Nutanix Flow: 5 Key Features, Use Cases, and Limitations
What Is Nutanix Flow? Nutanix Flow (now consisting of Flow Virtual Networking and Flow Network Security) is a software-defined networking and security solution native to the Nutanix Cloud Platform. It abstracts networking and microsegmentation from physical hardware, protecting virtual machines (VMs) and applications across on-premises and hybrid cloud environments. Nutanix Flow is divided into two […]
12 Network Segmentation Best Practices to Know in 2026
What Is Network Segmentation? Network segmentation involves dividing a network into smaller, isolated segments to improve security and control access. Each segment acts as a separate zone, isolating traffic and restricting communication between them unless explicitly permitted. Segmented networks are easier to monitor, audit, and defend. By enforcing boundaries between different departments, services, or sensitivity […]
How Common Platform Enumeration Puts You in Control of IT Security
IT departments are managing an ever-growing number of assets, both on-premises and in the cloud. With each new tool and system comes its own naming conventions, making it challenging to track what software and operating systems are in use. Departments often use different systems and standards, leading to confusion and delays in resolving security vulnerabilities. […]
CVSS 4.0 is Coming: Is Your Organization Ready?
Security teams are inundated with alerts—dozens or even hundreds a day. How can they know which ones to tackle first? Risk prioritization is a dangerous juggling act. Without a standardized rating system to help teams assess each incoming vulnerability, organizations’ risk management would be slapdash, ad-hoc, and reliant on manual processes and inconsistent judgment calls. […]
All About Common Vulnerabilities and Exposures (CVEs)
In September 2023, an announcement went out: Chrome, Firefox, Edge, and Safari all contained a vulnerability that left them open to attack. But even before the security community found out about the vulnerability, it was already being exploited in Chrome and Safari. That means attackers had also discovered the vulnerability and had started using it […]
TLS 1.2 vs 1.3: Why it’s Time to Switch
The internet is the world’s fulcrum point of data and communication, which makes the decision between TLS 1.2 and TLS 1.3 a vital consideration for uncompromising encryption security. Some 95 percent of all Google traffic today is encrypted, with many still deciding whether to switch from TLS 1.2 to TLS 1.3 as they weigh the […]
Lateral Movement in Cybersecurity: Understanding and Preventing Attacks
What Is Lateral Movement? Lateral movement in cybersecurity refers to the techniques used by attackers to move through a network after gaining initial access, aiming to access high-value targets like sensitive data or critical systems. It’s a crucial phase in many cyberattacks, allowing attackers to expand their reach and impact. Key aspects of lateral movement […]
Network Detection and Response: An Essential Part of IT Security
What Is Network Detection and Response? Network Detection and Response (NDR) is a cybersecurity solution that monitors network traffic to identify malicious activity and respond to threats. It uses machine learning and behavioral analysis to detect suspicious patterns and anomalies that may indicate cyberattacks, even those that bypass other security tools. NDR solutions provide visibility […]
What is Microsegmentation? 2025 Guide
The idea behind microsegmentation is to segment the enterprise network based on workloads. This type of logical breakdown of workloads allows companies to define appropriate data security policies, security services, and data management based on the use cases and needs of each workload. The microsegmentation methodology can classify the segments in different ways. Techniques include […]
How Network Microsegmentation Can Protect Data Centers
Those who still rely on perimeter controls to protect their data centers probably already know that their security solutions are in need of updates. In this post, we will look at why network segmentation through VLANs or traditional firewalls is insufficient for today’s hybrid and dynamic environments, the trend of adopting micro-segmentation as a popular […]
