NetFlow is a network protocol that enables devices to report key traffic flow data such as origin, direction, and overall volume.

IT admins are expected to keep the organization’s network reliable and resilient all while the complexity of today’s networks grows. From adopting hybrid infrastructures and maintaining multi-cloud environments’ security to managing ever-increasing bandwidth demands, enterprise network management is getting more difficult by day.

Cloud security is a constant concern and tends to revolve around common themes - how do you give intended users access to the data and systems their clearance allows, while maintaining a good user experience; and how do you keep unintended users or malicious bots out? In the entanglement of systems, services, and applications that make up a modern IT infrastructure, this is a lot harder to balance in practice than it is on paper.

Cybersecurity remains a key concern for any organization. The cost of cybercrime is expected to rise to $8 trillion in 2023 and reach $10.5 trillion by 2025. Various cybersecurity solutions are available, with Firewall as a Service (FWaaS) emerging as one of the most valuable assets when it comes to protecting your interests. We will investigate FWaaS solutions, how they work, how they're different from traditional firewalls, and what benefits they can provide for a range of organizations.

Let's start by simply stating that MPLS is arguably still the leading way to interconnect remote offices back to the company’s primary data centers. MPLS is also great for real-time traffic (like video conferencing). Yet even with those facts working in MPLS’s favor, its usage is dropping year after year. According to TeleGeography’s annual WAN Manager Survey, there was a 24% drop from 2019 to 2020 – and that trend hasn’t slowed down.

Today’s modern enterprise WAN is a mix of public internet, cloud provider networks, SD-WAN overlays, containers, and CASBs. This means that as we develop a network visibility strategy, we must go where no engineer has gone before to meet the needs of how applications are delivered today.

Welcome, network admins and IT pros, to "How to Diagnose Network Problems: The Ultimate Handbook." In the digital landscape where operational efficiency is paramount, a well-functioning network is vital to your enterprise's success. However, when network problems arise, it can be exasperating, leaving you stranded in a sea of connectivity challenges.

Streaming telemetry holds the promise of radically improving the reliability and performance of today’s complex network infrastructures, but it does come with caveats. In the first of a new series, Kentik CEO Avi Freedman covers streaming telemetry’s history and original development.
