Important CCIE Update

Cisco CCIE Training Update

This is a special notification for NC-Expert’s CCIE Candidates.

We have learned from Cisco that it expects to refresh its entire portfolio in February 2020.

We strongly urge all CCIE Candidates to prepare to complete their studies and sit their respective lab exams by the end of 2019, latest.

We understand that there will be limited opportunity for Candidates to sit lab exams in the early weeks of 2020, however these seats will be severely limited.

For candidates anticipating completing their studies, please contact us at your earliest convenience so we can conclude our part in your training.

NC-Expert cannot be held liable if Candidates choose to delay completion of their training because, at this time, Cisco has provided no information about its continued instructor-led offerings.

As a result, NC-Expert cannot confirm that it will be able to continue to offer Cisco’s own instructor-led CCIE training after February 2020.

By Rie Vainstein • July 4, 2025
Connecting the Dots? Wi-Fi Sensing just hit the headlines in a big way, reportedly as the latest technological invasion into our lives. Many people were horrified about the threat of being spied on in their own homes. In this blog, we investigate the reality of the technology and determine how far the “Big Brother” myth actually goes. Phrases like, “Your Wi-Fi can detect movement,” can strike fear into the heart, that our every move is being watched and tracked... but is it really as bad as it seems? What is Wi-Fi Sensing? Wi-Fi Sensing uses the Radio Frequency (RF) signals that are already being transmitted by Wi-Fi devices. When these signals propagate through space, they interact with everything in the environment: people, pets, furniture, walls, etc.

The Importance of Using a VPN

By Rie Vainstein • March 31, 2025
A Digital Shield for Your Online Adventures As tech professionals, we often spend a good chunk of our lives navigating the digital realm. Whether you’re troubleshooting a network, coding a new app, or just binge-watching the latest series, one thing is clear: your connection to the internet is a double-edged sword. It’s both incredibly convenient and, if not properly secured, a potential vulnerability. Enter the VPN (Virtual Private Network) our trusty, digital bodyguard. If you’re not already using one, or if you’re not entirely sure why you should, let’s walk through some of the reasons why a VPN is essential for anyone working in IT and, frankly, for anyone who uses the internet. What Is a VPN? In simple terms, a VPN creates a secure, encrypted tunnel between your device and the internet. It allows your data to travel securely, masking your IP address, and ensuring that no one (be it hackers or nosy advertisers) can track or intercept your online activity. Think of it as your personal “cloak of invisibility” in the digital world!
