MIME 2017 Annual Report

7 We have a proven record of performing successfully at considerable scale and addressing rapidly growing customer demands. We process approximately 379 million emails per day and manage over 260 billion emails in total with our service. We archive approximately 40 petabytes of customer data and add more than 65.9 terabytes of customer data per month. We are able to provision customer email and onboard massive amounts of email data from legacy archives rapidly and efficiently. This drives customer adoption and makes the cloud transition easier than our customers typically expect. Once a customer is live on our service, adding new products to their subscription only requires activation from within their single administration console. Our Proprietary Native Cloud Architecture— Mime | OS™ We developed a proprietary operating system called Mime | OS™ for native cloud services. Mime | OS™ enables secure multi- tenancy and takes advantage of the cost and performance benefits of using industry-standard hardware and resource sharing specifically for the secure management of email and data. This enables us to provision efficiently and securely across our customer base, minimizing the impact of spare or over-provisioned processing and storage capacity, reducing the cost of providing our services. Mime | OS™ comprises 20+ microservices that control the hardware, and the storage, indexing, processing, services, administrator and user interface layers of our cloud environment. It has been specifically designed to enable us to scale our storage, processing and services to meet large enterprise-level email and data demands, while retaining the cost and performance benefits of a native cloud environment. Mime | OS™ also streamlines our customer application development and enables strong integration across our services. All of our customer applications or services use Mime | OS™ to interact with our data stores and processing technology, as well as interoperate effectively with each other. Continuous Development Methodology and Multi-Tenancy Advantage As we enhance and expand our technology, we can update services centrally with little or no intervention required by the customer, as each customer shares the same core operating and application software. Improvements, upgrades, new products or patches are applied once and are available immediately across our whole service to customers. It means we have only one up-to-date version of our service to maintain and support as well as a common data store for all customers that simplifies management, support and product development. Our services already process and manage large volumes of customer data and this is growing daily. Our commitment to continual improvement in Mime | OS™, our customer applications and hardware infrastructure mean we are constantly strengthening the performance of our service as we scale. These improvements include faster archive search times and data ingestion, greater storage density, improved processing and extended security coverage. Each week, we roll out updates and enhancements centrally that benefit our customers without the need for additional infrastructure investment on their part. Additionally, when new threats emerge, we act once by making changes to our service and all customers benefit immediately. We can also identify and act on threats to one customer and quickly prevent them from impacting others by changing our core system. How Our Services Work Mimecast Advanced Security We protect inbound and outbound email from malware, spam, advanced persistent threats, email DoS and DDoS, data leaks and other security threats. Inbound email is directed through Mimecast Email Security, which performs comprehensive security checks before the email is delivered to the customer’s email infrastructure. This prevents unwanted email from reaching the customer in the first place and cluttering their infrastructure unlike on-premises services from competitors. Each day, we monitor approximately 820 million messages and deliver, on average, less than 50% of those messages to the customer. Outbound email sent from the customer also passes through our service and is checked before being sent on to prevent it from presenting a security threat to the recipient. Outbound email can also be encrypted, and scanned by our comprehensive content controls to prevent confidential documents or data leaving the business. Data leak prevention is a key consideration for all organizations.
