For the times of coronavirus (COVID-19) pandemic, Grandmetric has setup VPN as a service hub. If your company is lacking VPN SSL licenses, IPSec VPN performance, VPN appliances or simply enough knowledge, your employees can easily connect to Grandmetric VPN Hub

25th of February took place our Grandmetric Tech Meeting #2 titled Enterprise Connectivity & Data Center. This time, after great feedback from attendees of Tech Meeting #1 where we focused on Enterprise Security aspects, we decided to present the connectivity and DC technologies behind the slogans: SD-WAN, MFA, Hyperconvergence, VXLAN and EVPN DC. We carefully selected materials and speakers to provide highest quality to the audience. Tech meetings are mostly about technologies and almost no marketing. Our speakers are experienced engineers, architects or managers to deliver knowledge in the best way and of best quality.

As for previous years, 2019 abounded with the different types of events for Grandmetric crew. This post reminds the Grandmetric events tour in 2019 chronologically. We also projected our presence and initiatives for the 2020 so we lift the curtain a bit in this post.

We are glad to announce that our new bootcamp: Cisco SD-WAN Training is fully prepared, available and ready to deliver.
