Working remotely or from a home office has become the standard mode of operation for most businesses. While some users may base themselves from the office, there is the flexibility to complete the majority of today's working week everywhere from the user's house to the local cafe and even via wireless aboard aircraft.

In addition to users, IOT (Internet of Things) has also become part of your remote workforce as devices connect, retrieve and upload data to cloud infrastructure. The result is a shift from the branch office WAN edge to the user-office WAN edge which could be located anywhere at any time from any device.

The onus is on the Enterprise IT team to consider how SD WAN remote access can deliver both application performance and SASE security. Whether the remote work is carried out using browser access or connection via software client, applications are positioned to utilise SD WAN functionality and features such as path selection and WAN optimisation.

In this article, we discuss the top features IT teams must consider together with an overview of 5 remote access vendors.

What are the main SD WAN remote access features?

  • Browser or client access zero-touch SD WAN deployment - out-of-the-box connection to application in minutes via zero-touch deployment downloadable client software or direct access to resources via browser remote access. With client installation, pre-configured access templates can be delivered based on user type, reflecting the level of data and application need. Secure remote access via a browser is typically limited to web-based company resources.
  • Active directory - the majority of remote access authentication occurs via active directory authentication. The fast setup of synchronisation is the enabler to quick deployment of remote network access with full control via your SD WAN management interface.
  • Multi-factor authentication with a single sign-on - the typical enterprise business is partnered with an identity provider for single sign-on (SSO) and strong authentication. When evaluating new remote access products, consider how automatically integrating with identity providers will enhance security and ensure the user is familiar with their sign-in process.
  • Real-time inspection of remote traffic - Secure SD WAN SASE offerings will support NGFW (Next-Generation Firewall), Secure Web Gateway (SWG) with threat protection technology from Intrusion Protection Service (IPS) and Managed Detection Response (MDR). Remote access is an extension of SD WAN capability and therefore, full SASE should be available whether the user is based remotely or from the branch-office.
  • Application performance treatment - SD WAN capability varies across applications treatment features. With selected vendors offering access to private global IP backbone connectivity, global Internet gateways or pure end to end Internet, there's a decision to be made on which solution best fits your business requirements. In the majority of cases, SD WAN vendors will offer path selection with local QoS (Quality of Service), WAN optimisation and path selection to improve network performance with diversity to maintain uptime to avoid packet loss.
  • Cloud unified remote access management - in order to gain insights into remote user performance, manage permissions and create new security policies, the SD WAN solution should offer a unified cloud management approach.
  • Business continuity DR planning - remote access positions all team members to work remotely if the situation arises. IT teams are advised to check whether any prospective SD WAN solutions are BCP (Business Continuity Plan) ready.

Remote SD WAN user

Accessing coprorate resources originates from multiple devices including business supplied devices and BYOD (Bring your own device).


The Enterprise is adopting Internet SD WAN technology as the enabler to public cloud application access with SASE security. With users working remotely from home offices, the WAN edge is no longer with branch or HQ. One recent survey suggested that new employees often start their career working from home, meaning the Enterprise must offer good performance and security. Selecting an SD WAN vendor to replace MPLS or facilitate new requirements is critical to get right to ensure users can both access the corporate network and public cloud providers such as AWS, Azure and Google. Selecting and implementing the right remote secure access solution is key to the success of your organisation.
