Cybersecurity, Cloud & Data Privacy Compliance

Cybersecurity and cloud compliance frameworks this CPA practice covers in California

Thirty years of practice, twenty of it auditing financial institutions, produced coverage across a specific set of frameworks rather than a generic claim to do "compliance":

• SOC 1 and SOC 2, readiness, gap remediation, and attestation for service organisations
• ISO 27001 / 27002. ISMS design and readiness
• NIST Cybersecurity Framework and NIST 800-53, assessment and control mapping
• FISMA and FedRAMP, readiness for organisations selling into federal agencies
• PCI DSS, scoping, gap assessment and remediation planning
• CCPA and CPRA. California's privacy regime, including consumer rights operations
• GDPR, for US companies with European data subjects
• HIPAA and HITECH, security-rule risk analysis for covered entities and business associates
• CMMC, readiness for defence supply-chain participants

The point of listing them is not breadth for its own sake. It is that these frameworks overlap heavily, and a company chasing three of them separately typically pays for the same control to be documented three times. Mapping once and testing once is the single largest cost reduction available in this pillar.

Why the 101 corridor generates this work

The stretch of the 101 running through Thousand Oaks, Newbury Park, Camarillo and Westlake Village has an unusual concentration of biotech, medical device, financial services and technology companies. Each brings a different compliance obligation. FDA 21 CFR Part 11 and GxP for the life sciences firms, HIPAA for anything touching patient data, GLBA and FFIEC expectations for the financial institutions, SOC 2 for the SaaS companies selling to enterprise buyers.

What these have in common is that the obligation lands on a company that has an IT function but not a compliance function, and a finance function that has never been asked to evidence anything to a third party. The gap is rarely technical. It is that nobody has translated the requirement into a set of controls someone owns.

What a first engagement usually looks like

Most companies arrive with a deadline attached to a commercial event: an enterprise customer has made SOC 2 a condition of renewal, a health system has sent a vendor security questionnaire, an investor has asked what happens to the business if the AWS account is compromised.

The first engagement is therefore almost always a readiness assessment rather than an audit, scope the boundary, inventory what exists, test a sample of controls informally, and produce a gap list with effort and sequence attached. That work typically runs three to five weeks and is the cheapest insurance available, because a gap found during readiness costs a fraction of the same gap found during fieldwork, when the auditor bills for the extra time and a control may need to be re-tested over a fresh observation window.

Automation platforms: useful, not sufficient

Compliance automation tooling genuinely reduces cost, evidence collection and continuous monitoring are better handled by software than by a spreadsheet and a quarterly reminder. Companies using these platforms well reduce total programme cost meaningfully.

What the tooling does not do is make judgments. It does not decide what is in scope. It does not determine whether a compensating control is adequate. It does not tell you that the exception you have documented will draw a qualification. And it does not eliminate the auditor's fee, because someone still has to form and sign an opinion.

Where a client already runs one of these platforms, the engagement works with it. Where a client is choosing one, the honest advice is usually to scope the programme first and select the tool second, the reverse order produces a tool configured against a boundary nobody has agreed.
