Cybersecurity Spring Cleaning: 10 Quick Fixes to Protect Your Small Business

Spring is a great time to tidy up — not just your office, but your digital defenses too. A quick cybersecurity checkup can go a long way in protecting your small business from today’s cyber threats.

Here are 10 simple steps you can take this week to strengthen your security.

1. Review Who Has Access to What

Employees come and go. Vendors change. Now’s a great time to:

• Remove unused accounts — especially those with access to customer data or the ability to move money

• Limit access to only what's necessary to get the job done

• Review shared logins and update passwords if access has changed

Old accounts are one of the most common ways attackers gain access.

2. Reset Old Passwords

If you’re using the same passwords for more than 6 months, consider updating them. Passwords that haven’t been changed in over a year are especially worth changing.

For example, a password that hasn’t been changed in a long time may already be known to others through past sharing, reuse across multiple websites, or exposure in a data breach. Updating the password reduces the chance that someone can continue accessing your systems without authorization.

Bonus tip: Most smartphones and web browsers include built-in password managers that can generate and store strong passwords securely. Using these tools is much safer than reusing passwords or writing them down. As your business grows, you may also want to consider a centralized password manager to simplify access and improve security.

3. Turn On Multi-Factor Authentication (MFA)

MFA adds an extra layer of protection by requiring a second verification step using a mobile app or text code. Passwords can sometimes become exposed through phishing or data breaches. MFA helps prevent unauthorized access even if that happens.

For example, even if someone obtains your email password, they would still need access to your phone or authentication app to complete the login.

This simple setting can stop the majority of unauthorized login attempts and account takeovers.

4. Update Your Software

Outdated apps and operating systems are a common entry point for attackers because they may contain known security vulnerabilities.

For example, when a software company releases an update, it often includes fixes for security weaknesses that have already been identified. Delaying updates can leave those weaknesses exposed.

Make sure computers, phones, business apps, and routers are running the latest updates. Enable automatic update features whenever possible.

5. Back Up Your Data

If ransomware, hardware failure, or even accidental deletion wipes your files, backups can keep your business running.

For example, if an employee accidentally deletes an important folder or a computer fails unexpectedly, a recent backup can allow you to quickly restore critical information such as accounting records, client files, or project documents and keep operations moving.

Check that:

• Backups run automatically

• Important files are included

• Backups are tested periodically to confirm data can be restored

A backup is only useful if it actually works when you need it.

6. Check for Suspicious Email Rules

Some email attacks secretly create inbox rules that forward messages externally or hide important emails.

For example, an attacker might create a rule that automatically forwards copies of invoices or payment requests to an outside address without the employee realizing it.

Take a moment to review your email settings and confirm there are no unfamiliar forwarding rules or filters in place.

7. Remove Old Apps, Integrations, and Browser Extensions

Over time, many tools connect to your email, file storage, CRM, or accounting system.

For example, an employee may have connected a scheduling tool, file-sharing app, or browser extension to their work email months ago and forgotten about it. If that tool is later compromised, it could still have access to company information.

Remove anything you no longer use, including:

• Old software trials

• Third-party integrations

• Unnecessary browser extensions

Unused connections can create hidden risk.

8. Review Administrator Privileges

Not everyone needs full control over systems.

For example, if an employee with administrator access clicks a malicious link, an attacker could gain the ability to create new accounts, change security settings, or access sensitive company data.

Check who has administrator access to:

• Microsoft 365 / Google Workspace

• Accounting systems

• Website platforms

• Security tools

Reducing admin privileges limits the damage a compromised account can cause.

9. Confirm Devices Are Protected

Make sure company devices have basic protections in place, such as:

• Screen lock enabled

• Antivirus or endpoint protection installed

• Lost or stolen devices can be locked or wiped

For example, if a laptop or phone is lost or stolen, protections such as screen locks and remote wipe capabilities can help prevent unauthorized access to company emails, files, or saved passwords.

Laptops and phones often contain more sensitive information than we realize.

10. Refresh Your Cybersecurity Guidelines with Your Team

Even a quick 10-minute reminder can make a big difference.

Consider reminding employees how to:

• Spot suspicious emails

• Avoid clicking unknown links

• Report anything unusual quickly

• Protect company information when working remotely

Cybersecurity works best when everyone understands their role in protecting the business.

Final Thought

Cybersecurity doesn’t have to be complicated — it just needs to be consistent.

These ten steps take less time than spring cleaning your garage, and they can significantly reduce your risk associated with common cyber threats. Small improvements, done regularly, make a meaningful difference.
