I have a client that needs to secure her medical transcripton business.
I am looking at sonicwalls and need to know which one would be good for voip.
I have worked with sonicwalls for many years but never set one up for voip.
I have worked with the tz170 standardand enhanced. I also have worked with the tz180 wireless standard
My client uses vonage as her voip carrier.
Currently she is using the windows firewall to secure her systems and a linksys router.
She recently got the anti-virus 360 spyware program on a system and I had to clean it off for her. I scanned all her other systems and found some other malicious programs. Which I cleaned with malware bytes
I believe implementing a sonicwall along with avg free will take care of her security.
She has one 2003 small business server, 4 xp pro workstations and one laptop.
Any advice or other alternative security measures would be appreciated.
