Company is a unique way to build continuous improvement into an organization and ultimately reduce IT problems over time. has designed a technology recipe for reducing per capita problems to keep staff productive. It's also focused on Orange County, so its just down the street. As an MSP in Orange County, I am very concerned about network security for small businesses. Many small business owners do not know how vulnerable they are to cyber security attacks. Since the weakest link in a company's network security is actually its own employees, business owners need to enhance their employees security training. To shed light on this issue, we have started hosting network security training events throughout Orange County and are now hosting them via live webinar. Our first security-focused lunch and learn took place near the end of February and was a huge success.

In today’s day and age, to be successful and get a leg up on the competition, most businesses need to consider themselves a technology company first. The mindset for this would follow the formula of: “We are a technology company that…” for example: “We are a technology company, that works on mechanical engineering projects” or “We are a technology company that helps design and build office spaces.” The businesses that adopt this mindset will excel in the near and long-term future, as technology helps them become more agile, efficient and effective at everything they do. However, this becomes another thing to worry about for business owners and partners. Although we are now exposed to technology every day in our homes, it can be overwhelming to think about it in our business lives as well, especially when the stakes in a business setting are a lot higher. The goal of MSP 3.0 is to help business owners of Architecture, Engineering and Construction firms, stop thinking and worrying about technology-related issues and focus more on their business. To have more time and do things they love to do most. We become your fully staffed IT department at a fraction of the cost of hiring internal technology talent. You will get every IT department position, from desktop support to systems administrator, to CIO. Your organization will need these roles at various times, and you will get them on demand, and for one nominal monthly fee
