What is Azure VPN, and how does it work? – TechRadar

Microsofts Azure VPN (opens in new tab) offers two kinds of products: Point-to-Site (P2S) and Site-to-Site (S2S). Site-to-Site VPN is a form of cloud VPN, while Point-to-Site is an example of remote VPN. For a refresher on the two product types, you can read our comparison piece,.

Azure VPN will encrypt your corporate network communications with military grade AES-256-bit encryption, regardless of which product you choose. This level of security ensures that your sensitive corporate data remains safe while in transit between networks, or to and from remote workers PCs.

This article will discuss the appropriate use cases for each Azure product, describe their unique features, and explain pricing and customer support options.

If you've ever worked from home in an office setting, you probably used Point-to-Site VPN. P2S VPN encrypts communication between remote workers' devices and your corporate server by creating a secure communication corridor called a tunnel.

Tunnels encrypt information at one end, then decrypt it at the destination. This allows remote workers to safely access business apps and sensitive customer information from home. P2S VPN tunnels are temporary, and can open or close as required, when employees log on and off from the corporate network.

Site-to-Site VPN works quite differently. It also creates a tunnel, but the tunnel is always active and optimized for large volumes of data. These permanent tunnels can send large volumes of encrypted information back and forth between two or more corporate networks. An example of two sites that need to communicate this way could be a head office in New York communicating with a satellite branch in LA, or two corporate head offices in Europe and Asia exchanging information.

Which of these products makes sense for you will depend on your business needs. A group of geographically remote research sites with a central database and only in-office staff may need a Site-to-Site VPN. In contrast, a small business with just one location but several remote workers may opt for Point-to-Site. You will need both if you run a large enterprise with remote staff and multiple branch offices.

When selecting a corporate VPN, there are many options for both Site-to-Site and Point-to-Site solutions. For instance, in addition to Azure, Perimeter 81 (opens in new tab) and Amazon AWS VPN (opens in new tab) offer both product types.

Azure VPNs products have many advantages over the competition. Firstly, Azure doesnt charge upfront for the use of its VPN gateways. S2S and P2S VPNs use a VPN gateway to encrypt and decrypt communications. Some gateways can handle Site-to-Site connections, while others are designed for Point-to-Site. How many connections a gateway can handle and what type varies by provider.

Many VPN providers charge a flat fee per VPN gateway, and an additional per-hour cost based on usage. Azure charges are purely by the hour. Additionally, Azures gateways can handle P2S and S2S connections, offering even more flexibility.

Azures pricing is per hour and based on the size of the VPN gateway you need. Gateways can create Site-to-Site and Point-to-Site tunnels.

For P2S connections, remember that the number of tunnels can fluctuate throughout the day, as various devices connect and disconnect. Be sure to buy a big enough gateway to handle your traffic at peak time. Otherwise, employees may have trouble logging in during the busiest time of the day.

Consult the chart below for an overview of Azures pricing. Note that although prices are shown by the hour, Azures billing is monthly, billed on the day of the month that you activated your account.

As you can see, pricing varies considerably based on the number of connections you need, and the amount of data going through your system at any given moment. Pay attention to your bandwidth needs, the number of remote employees you have, and the number of Site-to-Site connections you have to establish.

Azures Basic customer support package, included for all customers, provides access to the self-service knowledge base and support ticket system. There are no guarantees for response time on support tickets on the Basic tier, and Basic support customers are last in line behind all paying support plan holders.

Limited free support is normal for cloud VPN providers, and Azure stands out by simply having a free support option that isnt entirely self-service. Paid plans start at $29/month for trial and non-production environments, and go up to $1000/month for one-hour critical case response time, plus a dedicated consultant.

Azure offers two powerful cloud-based VPN solutions for Site-to-Site and Point-to-Site VPN. Its scalable pricing, with no upfront fees for gateways, and 99% uptime on P2S systems, allows for an impressive degree of flexibility when building a P2S, S2S, or hybrid solution.

Azures customer support options are limited and expensive, but this is normal for a cloud VPN provider. If you need encrypted access for remote employees, or want to securely connect a set of remote networks together, Microsoft Azure VPN is a robust option.
