Network Security
Network security solutions protect organizational assets by detecting threats, enforcing policies, and preventing unauthorized access. We explored the key tools and approaches used to secure networks in diverse environments.
Top 10 Microsegmentation Tools in 2026
Microsegmentation divides networks into controlled segments, limiting the spread of breaches. We researched 11 microsegmentation platforms, verifying vendor claims against official product documentation, cross-referencing release notes, and field notices.
9 Real-life RBAC Examples in 2026
Role-based access control (RBAC) is the dominant access management model in enterprise IT. 94.7% of organizations have used RBAC at some point, and 86.6% still consider it their top access control model as of 2026. Yet most published material treats RBAC as a theoretical framework.
Key Components of Firewall Compliance: Guidance
Cyber attacks are projected to cost nearly $16 trillion globally in 2029. These highlight the importance of the compliance to industry-specific security policies to strengthen cyber security. Firewall compliance with industry standards like ISO 27001, GDPR, NIST, SOX, and NERC CIP ensures that organizations meet regulatory requirements and mitigate the risk of cyber incidents.
Top 8 Open Source RBAC Tools in 2026
Based on GitHub activity, update frequency, and deployment model, I listed the top 8 open-source RBAC tools that help organizations restrict system access by granting users permissions and privileges. This list covers 8 open-source RBAC tools across three categories: general-purpose authorization libraries and identity platforms with RBAC support, and Kubernetes-specific permission tools.
Demilitarized Zone (DMZ): Examples & Architecture
A Demilitarized Zone (DMZ) network is a subnetwork containing an organization’s publicly accessible services. It serves as an exposed point to an untrusted network, often the Internet. DMZs are used across various environments, from home routers to enterprise networks, to isolate public-facing services and protect internal systems.
Top 5 Network Security Policy Management Solutions
I have identified the top 5 NSPM solutions, multi-vendor and vendor-native tools, based on my & other users’ experiences and vendor features.
Top 10 Open Source Micro Segmentation Tools in 2026
Traditional network segmentation doesn’t work for microservices. IP addresses and ports can’t protect API communications when services spin up and down dynamically across containers. Large enterprises running microservices architectures need different approach: identity-based segmentation that follows services wherever they run.
6 Network Security Use Cases
Network security statistics reveal that cyber-attacks affected 350+ million individuals in the U.S. In this article, we explore network security use cases and real-world examples , from detecting insider threats to managing privileged access. For more on network security: 1.
