Fontana · San Bernardino County, California
IT & WISP Support for CPA Firms in Fontana, CA
Practical IT and Written Information Security Plan (WISP) implementation for accounting firms in Fontana — built to what IRS Pub 4557 and the FTC Safeguards Rule actually require. Bilingual EN/ES.
What does a Fontana, CA CPA firm need under IRS Pub 4557 and the FTC Safeguards Rule?
A written WISP, MFA on every account that touches tax data, encrypted backups, access controls, security awareness training, and documented incident response. The 2023 Safeguards Rule amendments apply to solo practitioners and small firms. We draft the WISP and implement the controls behind it; bilingual EN/ES throughout.
Why a local MSP in Fontana
Fontana's CPA and bookkeeping community largely serves bilingual small-business clients — trades, restaurants, retail, distribution operators across the central IE. The compliance baseline is the same as any CPA firm: FTC Safeguards Rule (revised 2023) requires a WISP, IRS Pub 4557 enumerates the technical safeguards the IRS expects, and PTIN renewal puts the firm's ability to practice on the line. Bilingual support matters operationally — partners and staff get supported in the language they actually work in.

IT in Fontana: the local picture
CPA firms in Fontana serve a client base that's heavily bilingual and includes a lot of cash-intensive operators — restaurants, trades, retail, distribution — meaning the firm itself handles a large volume of regulated data in both languages. The FTC Safeguards Rule (16 CFR 314, revised effective June 2023) requires a Written Information Security Plan, a named security officer, MFA on accounts that access customer information, encryption of customer information at rest and in transit, and a documented incident-response capability. IRS Publication 4557 specifies the same expectations in IRS language, and PTIN registration puts enforcement teeth behind both.
Practically, the technical work for a Fontana CPA firm includes: MFA on the IRS e-services account and every Microsoft 365 mailbox, encryption on every workstation and laptop, encrypted file transfer for client documents, audit logging retained per malpractice-carrier expectations, and real backup behind the tax-prep software database with quarterly tested restores. The WISP itself is a written document naming the security officer, describing the customer information being protected, listing the safeguards, and outlining the incident-response procedure. We write the first version with you (in either language), then keep it current as part of standard managed IT.
Why local matters for a Fontana CPA firm: tax-season deadlines don't move, partners and clients are often bilingual, and a remote help-desk operating in English-only loses tickets in translation. We come to your Sierra Avenue or Citrus Avenue office, walk through the stack with the partner, and produce the documentation an IRS reviewer or insurance carrier asks for. Free 30-minute call — bring your current WISP if you have one.
