Intradyn works well for a small to medium business like ours that just needs to keep an archive of every email sent or received throughout our organization. It's easy to search for emails, whether you're looking for keywords, sender, recipient, subject, body, header, etc. The Outlook plugin works well for end users.
Proofpoint Intelligent Compliance is well suited for organizations with a large amount of employees, in my opinion, as they have a lot of options for grouping users in various ways to send specific learning content to them. For a smaller organization, the employees might utilize all of the built-in training videos, phishing simulations, and content more rapidly, which would not justify the pricey cost of the tool.
Email archiving. Being able to access, on the fly, your entire email archive. Being able to filter by date, sender, attachment, etc. It can get really granular and is able to pull up records fast.
Targeted Attack Protection for all incoming emails. Having the ability to automatically scan, quarantine, or re-write URLs within emails. Comparing incoming emails to potential phishing attempts already seen by other institutions.
Email encryption & automatic encryption are based on certain rules set up on the firewall. e.g. automatically encrypt outgoing email if it has an attachment or contains a string of numbers that may be personal information.
Outlook plugin is great, but I wish it could somehow update user passwords when users change them via Active Directory. In our environment, users have to change their AD passwords every 45 days, but the Outlook plugin doesn't capture the change, so the next time the user tries to search the archive via the plugin, the plugin doesn't work. Since our users aren't accessing the archive that often, they easily forget that they've changed their password since they last accessed the archive and need support.
It's hard to compare Proofpoint archiving and compliance to the rest of these products because I personally feel like they all integrate so well with each other. Using them all simultaneously creates a completed puzzle for our company that gives our users the power and the protection they need to stay safe in a world where threats are always around every corner. I can easily recommend the four Proofpoint products above and they all work well together.
Eventually, we will be consolidating our archives into this solution. Having all archives in one location (from various migrations over the years) will cut down on admin time for legal matters, as well as not having to worry about duplicate emails from different archives.
Admins will not have to search for emails that users deleted or can't find and now need. They can find their own emails.
We can grant access to our legal team to run their own search and gather projects, which takes a decent amount of time off IT admins' plates.
