. If the subject is allowed sleep between interview sessions, rolls are made for him normally. If he’s denied normal sleep, he suffers a cumulative -1 penalty for each night of sleep that he misses. Thus, he’s at -1 after the first night, -2 after the second, and so on.

p107 God Machine Chronicle

Intimidation: The captured soldier from the other side of the lines knows where the Flag is…but he’s only going to talk if you convince him it’s worth his while or that you’ll kill him (or worse) if he doesn’t. Roll Strength + Intimidation to scare him into talking painfully, or Manipulation + Intimidation to do it by intimation. Torture, by the way, is almost always a breaking point.

you could also use the Interrogation mechanic from the Original Core book p81, the skills chapter did not undergo heavy modification, though you might consider applying a condition for sleep deprivation.
