In-House Vs Hosted Email Security

Introduction

Software as a Service (SaaS) has quickly become the standard delivery model for critical business IT software and services. Business customers realize many benefits by leveraging SaaS services. The On-Demand model of SaaS infrastructure provides benefits to the customer by lowering their overall costs, while increasing flexibility, reliability, and overall solution security. However, as new businesses begin to evaluate SaaS software and services, many still have concerns about security, fearing that hosting their critical business applications and data with a SaaS provider will expose them to greater risk and loss of control. This concern is particularly acute for businesses' messaging and collaboration needs around email and instant messaging. As business email is now a primary method of inter- and intra-corporate communications, including the exchange of sensitive financial data and intellectual property, businesses are growing increasingly concerned about the need for secured email and messaging services. Microsoft Exchange is the leading business email and collaboration solution for the small, up to the large, business markets, and this whitepaper compares the security of Microsoft Exchange Services deployed in-house versus a hosted model with SaaS service providers. By choosing ReadySpace as their Hosted Exchange SaaS Solution Provider, businesses can achieve email and total messaging security, as well as a piece of mind, by leveraging ReadySpace's infrastructure and experience with running a secured messaging platform.
