Posted by Daniel Noworatzky on Jul 22, 2020 10:39:00 AM

Common Wi-Fi security threats and how to mitigate them

Posted by Daniel Noworatzky on Aug 21, 2019 10:49:00 AM

Wi-Fi itself should not be feared as a technology susceptible to network attacks; it is a flawed implementation that should be feared. Because of the nature of the technology, Wi-Fi signals can be easily intercepted by any wireless device within range. Nevertheless, with the proper security precautions in place, these intercepted signals become useless to even the most determined attacker. By employing industry-standard security measures, Wi-Fi becomes an enterprise-grade high-performance solution suitable for almost any application.

In this article, we examine the the most pervasive threats to Wi-Fi networks and the best ways to mitigate them.

Three reasons you should never use a free VPN

Posted by Guest Blogger on May 10, 2019 10:44:00 AM

By Chris Jones, #TurnOnVPN

In the age of relentless internet surveillance, using a VPN has become mandatory for anyone who values their online privacy. Between your internet service provider storing your entire browsing history and third parties planting “cookies” (data trackers) all over the websites you visit, you leave a considerable digital footprint whenever you surf the web. This intimate data is then sold to advertisers so they can better target online ads.

These growing privacy concerns made VPN incredibly popular. VPN (Virtual Private Network) encrypts your network, making it impossible for third parties to access and collect your browsing data. Widely available and often free, VPN seems to be the perfect solution to guarding your internet privacy.

But as Kenneth White, an internet security expert, revealed to CNN Business, "there is a long history of 'free' VPNs that prey on innocent consumers' concerns about security and cynically make them less safe.” Here are the three main dangers related to using a free VPN service:
