Traditionally, network visibility within the WAN has been made possible by SIEM (security information and event management) solutions and network management systems that aggregate packet flow data from multiple security and network monitoring tools such as security appliances, firewalls, and endpoint sensors.

Cloud and SaaS traffic must be first brought from the branch to a secured Internet access point at central location. As such, traditional MPLS architecture find it difficult to offer low latency/high performance access to cloud and SaaS applications and services.

How will they secure all of the Internet access points created by SD-WAN? By expanding the attack surface, every office with DIA now requires the full range of security services including next-generation firewall (NGFW), IDS/IPS, sandboxing and more. Simple changes, such as firewall rules, could take a couple of days.

As I discussed in my previous blog , few companies, especially global organizations, have Internet access at every branch. UCaaS traffic must be backhauled across the WAN to Internet access point resulting in inefficient traffic routing for voice and video calls, and potential quality issues related to excessive delay and jitter.

Security meant protecting the companys central Internet access point and deploying endpoint security on clients. Once inside the enterprise, though, many WANs are flat-networks with all sites being able to access one another.

SASE SASE (Secure Access Service Edge) converges network and security functionalities into a single cloud-based solution. SASE merges the network optimization capabilities of SD-WAN with a full security stack, including Next Generation Firewall (NGFW), Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), and more.

Here’s a ridiculous list for you: Switches Routers Firewalls CASBs IDS/IPS appliances Wireless access points Public clouds Network load balancers Application load balancers Service provider networks 5G networks Data center overlays SD-WAN overlays Container network interfaces Proxies DHCP services IPAM databases …and the list goes on.

Security SD-WANs achieve significant gains in agility and cost reduction in large part due to their ability to leverage direct Internet access (DIA) at branch offices. But DIA also significantly expands the attack surface far beyond that which can be protected by the basic firewall provided in SD-WAN appliances.

Note: This environment is having firewall, switches, router, access points, etc Thank you ! I wanted to do the assessment of my branch office network from network architect perspective like, to ensure whether industry best practices are followed, is there any improvement area, etc., Is there any framework can be followed ?
