Every day, your employees share information with customers, send financial documents, and transfer files online. But what if someone intercepts that information while it’s being sent?
If sensitive business information isn’t properly protected, it’s at risk. Network encryption helps keep this information unreadable to anyone who shouldn’t have access.
Let’s look at why network encryption matters and what steps businesses can take to protect data as it travels across their networks.
What Is Network Encryption and How Does It Work?
Network encryption is a security method that protects information as it moves through devices on a network. It uses encryption keys to turn readable data into an unreadable format. Without the right keys, no system can decrypt and read the information.
For example, if an employee sends confidential information through a secure channel, the data stays protected while it’s being sent. If someone intercepts it, they can’t read it without the correct key.
Why Is Network Encryption Important for Businesses?
Businesses send sensitive data over networks every day. Network encryption helps prevent unauthorized access to this data as it moves through the network.
1. Protects Customer and Employee Information
Businesses regularly share customer names, contact details, payment information, and employee records. If this data is breached, personal information could be exposed. Encryption keeps sensitive data unreadable without the right keys, protecting it as it moves between devices, offices, and online systems. The FTC’s cybersecurity guide for small businesses also recommends encrypting sensitive information sent outside the company.
2. Lowers Data Exposure Risk
Hackers may try to intercept data moving through networks. If the data isn’t encrypted, it could be readable. Encrypted data is much harder to use without the keys. However, encryption alone can’t stop all cyberattacks, so companies still need other security measures.
3. Makes Remote Work Connections Safer
Employees may use home, café, or shared networks when working remotely or in the office. Using an encrypted connection helps secure information sent between their devices and company systems. This is especially important when accessing internal files, customer data, or company applications from a distance.
4. Supports Data Protection Requirements
Depending on your business type and location, laws like GDPR or HIPAA may require you to protect personal information. Encrypting data as it travels through your network helps meet these security requirements. However, encryption alone doesn’t guarantee legal compliance.
How Can Businesses Encrypt Their Network Connections?
To protect information sent over a computer network, businesses should use secure connections and keep their network settings up to date.
Use Secure Websites and Applications
Choose websites and business applications that use “HTTPS.” This keeps information private as it travels between the site and your browser, using TLS encryption. Check for “https://” at the start of the address, especially when logging into customer records, making payments, or entering confidential information.
Protect Remote Connections With a VPN
Remote employees may need secure access to company systems. A business VPN creates a safe connection between their device and a VPN server, helping keep information secure while working remotely. However, a VPN should not replace strong passwords, secure apps, or updated device security.
Secure Office Wi-Fi and Company Devices
Protect your office Wi-Fi with WPA-AES (2 or 3) encryption. Use a strong Wi-Fi password and only allow authorized staff to access it. Keep routers and other devices updated with the latest patches. Set up a guest network to help protect business systems.
Conclusion
Network encryption helps businesses protect sensitive information when sharing it online. Using secure websites, encrypted remote connections, and safe Wi-Fi reduces the risk of data exposure. Regularly check your network security and keep systems updated to protect customer, employee, and company data.
