A virtual private network (VPN) creates a secure private network across the Internet and enables your employees to safely send and receive data as if their computers or phones were part of your organization’s private network. For example, your employees should use a VPN to protect their email or web browsing while outside the office, such as working remotely from home or traveling for business.
A VPN helps safeguard your employees’ transmitted information by establishing a virtual point-to-point connection through the use of encryption, dedicated connections and virtual tunneling protocols. Any applications or resources that your employees access remotely via a VPN have the same functionality, management and security as those inside your private network.
Two Basic Types of VPNs
Managed site-to-site VPN: A service provider securely connects your company’s main office and branch locations using a VPN via the service provider’s network or the Internet.
Managed remote-access VPN: A service provider securely connects remote workers and mobile workers to their corporate network using a VPN via the service provider’s network or the Internet.
Both site-to-site and remote-access VPNs achieve the same overarching goal: They safeguard your company’s business data.
Why We Need VPNs
It is extremely difficult for a nation-state, cybercriminal, or other bad actor to breach a properly managed VPN and steal valuable information such as passwords, credit card numbers and proprietary business data. As businesses, governments and others become more sensitive about data breaches and the other dangers posed by unsecure networks, they are investing more in VPNs. Globally, the VPN market is forecast to reach $70 billion in 2019, up from $45 billion in 2014, according to Statista’s market research.
