BYOD vulnerability: Based on the BYOD concept, employees use their own device to connect to the company’s network. Unfortunately, they often overlook implementing the security precautions necessary in doing so — not updating their applications, or visiting vulnerable websites, or having machines infected with malware, etc. So, once the VPN is set up, this compromised device can infect the entire corporate network. For this reason, it is advisable to connect via corporate devices, which are subject to a security policy and managed by the IT team. Compromised devices can infect the entire company network and all the assets contained therein.

Overload, slow performance and high latency: A large number of employees connected simultaneously overloads the VPN gateway, causing performance drop, activity interruptions and delivery delays.

Difficulty in adapting: When there is an unexpected increase in employees working remotely and connecting via VPN, companies need to appropriately modify the infrastructure to accommodate the number of connections. This adaptation involves purchasing, deploying and configuring additional VPN gateways. In addition to being expensive, it takes time and is complex to execute properly.

Usage problems: The VPN requires several steps and the memorization of several logins for different applications, making it difficult for employees to implement its use efficiently.

Complexity in maintenance: VPNs require an additional application for remote control; this, in turn, makes maintaining the company complex, as well as adding a potential layer of difficulty in connecting each employee.
