Small business owners often think cybercriminals are not interested in them. “We’re too small to be a target,” they say. “We don’t have anything worth stealing.”

The reality is the opposite. According to industry research, small businesses are targeted in the majority of all cyberattacks. The reason is simple: attackers know small businesses typically have weaker defenses than large enterprises, while still holding valuable customer data, banking credentials, and healthcare or financial information.

After years of working with small and mid-sized businesses, I see the same five mistakes made over and over again. The good news? All of them are fixable, often with modest investment and a little discipline. Here they are, in order of how often they show up.

Mistake #1: No Multi-Factor Authentication (MFA)

This is the single most common and most dangerous security gap in small business environments. Staff log into Microsoft 365, QuickBooks Online, banking websites, and other critical services with just a username and password. When (not if) one of those passwords gets compromised, the attacker has full access.

Passwords get compromised all the time. Someone reuses the same password across multiple sites. A breach at a random service leaks their credentials. A phishing email tricks them into entering their password on a fake login page. These things happen constantly.

The fix: Turn on Multi-Factor Authentication (MFA, sometimes called 2FA) for every business account that supports it. This means even if a password is stolen, the attacker still needs a second factor (usually a code from your phone) to log in. Microsoft reports that MFA blocks over 99% of account compromise attempts.

Priority accounts to enable MFA on first:

  • Microsoft 365 / Google Workspace (email)
  • Banking and financial accounts
  • QuickBooks or other accounting software
  • Any system with customer data (CRM, EHR, etc.)
  • Cloud storage (Dropbox, OneDrive, Google Drive)

Use an authenticator app (Microsoft Authenticator or Google Authenticator) rather than SMS codes when possible. SMS can be intercepted through SIM-swapping attacks.

Mistake #2: Untested Backups (Or No Backups At All)

Almost every small business has something they call a backup. The problem is that very few have tested their backups in the last twelve months. When ransomware hits, or when a server fails, they discover the hard way that their backup either was not running, was not capturing what they thought it was, or cannot actually be restored.

Common backup failures I have seen in the field:

  • Backup drive sitting on top of the server that got encrypted along with everything else
  • Cloud backup that stopped syncing eight months ago because the credentials expired
  • USB drive rotated weekly, but full for the last six months so only one backup exists
  • Backups only covering some systems and not others (usually missing the most important one)

The fix: Implement proper backup following the 3-2-1 rule: three copies of your data, on two different types of media, with one copy stored offsite. Then test restoration at least quarterly. If you cannot restore, you do not have a backup.

Modern business-grade backup solutions like Datto or Veeam can automate this entire process, including verification that backups are actually recoverable. These are not expensive for small businesses and the peace of mind is worth every dollar.

Mistake #3: Out-of-Date Software and Operating Systems

Every month, Microsoft and other vendors release security patches for newly discovered vulnerabilities. Every month, small businesses fail to apply them because nobody is in charge of patching. Within weeks of a vulnerability being disclosed, attackers are actively scanning the internet looking for unpatched systems.

Even worse: many businesses are still running Windows 10 computers that have reached end of support, or Windows Server versions that stopped receiving security updates years ago. These systems are, in the most literal sense, indefensible. Every day you use them, you are running software that will never again receive a security patch.

The fix: Implement automated patch management across all computers and servers. A managed IT service will handle this for you automatically. If you are doing it yourself, at minimum:

  • Enable automatic Windows Updates on every computer
  • Keep browsers (Chrome, Edge, Firefox) set to auto-update
  • Upgrade any Windows 10 computers to Windows 11 or replace them
  • Replace any out-of-support Windows Server versions
  • Keep third-party software (Adobe, Java, etc.) updated

Consider this the digital equivalent of locking your doors at night. It is not sophisticated and it will not stop every attack, but failing to do it invites disaster.

Mistake #4: No Email Security Beyond the Default

The overwhelming majority of cyberattacks against small businesses start with email. Phishing emails trick employees into clicking malicious links or entering credentials on fake websites. Business email compromise (BEC) attacks trick finance staff into wiring money to criminals. Ransomware arrives as an innocent-looking attachment.

The default email security in Microsoft 365 or Google Workspace is pretty good, but it is not enough. Attackers specifically design their campaigns to bypass the default filters. Business email needs additional protection layers.

The fix: Deploy advanced email security beyond the default. Solutions like Avanan, Proofpoint Essentials, or Microsoft Defender for Office 365 add layers that specifically catch:

  • Advanced phishing that mimics trusted senders
  • Business email compromise and impersonation
  • Malicious attachments and URLs (including ones activated after delivery)
  • Domain spoofing (emails pretending to be from your CEO)

Just as important, train your staff. The best technical protections in the world cannot prevent an employee from wiring money to a criminal who has socially engineered them. Security awareness training, delivered consistently, is one of the highest-ROI investments a small business can make.

A good rule: if an email from the CEO urgently requests a wire transfer, gift cards, or sensitive information, verify it by phone using a known number before acting. This single habit has saved countless businesses from six-figure losses.

Mistake #5: No Incident Response Plan

Here is a question I ask every small business during an IT Health Check: “If you got ransomware right now, what would you do first?”

Almost nobody has a real answer. They freeze. They might mention “call IT” or “call the insurance company.” But they do not have a written plan, phone numbers are not accessible, and they do not know what legal obligations they may have under Florida data breach notification laws.

This is a serious problem. During a cybersecurity incident, minutes matter. The difference between isolating an infection in the first hour versus letting it spread overnight can be the difference between a minor cleanup and a catastrophic business disruption.

The fix: Create a simple written incident response plan that answers these questions:

  • Who do you call first if something happens? (IT provider, cyber insurance, attorney)
  • Where are those phone numbers written down? (Not just on the computer that might be compromised)
  • Who on your staff has authority to make decisions during an incident?
  • What are your legal notification obligations (customers, regulators, etc.)?
  • How will you communicate with staff if email is compromised?
  • How will you operate the business if systems are offline for a day? A week?

Print this plan. Put it somewhere you can find it without a computer. Review it with your team at least annually. Consider cyber insurance to cover the financial impact of a major incident.

The Takeaway for Small Businesses in Volusia County

Cybersecurity for small businesses is not about buying the most expensive products or hiring a team of engineers. It is about doing the fundamentals consistently: enabling MFA, testing backups, keeping systems patched, securing email, and being prepared to respond to an incident.

Every week, small businesses in Ormond Beach, Daytona Beach, and across Volusia County get hit by attacks that would have been stopped by these basic controls. The businesses that take cybersecurity seriously will weather the storm. The businesses that do not will eventually pay a much higher price.

The good news is that these fundamentals are within reach for every small business, either through a capable internal resource or through a managed services provider that handles it for you. For more on how that partnership works, see our guide to managed IT services for Ormond Beach businesses in 2026.
