    Microsoft
    Microsoft Defender for Office 365 is found to be well suited for our size company, and easily for smaller or larger companies as well. It does have a few places where improvements can be made, but at least it also asks you to provide feedback to Microsoft, which I have done with certain suggestions or complaints. However, overall it is a very thorough and useful tool when it comes to securing and defending yourself against trending threats.

    RMail is great for sending emails with information that is sensitive but that the recipient is not going to put a lot of work into retrieving. I do psychological evaluations for criminal courts and I use it to send reports to courts and attorneys. I need to use something compatible with HIPAA privacy rules, which courts and attorneys are typically not as concerned about. If they had to use a password or go to an outside web address to retrieve the email, they wouldn't do it. It's also common for an attorney to say they didn't get an email, but I always know if they did or not, and I have clear documentation of it, which is important in legal cases.

    Pros
    Microsoft
    • It has been seamlessly working for us. We have not faced any issue as an end user. I've not faced many issues around accessing my apps, securely accessing and I've also seen certain links being blocked if I do not have correct access based on the security level that is defined for each user.

    • Read receipts tell you the time a message was actually opened
    • The electronic signature feature is nice, and usually not included with these types of services
    • Many times, a recipient doesn't need a password to open their email. RMail leverages TLS technology in most cases
    • Recipients do have the option of creating an account, but generally they don't need to
    • Outlook integration is very easy to set up
    • Gmail integration within Chrome is pretty amazing

    Cons
    Microsoft
    • I think it needs to be tuned correctly. For example, afterwards I tried to go in and print once after the implementation was done, I went in and tried to print a file or export a document. Just not possible, which just means it's great, works really well, but it also means that you have to tune your data categorization very carefully.

    • Program plug-in crashes on occasion.
    • Issues can arise if your computer's clock is not synced to RMail's time servers.
    • Setup was initially tedious (but has gotten much better since 2019).

    I don't think RPost has any competition, at least none that I can use. I think that once registered email becomes widely accepted (someday soon?), it will be indispensable for anyone in business, and RPost is the leading vendor (maybe the only vendor).

    It is as simple as downloading a plug-in or installing a chrome extension, then you click a button to use it. The interface is straightforward.

    Support is easy to access via email or phone. They also reach out to you periodically with new features, but they aren't intrusive about it. I usually appreciate it when I get an email from RMail, which is not very often.

    Sentinel One. Well, we have two different products at the same time. Just see which one is the best fit for our business. So nowadays we're using both at the same time.

    RMail is really useful when wanting to send important encrypted information, and have control of what happens on the other end. It also comes with a complete set of features that help in any other way you can imagine. I've been through other products, and nothing compares to it.

    Return on Investment
    Microsoft
    • The positive aspect is the security of the employees, security of the data. There is no breach I can say. So it is a good impact. I mean there is not any bad or negative impact.

    • There's not much ROI, because we don't get it much cheaper than the list price.
    • However, being able to offer this service strengthens our service offerings.
