SNMP (Simple Network Management Protocol) and Netflow are both popular protocols with admins, prized for their ability to give visibility over the network and in some cases discern the cause of network performance issues, network bottlenecks, system resource allocation issues and more. On the Netflow side of things, third-party software vendors like ManageEngine can greatly enhance the usability and capability of the protocol, while SNMP network monitoring applications like PRTG, Solarwinds or alternatively open-source Observium, Nagios and LibreNMS take the lead in delivering a comprehensive in-depth network and system monitoring solution.
Unfortunately, however, the close relationship between the two protocols, especially when it comes to software offerings, has birthed some misconceptions. While it’s common to see SNMP and Netflow as more or less interchangeable, there are some significant and key differences between the two that make them suited for very different use cases.
Let’s take a quick look at what we’ve got covered in this article:

The Simple Network Management Protocol (SNMP) surfaced as early as 1988, with its roots in its predecessor, the Simple Gateway Monitoring Protocol, which was defined in 1987. SNMP was born out of pure necessity – before its existence, network admins didn’t have much visibility over their infrastructure at all. After the crash of the ARPAnet, on the 27th of October 1980, and as the number of complex components in networks began to snowball, it was clear a solution was needed.
However, though SNMP was initially built by a group on university researchers as a temporary solution, it quickly evolved, has remained very relevant even today. It’s not considered part of the application layer of the Internet Protocol Suite and OSI model and exists across three major versions (through SNMPv1 still tends to be the most commonly used).
Though SNMP’s name suggests management, it’s more commonly used for the monitoring of different types of network equipment, both on a network and hardware level. Typically, a monitoring server (e.g Nagios, Observium) known as a SNMP Manager monitors devices on the network, with each system holding a software snmp agent that reports information back to the manager:

The hybrid work culture has resulted in workforces increasingly using their mobile devices for work, further adding to the complexity of ensuring security across all endpoints within organizations.
The majority of IT professionals believe that mobile devices are just as vulnerable to security threats as any other endpoint, making it crucial to bring them under the umbrella of management and have the requisite security measures applied.
Tune in to this joint webinar by ManageEngine and Samsung to learn how you can apply enterprise-grade security on all your Knox capable devices, and centrally manage endpoints from one single console.

Global connectivity is top of mind for many IT teams at organizations of all sizes. We are currently in the middle of a dramatic shift in business and technology practice, as users are becoming more mobile while applications are being transitioned to the cloud. This shift will only accelerate as companies will look to leverage the speed and agility of cloud services with the operational, cost and quality advantages of a geographically distributed work force. While Covid-19 has contributed to the acceleration of this shift, the change was always inevitable once technology was ready. Legacy connectivity and security products have long been a barrier to progress.
Topics Covered
With uncanny timing, Gartner introduce the Secure Access Service Edge or SASE near the end of 2019, just before the Covid-19 virus started to gain global traction. SASE represents the shift away from castle & moat security with resources siloed into just a few corporate datacenters. After all, if organizations are consuming collaboration and productivity tools from the cloud, why not security and connectivity too?
While there is much buzz around SASE with security and networking vendors, and some debate over what products and services fit the SASE moniker, the intention is simple: leveraging economies of scale, organizations should purchase SASE as a cloud delivered service with global presence that brings security closer to the user. The user can be remote, mobile or in a corporate owned facility, regardless of physical location, the user’s access and security posture should remain consistent.
Figure 1: Cato PoP Map (click to enlarge)
At Cato Networks we built the first SASE solution, starting way back in 2015. We’ve grown to 70+ Point-of-Presence (PoPs) globally that fully converge networking and security into a single platform. With our experience we believe that a global private backbone is an essential component of a true SASE solution. If we consider that the goal is consistent access and security with reduced cost and complexity, we must recognize that the ability of a user to access resources applies not just to access controls and services, but also to the usability and reliability of that user’s access. Essentially –users must have predictable performance to be productive.
Reliability and predictability of connectivity isn’t a new concept or focus area for technical teams. Organizations have been using MPLS and other methods to achieve this for years. But MPLS is expensive, resulting in reliable, low bandwidth links to just a few places. Don’t forget that this approach completely neglected remote users who traditionally have had to VPN across the public Internet to reach datacenter security and resources.
Fast forwarding to today, most SASE vendors position their services as a way to reduce or eliminateMPLS, but completely ignore the unpredictability of the public Internet. Cato’s service was architected with this in mind, and we connected our PoPs with a global private backbone of multiple tier 1 providers. Our customer’s packets aren’t taking the cheapest possible route across tier 3 providers, instead taking the most efficient route to the destination. Combined with our WAN optimization capabilities, Cato ensures reliable, predictable performance for all users and locations.
This article explores the need for Secure Access Service Edge (SASE) in today’s organizations. We show how one of the most advanced SASE platforms available, combines VPN and SD-WAN capabilities with cloud-native security functions to quickly and securely connect On-premises data centers, cloud data centers, branch offices, and remote users.
Before we dive any further, let’s take a look at what’s covered:
IT and security managers are constantly concerned by the different entities which connect to their networks. Keeping track of who is connecting, using which edge device type, what they’re connecting to, and which permissions they should have can be a messy and dangerous business.
An enterprise’s network is composed of several types of edges. An edge can be any location or endpoint which needs to connect to any other resource or service available inside or outside the network. This includes the enterprise’s on-premises headquarters, branch offices, data centers, mobile users connecting remotely (e.g. their home), public cloud data centers (e.g. AWS and Azure), 3rd party SaaS applications (e.g. Office365 and Salesforce), and virtually any website across the WWW.
To enable connectivity and secure access for all edges, enterprises are forced to adopt different solutions to manage different edge types. For example VPN for remote users, on-prem Next Generation Firewalls (NGFWs) for the physical locations, cloud-based NGFW for cloud-based applications, Cloud Access Security Brokers (CASB) for SaaS and Secure Web Gateways (SWG) for web access. This large number of different products introduced unwanted complexity, inefficiency, and potential security loopholes to enterprises. But perhaps there is a better way to enable secure access to any service from any edge? In fact, there is, and it’s called, surprisingly enough, Secure Access Service Edge (SASE).

SASE is a new architecture that converges networking and security into a holistic, unified cloud service. It is a concept defined by Gartner in late 2019 to simplify enterprise networking and security. At the heart of the SASE premise lays the understanding that network and security cannot be addressed separately, using different products and services. The inter-dependency between the two is fundamental, and their convergence is critical for addressing the needs of the modern digital enterprise.
