The email looks real. The voice sounds familiar. The request makes sense.
That's the problem.
Double Rule is the security team for accounting firms that don't have one. We protect your people, accounts, devices, and client data against threats that are getting harder to recognize.
Free Security Snapshot. No credentials. Nothing installed.
AI didn't invent phishing, fraud, or impersonation.
It made them a lot more convincing.
An attacker can use information about your clients and firm to create messages that look like they belong in your inbox.
A familiar voice on the phone isn't the proof it used to be.
Stolen credentials can make an attacker look just like someone who belongs there.
Attackers use context, timing, and trust to get people to move money, share files, or hand over access.
Would your team know the difference?
Most small accounting firms weren't built with a security department.
That's where we come in.
Double Rule works alongside your existing IT provider to run the security program behind your firm.
We help prevent attacks, prepare your firm to recover when something goes wrong, test your defenses, and keep the evidence that your security program is actually working.
PROTECT
Protect the places attackers are most likely to target, including your email, employee accounts, computers, client data, and people.
RECOVER
We help make sure critical data is backed up, recovery plans exist, responsibilities are clear, and your firm knows what to do when something goes wrong.
TEST
We continuously look for weaknesses, exposed systems, configuration problems, and other gaps that could give an attacker a way in.
PROVE
Double Rule helps keep your security program documented and the proof behind it ready when someone asks.
Your IT provider is important.
They manage Microsoft 365. Fix laptops. Set up employees. Keep software and networks working.
But keeping technology running and owning cybersecurity are different jobs.
Your clients trust you with some of the most valuable information they have.
And something attackers may value even more:
Your clients trust you.
That trust makes a compromised accounting firm incredibly useful to an attacker.
They don't just gain access to information.
They gain a trusted path to your clients.
That's why we built Double Rule specifically for accounting firms.
You may have 8 employees instead of 800.
Attackers don't care.
They care about what you have access to.
Double Rule brings the structure of a real security program to accounting firms without requiring you to hire an internal security team or assemble a pile of security products yourself.
Practical enough for a small firm.
Serious enough for the information you protect.
A CLIENT ASKS
"How do you protect our information?"
You should have a better answer than "our IT company handles it."
YOUR CYBER INSURER ASKS
"Do you use MFA, endpoint protection, backups, and security training?"
You should know the answer.
A SECURITY QUESTIONNAIRE ARRIVES
"Describe your security controls."
You shouldn't have to figure it out from scratch.
SOMEONE ASKS FOR YOUR SECURITY PROGRAM
"Show us what you're doing to protect sensitive information."
You should have something real to show them.
Double Rule helps operate the controls and keeps the evidence behind them organized.
Protect it. Recover it. Test it. Prove it.
We handle the security program.
You get one team responsible for helping protect your firm year-round.
A team led by a founder who works in AI security every day. Avery runs every Free Security Snapshot personally and is your named security contact during business hours.
