Top 10 Cybersecurity Tips for Small Businesses

Cybercriminals don’t only target large companies. Small businesses can be just as appealing because they often manage sensitive data with fewer security resources.

Many attacks are opportunistic, with criminals looking for easy entry points such as weak passwords, outdated software, or unsecured email accounts. Verizon’s 2025 small- and medium-sized business report examined 3,049 security incidents involving organizations with fewer than 1,000 employees, and 2,842 involved confirmed data disclosure, reinforcing the reality that cybersecurity incidents remain a business risk for smaller organizations.

Small businesses may have limited budgets or no dedicated security team, but improving cybersecurity does not always require expensive tools. These practical tips can help reduce common risks and strengthen everyday protections.

Why cybersecurity matters for small businesses

A cyberattack can disrupt day-to-day operations and create problems for small businesses that take a lot of time, effort, and money to resolve.

• Lost revenue and downtime: Employees may be unable to access files, process payments, communicate with customers or complete orders.
• Stolen customer or employee information: Exposed personal data can create identity theft and privacy risks.
• Fraudulent payments or transfers: Criminals may use compromised email or financial accounts to redirect invoices, payroll or vendor payments.
• Recovery and legal expenses: A business may need technical support, legal guidance, customer notifications, credit monitoring or new equipment.
• Damage to customer trust: Customers may reconsider sharing information with a business after a breach.
• Regulatory or contractual responsibilities: Data-protection laws, vendor agreements or insurance policies may require specific security and reporting practices.

It’s important to remember that cybersecurity isn’t a one-and-done issue. As your company grows, adds new technology and works with more employees or vendors, its risks can change too.

The Federal Trade Commission (FTC) recommends using the NIST Cybersecurity Framework, which groups cybersecurity into six areas: govern, identify, protect, detect, respond and recover. These areas can help businesses understand their risks, strengthen protections, spot suspicious activity and prepare for a faster recovery.

10 cybersecurity tips for small businesses

No single security tool can prevent every attack. A layered approach makes it harder for criminals to gain access and helps limit the damage when something goes wrong. Follow these ten tips to protect your business.

1. Identify your most important data and systems

Start by creating an inventory of the information, technology and services your business relies on.

This may include:

• Customer and employee records
• Payment and banking information
• Email accounts
• Laptops and mobile devices
• Websites and online stores
• Point-of-sale systems
• Cloud storage
• Payroll and accounting software
• Vendor platforms

Identify where sensitive information is stored, who can access it and how long it needs to be kept. Delete data the business no longer needs using a secure disposal process.

Next, consider what would happen if each system became unavailable. This can help you prioritize protections for the accounts, devices and information that are most important to daily operations.

2. Keep software and devices updated

Cybercriminals often take advantage of known software vulnerabilities. Security updates help close these gaps.

Turn on automatic updates when possible for:

• Operating systems
• Web browsers
• Business applications
• Mobile devices
• Routers
• Website software and plug-ins
• Antivirus and other security tools

Replace software and devices that no longer receive security support. The FTC recommends setting a regular update schedule and installing available security patches promptly.

Pro tip: Keep a basic inventory showing which employee or vendor is responsible for updating each system.

3. Use strong, unique passwords

Require a different password for every important business account. Reusing passwords allows one compromised account to put several others at risk.

Strong passwords should be long and difficult to guess. A password manager can help employees create and store unique credentials without needing to remember each one.

Businesses should also:

• Change default passwords on routers, devices and software
• Avoid sharing passwords by email or text
• Remove shared accounts when individual logins are available
• Disable accounts promptly when an employee or contractor leaves
• Limit repeated login attempts to reduce password-guessing attacks

4. Turn on multifactor authentication

Multifactor authentication, or MFA, requires an additional form of verification beyond a password. This may include an authenticator app, security key, biometric scan or temporary code.

Require MFA for important systems, including:

• Business email
• Banking and payment accounts
• Cloud storage
• Payroll and accounting platforms
• Administrative accounts
• Remote network access
• Social media accounts

MFA can help block someone who has obtained an employee’s password. However, employees should never approve an unexpected login request or share a verification code with someone who contacts them.

5. Train employees to recognize cyber threats

Employees may be the first to notice a suspicious email, unusual login, fraudulent payment request, or infected device.

Provide cybersecurity training when employees join the company and refresh it regularly. Cover topics such as:

• Phishing emails and text messages
• Suspicious links and attachments
• Payment and invoice scams
• Safe password practices
• Remote work security
• Lost or stolen devices
• Reporting unusual activity

Training should make it easy to report a mistake without fear of blame. Fast reporting can help the business contain an incident before it spreads.

6. Protect business email accounts

Business email is often connected to financial accounts, customer communications, password resets and sensitive files. A compromised inbox can give an attacker access to much more than email.

Protect accounts with unique passwords and MFA. Employees should independently verify unusual requests to:

• Send money
• Purchase gift cards
• Change payment instructions
• Share tax or payroll information
• Provide passwords or verification codes

Businesses that use their own domain should also enable Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC). These email-authentication tools help receiving systems determine whether a message was authorized by the business’s domain and can make impersonation more difficult.

7. Limit access to sensitive information

Employees and vendors should only have access to the systems and information they need for their work.

Use individual accounts rather than shared credentials and assign different permission levels based on job responsibilities. Administrative access should be limited to as few people as possible.

Review permissions regularly and remove access when:

• An employee changes roles
• A project ends
• A contractor completes their work
• A vendor relationship ends
• An employee leaves the company

The same principle applies to vendors. Evaluate how they protect data before sharing information or allowing them to connect to business systems. Put security expectations, access limits and breach-notification requirements in the contract.

8. Secure networks, devices, and remote access

Change the default administrator name and password on business routers. Use WPA2 or WPA3 encryption, update router software and turn off remote management when it is not needed.

Keep guest Wi-Fi separate from the network used for business systems. This can prevent customer or personal devices from connecting directly to sensitive company resources.

Protect laptops, phones, and tablets with:

• Screen locks
• Device encryption
• Security software
• Automatic updates
• Remote location and erasure tools

9. Back up important business data

Regular backups can help a business recover after ransomware, equipment failure, accidental deletion or another disruptive event.

Back up important files and the systems needed to use them. Keep at least one copy separated from the main network so an attacker cannot easily encrypt or delete it along with the original data.

• Backups may be stored:
• In secure cloud storage
• On an external drive kept offline
• Through a managed backup provider
• In more than one geographic location

Test backups regularly to confirm that files can actually be restored. A backup that is outdated, incomplete or inaccessible may not help during an emergency.

The FTC recommends making backups part of regular business operations and keeping important recovery copies off the network.

10. Prepare an incident response plan

A written incident response plan gives employees clear instructions when a cyberattack or data breach occurs.

The plan should explain:

• Who employees should contact
• How to disconnect affected devices
• Who will investigate the incident
• How the business will continue operating
• When to contact banks, vendors, insurers, legal counsel or law enforcement
• How customers and employees will be notified when required
• How data and systems will be restored
• How the incident will be documented

Include contact information for internal decision-makers and outside partners. Keep a copy of the plan somewhere accessible even if company systems are unavailable.

Review and test the plan through a simple tabletop exercise. Walking through a possible phishing attack, ransomware incident, or vendor breach can reveal missing information before a real emergency occurs.

 

How often should a small business review its cybersecurity?

Complete a broader cybersecurity review at least once a year. Businesses should also reassess their protections:

• After adding new software, vendors or payment systems
• When employees begin working remotely
• After staffing or leadership changes
• Following a cyberattack or suspicious event
• When legal, contractual or insurance requirements change

Some tasks need more frequent attention. Install software updates as they become available, monitor alerts regularly, review access permissions throughout the year and test backups on a consistent schedule.

Employee training and the incident response plan should also be updated whenever new scams, technologies or business processes create different risks.

 

Build a stronger cybersecurity foundation

Small businesses do not have to fix every cybersecurity risk at once. Start by protecting the systems and information your business depends on most, then strengthen those defenses over time.

Keep software updated, use strong passwords and multifactor authentication, train employees, limit access and maintain reliable backups. It is also important to have a clear plan for responding when something goes wrong.

Make cybersecurity part of your everyday business operations.
