31 Cybersecurity Tips to Make You a Human Firewall

Every employee who uses email, accesses company systems, works with sensitive information, or connects a device to the internet plays a vital role in protecting their organization. Engaging in strong employee cybersecurity habits helps prevent phishing, account breaches, data exposure, and other common threats.

October is a natural time to refresh those habits. In recognition of Cybersecurity Awareness Month, we’ve compiled 31 cybersecurity tips for employees, one for each day of the month.

From strengthening passwords and enabling multi-factor authentication (MFA) to recognizing phishing attempts and reporting suspicious activity, these simple steps can help employees build stronger security habits at work and at home.

You don’t need to be a cybersecurity expert to make a difference. Small, consistent actions can help protect accounts, devices, company data, and the people who rely on them.

What are the most important cybersecurity tips for employees?

The most important cybersecurity tips for employees include using strong, unique passwords, enabling multi-factor authentication (MFA), recognizing phishing attempts, protecting sensitive information, keeping devices and software updated, securing remote connections, and reporting suspicious activity promptly.

Here is our list of 31 vital tips for employees to build strong cybersecurity habits and transform you into a human firewall.

Protect Your Accounts and Access

1. Use Strong, Unique Passwords

Use a long, unique password or passphrase for each account. Avoid reusing passwords across accounts, both work and personal, especially for accounts that provide access to sensitive or organizational information.

2. Enable Multi-factor Authentication

Multi-factor authentication (MFA) adds another layer of protection beyond your password. Whenever an application offers MFA, enable it and use the authentication method approved by your employer.

3. Use a Password Manager

A password manager can generate and securely store unique passwords, so you don’t have to remember them all. Use an organization-approved password manager for work credentials.

4. Don’t Share Your Passwords

Your password belongs to you. Never share it through email, text, chat, or over the phone, even if someone claims to be from IT.

5. Protect Privileged Accounts

Administrative accounts have additional access and therefore require additional protection. Don’t use privileged accounts for routine activities when a standard account is available.

6. Lock Your Screen

Get into the habit of locking your computer whenever you step away, even if you’re only leaving for a few minutes. A locked screen is a simple way to prevent unauthorized access.

Recognize and Avoid Phishing

7. Think Before You Click

Don’t click links simply because a message looks familiar or urgent. Hover over links when possible, and consider whether you were expecting the message before opening it.

8. Check the Sender

Look closely at the sender’s address, not just the display name. Attackers often impersonate coworkers, executives, vendors, or familiar companies using slightly altered email addresses.

9. Be Suspicious of Urgent Requests

Requests involving urgency, money, passwords, gift cards, or sensitive information deserve extra attention. Social engineering attacks often create pressure, so recipients act before thinking.

10. Don’t Open Unexpected Attachments

An unexpected attachment could contain malware or lead to a phishing site. If you’re unsure about an attachment, verify it with the sender through a trusted communication method before opening it.

11. Verify Unusual Requests

If someone asks you to transfer money, change payment information, provide sensitive data, or make an unusual account change, verify the request independently.

Don’t rely solely on the contact information included in the suspicious message.

12. Report Suspicious Messages

Don’t simply delete a suspicious email and move on. Follow your organization’s reporting process so the security team can investigate the message and warn others if necessary.

Protect Company Data

13. Know What Information You’re Handling

Before sharing or storing information, understand whether it is public, internal, confidential, or otherwise sensitive. Treat sensitive information according to your organization’s policies.

14. Opt Out of AI Training Where You Can

Review privacy settings in your apps and turn off options that use your data to train AI. At work, never enter confidential information into public AI tools.

15. Share Information Only with People Who Need It

Use access control and the principle of least privilege when sharing information. Just because someone works at the same organization doesn’t mean they need access to every file or system.

16. Check File-Sharing Permissions

Cloud platforms make collaboration easy, but improperly configured permissions can expose sensitive information.

Before sharing a file, check who can access it and whether they can view, edit, download, or reshare it.

17. Don’t Use Unapproved Channels for Sensitive Information

Avoid using personal email, personal cloud storage, consumer messaging apps, or other unapproved services to store or transmit company information.

Use the tools provided and approved by your organization.

18. Back Up Important Information

Follow your organization’s backup procedures for important work files. Don’t assume that a file is backed up simply because it exists on your computer.

19. Dispose of Sensitive Information Securely

Don’t throw sensitive documents, storage devices, or other information in the regular trash without following your organization’s disposal procedures.

If you are uncertain about proper disposal procedures, consult your IT, security, or records management team for guidance.

Secure Your Devices and Connections

20. Install Software and Security Updates

Software updates often include fixes for security vulnerabilities. Install updates promptly according to your organization’s procedures, and don’t repeatedly postpone required updates.

21. Use Company-Approved Security Software

Don’t disable security tools or install unauthorized software on work devices. Security software such as endpoint protection can help detect and prevent threats.

If a security tool interferes with your work, contact IT rather than disabling it yourself.

22. Secure Your Mobile Devices

Your phone may provide access to email, cloud applications, company systems, and sensitive information.

Use a strong device passcode, enable biometric authentication when appropriate, keep the operating system updated, and report a lost or stolen device promptly.

23. Be Careful with USB Drives

Unknown USB drives can introduce malware or expose sensitive information. Only use removable media that is approved by your organization and follow your organization’s USB security procedures.

24. Secure Your Home Wi-Fi

If you work remotely, secure your home network with a strong Wi-Fi password and up-to-date router software. Change default administrator credentials and use modern wireless security settings when available.

25. Be Careful on Public Wi-Fi

Public Wi-Fi can create additional security risks. When working away from the office, follow your organization’s policies for VPNs, secure connections, and access sensitive systems.

When possible, use a trusted network or approved mobile hotspot for sensitive work.

26. Keep Work and Personal Devices Separate

Using personal devices for work can create additional security and privacy risks. Whenever possible, use organization-provided devices, and follow your company’s policies for remote work and personal-device access.

Build Better Everyday Security Habits

27. Don’t Leave Devices Unattended

Don’t leave a laptop, phone, tablet, or other work device unattended in public places or unsecured areas.

If you must step away, lock the device and keep it somewhere secure.

28. Protect Your Workspace

Security applies to physical information, too. Don’t leave sensitive documents, passwords, access badges, or unlocked devices where unauthorized people can see or access them.

29. Know How to Report a Security Incident

Learn who to contact if something goes wrong. That could include accidentally clicking a phishing link, losing a device, sending information to the wrong person, or noticing suspicious activity. Prompt cybersecurity incident reporting can give your organization’s security team more time to respond.

30. Stay Sharp with Security Awareness Training

Complete your assigned training on time and treat it as an ongoing practice rather than a yearly checkbox. Threats change quickly, so pay attention to phishing simulations, newsletters, and reminders from your security team.

Apply what you learn in practice daily, at work, and at home.

31. Make Cybersecurity an Everyday Habit

Cybersecurity shouldn’t end when October does. Build small security practices into your normal routine: pause before clicking, protect your accounts, secure your devices, and speak up when something doesn’t look right.

The goal isn’t perfection. It’s about creating consistent habits that make your organization more difficult to compromise.

Why Employee Cybersecurity Matters

Security tools and technology are important, but they aren’t the only part of an organization’s cybersecurity program.

Employees interact with email, applications, files, devices, customers, vendors, and other people every day. That means they may encounter phishing attempts, suspicious requests, malware, accidental data exposure, or other security issues before anyone on the IT or security team knows about them.

Strong security awareness training helps employees recognize these situations and understand what to do next.

Most importantly, employees should feel comfortable reporting mistakes and suspicious activity. An employee who accidentally clicks on a phishing link should know that reporting it quickly is more important than being embarrassed about the mistake.

A strong security culture encourages people to speak up early.

Turn These Tips into Everyday Security Habits

The best cybersecurity practices are the ones employees can actually maintain.

Start with the basics:

• Use strong, unique passwords.
• Enable MFA.
• Think before clicking.
• Verify unusual requests.
• Protect sensitive information.
• Keep devices updated.
• Secure your Wi-Fi connections.
• Report suspicious activity quickly.

These actions may seem small, but together they can strengthen an organization’s overall security posture.

Cybersecurity is a shared responsibility. IT and security teams provide the technology, policies, and support, but employees play a critical role in putting those protections into practice.

Make Cybersecurity a Daily Habit

Cybersecurity Awareness Month is a good reminder to review your security habits, but these practices matter throughout the entire year.

Employees don’t need to become cybersecurity experts to contribute to a safer organization. Taking a few seconds to verify a request, lock a computer, enable MFA, or report a suspicious email can make a meaningful difference.
