Network Security

Report

All the internet content you read, send or receive carries a risk . The internet, e-mail, and instant messaging are standard in today's workplace. As a result, network security and inappropriate usage concerns are now bigger than ever for all San Francisco Bay Area businesses. Firewalls, passwords and encryption alone can't protect you.

My main computer wasn't turning on today. I'm so glad I contacted Computer Service Group. They responded quickly. They offered to come to SF to pick my computer since they're in Brentwood for a few, however that wasn't necessary as they gave me a solution over Yelp That I was not aware of and that advice was free of charge. This is the type of businesses that make a difference! Don't hesitate and call them also to fix yours. Thank you for your help!
