A lot of computer work can be crisis-oriented especially if your network is down and your email’s down and so you are sort of panicked. And to have them come in, they’re calming, and they’re captivating. It gives you a sense of confidence and you don’t see that a lot in the industry.

I have known J Chun for almost 20 years. He was head of IT for our investment management company, in charge of all systems and communications, and performed admirably.

Both he and his associates are first-rate technicians, and great people also.

Wireless networks or technologies have allowed businesses & organizations to become more mobile. However, a poorly secured wireless network is particularly vulnerable to security threats & accidental intrusion. Our solutions are designed to enhance both of its security.

I highly recommend them. Knowing they'll be there for us 100% as we change and grow gives me peace of mind. So glad they've got our backs!
