Does SSL matter? It does and it’s not just web encryption.

Posted on September 4, 2019September 4, 2019 by Percy Kwong

Over the last decade, there’s been an ever growing emphasis on security.  SSL is taking a seat “Front-Row center” on this period of enlightenment.  Interestingly enough, it’s not just about encrypting your traffic on the web.  The purpose of this is far deeper.  This article will delve into the “why” SSL’s importance has grown and…

VOIP Tunneling with SBO or OpenVPN?

Posted on June 29, 2012 by Percy Kwong

There seems to be much talk these days of tunneling and Voice-Over-IP(VOIP) most of it for the singular purpose of keeping the communications secure or hidden from the nasty overlords of the Internet.  There seems to be two camps in this and two main technologies.

Posted on June 17, 2012 by Percy Kwong

I’m at the point where I can’t support this blog due to the traffic I’m getting.  I really need some donations or something.  I’m pushing about 5 GB of data a day and due to my divorce, I can’t afford to support this continually. I’m not asking for donations, although, they would help, but I…
