Why Tax Firms Get Attacked First

An accounting firm is a one-stop shop for identity thieves: Social Security numbers, bank accounts, EINs, prior-year returns, and the e-file credentials to impersonate the firm itself. That’s why tax practices are among the most targeted small businesses in America — and why the IRS and FTC now require them to prove they take security seriously. Advanced Networks provides cybersecurity built for accounting firms, combining 24/7 protection with the documentation that regulators, insurers, and clients increasingly demand.

In more than 20 years serving Los Angeles and Orange County, and we include EDR, MDR, MFA, and tested backups on every client. We bring that same track record to CPA firms, tax practices, and bookkeeping companies across LA.

  • Endpoint detection and response (EDR) with 24/7 monitoring
  • Email security with anti-phishing and spoofing protection
  • Multi-factor authentication across all systems holding client data
  • Full-disk and backup encryption

What We Deliver

The Security Program, Layer by Layer

Every control below maps to a Safeguards requirement and an insurer checklist line.

🛡️
Managed detection and response
EDR on every endpoint, 24/7 monitoring, and a security team that investigates and contains threats in minutes — not after the damage is done. See our cybersecurity services in Los Angeles.
✉️
Email security and anti-phishing
Advanced filtering, spoofing protection (SPF/DKIM/DMARC), and banner warnings tuned for the client-impersonation scams tax firms see every spring.
🔐
Multi-factor authentication everywhere
MFA across email, tax software, remote access, and portals — a Safeguards requirement and the single highest-value control against credential theft.
🔒
Encryption and secure file exchange
Full-disk encryption on laptops, encrypted backups, and client portals that keep SSNs out of email. See our data encryption services.
🎓
Security awareness training
Short, regular training and simulated phishing focused on the scams aimed at your staff — because one rushed click in March is all it takes.
💾
Backup and ransomware recovery
Immutable, tested backups and a documented recovery plan, so even a worst-case event doesn’t cost you a season.
The Threats

What’s Aimed at Your Firm

The attacks we intercept for accounting clients every season.

01
Tax-season phishing
Fake IRS notices, spoofed client emails with “revised W-2s,” and payroll-change scams timed to your busiest weeks.
02
Ransomware
That encrypts client files in the one season the firm can least afford downtime.
03
EFIN/PTIN and software-credential theft
Used to file fraudulent returns under your firm’s identity.
04
Business email compromise
Targeting wire instructions and client refund redirects.
05
Data theft
From unencrypted laptops, aging servers, and email attachments full of PII.
06
Vendor risk
Portals, hosting providers, and plugins with access to your client data.

Real Outcomes

Case-Study Snapshots

Anonymized where needed — real LA engagements.

01
The intercepted refund scam
A client’s email was spoofed to redirect a six-figure refund to a fraudster’s account. The firm’s trained staff flagged the change request, verified by phone, and reported it — the exact human firewall our training builds.
02
A WISP that survived scrutiny
After a data-security question from a large client, a CPA firm needed to demonstrate its program within a week. Because controls and documentation were already in place, the response took an afternoon — and the client relationship deepened.
03
Laptop lost, crisis avoided
A senior accountant’s laptop disappeared from a car. Full-disk encryption and remote wipe turned a reportable breach into a hardware replacement.
Frequently Asked Questions

Accounting Security Questions, Answered

What partners ask when the Safeguards letter lands.

Does the FTC Safeguards Rule really apply to my CPA firm?
Yes. Professional tax preparers, CPA firms, and bookkeeping businesses that handle client financial data are covered as “financial institutions” under the rule, regardless of size. Firms with fewer than 5,000 consumer records get limited exemptions from some written requirements, but the core controls still apply.
What is a WISP and do we need one?
A Written Information Security Plan documents how your firm protects client data — and both the FTC and the IRS expect you to have one. We build yours from the controls actually running in your environment.
What happens if our firm suffers a breach?
You’d face client notification obligations under California law, potential FTC exposure, IRS review of your e-file privileges, and insurance scrutiny. Our job is to make that scenario vanishingly unlikely — and fully recoverable if it ever happens.
Can you work with our existing IT provider?
Yes. We can layer managed security on top of an incumbent IT relationship, or handle both as one flat-rate service.
How fast can you get our firm compliant?
Most firms reach a defensible baseline — MFA, EDR, encryption, backups, training scheduled, WISP drafted — within 30 to 60 days of assessment.
Is this included in your managed IT plans?
The core security stack is included in every plan. Firms can also engage us for security and compliance alone. See managed IT for accounting firms.
