I am presenting a video showing how Duo can be used as second factor authentication (push app notification in this case) for VPN remote access connections.

In this blog post, I am sharing a video showing how to use Multi-Factor Authentication for RDP (Remote Desktop) sessions. We’ll use Cisco Duo Security as the second factor (push app) authentication method. This recording was prepared for one of our Grandmetric Tech Meetings. Lab schema:   RDP and second factor authentication live demo   […]

We’ve been bringing the tech trends to the readers of our blog, by continuing to write on certain topics (like 5G, SD-WAN, Wi-Fi networking). As a summary from 2019, we have compiled here a list of the 5 most popular posts from our website.

In following post I will discuss the concept of Identity based networking and its components based on Cisco Systems products. Then I will show the steps how to build functional network where pxGrid is one of the core protocols used.

On 8th of October 2019 we hosted first event from the new series: Tech Meeting Series. The conference cycle is intended for IT departments, engineers and IT managers who want to follow latest technology trends, want to talk about the technology with others, share experience and look for solutions best suitable for their organizations.

We are very proud to announce that Grandmetric successfuly delivered the first Software-Defined production network in quarter 1 2019 for Pfeifer & Langen Polska S.A. The implementation was part of network and IT operations optimization project for one of the largest sugar manufacturer in this part of Europe.

Specifically, the paradigm called data, control and management plane dissagregation and network automation. Here, you can read about paradigms and characteristics that the SDN idea brings. Dissagregation approach simplifies the process of building & maintaining something called network overlay. Overlay is an abstraction that SDWAN idea relies on (you will read more on dissagregation and overlay concepts below).

Recently i was asked to advise in the following scenario: VPN tunnel between AWS VPC and Cisco IOS routers on DC prem. Nothing sophisticated but: Two ISR 4k, HSRP VPN redundancy, legacy crypto maps in production (several working vpns) and Static VTI (AWS). Two Crypto structures sourced from one HSRP. I have put the results on blog.

This post is dedicated to provide an overview of the Viptela policies. We go into the the details of the various kinds of policies and the overall policy architecture. In our earlier post we had focused on Viptela concept, Viptela SD-WAN components and how to authenticate the vEdges to Viptela cloud and setup basic connectivity between sites.

This post provides introduction to Smart Cities including: definition, drivers for smart cities, use cases, components of smart cities, challenges, and Telecommunications Service Providers (TSPs) Value Propositions for smart cities.
