What is SD-WAN?

For a quick SD-WAN definition, know that it stands for a software-defined wide-area network, which is a virtualized network that is abstracted from datacenter or branch office hardware to create an easily configurable and scalable overlay wide area network distributed across local and global sites. It’s also an application of Software Defined Network (SDN) technology that is more reliable and scalable than VPN-based WAN solutions because it takes a software-based approach to building and extending enterprise networks beyond the core SDN.

Organizations today can use SD-WAN vendor solutions to connect branch offices to their corporate networks instead of using traditional and expensive multiprotocol label switching (MPLS) connections, firewalls or proprietary hardware. Integrating with major cloud providers such as Amazon Web Services, Salesforce, Microsoft Azure, and Google, the best SD-WANs offer organizations a scalable way to connect remote offices.

What is the Difference Between SASE and SD-WAN?

Secure Access Service Edge (SASE) is a new model for network security that is shaping the way organizations will secure their networks and data in the upcoming years by combining network and security when integrating networking and security stacks into a single unified platform. The rity functionality into a unified global cloud-based service. SASE and SD-WAN go hand in hand. The key aspect is SD-WAN security service that operates as the backbone of the SASE model.

SASE platforms also provide organizations IT agility and reduced complexity by consolidating multiple security functions into a single secure network for access to multi-cloud resources. SASE solutions combined with SD-WAN technology transforms network security into an easily consumable service with reduced cost and management overhead while providing a scalable cloud-based network infrastructure service.

How Does an SD-WAN Work?

SD-WAN virtual appliances, connected by encrypted tunnels, connect to sets of network services that provide enhanced functionality across the virtualized network. Moreover, traffic reaching an SD-WAN appliance can be classified based on application or service type which is then prioritized using centrally-managed policies to optimize network traffic.

Well-built SD-WAN architecture provides IT administrators with the ability to integrate network infrastructure and security controls together that range from internet traffic prioritization and content filtering to firewall creation and threat management, all via a web portal.

By eliminating the need for expensive and proprietary networking hardware gear, SD-WAN technology reduces the physical infrastructure overhead so that any organization, from small and medium businesses (SMBs) to enterprises, can quickly deploy highly secure networks either locally or globally.

SD-WAN vs. VPN

VPNs are a vital part of network security, and enable the encryption of traffic over the network and to the web. Organizations’ networks can extend off-site and to remote users without fear of being exposed, since the connection is private between the device and the network. VPNs therefore prioritize traffic encryption and have little to do with how efficiently resources themselves are connected.

SD-WAN vendors are able to help organizations that adopt the cloud and strive to better service new branches and offices around the globe. Using a VPN alone to securely connect employees to resources isn’t effective and due to a lack of cloud nativity and edge presence, will likely result in higher latency and connectivity issues. SD-WAN for enterprise enables them to pursue the optimal path for network performance and security in tandem, by reducing reliance on hardware, aligning better with cloud tools, and converging with security ideas.

Why Switch to SD-WAN?

Although SD-WANs virtualize connectivity via encrypted cloud tunneling, security best practices must also be taken into consideration as local and global endpoints send and receive traffic via the public internet. SD-WAN misconfigurations remain a risk that could lead to data breaches and data interception by malicious third parties.

Most major cloud application platforms such as Microsoft 365 and Salesforce can be accessed from branch offices or via remote workers directly from the internet with strict IAM policies and services such as Azure AD. However, untrusted cloud apps and suspicious web traffic with unknown security configurations need additional traffic inspection. SD-WAN enabled broadband routes on the public Internet also represent a higher level of security risk versus MPLS network connections from single carriers.

With well-architected SD-WAN policies and procedures in place, organizations can route trusted business application traffic across the public internet while sending social network and video content to a cloud-security service for malware inspection. Additional untrusted or suspicious traffic from a foriegn country or peer-to-peer application traffic can also be routed to a next generation firewall for filtering, for instance.

Secure Access Service Edge (SASE) security solutions combined with SD-WAN technology provide additional levels of protection and security functionality that may include secure web gateways (SWG), cloud access security broker (CASB) capabilities, firewall as a service (FWaaS) functionality, and Zero Trust network access (ZTNA) for secure network access in cloud and mobile environments, both locally and globally.

Why Switch to a SD-WAN?

Protect Your Organization’s Resources

Total Endpoint Encryption

IPsec tunneling protocols establish a secure connection between users’ devices and network resources, as soon as they log into the cloud VPN client. This ensures that only authorized users and devices can connect.

Low-Latency Remote Work

Full access for remote workers includes the ability to connect from anywhere and at any time, and share data securely. Those with the ability to connect are already authorized, so oversight is kept to a minimum.

Easy Cloud Integration

One of the biggest advantages of an SD-WAN is that they’re cloud-friendly and cloud agnostic, meaning they can seamlessly integrate with the most popular products like Salesforce, AWS, and others.

Highlighting the Benefits of a SD-WAN

Combined with SASE our SD-WAN Consists of 4 Primary Capabilities

Unified Network Platform

One cloud-based platform capable of access management, monitoring, permissioning, and other IT necessities.

Multi-Tenant Cloud

Divide the network into segments according to your security policies. Segregation protects network resources.

Easy to Use Clients

Support for 2FA and single sign-on across mobile devices using iOS and Android, PC and Mac desktops and the web.

Zero Trust Access

Requiring both user and device authentication, this multilayered model hinges security on users, not perimeters.

What Perimeter 81 Offers Your Organization

Security on All Devices

BYOD policies multiply the number and variety of devices connecting to your network. SD-WAN allows authorized, secure access for all devices and remote workers no matter the details.

Cloud Agnostic Integration

The ease with which an SD-WAN integrates into any cloud-based platform or service (as well as local environments) enables organizations to protect all their resources in a unified fashion.

Superior Quality Assurance

Connecting to the Business VPN through a diverse global server array helps the QA and marketing teams determine how best to target different markets, and how successful current efforts are.

Safe Remote Access

Automatic Wi-Fi security lets remote workers connect to sensitive resources from the public internet without fear of exposure, while encrypted tunnels shield data sharing from prying eyes.

Precise User Segmentation

Beyond the capabilities of traditional VPNs, the addition of granular policy-based permissioning helps organizations exercise greater control over those entering their network.

IP Whitelisting

Explicitly define the IP addresses that are allowed to access the network, granting IT teams a stronger grip on security and also the ability to assign static IPs to automatically trusted sources of traffic.
