Proofpoint Essentials offers a fully compliant and secure archive. It automatically stores copies of all email correspondence within an organisation in a secure archive, where they cannot be altered or deleted. There are configurable retention policies for email, and audits around who has accessed the archive. End users can access their own archives to view their own correspondence, which can help to reduce the burden on IT. However, emails are only archived for 10 years, which can cause a problem for businesses in the long term. If a SMB wants to keep data for longer than ten years, they may need to switch to new provider, potentially incurring a high fee.
