Email Secure Gateways

Soliciting input on ESG’s and do you use? If so, what vendor and why did you select them over the dozen or so options? Just curious to get your input as they all provide a filtering service and some offer awareness training. I know Mimecast, Ironscales, and proofpoint are highly rated. What about some of the others? SpamTitan, Barracuda, Microsoft? Would love to know your real world experience using the product you selected.


I looked at a few. Ended up going with Check Point Harmony Email & Collaboration Suite. We’ve used Mimecase, ProofPoint & EOP.

I really like ProofPoint, solid system. The hospital I work at is just to far invested in Check Point so we went this route at our renewal.

We use Mimecast for our clients, it works well but has a lot of options which can be a bit overwhelming.

I usually suggest Proofpoint to customers. I find it to be very good and their documentation is great.

Thank you for the input. I wonder why there is not much conversation around the MS Defender for Business since it is packaged in with Business Premium? User limitations or does the 3rd party ESG just perform better and have more features?

Thank You,
