The importance of VPN in network security

2023, Oct 25

Since everyone has been using the internet, there is a need to protect internet browser data. VPNs (Virtual Private Networks) provide an extra layer of privacy when people visit websites and provide secure connections for transmitting sensitive corporate information.

What is VPN?
VPN is an important cyber security tool that helps protect user privacy and safety online. It works by establishing an encrypted connection from your device to the network, creating a solid layer of protection. VPNs help mask your IP address, ensuring that your online activities cannot be tracked or stolen.
What does a VPN hide?
1. Equipment
Devices such as laptops, tablets, and mobile phones are often the main targets of intrusions from cybercriminals when users access the Internet, especially when they use public Wi-Fi connections. At these access points, VPNs play a vital role in protecting data on personal devices, preventing MiTM (Man-in-the-Middle) attacks from intruders.
2. IP address and location
An IP address is an important part of identifying any device on the Internet or local network. The owner of the IP address has the ability to determine the user's location and their online activity.
However, VPNs have the ability to replace the actual IP address, making it look like the user is accessing the Internet from another location, usually the location of the VPN server. This helps conceal users' physical locations and creates an important layer of protection for their online privacy.
3. Browsing history
Internet service providers (ISPs) and web browsers can track everything users do on the Internet. A cost-effective VPN service hides your IP address and prevents your ISP from monitoring any online activity. This provides a private, secure browsing experience on the internet.
Business benefits of VPN
1. Secure connection to shared resources

Many companies today must collaborate with employees located around the world, relying on technology to do this. Sensitive company data, including information about customers, employees, and business operations, is often stored on cloud services and file-sharing work applications. Using IP whitelisting on a VPN (Virtual Private Network) can play an important role in protecting connections to these critical resources and ensuring data security.
A VPN is a network security tool that can ensure that only whitelisted servers or clients can access connections to an organization's internal resources. This helps ensure that only authorized people with access can connect to critical resources, while protecting company data from potential risk.
2. Save costs without jeopardizing security
With VPN support, companies are no longer dependent on installing expensive physical network connections between headquarters and other branches. This not only helps save costs and resources, but also reduces the workload on the company's IT administration team.
For large corporations with thousands of employees and a large number of devices, installing a VPN application on each individual device becomes ineffective. Instead, IT teams can use a mobile device management (MDM) solution to automatically configure and deploy VPN applications across all devices.
Through an MDM solution, organizations have the ability to create VPN connections, custom VPN authentication, and select the appropriate server type. With Scalfusion MDM, companies also have the flexibility to choose a third-party VPN provider to best meet their needs.
3. Secure data on mobile devices
Remote workers, responding to emails and accessing files on company servers via COPE devices and public Wi-Fi connections, are at risk of being attacked by intruders. and data breaches. Bad actors may focus on attacking Wi-Fi connections to commit fraud and steal important information.
It is important to ensure the security of data on both company laptops and mobile phones. Installing a remote VPN application on mobile devices allows employees to securely connect to email applications and access company servers, creating a reliable layer of protection during work. from far away.
