Microsoft
Office everyday things since time immemorial. It's hard for Google Suite or any other to compete with Microsoft. They have everything, and it all works great, with incredible tools and capabilities. The new integrations work seamlessly most of the time, such as embedding a Power BI in a PPT. Expecting too much AI, like note taking, or LLM-based PPT, is not available in my tier at least, so depending on the budget, you won't get all you may expect from an AI leader. For diagramming and process maps, you're better off with other tools like those above.

Mimecast's advanced email security remains the number one security tool available for any organization. You will be ahead of the game before anything gets in and users start clicking. Users are often the ones who can disclose sensitive data and compromise the organization and its brand.

Pros
Microsoft
  • It allows us to keep our email organized. I like the fact that I can create folders in Outlook, and they replicate on my mail server.
  • Excellent for drafting and saving those documents as PDFs without needing PDF editing software.
  • Spreadsheets - what more is there to say?

  • Simplicity: Once set up, Mimecast Advanced Email Security is easy to use, intuitive, and simple. This reduces onboarding time with new employees.
  • Robust Audit Trail: Being able to see what happened with specific emails, why things happened, and who was responsible for them helps to reduce troubleshooting time as well as improving overall email observability.
  • Clean Interface: Mimecast Advanced Email Security is a Swiss-Army-Knife of email security. There are many different configurations and complex rules that can be implemented. To make this manageable Mimecast Advanced Email Security has implemented a simple and clean UI. Being able to favorite commonly used features makes a huge difference in usability.
  • Simple SSO Integration: This seems like a no-brainer, but its odd to see how many SaaS products either don't support SSO, or make it so complicated and convoluted that setup and maintenance becomes a fully time job.

Cons
Microsoft
  • Microsoft 365 really needs to work on protection part. In complex environment it is not reliable as compared to its competitors like Proofpoint. There are many instances where it fails to perform effectively.
  • In SharePoint Online the versioning feature of the document needs to be improved by Microsoft. Sometimes when we have to roll back to the previous version it does not work as expected.
  • In Teams messaging and app permission policies can be improved. There are some settings where we have to add a lot of things manually.

  • I would like to see some additional improvement around the attachment protection, specifically what may be getting caught and what types of files are attempting to be delivered via email by impersonators.
  • The Targeted Threat Protection is a great product, and I wish there was a dashboard for this service where we could easily see the types of emails and/or links that have been caught as part of the protection module that could be shared with executives.
  • Finally, I feel that the phishing protection is great and honestly don't believe there should be much improvement needed there.

There are many features of Office that we cannot replicate in any other tool. Plus people know it already. It's not going away anytime soon.

There is no question as to the value of the product to the business and the disruption of changing vendors would not be worth any savings possibly achieved by switching.

Usability
Microsoft
It being the default office suite means it's user experience and idioms are things that everyone is generally very used to and fluent with.
The sharing is relatively simple, being directly hooked into Entra AD, and expiry being a first class concern.
It's usability decreases at scale, with multiple people simultaneously making edits can make documents unusable.

The console is nice, but it could use some improvements for day to day activities for Admins. I find I am jumping around all over to get what I need (always searching for the right area). Being able to customize a Dashboard or having a central typical activities dashboard will be helpful to save more time.

Over the past 8 years of using Microsoft 365, I have noticed that they change vendors often. This always leads to a poor experience in the beginning, then levels out after some time for the company to get things worked out. As a customer, it is really frustrating because I don't have time when something isn't working to have them "look into my issue" and get back with me. They have even closed a ticket I specifically told them to keep open. Your applications are only as good as the support.

When calling them you get best in the world customer services but as previously mentioned their online community and capabilities are a bit lacking. They want you to log into their portal to see updates on issues (vs. using a public facing service) and I rarely find the answers to my issues in electronic format. Their online presence is only helpful with the simplest of issues.

Its very user-friendly, collaborative and efficient that boosts productivity using cloud tools. their security is strong and it provides data protection. There are regular updates that shields us from attackers too. It offers a wealth of learning resources, including tutorials, help articles and video guide to help users make the most of the application and personally upgrade their skills.

In my opinion, Mimecast Advanced Email Security outpaces Microsoft in terms of usability and reduction of spam and phishing emails. Mimecast Advanced Email Security was cheaper than Proofpoint, but I suspect Proofpoint is doing better on staying current with trends than Mimecast Advanced Email Security. I think Abnormal offers the best incoming email security, but does not offer outgoing email data loss prevention or encryption, which is a key use cast for us.

Return on Investment
Microsoft
  • It has helped keep the high-energy culture my company has since it allows easy communication and calls.
  • Positively impacts responses from clients, since we can see how many times they have been contacted. (the more someone is contacted, the less likely they are to respond. Microsoft helps make sure we all know who and who not to contact)
  • positively impacts my ability to focus, since you can mute notifications. Since I look at my computer all day, it is helpful to lock in and not get distracted by the many emails I receive a day. You can also change preferences, so emails with high urgency are still seen.
