So those not accustomed to how Microsoft do acquisitions it kind of goes like this:

1. Offer made

2. Accounts and business reviewed in detail, final price agreed and purchase completed - regulatory approvals etc

3. Business is run as a subsidiary of Microsoft

4. Products go through the security development lifecycle so it is ensured they meet the standard Microsoft security policies and procedures

5. The Microsoft brand is then given to the business and the product appears on our price lists so our usual channels can access the tools and sell the product in the usual fashion
