October is Cybersecurity Awareness Month. For accounting firms, CPA practices, tax professionals, bookkeepers, payroll providers, and financial service organizations, it is a good time to take a closer look at what you know, what you assume, and what is actually protecting your firm.
Not all cybersecurity advice is accurate. Some advice has been repeated for so long that it sounds like fact, even when it is outdated, incomplete, or not strong enough for the kind of client financial data your team handles every day.
That creates blind spots. Cybercriminals look for those blind spots, especially in firms where one exposed Microsoft 365 account, one missed update, one compromised payroll login, or one bad click during tax season can create a serious problem.
The stakes are high for accounting and financial service organizations in Columbia, Boone County, and across Mid-Missouri. Your systems may contain tax returns, financial statements, payroll records, bookkeeping files, bank information, W-2s, 1099s, nonprofit reports, local government records, construction job costing, agricultural financials, and sensitive small business data.
The good news is that these gaps are usually simple to address once you know where to look. Here are six cybersecurity myths we hear from local businesses and professional firms, along with the facts behind them.
Myth 1: We are too small for cybercriminals to care about
There is no accounting firm too small for an opportunistic cybercriminal. It does not matter if you are a solo tax preparer, a bookkeeping practice with a few employees, a payroll provider, or a larger CPA firm serving clients across Columbia, Ashland, Hallsville, Centralia, Fulton, Boonville, Mexico, Moberly, Jefferson City, or California.
If you have exposed accounts, valuable information, access to money, or vulnerable systems, you may be a target. Your firm could also provide an entry point into a client, vendor, bank, software provider, or payroll platform.
That matters in our region because accounting firms often sit in the middle of a busy local economy. You may be serving healthcare organizations, professional services firms, nonprofits, local governments, construction companies, manufacturers, agricultural businesses, startups, small businesses, and family-owned companies. Columbia’s economy, influenced by healthcare, research, students, startups, and a highly educated workforce around Mizzou, also creates a wide variety of financial workflows and compliance needs.
Fact: Hackers choose targets based on opportunity, not firm size.
Myth 2: Employees will recognize a phishing email
The obvious phishing emails filled with typos and suspicious senders are not the only threat anymore. Many scams are polished, personalized, and designed to look like they came from someone you trust.
For accounting teams, this can show up as a fake client sending a tax document, a vendor changing ACH instructions, an employee requesting payroll changes, a partner asking for a financial statement, or a software notice that looks like it came from Microsoft 365, QuickBooks, a tax platform, or a bank.
Artificial intelligence has made it harder to spot a scam by reading the message alone. Your team also needs to look at the behavior behind the request.
Ask whether the supposed sender would:
- Make an unusual request during a busy deadline
- Change payment, payroll, or direct deposit instructions
- Request tax records, W-2s, financial statements, or client financial data
- Send a new or unusual login link
- Pressure your team to bypass normal review
If something feels unusual, slow down and verify it through a separate channel. Call the person using a known phone number. Do not reply to the message or use the contact information it provides.
This is especially important during tax season, when volume is high, employees are moving fast, and clients may already be sending documents from many different sources.
Fact: A convincing email can still be a scam.
Myth 3: MFA fully protects our accounts
Multi factor authentication is an important layer of protection, but it is not invulnerable. Criminals use MFA fatigue attacks to take advantage of employees who receive repeated approval requests.
For example, prompt bombing can flood a phone with login requests. The attacker hopes the employee eventually approves one just to make the notifications stop. If that account has access to Microsoft 365 email, bookkeeping systems, tax software, client portals, payroll records, or shared files, the damage can move quickly.
MFA should be supported by strong passwords, managed devices, access controls, security awareness training, and monitoring. Where possible, use phishing resistant authentication methods instead of relying only on approval notifications or text messages.
Accounting firms should also review who has access to what. Seasonal staff, remote bookkeepers, interns, former employees, and outside contractors should not keep access longer than necessary. Employee efficiency matters, but convenience should not quietly become unnecessary risk.
Fact: MFA should be part of a broader security strategy.
Myth 4: Our backups have us covered
Ask yourself a practical question. If ransomware locked up your files tomorrow, could your firm restore its data? How long would that take?
A backup only helps when it is available, protected, and tested. Many businesses discover during an incident that backups were incomplete, connected to the network, too old, or impossible to restore quickly.
For accounting and financial service organizations, backup and disaster recovery is not just an IT topic. It is a business continuity topic. If your team cannot access client financial data, payroll records, tax files, bookkeeping systems, or scanned source documents, your clients may miss payroll, filing deadlines, reporting deadlines, loan requirements, board meetings, or grant reporting obligations.
Review your backup schedule, retention periods, access controls, and recovery process. Make sure Microsoft 365 data is included in the conversation, because email, OneDrive, SharePoint, and Teams are often where critical client communication and documents live.
Test the process regularly so you know what will happen before there is a crisis. A backup that has never been tested is more of a hope than a plan.
Fact: Having backups is not the same as being able to recover.
Myth 5: Cybersecurity is only IT responsibility
Your IT team or technology provider does a lot to protect your systems. They cannot control every click, password, file transfer, portal upload, payment request, or payroll change made by employees.
Cybersecurity decisions happen throughout your firm. A single bad click can open the door to malware, stolen credentials, fraudulent payments, data theft, or unauthorized access to client records.
Security awareness training helps employees recognize unusual requests and know when to ask for help. The goal is not to make everyone a technical expert. The goal is to help people make safer decisions during a busy workday.
That is especially important for accounting firms because your busiest seasons are also when criminals know your team is under pressure. Tax deadlines, month-end close, payroll processing, financial statement preparation, nonprofit reporting, and audit requests all create urgency. Urgency is exactly what phishing emails try to exploit.
Good cybersecurity should also support employee efficiency. Clear processes, secure document sharing, reliable Microsoft 365 configuration, good password management, and well-defined access controls can reduce confusion and help your team work faster without cutting corners.
Fact: Training employees to make good decisions strengthens your cybersecurity.
Myth 6: We know what to do if something happens
Imagine it is Tuesday morning in the middle of tax season and several employees suddenly cannot access client files. Or payroll records are unavailable the day before a client payroll run. Or email is acting strange and clients are receiving suspicious messages from a staff account.
That is when many firms discover they have not answered a few basic questions.
- Should employees shut down their computers?
- Who contacts IT or your technology provider?
- What happens if email and phone systems are unavailable?
- When should your insurance company be involved?
- Who communicates with clients, banks, software vendors, and payroll partners?
- How will employees receive updates?
- Which client services must be restored first?
- How will you document what happened?
Do not rely on memory during an incident. Create a written incident response plan, assign responsibilities, and test the plan with your team. Your response process should include backup communication methods, a clear escalation path, and practical decisions about business continuity.
For firms serving clients across Columbia, Boone County, Rocheport, Harrisburg, Fulton, Boonville, Jefferson City, and the surrounding region, continuity matters. Your clients depend on you for deadlines, payroll, financial reporting, and guidance when their own businesses are under pressure.
Fact: Your recovery plan should not debut during an incident.
Cybersecurity awareness starts with the facts
Cybersecurity Awareness Month is a good reminder to check the assumptions guiding your decisions.
Myths are comfortable. They can make you feel protected without requiring you to look closely at the details. But many cybersecurity gaps come from believing everything is handled when it is not.
At Tigerhawk Technologies, we help local businesses and professional firms separate real protection from false confidence. That starts with understanding your accounts, devices, Microsoft 365 environment, backups, policies, employee workflows, and response plans.
If any of these myths sound familiar, take a closer look at where your firm stands. Schedule a discovery call and let us help you identify the practical steps that can reduce your risk.
Practical questions from Mid-Missouri accounting teams
What cybersecurity steps should a Columbia CPA firm prioritize before tax season?
For most firms, start with Microsoft 365 security, multi factor authentication, password management, endpoint protection, secure client document exchange, and tested backups. Then train employees on phishing, payroll change scams, and unusual client requests. The goal is to reduce risk before volume spikes and your team is working under tax season pressure.
Do accounting firms in Boone County need separate backups for Microsoft 365 and bookkeeping systems?
Usually, yes. Many firms assume Microsoft 365, tax software, or bookkeeping platforms automatically provide the recovery they need. That is not always true. Your firm should know what data is backed up, how long it is retained, who can restore it, and how quickly email, client files, payroll records, and financial documents can be recovered.
How can a bookkeeping or payroll provider improve cybersecurity without slowing employees down?
Good security should make work clearer, not harder. Standardized access controls, secure file sharing, password managers, managed devices, and well-configured Microsoft 365 tools can reduce confusion and rework. For bookkeeping and payroll teams in Columbia and Mid-Missouri, the key is building repeatable processes that protect client financial data while supporting daily productivity.
