In 2020, Paul Barrett, Chief Technology Officer of Enterprise at Netscout, discussed the company's data model and the impact of the COVID-19 pandemic on enterprise VPN usage. He described Netscout's data model as having multiple levels, including the storage of raw packets and rich data related to individual transactions, and noted that for most network protocols the company can map data to a common model, allowing insight into different applications and protocols in a single pane of glass. Barrett stated that Netscout services the largest and most complex organizations in the US and globally, and that for many of these organizations, VPN services were originally designed for a small subset of the workforce. Barrett explained that the shift to widespread remote work created challenges, as many organizations' VPN configurations were not architected for the sudden increase in demand. He distinguished between full VPN connections, where all internet traffic goes through the enterprise network, and split VPN connections, where only business service traffic goes through the VPN. Barrett said that a lot of energy had been put into providing visibility around VPN services, which had previously not been seen as a critical component. He also noted that customers were thinking about future needs, such as split VPN migration and over-provisioning, and that organizations that had already transitioned to virtualized infrastructure were in a stronger position to adapt.
“A lot of energy has been put into providing that visibility around VPN services because quite honestly it was never seen as a particularly critical component of the overall enterprise. It was that kind of, oh, that's just something to help the guys on the road and all of a sudden it became the most important piece.”
“It's also not just been about giving sufficient visibility for you to keep the wheels on the truck; it's also helping the customers think forward about planning, like split migration, split VPN, but also thinking about their future needs.”
“A lot of customers are looking to over provision, and the ones that have already transitioned to virtualized infrastructure are actually in a stronger position because they've got a lot more flexibility and ability, for example, to spin up more VPN resources or more virtual desktop resources.”
“With NETSCOUT we service the largest, most complex organizations both in the US and globally, but for many of these organizations, the VPN services they provided really was for a quite a small subset of their workforce, people working on the road, maybe they had a small subset of their employees working from home.”
