What Is SOC 2 Compliance, and Why Does It Matter for Third-Party Providers to Financial Services Firms?
By Travis DeForge, Abacus · Published October 29, 2026 · Updated October 29, 2026
Short answer: SOC 2 is an independent examination, performed by a licensed CPA firm, of how a service organization designs and operates controls over security and related criteria. A SOC 2 Type II report tests whether those controls actually worked across a review period, usually three to twelve months. For financial services firms, a vendor’s SOC 2 Type II report is the standard evidence used to satisfy due diligence, allocator questionnaires, and regulatory examination requests.
SOC 2 is not a certification and not a government program. It is an attestation: a CPA firm examines a service organization’s controls and issues an opinion. That distinction matters when a firm is comparing two managed service providers.
What are the SOC 2 Trust Services Criteria?
The Trust Services Criteria are the AICPA’s framework for SOC 2 examinations, organized into five categories: Security, Availability, Processing Integrity, Confidentiality, and Privacy. Security, known as the common criteria, is included in every SOC 2 examination. The other four are optional and are included only when the service organization elects them.
Security covers protection of the system against unauthorized access, use, and modification. Availability covers whether the system is available for operation as committed. Processing Integrity covers whether processing is complete, valid, accurate, and timely. Confidentiality covers information designated as confidential. Privacy covers personal information specifically.
The category selection is the most important thing a reader checks first. A vendor that hosts a firm’s trade reconciliation data and holds a Security-only SOC 2 report has not been examined on availability or processing integrity, even though both may matter more to the firm than security alone.
The criteria come from the AICPA Trust Services Criteria, TSP section 100, issued in 2017 with revised points of focus published in 2022.
What is the difference between SOC 2 Type I and Type II?
A SOC 2 Type I report examines whether controls are suitably designed at a single point in time. A SOC 2 Type II report examines both design and operating effectiveness across a defined review period. Type I answers “were the right controls in place on that date.” Type II answers “did those controls actually work for the past several months.”
| SOC 2 Type I | SOC 2 Type II | |
|---|---|---|
| What is tested | Design of controls | Design and operating effectiveness |
| Time covered | A single point in time | A review period, typically 3 to 12 months |
| Evidence sampled | Control descriptions and configurations | Samples of control activity across the period |
| Typical use | First-time reporting, interim evidence | Ongoing vendor due diligence |
| What a gap looks like | A control is missing or poorly designed | A control existed but failed during the period |
| Accepted for most FS due diligence | Rarely, and usually only as a bridge | Yes, this is the expected report |
Most financial services firms and their allocators will accept only a Type II. A Type I is commonly issued by an organization completing its first examination and is treated as a temporary substitute while the Type II review period runs.
Why do financial services firms ask vendors for SOC 2 reports?
Financial services firms request SOC 2 reports because their own regulatory obligations extend to the third-party vendors that hold their data. The SEC, FINRA, and state regulators expect a firm to supervise third-party service providers, and a SOC 2 Type II report is an artifact that demonstrates the firm did so.
Regulatory pressure on vendor oversight has increased. The SEC’s amendments to Regulation S-P, adopted in May 2024, require covered firms to maintain a written incident response program and to have written policies requiring service providers to notify the firm of a breach within 72 hours. Compliance enforcement began December 3, 2025 for larger entities and June 3, 2026 for smaller entities.
Allocator and investor diligence is the second driver. Institutional investors, fund administrators, and prime brokers routinely request a manager’s vendor SOC 2 reports as part of operational due diligence, and a missing report can stall an allocation.
The financial exposure behind the paperwork is real. IBM’s Cost of a Data Breach Report 2026 put the average financial services breach cost at $6.29 million, up 13% year over year and the second-highest of any industry. Verizon’s 2026 Data Breach Investigations Report found that 48% of breaches involved a third party, a 60% increase over the prior year.
How long should you expect a provider’s SOC 2 process to take?
A first SOC 2 Type II engagement generally takes six to twelve months or more end to end. That matters when you are evaluating a provider, because it tells you whether a vendor claiming SOC 2 compliance has actually completed the work or is still partway through it.
The engagement runs in three phases: readiness and remediation, the observation period during which controls must operate, and fieldwork and reporting. The observation period is the part that cannot be compressed. A Type II report covers a stated review period, and the auditor samples control activity across it. A provider that wants a twelve-month report waits twelve months.
Annual renewals move faster, because the control environment already exists and evidence collection has become routine. The long timeline belongs almost entirely to the first cycle.
The practical question to ask a provider is not whether they are “SOC 2 compliant” but which report they hold, what period it covers, and whether the periods run consecutively. A provider mid-way through a first observation period has started the work. It has not finished it.
What does your provider’s SOC 2 investment tell you about their commitment?
A SOC 2 Type II examination costs a provider real money and a year of work, which is why the report is worth more as a signal than a questionnaire response. A provider that holds one has chosen to be measured against a fixed standard by an outside auditor who has no incentive to be generous.
The investment falls into three buckets. Auditor fees cover the examination itself, performed by a licensed CPA firm. Readiness and remediation work covers everything the provider had to fix before it could be examined, which is usually the largest share and often means deploying multi-factor authentication, building a logging pipeline, writing and approving policies, and testing restores. Ongoing evidence collection covers the continuous work of proving, month after month, that the controls still operate.
That third bucket is the one that separates a serious commitment from a one-off exercise. A SOC 2 Type II report is not a certificate a provider earns once. It requires the control environment to keep running, and to be re-examined every year, with the evidence to prove it.
For a financial services firm evaluating providers, that is the useful read. The question is not what SOC 2 cost the vendor. It is whether the vendor has built security into how it operates, or treated it as a sales document.
What should you look for in a SOC 2 report from an IT provider?
Read the report, not the badge. A SOC 2 Type II report runs dozens of pages, and the parts that matter to a financial services firm are the scope, the review period, the auditor’s opinion, the exceptions, and the complementary user entity controls.
Six things to check in a vendor’s SOC 2 Type II report:
The review period. Confirm it is current and continuous with the prior report. A gap between periods is a gap in evidence.
The Trust Services Criteria in scope. Security only, or Security plus Availability and Confidentiality? Match the categories to what the vendor does for your firm.
The systems in scope. A report covering one hosted platform says nothing about the vendor’s corporate environment, where support staff hold administrative credentials.
The opinion. An unqualified opinion is clean. A qualified opinion means the auditor identified something material.
Exceptions and management responses. Exceptions are normal. What matters is their severity, their pattern across periods, and what management did.
Complementary user entity controls. These are the controls the report assumes your firm operates. If your firm does not operate them, the vendor’s controls do not work as described.
What do financial services firms get wrong about SOC 2?
The most common error is treating the existence of a SOC 2 report as the answer rather than reading what it says. A SOC 2 report with a narrow scope, a stale review period, or repeated exceptions is weaker evidence than a thorough vendor questionnaire, but it clears procurement because a report exists.
Four other mistakes appear regularly in vendor due diligence at financial services firms:
Accepting a Type I as equivalent. A Type I tests design at a moment in time and does not test whether controls operated. Treat it as a bridge, not a conclusion.
Ignoring complementary user entity controls. These are obligations transferred to the firm. Unread, they become unmanaged gaps.
Assuming SOC 2 covers regulatory compliance. SOC 2 is an attestation against the AICPA Trust Services Criteria. It does not establish compliance with Regulation S-P, FINRA rules, or 23 NYCRR 500, though the underlying controls often overlap.
Collecting reports without a review process. A report filed and never read produces documentation, not oversight. Regulators ask what the firm did with it.
The practical fix is a short, written vendor review: who reads the report, what they check, what triggers escalation, and where the conclusion is recorded.

Frequently asked questions
No. Neither the SEC nor FINRA requires a SOC 2 report by rule. Both expect firms to supervise third-party service providers and to maintain reasonable safeguards for customer information, and a SOC 2 Type II report is the evidence most firms use to demonstrate that oversight. The report is a market and examination expectation rather than a regulatory mandate.
Annually in practice. A SOC 2 Type II report covers a stated review period, and firms expect consecutive periods with no gaps between them. A report whose period ended more than twelve months ago is generally treated as stale during due diligence. Vendors often issue a bridge letter to cover the interval between the end of a review period and the next report.
SOC 1 addresses controls relevant to a client’s financial reporting, which matters for fund administrators and transfer agents. SOC 2 addresses security and the related Trust Services Criteria and is restricted-use, shared under a nondisclosure agreement. SOC 3 covers the same subject matter as SOC 2 but produces a short, general-use summary suitable for public posting, without the detailed testing results.
No. A vendor’s SOC 2 report covers the vendor’s control environment, not the firm’s. A firm remains responsible for its own written information security program, incident response plan, and supervision of the vendor relationship. The SOC 2 report is an input to the firm’s risk assessment, including the complementary user entity controls the firm must operate itself.
