SOC 2 consultant for US startups on AWS — audit-ready in weeks.

This is the first decision and it is frequently made backwards. A Type 1 report attests that your controls are suitably designed at a single point in time. A Type 2 attests that they operated effectively across an observation window - commonly three to twelve months, with six being a frequent choice for a first report.

Buyers overwhelmingly want Type 2. A Type 1 says you had the right controls on one day; a Type 2 says you ran them. Where Type 1 earns its place is as a checkpoint when a deal is in flight and you need something credible in hand while the observation window runs. It is a milestone, not a destination, and it costs a separate audit fee - so take it when a specific deal justifies it, not by default.

The practical sequence for most startups: close the gaps, start the observation window as soon as the controls are genuinely operating, and go straight to Type 2 unless a customer forces the interim step.

SOC 2 is built on the AICPA Trust Services Criteria: Security, Availability, Processing Integrity, Confidentiality and Privacy. Security - the common criteria - is mandatory. The other four are optional.

Most startups need Security alone for their first report, and adding categories because they sound reassuring is a reliable way to make the engagement longer and more expensive than it needed to be. Add Availability when you have contractual uptime commitments you are willing to be audited against. Add Confidentiality when you handle customer data under specific confidentiality terms that go beyond ordinary security. Processing Integrity matters mainly if you transform data in ways customers rely on being correct - payments, calculations, reporting. Privacy is the heaviest and is usually better served by addressing the applicable privacy law directly.

Ask your prospects what they actually require before scoping. In most cases the answer is a Security-only Type 2, and the deal does not move faster because you added categories nobody asked for.

The criteria are deliberately not prescriptive, which is why teams find them hard to translate. Here is what the evidence requests consistently reduce to on an AWS stack.

Two more that catch people out: policies must exist, be approved, and be acknowledged by staff - auditors check acknowledgement records, not just the documents. And security awareness training with completion evidence is a routine request that takes ten minutes to arrange and derails a week if it starts the day the audit opens.

For an early-stage company already on AWS with reasonable engineering hygiene: two to six weeks of gap remediation, then the observation window, then fieldwork and report issuance. From standing start to a Type 2 report in hand is commonly four to nine months, dominated by the observation window rather than by work.

Costs fall into three buckets that are worth separating when budgeting. The audit firm is a fixed external cost and quotes vary widely for the same scope, so get more than one. Compliance tooling - Vanta, Drata and similar - automates evidence collection and is genuinely useful, though it is not a substitute for the controls themselves; the tool will tell you a control is failing, not implement it. Engineering time is the cost people underestimate, and it is where scope discipline pays: every optional criterion added is more of it.

The most expensive mistake is starting the observation window before the controls are actually operating. Exceptions accumulate, and an exception in a Type 2 report is something you then explain to every prospect who reads it.
