![]() ![]() SASE can dynamically allow or deny connections to services and applications based on an organization’s defined security policies and access rules. SASE secures each device and performs networking decisions to direct traffic from different applications to different users as efficiently and securely as possible. The distributed access points avoid latency problems through short-distance connections to high-speed networks. SASE vendors provide points of presence (PoPs) worldwide using the cloud or SD-WAN technology. Secure cloud-based assets such as applications, websites, and Software-as-a-Service (SaaS) resources usually using SWG, FWaaS, or web application firewall (WAF) capabilities.Control access to data and resources based upon user, device, and permissions usually using ZTNA, SD-WAN, or CASB capabilities.Inspect traffic to block malware and malicious URLs through a centralized control and filtering usually through a SWG or Firewall-as-a-Service (FWaaS) capabilities.Monitor user activity and provide data loss prevention (DLP) analysis usually through CASB or NGFW capabilities.Monitor network status and provide reports on performance and security.Centralize control through a cloud-hosted, centrally managed solution and a single software interface.To be considered a SASE solution, the vendor must provide the following solutions: These variances can cause confusion regarding the definition of SASE, yet the core definition remains intact: SASE secures remote resources through integrated management services hosted in the cloud. Fortinet excludes CASB from their definition of SASE because they do not offer a CASB solution.Cloudflare excludes SD-WAN from their core security components of SASE because they do not offer a SD-WAN technology.In practice, various SASE vendors will emphasize their specialty, such as networking or cloud access, in their definition of the technology to provide their solution with advantages. The “edge” refers to the hardware device (data center server, laptop, IoT) directly connected to the internet where it might be exposed to attack. Gartner coined the term SASE (pronounced ‘sassy’) in its Future of Network Security in the Cloud report published in 2019 and defines SASE as converged network and security capabilities that incorporate technologies such as software defined wide area networking (SD-WAN), cloud access security brokers (CASBs), secure web gateways (SWGs), next generation firewalls (NGFWs), and zero-trust network access (ZTNA). SASE provides an edge security solution that addresses these challenges without the bottlenecks of traditional virtual private network (VPN) solutions. This trend spreads out data center risk over the internet and increases the potential vectors for attack. The trends to adopt Internet of Things (IoT) devices, remote work, and cloud resources drastically increase the amount of communication outside of the traditional network that needs to be secured.Īdditionally, operations bottlenecks lead IT departments to move storage and processing functions closer to the edge of the network to avoid performance hits for users or data center overload. Traditional networking either causes operations bottlenecks by forcing all traffic to route through centralized firewalls or exposes remote assets and cloud resources to attack. Bottom Line: Implement SASE to Improve Security and Operations.We will explore SASE in more detail through the following topics: ![]() Large, sprawling organizations need this type of technology because they often struggle to apply consistent security policies outside of their network to remote workers accessing cloud-hosted resources, branch offices, and edge computing. Secure access service edge (SASE) provides an integrated service solution to secure large virtual networks that encompasses users and resources no matter where they are or how they access each other.
