SOC 2 Readiness for Martech & Adtech Platforms
When an agency holdco or brand asks for a SOC 2 report, a martech platform faces a scoping decision as much as a compliance one: pursue the attestation, and around which systems. Our readiness work scopes SOC 2 to what actually handles client audience data — bid-stream infrastructure, the CDP, the data warehouse — rather than auditing an entire company as if it were a generic SaaS product with none of this platform's data-sharing complexity.

What you're protecting
What belongs inside SOC 2 scope here
The systems worth including are the ones a client's own compliance team is actually worried about.
Bid-stream and audience-matching infrastructure
The services that receive, process and forward identifiers and segments, since this is where a client's data is most exposed once it leaves their own systems.
CDP and data-warehouse access controls
Who can query, export or administer the systems holding audience data, and how that access is reviewed and revoked.
Sub-processor and vendor management
The process for evaluating and monitoring downstream platforms and data suppliers, a control area clients increasingly expect to see documented.
Encryption and logging around identifiers
How pseudonymous identifiers and hashed emails are protected in transit and at rest, and whether access to them is auditable after the fact.
Regulatory map
What SOC 2 is measured against, and why it matters here
SOC 2 is not a statute, but it has become the de facto contract requirement for this industry.
AICPA's trust services criteria
SOC 2 evaluates controls against defined criteria, most commonly security, and increasingly confidentiality and privacy for platforms handling client customer data.
Agency holdco and brand procurement demand
Larger agency networks and enterprise brands increasingly list SOC 2 as a baseline expectation for martech vendors handling their customer data, independent of any regulator.
Overlap with SIG and CAIQ
A SOC 2 report often supplements, rather than replaces, the questionnaire-based reviews the same clients also require, so the two should be scoped together.
PIPEDA's accountability principle
Documented, auditable safeguards support the accountability obligations organizations already carry for personal information, giving SOC 2 readiness value beyond the report itself.
What goes wrong
What happens when SOC 2 scope or readiness is wrong
The cost of getting this wrong shows up as wasted spend or a stalled deal, not a security incident.
A lost or stalled enterprise deal
A brand or holdco that requires SOC 2 as a condition of onboarding will not wait indefinitely for a report that was never scoped, or never started.
Scope that covers the wrong systems
Auditing corporate IT while leaving the bid-stream and CDP infrastructure out of scope produces a report that fails to answer the question a martech client is actually asking.
Evidence gaps discovered mid-audit
Sub-processor tracking, access reviews and retention evidence are common gaps in data-heavy platforms, and finding them during the observation period is far more expensive than finding them in readiness.
A Type I pursued when a Type II was actually required
Some clients specifically require the longer observation period a Type II report provides, and starting with a Type I when that was never going to satisfy the requirement wastes a cycle.
Our soc 2 for martech & adtech platforms
What our SOC 2 readiness work includes
Preparation aimed at the systems and evidence a martech-specific audit actually needs, not a generic checklist.
High-level gap review
An assessment of current practices against the trust services criteria, scoped specifically to bid-stream, CDP and warehouse systems.
Documentation guidance
Support organizing access-control policies, sub-processor records and incident procedures into audit-ready form.
Control consideration support
Guidance on which controls matter most for a platform moving audience data through many downstream partners, rather than a one-size list.
Internal review and feedback
A pass through your evidence before the formal observation period begins, catching gaps while there is still time to close them.
Ongoing support through the audit cycle
Light-touch guidance from scoping through Type I or the Type II observation window, keeping your team aligned as readiness activities progress.
How the engagement runs
How we scope and run readiness
Starting with the decision of whether, and around what, SOC 2 makes sense.
Step 1
Decide whether SOC 2 is the right answer
Confirm what clients are actually asking for, since a SIG or CAIQ response may satisfy the immediate need while SOC 2 is prepared in parallel.
Step 2
Scope the audit boundary
Define which systems, teams and data flows sit inside scope, prioritizing bid-stream, CDP and warehouse infrastructure over unrelated corporate systems.
Step 3
Close the gaps
Remediate the control and documentation gaps the review surfaces, in priority order, before the observation period starts.
Step 4
Support through the observation period
Stay engaged as evidence accumulates for a Type I or Type II report, coordinating with your chosen auditor, whose fees are separate from readiness work.
What it costs
Readiness cost drivers for a martech platform
Spend depends on scope breadth, how mature your access governance and sub-processor documentation already are, whether you pursue a Type I first or go straight into a Type II observation period, and how many remediation items the gap review surfaces. Auditor fees are separate from readiness work and worth budgeting for early.
Platforms already running our vCISO or Virtual Privacy Office engagements start well ahead, since much of the access-control and documentation work already exists. Either way, we scope readiness against what your actual clients are asking for and quote accordingly.
Martech & Adtech Platforms: SOC 2 questions, answered
It typically covers the security criterion at minimum, scoped to the infrastructure processing client audience data, such as bid-stream services, CDP access and the data warehouse. Platforms that hold sensitive segment data or serve privacy-conscious brands often extend scope to include the confidentiality or privacy criteria as well, depending on what their largest clients are asking for.
Increasingly, yes, particularly from larger agency holding companies and enterprise brand clients, though smaller agencies more often rely on a completed SIG or CAIQ questionnaire instead. Many martech vendors end up preparing both, since the underlying evidence, access controls, sub-processor management and incident procedures, largely overlaps.
A Type I confirms controls are designed correctly at a point in time and can satisfy an early-stage client request, but many enterprise procurement teams specifically require a Type II, which demonstrates the controls operated effectively over a period of months. Confirming which your target clients need before committing to a timeline avoids preparing the wrong report.
Readiness itself usually runs a few months depending on how many gaps the initial review finds, and a Type II report additionally requires an observation period, commonly three to twelve months, during which the audited controls must operate consistently before the auditor can report on them.
Yes, and it often should. A vCISO already owns the access-governance and control decisions that SOC 2 evidence depends on, so readiness work layered on top of an existing vCISO engagement typically moves faster than starting from a blank documentation set.
No. SOC 2 evaluates security and, where scoped, confidentiality or privacy controls, but it does not assess CASL consent record-keeping or Law 25's default-off tracking requirements. Platforms typically need SOC 2 readiness and dedicated privacy work, such as policy development or a Virtual Privacy Office retainer, running in parallel to cover both.
