Q: Why aren't you using Firefox Send anymore? It is safe and easy to use.
A: Firefox Send was indeed a secure and easy-to-use service. Unfortunately, unscrupulous users abused it to ship malware and conduct phishing attacks, so it was discontinued September 17, 2020. It is no longer available to upload or receive files.
Q: Why can't I use email to send my files?
A: Sending large files via email is a big problem. Because sending large files through email can cause problems for an email system and degrade performance, IT administrators usually set limits on the size of files that can be attached to an email. To work around mail size limits, users often turn to third-party solutions for sending large files. This in turn often creates issues with security, compliance and archiving policy. The State's Mimecast Large File Send provides a solution that enables users to easily and securely send and receive large files and do so in compliance with State and HED security and archiving policies.
Q: How does Mimecast Large File Send work?
A: Mimecast Large File Send is a cloud-based service that lets HED staff send and receive files securely from their Windows or Apple computers. Large File Send enables users to send or receive files up to 2 GB in size without putting a burden on email infrastructure. Mimecast automatically uploads the file attachment to the secure Mimecast cloud, where it is scanned for viruses and for compliance with content policy. Attachments are then stored in a secure AES encrypted archive. Mimecast then provides the recipient with information for how to log onto a secure web portal to access and download the file, and how to send large file back to the recipient if desired.
With Mimecast, large files are kept off of email servers, helping to improve performance and enables IT departments to improve security and content control.
Q: How does sharing large files work with Mimecast?
A: With Mimecast, HED and other State staff can easily let contacts outside the organization know how to send a large file to them, with the added security of an access key if desired. External contacts can be shown how to send a large file via a secure web portal where they can upload files individually or in bulk with a simple drag and drop. Once files are uploaded to the Mimecast cloud, they are scanned for security and stored in the Mimecast archive where they are available for download by HED or other NM State users.
Q: I don't like using Mimecast. Is there an alternative way to securely share files?
A: Yes. The State offers Accellion Kiteworks. It can be used to securely send and receive large files, but only by way of HED or State staff; they are the ones who must initiate the sending or receiving of files. It is located at https://kiteworks.doit.state.nm.us. For detailed usage instructions, please read https://kiteworks.doit.state.nm.us/sw/guide/Accellion_Getting_Started_Guide.pdf.
