What is a Site-to-Site VPN

Easily integrate a unified security solution across your organization’s cloud-hybrid network with the Perimeter 81 Site-to-Site VPN.

Site-to-Site VPNs are established by connecting two gateways in separate locations via the internet, private networks or outsourced networks using IPsec. They allow organizations of any size to easily and safely access their IT resources, whether hosted locally or in the cloud. The primary purpose of a Site-to-Site VPN is to provide secure access to sensitive assets and network resources including internal customer and sales systems, SaaS applications, and local file storage for employees accessing them from different devices and potentially unsafe Wi-Fi connections.

Seamlessly integrating with major cloud providers such as Amazon Web Services, Salesforce, Microsoft Azure, and Google Cloud, the best Site-to-Site VPNs offer organizations a scalable way to connect low-latency remote offices. Employees can connect to the tools necessary for their roles whenever and however they like, simply by logging into their Site-to-Site VPN solution via a web, desktop, or mobile app before being granted access. The encrypted IPsec tunnel between their chosen device and the network allows them to browse the web and work safely.

What is the Difference Between a Site-to-Site VPN and a Remote Access VPN?

Virtual Private Networks were introduced nearly 30 years ago when Peer-to-Peer Tunneling Protocol was first invented. Now, enterprises can take advantage of the same basic concepts but have begun to consume this utility as a service, rather than being required to install VPN hardware on-site before seeing value. This transformation is a weight off IT teams’ shoulders, as they can easily integrate a complete Site-to-Site VPN service across their entire network without complex installation, configuration, or expensive hardware upkeep. Onboarding, management, and network visibility are easy with a single admin panel, and the VPN provider is responsible for all patching and maintenance.

IT teams can now focus on more productive tasks as IT managers have found Site-to-Site VPN solutions a crucial cost-cutting tool. By hosting their organization’s VPN with a high-quality third party provider, an organization’s CTO can easily budget for their team and expect a stable, secure, and low-latency experience for remote workers. With a predictable subscription-based model, transparency about what kind of hardware the provider uses and where it resides geographically, and the logging policy, it’s easy to predict a specific quality of service.

A Remote-access VPN gives employees access to secure connections with a remote computer network for accessing network resources as if they were directly connected to the network’s servers. Though some organizations might still prefer Remote-access VPNs, given that despite their high costs, these VPN solutions provide greater control, the variety and quality of modern Site-to-Site VPNs match alternatives. With the rise of the mobile workforce and cloud transformation, there is an increased adoption of remote workers and many companies are moving to cloud infrastructures. 

In the best Site-to-Site VPN examples, clients can anticipate a dedicated, highly qualified support staff and a global array of server nodes that mean faster connections anywhere. They’ll also have granular details of hardware performance and encryption provided, not to mention a Site-to-Site VPN that is more scalable and supports various Site-to-site VPN protocols.

What is the Difference Between a Site-to-Site VPN and a Point-to-Point VPN?

Site-to-site VPNs securely connect corporate networks with remote offices to communicate and share resources as a single network. Organizations sometimes use site-to-site VPNs for private traffic instead of using MPLS. A site-to-site VPN bridge helps to provide access and enterprise-class encryption over secured and encrypted networks.

Since site-to-site VPNs create private tunnels between a user’s device and the remote network. These services offer encrypted tunnels between a user’s computer and a server to anonymize traffic and protect organizations from attackers. For instance, they allow users to bypass geographical restrictions on streaming content.

Point-to-Point VPNs work similarly, but instead of connecting to a server and relaying your traffic, the service maintains a direct connection within a network. In other words, Point-to-Point VPNs place resources entirely in the domain providing the VPN.

A Point-to-Point VPN relies on a circuit-switched network for access control and data transport between two networks. If the endpoint doesn’t have a public IP address, the server can route traffic through the physical network on that server and back out to the public internet.

How Does a Site-to-site VPN Work?

Site-to-site VPNs grant the employees of an organization secure access to its resources: cloud-based SaaS applications, files and data storage, and more. To gain network access, employees must open their Site-to-Site VPN application on their computer’s desktop, web, or smartphone or tablet. Afterwards, the VPN establishes a secure connection using site-to-site Internet Protocol security (IPsec), which resides in Layer 3 of the Open Systems Interconnection (OSI) model. IPsec works for remote access and network-to-network deployments to spin up encrypted tunnels between peers sending data to one another.

On Internet Protocol (IP) networks, cryptographically secure IPSec security keys create a protocol for clients to authenticate their communications at the beginning mutually and during a session. Company VPN types, such as Cloud VPN, Site-to-Site VPN, and VPNaaS enable two networks to be connected as if by a hardware router. IT managers can also delineate specific rules and network policies across local and cloud environments, which is accomplished more quickly through the client rather than time-intensive configuration.

Why Switch from a Consumer VPN to a Site-to-Site VPN?

These days, it’s somewhat challenging to find an organization that doesn’t have a cloud-hybrid network, and this alone justifies the need for a Site-to-Site VPN rather than a traditional VPN. Over 96% of organizations have incorporated some cloud-based platforms into their general business flows, whether applications, file storage, or other crucial systems that keep the business in the black. Additionally, the onset of 5G has encouraged organizations to allow for more remote work and Bring Your Own Device (BYOD) policies. This has changed the shape of the modern network perimeter significantly, and demands that IT teams install a thorough, holistic network security solution covering this more numerous and diverse endpoints.

The VPNs invented decades ago are not compatible with this reality. Though they are still somewhat relevant and indeed provide encrypted access, the effort and money required for them to conform to modern hybrid-cloud networks is an enormous obstacle. There’s also the idea that traditional VPNs allow users the freedom to roam all corners of an organization’s network, lacking built-in segmentation and policy-based access management capabilities necessary to reduce insider data breaches. Unfortunately, these occur more than ever, representing a problem for compliance-focused organizations.

Regardless of intentional insider data breaches, the number of remote workers, devices, and improperly secured public Wi-Fi sources creates further gaps in business network security. The only way to combat the risks when an employee works from a cafe, for example, is to rely on user-centric security solutions rather than perimeter-centric ones. Site-to-Site VPNs and business VPN solutions focus back on the users navigating through a network and do away with the idea that once someone has access, they’re trusted with every resource they can access.

Parting with the notion of security, Site-to-Site VPNs are also lauded for their cost-efficiency and ability to boost productivity. Site-to-site VPNs offered as a service offer seamless onboarding, omnipresent network visibility, lower latency, and other more favourable benefits regarding scalability. Regarding brass tacks, migrating from a traditional VPN solution to a Site-to-Site VPN is a foundational step in instituting a hard-line, agile network security policy.
