According to Rod Stuhlmuller, VP of solutions marketing at Aviatrix, the company utilizes native cloud platform features and its own technology to give businesses a centralized look into the security of their cloud workloads and the flexibility to send out the same guidelines to different clouds.
"The architecture is really what's new, not necessarily the capabilities of each of the features[…]It's very different than having to reroute traffic to some centralized inspection point for whatever security capabilities you're talking about — that just becomes very complex and expensive to do," he said.
According to a survey by Flexera, “Flexera 2023 State of the Cloud Report,” a vast majority of companies (87%) have switched to a multicloud architecture, with the majority (72%) adopting a hybrid strategy that integrates both private cloud infrastructure and public cloud services. According to Flexera, managing multicloud architectures and securing cloud infrastructure are among the top concerns for businesses, with 80% and 78% of them grappling, respectively.
Security may suffer if businesses distribute workloads among numerous cloud service providers (CSPs). According to Patrick Coughlin, vice president of technical go-to-market for Splunk, a data and insights cloud platform, companies may rapidly lose visibility into the security of their cloud infrastructure because CSPs handle security policies, traffic inspection, and workload deployment differently.
The Multicloud Security Mess
Initially, many providers built virtual versions of their firewall appliances and used them as entry points to cloud infrastructure, but John Grady, principal analyst for cybersecurity at Enterprise Strategy Group, says that managing those virtual firewalls has gotten harder, especially when using multiple cloud platforms.
"Virtual firewall instances have been around for a while, but there's been an acknowledgement over the last couple of years that these deployments can be complex and cumbersome and don't take advantage of the key benefits the cloud offers[…] we've seen a general shift toward more cloud-native network security solutions," says Stuhlmuller.
Finding a solution to the expanding complexity is essential as more enterprises use numerous infrastructure-as-a-service (IaaS) solutions from the leading cloud providers, Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
By employing their native security groups, Aviatrix, for instance, enables businesses to develop an abstracted policy that can be applied across all cloud platforms without the administrator having to visit each one. The number of containers and virtual machines that need to be upgraded for businesses with expanding workloads, driven by microservice-based software architecture, can soar, according to Stuhlmuller.
"It's not that we're putting firewalls everywhere, but we're putting the inspection and enforcement capability into the network into the natural path of traffic, with a [single management console] that allows us to do central creation of policy but push that distributed inspection enforcement out everywhere in the network," he says.
Forrester Research lists Palo Alto Networks, Trellix, Trend Micro, Rapid7, and Check Point Software Technologies as additional significant vendors that concentrate on cloud workload security, but with various approaches to the technologies.
