5 Major Benefits of VPN (Virtual Private Network)
- Enhanced Online Privacy and Anonymity
- Secure Web Browsing and Online Transactions
- Bypassing Geographic Restrictions
- Prevent Throttling and Reduced Internet Speeds
- Remote Access for Employees
1. Enhanced Online Privacy and Anonymity
One of the main reasons people use a VPN is to protect their online privacy. VPN services allow users to browse the Internet anonymously by masking their real IP address and replacing it with one leased from the VPN provider.
Without a VPN, your ISP can easily monitor all your online activities and even sell this data to advertisers and other third parties. A VPN prevents the ISP from logging the websites you visit and creates space for anonymous internet access.
VPNs route the user’s internet traffic through an encrypted tunnel before exiting onto the public Internet. This prevents the ISP from monitoring or recording the user’s browsing data. The VPN assigns a new virtual IP address each time the user connects to their service.
The user’s real IP address and location are hidden. This makes it much more difficult for websites, advertisers, and other third parties to track online activities or create user profiles for targeted advertising.
Using a public Wi-Fi network is highly risky without a VPN. Other users on the same network can easily intercept transmitted data and steal login credentials, financial information, and other sensitive data. A VPN encrypts all network traffic and prevents MITM (man-in-the-middle) attacks on public Wi-Fi.
Many people also use VPNs to access blocked websites and services anonymously without being identified. In regions with strict internet censorship, a VPN can help citizens bypass government restrictions imposed on access to certain sites and online content.
2. Secure Web Browsing and Online Transactions
VPNs are essential for securing sensitive online transactions, such as banking, shopping, insurance policy management, etc., against hacking and identity theft. VPN encryption prevents cybercriminals from gaining access to personal and financial data as it travels across the web.
Public Wi-Fi networks in airports, hotels, cafes, and other locations are notoriously easy for hackers to penetrate. Connecting to the Internet using these hotspots without a VPN is strongly inadvisable. Encrypting traffic with a VPN ensures nobody can intercept transmitted data or passwords when using any untrusted connection.
Government agencies and ISPs that have deep packet inspection capabilities can very easily extract personal information like usernames, passwords, credit card numbers, etc., from internet traffic. A VPN adds an extra layer of security through encryption that prevents this by limiting what the ISP can see.
VPNs also protect against DNS leakage and IPv6 leaks, which could potentially expose the user’s real IP address and location. VPN services include firewall protections to prevent such leaks, ensuring that all internet traffic is anonymous for maximum privacy.
Utilizing a VPN secures online activities not just on laptops and smartphones but also on internet-connected home devices. Internet of Things (IoT) devices like smart TVs, digital assistants, Wi-Fi cameras, etc., can compromise user privacy. Connecting them through a VPN adds an extra layer of security.
3. Bypassing Geographic Restrictions
VPNs allow internet users to bypass location-based restrictions imposed on online content. Streaming platforms like US Netflix, Hulu, BBC iPlayer, etc., have geo-restrictions that limit content availability based on the user’s geographical location.
By connecting through a VPN server located in a different country, users can easily access international content catalogs on such services. This technique allows expats and travelers abroad to view content from their home country as well.
Many news and media websites also impose geographic restrictions on online content. Changing one’s virtual location using a VPN helps access this blocked content from anywhere in the world, which is very useful, especially when traveling internationally.
Government censorship of internet access in some countries can also be bypassed using a VPN. The Great Firewall in China notoriously blocks access to websites like Facebook, Twitter, Google, and various foreign news outlets. Citizens use VPNs to circumvent these barriers.
By selecting a VPN server near the game server location, gamers can lower ping times and latency issues when playing on international servers. This gives them a competitive edge against players in other regions.
4. Prevent Throttling and Reduced Internet Speeds
ISPs often throttle bandwidth-intensive online activities like streaming HD video and downloading large files through torrent clients. This results in very slow internet speeds. VPN encryption prevents ISPs from recognizing the type of traffic and selecting it for throttling.
Without a VPN, an ISP can easily figure out when a user is streaming movies or gaming online and deliberately slow down the connection speed. This forces users to upgrade to more expensive packages for faster Internet. A VPN secures your connection against such throttling practices.
In regions with internet censorship and restrictions, governments actively throttle access to banned websites and online services. A VPN masks internet traffic, making it impossible for authorities to identify and slow down access to particular sites or web-based services.
Gamers in many countries suffer from ISPs’ intentional throttling of online games. Using a VPN often improves ping, reduces lag, and offers a much smoother online gaming experience. The encryption prevents ISPs from throttling gaming servers.
5. Remote Access for Employees
Many companies use VPN solutions to provide employees with secure remote access to internal company networks and resources. This allows staff to work productively when traveling or based out of home offices.
Client VPN software creates an encrypted tunnel from the employee’s device to the corporate network. Remote desktop access allows users to use company apps, tools, files, and databases securely over the Internet.
VPNs enable secure collaboration between employees in different locations through a shared virtual network. Sensitive business data can be transmitted safely without the risk of interception by cybercriminals.
IT teams also segment the corporate network to control remote employee access to only specific sections or resources for enhanced security. Access permissions are configurable to prevent unauthorized access.
Multi-factor authentication is used along with VPNs to add an extra layer of protection for remote access. One-time passwords and biometrics like fingerprint scans prevent unauthorized logins even if the VPN credentials are compromised.
VPN Use Cases & Scenarios
Let us look at some important use cases and scenarios where using a VPN provides immense value and benefits:
- Secure Public Wi-Fi Access
- Bypass Internet Censorship
- Online Anonymity
