Cybersecurity Tips for Remote and Hybrid Work

Remote and hybrid work are now a regular part of how many businesses operate. Employees may work from home, from the office, or from different locations throughout the week while relying on laptops, smartphones, cloud applications, video conferencing platforms, and other connected devices.

This flexibility also creates additional cybersecurity challenges. A compromised home network, reused password, phishing email, outdated software, or unsecured device can potentially expose business accounts and sensitive information.

Whether you work remotely full-time or split your time between home and the office, following practical cybersecurity practices can help protect your devices, accounts, and company data.

Watch for Phishing and Social Engineering Attacks

Phishing remains a common way attackers attempt to gain access to accounts and sensitive information. Remote and hybrid workers may receive emails, text messages, or workplace chat messages that appear to come from a coworker, manager, client, cloud-storage provider, or other trusted organization.

Common examples include messages asking you to:

• Verify your Microsoft 365 or Google Workspace account
• Reset a password
• Review or download a shared document
• Approve an unexpected login
• Send sensitive business information
• Purchase gift cards or make an urgent payment
• Open an invoice or attachment
• Join an unexpected video meeting

Attackers often create a sense of urgency to encourage people to act before carefully checking the request.

Before clicking a link or providing information, check the sender and carefully inspect the destination of links. If a request seems unusual, verify it through another trusted communication method.

If something looks suspicious, don’t click first and investigate later. Report it through your company’s established security process.

Use Strong, Unique Passwords

Remote workers often access multiple business systems, including email, cloud storage, project management platforms, VPNs, customer databases, and other applications.

Using the same password across multiple accounts can increase the potential impact of a compromised credential.

Use a unique, strong password or passphrase for every important account. A reputable password manager can make it easier to create and securely store unique passwords without having to remember each one.

Avoid using easily guessed information such as:

• Names
• Birthdays
• Company names
• Addresses
• Phone numbers
• Common words
• Predictable password patterns

If a business provides password requirements or an approved password-management system, follow those policies.

Enable Multi-Factor Authentication

Whenever available, enable multi-factor authentication (MFA) on work accounts and other important services.

MFA adds another verification step beyond a password. Depending on the service, this may involve an authenticator app, security key, biometric verification, or another approved method.

If an attacker obtains your password through phishing or another method, MFA can provide an additional layer of protection.

For business accounts, follow your organization’s approved authentication and MFA policies.

Keep Work Devices Updated

Software updates frequently include security fixes for known vulnerabilities.

Keep your operating system, web browser, applications, and security software updated. If your company manages your work computer, follow the organization’s update policies rather than attempting to bypass them.

For personal devices used for work, enable automatic updates whenever practical.

Don’t ignore repeated update notifications simply because an application appears to be working normally. An outdated device may contain security vulnerabilities that attackers can attempt to exploit.

Secure Your Home WiFi Network

Your home network is part of your remote-work environment, so it should be protected appropriately.

Start by making sure your wireless router is running current firmware. Change any default administrator credentials and use a strong WiFi password.

Where supported, use modern wireless security such as WPA3 or WPA2 rather than outdated security protocols.

You should also:

• Change default router passwords
• Keep router firmware updated
• Disable unnecessary remote administration
• Review connected devices periodically
• Use a separate guest network for visitors and smart-home devices when appropriate
• Replace older routers that no longer receive security updates

If your internet provider supplied your router, contact them for assistance with firmware updates and security settings.

Keep Personal and Work Devices Separate

Whenever possible, use company-managed devices for company work.

Avoid allowing household members to use your work laptop, particularly if it provides access to sensitive business systems.

Likewise, avoid connecting unauthorized personal devices to corporate networks or VPNs unless your organization’s policies specifically allow it.

Keeping work and personal activities separated makes it easier to maintain appropriate security controls and reduces the chance of accidental exposure.

Protect Your Physical Workspace

Cybersecurity is not limited to software and networks.

Remote workers should also consider who can physically see or access their devices and documents.

When working from home or another location:

• Lock your computer when stepping away
• Keep work documents in a secure location
• Avoid leaving sensitive information visible to visitors
• Use a privacy screen when working in public spaces if appropriate
• Store company equipment securely when it is not being used
• Do not leave laptops unattended in vehicles or other unsecured locations

These simple precautions can help prevent unauthorized access to business information.

Be Careful on Public WiFi

Working from a coffee shop, hotel, airport, or other public location can introduce additional security risks.

Whenever possible, use a trusted network or your organization’s approved secure connection. If your company provides a VPN, follow its policies for connecting to business systems.

Avoid accessing highly sensitive information over unfamiliar networks unless appropriate security protections are in place.

Also be aware of your surroundings. Someone nearby may be able to see your screen, documents, or conversations even if your digital connection is secure.

Secure Smartphones and Other Mobile Devices

Remote work often extends beyond computers. Smartphones and tablets may provide access to company email, messaging platforms, cloud applications, and other business information.

Protect these devices with a strong passcode or biometric authentication and keep their operating systems and applications updated.

You should also:

• Enable automatic security updates
• Install applications only from trusted sources
• Review application permissions
• Enable device-finding and remote-wipe features when appropriate
• Avoid leaving devices unlocked and unattended
• Report lost or stolen company devices immediately

Mobile devices should be treated as an important part of your overall cybersecurity strategy rather than as separate from your work environment.

Be Careful With Cloud Storage and Shared Files

Cloud services such as Microsoft 365, Google Workspace, OneDrive, SharePoint, Dropbox, and other platforms make remote collaboration easier.

However, incorrectly shared files or compromised cloud accounts can expose sensitive information.

Before sharing a document, check who has access and whether they actually need it. Avoid creating public or unrestricted sharing links for sensitive information unless your organization’s policies specifically require it.

Be especially cautious when receiving unexpected requests to sign into a cloud-storage account or download a shared document.

If an email directs you to a familiar cloud service, don’t automatically assume the message is legitimate. Attackers can create convincing copies of login pages designed to steal credentials.

Secure Video Meetings and Collaboration Tools

Remote and hybrid teams often rely on video conferencing and workplace messaging platforms.

Use the security features provided by your organization’s approved platform. Depending on the service, this may include passwords, waiting rooms, authentication requirements, meeting locks, and restrictions on screen sharing or file transfers.

Don’t post private meeting links publicly unless the meeting is intended to be public.

If confidential information is discussed during a meeting, make sure you are in an environment where unauthorized people cannot overhear the conversation.

Also review who has access to shared workplace channels, files, and collaboration spaces. Remove unnecessary access when appropriate and follow your organization’s access-control policies.

Back Up Important Data

Backups can help organizations recover from accidental deletion, hardware failure, ransomware, and other incidents.

Follow your company’s backup procedures and avoid storing business-critical information exclusively on a single device.

For personal files, maintain reliable backups using an appropriate cloud or external storage solution.

If your organization provides a specific backup system, follow its requirements rather than creating an independent process that could conflict with company policies.

Businesses should also periodically review whether important data can actually be recovered from their backups rather than assuming that a backup exists simply because a system reports that it is running.

Know How to Report a Security Incident

Even careful users can make mistakes.

If you accidentally click a suspicious link, provide credentials to a suspicious website, lose a company device, or notice unusual account activity, report it immediately.

Don’t wait because you are embarrassed or assume that nothing happened. Early reporting can give your IT or security team more time to secure the account, isolate a device, reset credentials, or investigate potential exposure.

Your company should have a clear process for reporting security incidents. Make sure you know who to contact before an incident occurs.

Remote Work Security Requires Everyone’s Attention

Remote and hybrid work provide flexibility, but they also extend an organization’s security environment beyond the traditional office.

Employees can help reduce risk by using strong authentication, keeping devices updated, securing home networks, recognizing phishing attempts, protecting physical equipment, and following company security policies.

Businesses should also provide appropriate security tools, employee training, access controls, monitoring, backups, and incident-response procedures.

Cybersecurity is not a one-time task. Threats and technology continue to change, so organizations should regularly review their security practices and make improvements when necessary.

If you are unsure whether your business network, devices, or remote-work environment are properly secured, working with a qualified cybersecurity professional can help identify potential weaknesses and determine appropriate security improvements.
