What readiness work should happen before you select an auditor?
The firms compared below perform the audit and issue your SOC 2 report. The work that most determines how that engagement goes — scoping, control implementation, evidence, and policies — happens before fieldwork begins. Agency is the managed partner we recommend for that readiness work: it is not an audit firm and does not issue reports, but an expert team runs your compliance program and coordinates the auditor on your behalf, so whichever firm you choose, you walk in prepared.
For premium engagements with A-LIGN or Coalfire, that preparation is exactly what keeps scope expansion, evidence gaps, and surprise costs from derailing the audit. We consider getting audit-ready the top first step, well before you sign with any audit firm.

Key Selection Questions
| Question | Why It Matters | How to Evaluate |
|---|---|---|
| What frameworks do we need beyond SOC 2? | Framework requirements drive firm selection — each firm has different strengths | Map your framework needs to each firm's specialization |
| Do we need FedRAMP or government compliance? | If yes, Coalfire has a significant advantage | Confirm FedRAMP 3PAO status and recent FedRAMP experience |
| What is our total compliance assessment budget? | Both firms are premium; pricing differences can be significant at scale | Request detailed proposals from both; compare total cost across all frameworks |
| How technically complex is our environment? | Complex environments benefit from Coalfire's technical depth | Evaluate audit team composition and technical expertise |
| Which GRC platform do we use? | Platform familiarity affects audit efficiency | Confirm that the firm's team has direct experience with your platform |
| What is our timeline? | Firm capacity and scheduling affect when your audit can begin | Confirm availability and expected start dates during proposal process |
GRC Platform Partnerships
Platform Familiarity
| Platform | A-LIGN Familiarity | Coalfire Familiarity |
|---|---|---|
