VPN is a workhorse of secure online connectivity. It encrypts your internet traffic and creates a tunnel so you can securely browse the internet. The best thing about VPNs is that they continuously evolve to adapt to the increasing cybersecurity threats. VPN gateway is a sophisticated form of VPN which drives an immense level of simplicity, scalability, and flexibility. Its enhanced data transmission and internetworking capabilities make it a preferred choice for both individuals and businesses. It acts as a bridge to connect two or more networks, remote sites, or devices that cater to the connectivity requirements of large businesses or enterprises.
Let’s walk through a deep understanding of a VPN gateway and explore the innovative capabilities that it has to offer.
What is VPN Gateway?
A VPN gateway can be a server, firewall, router, or any similar device that can establish a connection between two or more networks or devices in a VPN infrastructure. If a remote worker wants to access a private network, this VPN gateway acts as a gateway or entry point for them to establish a secure connection.
VPN gateway can also act as a site-to-site VPN where it connects two or more networks together; for instance, it may connect branch offices to central offices or where multiple offices work in collaboration and require a secure communication pathway.
Just like a traditional VPN, it encrypts the data in transit from one site to another over the public internet. VPN gateway uses high encryption protocols, allows multiple integrations, and is highly available.
How is VPN Gateway Changing the Game?
As compared to a traditional VPN, a VPN gateway is a much more sophisticated form of VPN that delivers high performance and efficiency. It contains high flexibility, simplicity, and redundancy. With diverse use cases and innovative capabilities, it has left traditional hardware-based
security options behind. It helps enterprises by allowing them to establish a secure connection over a public network. Similarly, it aids individuals working from home to securely access corporate resources and share sensitive information without any risks.
The key advantages of a VPN gateway involve:
VPN gateway follows a high-level encryption policy and integrates military-grade encryption, i.e., AES 235-bit encryption. Businesses and individuals who want to send critical information over the internet should keep this multi-layered encryption standard in mind. High Scalability and Optimization When choosing a VPN, users mostly opt for a VPN that supports multiple devices. A VPN gateway is known for supporting simultaneous connection and efficient distribution of resources. Likewise, it offers load-balancing features that help businesses optimize their network performance to visualize vulnerabilities and increase efficiency.
High Availability and Redundancy
Every business aims for uninterrupted connectivity, as downtime can cause significant damage. The high availability and redundancy offered by a VPN gateway help address this problem. Organizations can deploy multiple gateways in different sites, which delivers seamless
connectivity and help reroute traffic in case of network failure.
Support Multiple Protocols and Integration
VPN gateway supports different protocols such as Internet Protocol Security (IPsec), OpenVPN, and Secure Socket Layers/Transport Layer Security (SSL/TLS). This helps users choose a protocol of their choice or requirements. NordLayer’s VPN gateway service leverages the IPsec protocol that is known for offering a high level of encryption to create a secure connection between remote sites and AWS cloud services. Besides, the VPN gateway smoothly integrates with your existing infrastructure, allowing easy integration without modifications. This compatibility makes organizations easily integrate with existing network setups and draw maximum benefit from this internet-based VPN gateway.
Advancements in VPN Gateway
VPN market size is currently $1.7 billion and is forecasted to reach $7.2 billion by 2033. This high market growth is driven by innovation and advancement in this security solution. VPN markets consistently add innovations and advancements that are adding high functionality, efficiency, and flexibility to security solutions.
Quantum computing, advanced VPN protocols like WireGuard, multi-cloud and hybrid cloud environments, site-to-site VPNs, and remote access VPNs are changing the game of virtual networks. Here are a few advancements in the VPN gateway world that can make it a futuristic
Cloud-Based VPN Gateways
VPN gateways have evolved to offer cloud-based solutions. This means you won’t need hardware to deploy this solution, making it a flexible and scalable solution. Cloud-based VPN gateway adds simplified management and provides on-demand deployment, making it ideal for
organizations operating in a cloud environment. Software Defined Network (SDN) Integration VPN gateway can now support SDN integration, allowing organizations to allocate their resources more efficiently. This adds flexibility and provides much control over network
configuration so organizations can better manage their networks.
Packet Capture Filtering
Packet capture helps narrow down the scope of the problem, so you can readily identify it and take remedial actions. Besides a specific connection, you can run a packet capture on the gateway as well. This includes Internet Key Exchange (IKE), Encapsulating Security Payload
(ESP) traffic, one-way or bi-directional traffic, and inner packets coupled with filtering on a VPN gateway.
Integration with Other Security Options
VPN gateway offers a high level of flexibility in terms of establishing a connection with other VPNs, firewalls, threat intelligence platforms, and intrusion detection and prevention systems. This allows improved efficiency and security of your network infrastructure.
For instance, the VPN gateway of NordLayer VPN can be connected to other security solutions, such as Azure, Google Workspace, AWS, Okta, Google Cloud, OneLogin, and Jumpcloud.
The Multi-Cloud environment is on the rise, and many organizations are embracing it for better security and ease. That’s why the VPN gateway supports multi-cloud environments as well. This means organizations can establish a secure connection between their on-premises network and different cloud providers, enabling secure data transmission and network integration.
VPN gateway has strong capabilities in establishing a secure connection for users to transmit data and use corporate resources over the internet. It bridges the gap between two or more networks, applications, or devices with strong encryption protocols, regardless of their physical location.
VPN gateway is a viable, flexible, and scalable solution for all your security issues. Besides, it offers simplified management and high availability and guarantees a seamless integration with your existing infrastructure. Moreover, advancements, such as a multi-cloud environment, improved security protocols, and hardware-less cloud VPN gateways, are making a big difference in the VPN world. So both businesses and individuals can rely on a VPN gateway to ensure the utmost security of their critical resources.
