A comprehensive guide to Check Point Network Address Translation (NAT), covering concepts, configuration, automatic and manual NAT, static and hide NAT, ARP, NAT tables, and best practices. Designed as a definitive learning resource with practical examples, troubleshooting tips, and advanced scenarios for real-world deployments.

Let's discuss the natural evolution from just getting things working to adding all the bells and whistles, a Flannel to Cilium discussion, powered by eBPF, as the logical next step for Kubernetes networking. Looking at how Isovalent Enterprise enhances scalability, security and observability, offering a robust, production-ready platform for complex, multi-cluster environments. Transitioning to Cilium signifies embracing advanced capabilities for modern network engineering.

Quantum computing's rise threatens classical cryptography, prompting urgent shifts to post-quantum cryptography (PQC). Check Point leads this transition with quantum-ready solutions, ensuring secure communications through hybrid key exchanges and cryptographic agility. As PQC standards evolve, Check Point's architecture promises seamless adaptation, safeguarding digital infrastructures against future quantum threats.

Not just a single solution, a zero trust implementation is an integrated approach for continuous validation of authorized users across your entire organization. A zero trust security framework focuses on protecting critical assets through a layered, continuously monitored and adaptable architecture that minimizes risks and containment in case of breaches.

Fortinet XPERTS 2025 delivered the heat, despite the cold outside. Packed with cutting-edge innovation, expert insights and hands-on learning, this year's event proved once again that Fortinet knows how to bring the fire to cybersecurity.

K-12 and library network and wireless systems need enhanced segmentation through modern infrastructure today more than ever! In my post, I provide some clear reasons and guidance on enhancing these critical infrastructure components. I explain why it is important to implement new modern infrastructure underlay and overlay systems and what they can do to help enhance the security of staff, students and xIOT components on the supported network systems.

As cloud-native technologies continue to converge with traditional networking in the data center and enterprise, understanding how Kubernetes, Cilium and eBPF works is crucial for network engineers. With hybrid mesh firewalls being the latest trend, and distributed firewalls (like Cisco's Hypershield) emerging in the market. Understanding how Kubernetes transforms traditional IP networking concepts into a dynamic, software-defined environment is crucial. This article demystifies Kubernetes security, making it accessible for network engineers familiar with ACLs and VLANs. You may think this doesn't apply to you, but if you're planning a firewall refresh anytime soon, then these concepts will need to be part of your vernacular going forward.

Hardening your core routing protocols, such as ISIS, OSPF and BGP, is one of the simplest and cheapest ways to immediately improve your security posture. This post explores practical steps to secure routing adjacencies, filter route updates and reduce overall exposure in the control plane of your core network.

Contact centers and voice calling have expanded the attack surface. While CISOs and cyber security leaders are doing their best to defend against bad actors, voice calling is a vulnerability that is often overlooked.
