View Aryaka SD WAN strengths and focus areas on the vendor marketplace. View Aryaka now →
Aryaka, which was arguably the original NaaS (Network as a Service), has evolved a multifaceted portfolio around core connectivity, cloud interconnect, security and network analysis services. The company’s NaaS service, which includes core SD WAN features, called SmartConnect is available with either global or regional connectivity with global private backbone access. Users access their local private PoP using DIA (Direct Internet Access). To this, Aryaka developed the following complementary services:
- SmartCloud, a multi-cloud backbone with direct connections to AWS, Azure, Google Cloud and Oracle and accelerations for SaaS (Software as a Service) applications.
- SmartSecure, a SASE tier with a integrated advanced security firewall, micro-segmentation and remote access VPN.
- SmartOptimize providing WAN and acceleration across cloud applications
- SmartManage and SmartInsights WAN infrastructure management portal and APM
Aryaka recently acquired Secucloud which adds their own SASE security capability to their SD WAN solution. If your business is reluctant to move away from private based, QoS (Quality of Service) enabled MPLS circuits, Aryaka is worth considering as a good half way networking and security capability.
What are the PROS of Aryaka SD WAN?
- Multi-cloud access to AWS, Azure and Google Cloud
