What is Virtual Private Network (VPN) Software?

Virtual private network (VPN) software connects users and devices to private networks using encryption and security mechanisms. It ensures that only credentialed users have access to private networks and sensitive data, and protects data in transit, using encryption. Users of VPN software employ these tools to restrict access to corporate networks to credentialed users, protect the information they send over the internet from being accessed by third parties like hackers attempting to view confidential information, mask their IP address and location, and access geo-specific website content. VPN software has both corporate and personal use cases. Companies seeking to increase their security or restrict user access to sensitive corporate data can utilize VPNs to set up gated, internal networks. Individuals often use personal VPN software to secure their connection and encrypt their traffic when using an unsecured or public Wi-Fi network that may be vulnerable to attacks, such as those found at homes, airports, hotels, or coffee shops. VPN software works by creating a secure, encrypted connection over a less secure network, like public internet. VPN software uses VPN tunneling protocols to achieve this and encrypts incoming and outgoing data traffic. These tools also encrypt IP addresses, mask locations, and can bridge connections between devices. These products often contain firewalls to prevent viruses, hacks, and other threats. What Does VPN Stand For? VPN stands for virtual private network. VPNs are virtual because they connect users to other computers virtually. They are private because of their ability to hide a user’s IP address and encrypt their traffic data. The word network in VPN refers to the network of VPN servers accessible to the user with their VPN provider. What Types of Virtual Private Network (VPN) Software Exist? Corporate or enterprise VPN: Corporate or enterprise VPN software securely connects remote employees to corporate networks and cloud services. These tools encrypt company data traffic end to end and prevent unauthorized access to company networks. This VPN connection enables a company’s mobile workforce to access corporate email, chat, file sharing, intranet sites, and other corporate and cloud applications when working remotely. Remote access VPN: This type of VPN lets users connect to private corporate networks. This is best for organizations with a highly mobile workforce. It allows them to work as if they were in the office. Site-to-site VPNs: This VPN connects branch offices to corporate office networks. Intranet-based VPNs connect offices of the same company. Extranet-based VPNs connect to offices of an external company. Personal VPN: Personal VPNs help users access the internet when they are connected to an unsecured network to privately browse the internet. It also allows them to change their IP address to access geo-restricted websites and content.

What are the Common Features of Virtual Private Network (VPN) Software?

The following are some core features within VPN software: Strength of VPN protocol: Each VPN protocol has strengths and weaknesses related to speed, encryption, stability, streaming, and downloading. The most secure and mobile-friendly VPN connection protocols are OpenVPN and IKEv2 protocols. Strength of encryption: The most common encryption types are AES-128 encryption or AES-256 encryption, known as military-grade encryption. Double VPN: Some VPN service providers send internet traffic through two servers, encrypting it twice. Kill switch: A kill switch automatically shuts off a user’s internet access when the encrypted connection is lost, preventing data breach. Logging data: Some companies and IT administrators want to monitor VPN usage. Some VPN providers record and store user logs. No log or zero log policy: In some instances, VPN users value privacy and opt to have no user logs recorded. Some VPN service providers offer a no log or zero log policy. The VPN provider does not collect or keep any data transmitted on the VPN. Depending on the jurisdiction, there may be legal issues with no log policies. GDPR compliance: If a VPN provider keeps data logs on European Union (EU) citizens, the provider is required to comply with GDPR regulation. Desktop clients: Many VPN providers work with operating systems such as Windows, macOS, or Linux. Mobile clients: For mobile and secure VPN access, many VPN providers support Android and iOS mobile device connections. Browser extension: Some VPN providers offer browser extensions as a quick, easy way to connect to a VPN server using browsers like Chrome, Firefox, and Safari. Multidevice limitations: VPN providers may limit the number of devices, users, or businesses that can access the VPN. Most free VPNs allow up to five or six devices before they require users to switch to a paid version. High-speed connectivity and reliability: Speed, bandwidth, and reliability are important when considering which VPN provider to select. VPN providers may highlight the geo-location and the number of server switches they have, as user speeds improve when more servers are available. Malware protection: Some VPN providers offer auto installation of patches to prevent malware attacks. Zero-trust secure access: This ensures only authenticated users with compliant devices can access network applications. DNS leak prevention: This encrypts DNS queries, preventing leakages due to security flaws in DNS requests that may be revealed to ISP DNS servers. Ease of administration: People use VPN software because accessibility is important. Choosing a solution with an intuitive, user-friendly interface can help users log on to the VPN more easily. Customer service: Many free VPN providers offer no customer support while enterprise VPN providers offer dedicated customer support to help troubleshoot problems.

What are the Benefits of Virtual Private Network (VPN) Software?

With VPN software, remote employees can securely log on to their corporate networks and access the same corporate applications, folders, messaging, intranet sites, and corporate email as their colleagues at the corporate office. For an increasingly remote workforce, traveling employees and people who work from home, VPN software is a major consideration for companies to make. Benefits of using VPN software include: Remote workforce support: VPN software enables remote employees to connect to corporate networks. Secure access: VPN software restricts access to corporate networks to credentialed users and secures data sharing between offices with end-to-end encryption. Privacy: For those using VPNs for personal use, the most common reason is to mask the user’s true IP address. This helps when using public internet for privacy purposes, to access geo-restricted content, and to ensure a secure connection.
