Finance IT

Financial services firms — from solo CPAs to multi-partner advisory practices — operate under a growing stack of compliance obligations. The FTC Safeguards Rule now requires all tax professionals to maintain a Written Information Security Plan, and the expectation is that it reflects real controls, not paper compliance. The Corporate Transparency Act added BOI reporting requirements. State-level financial privacy laws continue to evolve. And through all of it, the underlying cyber threat environment keeps getting harder: deepfake voice and video tools are being deployed in fraud schemes, phishing is more targeted, and supply chain attacks on financial software platforms are increasing.

The stakes of getting IT wrong in financial services are particularly high. Client financial records and personally identifiable information are exactly what attackers want to steal, sell, or encrypt for ransom. System downtime during tax season or quarter-end doesn't just inconvenience clients — it creates filing risk, damages professional relationships, and can trigger regulatory scrutiny. Continuous auditing trends mean regulators increasingly want to see real-time controls and evidence, not a once-a-year attestation that everything was fine.

Sonic Systems works with accounting firms, financial advisors, and financial offices across Southern California to build technology environments that match their compliance obligations and risk profile. We help firms develop WISPs that reflect actual controls, implement the layered security stack that financial regulators expect, and build infrastructure that stays reliable when the deadline pressure is highest. Two decades of serving local businesses means we understand what it takes to operate in a regulated environment — and how to make compliance a manageable part of operations rather than a constant emergency.
