HOW MANY OF THESE ARE TRUE IN YOUR FIRM RIGHT NOW?

01 / THE SIGNATURE

You certified on Form W-12, Line 11 — under penalty of perjury — that you maintain a Written Information Security Plan. If a Stakeholder Liaison asked to see it Monday morning, could you produce it? Or did you check a box and pray?

★ 810,000+ PREPARERS SIGN THIS BOX. MOST HAVE NOTHING BEHIND IT.
02 / THE LEAK

How many of your preparers have a personal ChatGPT tab open right now with a client's W-2, SSN, or full 1040 pasted into it? IRC §7216 makes unauthorized disclosure a federal crime. Whose PTIN is on the line — theirs, or yours?

03 / THE GHOSTS

Your seasonal preparers touched taxpayer data on personal laptops, personal email, and personal phones — and three of them are gone now. Could you prove what they accessed and what they walked out with?

04 / THE MASTER KEY

Your EFIN is the master key to every return you file. If it's compromised, the IRS can shut you down mid-season. Is it protected with MFA and active monitoring — or a password you set in 2019?

05 / THE LAWSUIT

When a client's refund gets intercepted or their identity gets cloned, the lawsuit and the board complaint don't land on the hacker. They land on the firm that held the data. Do your controls hold up under discovery?

06 / THE DENIED CLAIM

Your cyber insurance almost certainly requires a documented WISP. After a breach, the carrier audits your security before they pay. No WISP, no payout — even though you paid every premium on time. Have you read that clause?

IF THREE OR MORE OF THESE LANDED — WE SHOULD TALK.

The Ecosystem

FIVE PILLARS. ONE ECOSYSTEM. ZERO COMPETITORS OFFERING ALL FIVE.

01

WISP & Cyber-Liability Defense

Elite Talent Magnet

The profession is short hundreds of thousands of accountants. Give every staffer modern AI tooling and a firm that runs like 2026, not 1996. The good ones choose you — and stay.

The Offboarding Shield

Every staff departure — documented, clean, and defensible.

The Differentiator

THE CONVERSATION NO ONE IN THIS PROFESSION IS HAVING.

Every year, 810,000+ preparers sign Form W-12 and swear — under penalty of perjury — that they protect taxpayer data. Most then go back to a duct-taped tech stack, personal devices, and a WISP template they downloaded once and never implemented. That gap is a federal liability sitting under your own signature. We close it — and we make it provable.

✓A real WISP — built, implemented, and kept current to IRS Pub 4557 & 5708
✓A timestamped evidence file showing what was implemented, reviewed & maintained
✓Staff security-training records — dated and signed for the Pub 4557 requirement
✓Clean, documented offboarding when seasonal preparers leave
✓The file your cyber carrier demands — ready before the breach, not after
✓Your Form W-12 attestation, finally turned from a hope into a fact

Founder · MOSTRO Cybersecurity

A 25-YEAR OPERATOR. THREE REGULATED INDUSTRIES. ONE INEVITABLE CONCLUSION.

Dennis Patino spent 14 years building marketing engines for regulated industries — including financial services — before founding MOSTRO Cybersecurity. He watched, from inside the room, as professionals who hold the most sensitive data in America started pasting it into personal AI tools. As firms ran on duct-taped tech stacks. As people walked out with client data nobody could prove they took.

MOSTRO 1040 is what he built when he realized the firm that survives the next decade isn't the one with the lowest fees — it's the one that can prove, on demand, that it protected what its clients trusted it with.

You Do Nothing

We scan your full environment — devices, domains, email, EFIN access, vendor connections. You get a risk report and a remediation blueprint.

WEEK 2 · WE DEPLOY

Staff Get Access

We configure and install everything. Your team gets one onboarding email and access to certification modules built for tax professionals.

WEEK 3 · WE TEST

You See Your Report

A full Level-1 penetration test and compliance verification. You receive a clean, audit-ready evidence file. Your dashboard goes live.

WEEK 4 · PROTECTED

We Monitor Forever

🎓

The MOSTRO Firm Security Certification

Every staff member who completes certification generates a timestamped training record. Your dashboard shows completion across your whole team — so when the IRS, your state board, or a plaintiff's attorney asks what security training your people received, you have the evidence file to prove it. That's the IRS Publication 4557 employee-training requirement, handled.

MOSTRO 1040 handles deployment, configuration, monitoring infrastructure, and compliance documentation support. FTC Safeguards, IRS Pub 4557, and IRC §7216 compliance remain the responsibility of the firm. Consult qualified legal counsel for your specific obligations.

Common Questions

FREQUENTLY ASKED QUESTIONS

Do I really need a WISP — or is that just for big firms? +
Yes, you need one. Since 2024, IRS Form W-12 (Line 11) requires every PTIN holder to certify — under penalty of perjury — that they maintain a Written Information Security Plan. There is no minimum-client threshold: a preparer filing 11 returns has the same obligation as a firm filing 10,000. IRS Publication 4557 defines the requirement; Publication 5708 provides the template. A downloaded PDF you never implemented is not a WISP — and that's exactly the gap we close.
Does the FTC Safeguards Rule apply to accountants and EAs? +
Yes. Under the Gramm-Leach-Bliley Act, tax preparers and accounting firms are classified as "financial institutions" — the same category as banks and investment firms. That means you're subject to the FTC Safeguards Rule, which requires a written security program, vendor oversight, employee training, and incident-response planning. Penalties under the amended rule can reach tens of thousands of dollars per violation, per day. (Figures are based on publicly available FTC guidance and are subject to change.)
What is IRC §7216 and why should I care? +
Section 7216 of the Internal Revenue Code makes the knowing or reckless unauthorized disclosure or use of taxpayer information a federal crime, with potential fines and imprisonment. Every time a staffer pastes a client's return into a personal, unmonitored AI tool, you're risking exactly that kind of disclosure — under your firm's PTIN. Our Protected AI platform gives staff powerful AI inside a logged, governed environment so the productivity stays and the exposure goes.
What happens to taxpayer data when a seasonal preparer leaves? +
Without a system, usually nothing documented — which is the problem. The Offboarding Shield handles every departure cleanly: access is revoked, data custody is documented, and you keep a timestamped record of what each person could access and what was returned. So if a question ever comes up months later, you have an answer instead of a guess.
What about my EFIN and PTIN if I get breached? +
Your EFIN is the master key to everything you e-file, and a compromise can lead the IRS to suspend it — mid-season, when it hurts most. We put MFA and active monitoring around your EFIN, PTIN, and IRS accounts, and maintain the documentation you'd need to respond fast if something looks wrong.
Will my cyber insurance even pay out without this? +
Read your policy. Most carriers now require a documented WISP and specific controls as a condition of coverage — and after a breach, they audit your security program before paying. If you can't produce evidence the controls were actually in place, claims can be reduced or denied even though you paid every premium. MOSTRO 1040 builds the evidence file before the breach, not after.
What does MOSTRO 1040 cost, and how fast can it deploy? +
Pricing is per firm with unlimited users, and it scales down per-person as your team grows — far below the cost of hiring the same capability in-house. Deployment runs on a four-week timeline, and your staff are onboarded with their own secured infrastructure quickly after signing. Book a discovery call for your firm's specific number.
