If data is indeed the lifeblood of any organization, then there is no greater risk than having sensitive data accessed or stolen by unauthorized users, particularly those with malicious intent. Most organizations focus on protecting data that’s stored on devices, a hard drive or even in the cloud. But hackers aren’t just trying to break into your network. They’re trying to exploit vulnerabilities in your network connections, as well as those used by recipients of your emails, so they can intercept your sensitive data. 

Protecting data at rest is important, but it’s not enough. You also need to protect data in transit so that you can share confidential information via email without the risk of inadvertent or malicious leaks. Your network may be secure, but you can’t guarantee the people receiving your information are using a secure network. That’s why every organization should be using email encryption. 

Email encryption encodes your message so unauthorized users can’t read its contents.  If you accidentally email financial information, intellectual property, customer records and other sensitive data to the wrong person, that information won’t be exposed. Only authorized users are provided with instructions for securely retrieving emails and their contents.

Traditional email encryption solutions were complicated to set up and use. You either had to use server-to-server Transport Layer Security (TLS) or Public Key Infrastructure, which added management responsibilities to the IT team’s already full plate, or you required email recipients to download special software. IT would have to be well-versed in encryption methods and manage encryption keys to ensure the solution was working properly. As a result, many organizations chose not to adopt email encryption, and those that did often failed to use it correctly.

Mimecast’s email encryption solution provides reliable, secure encryption without the complexity of traditional solutions. Mimecast email encryption is a cloud-based service that requires no additional hardware or software to be purchased and installed. Users can send and receive protected emails without downloading software or dealing with encryption keys. Emails are automatically encrypted based on administrator-defined policies involving the recipient, the recipient’s domain, keywords in the subject line and other criteria. 

Emails and files are automatically uploaded to the secure Mimecast cloud, where data loss prevention policies are applied and all content is scanned for malware. You can also create controls for email expiration dates, read receipts, access revocation, and restrictions on replying, forwarding and printing. When an email is received, the recipient is given instructions on how to retrieve the message and related data through a secure web portal.

Mimecast Enterprise Information Archiving stores multiple encrypted copies of email and files in geographically dispersed data centers to ensure security and availability. Policy-based TLS can also be used to enforce TLS encryption for SMTP over the Internet. Mimecast Secure Messaging allows you to send encrypted emails even when TLS encryption is unavailable. Users simply initiate encrypted emails in Outlook for Windows, Mimecast for Mac, or the Secure Messaging web portal. Email can then be accessed from any device through a web portal, and data never leaves the Mimecast cloud.

ICG offers secure, cloud-based email services based upon the industry-leading Mimecast platform. Let us show you how Mimecast email encryption overcomes the complexity of legacy tools to provide you with simple, reliable data protection.
