Suffice to say, we are sending and exchanging E-mails that are sometimes encrypted on a regular basis; as a result, this product has provided great efficiency in protecting against hacking, intrusions, and phishing.

It has create chaos and then i am implementing Zerospam as a quick solution for this problem. Almost no spam email has ever reach my main inbox anymore since then.

Microsoft offers free spam filters but they didn't catch a recent ransomware (cross-tenant so they didn't went through zerospam), ZeroSpam did. It blocked every single one of them without any kind of manual configuration. True set and forget is rare these days, this is one solution you can put in place real fast and never think about again, it just works. Plus there's an easy to install outlook plugin to report spam if there's ever one going through. Pros only the features you need easy to install and manage great support cloud based Cons Absolutely none! I only had a good time with the product Reasons for choosing Zerospam better product for cheaper, it was a no brainer.

DevOps and Release Manager Computer Software ### "Zerospam Functionality and Support" 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 September 14, 2020 I ran a development team for five years, writing a competing product. I mention this only qualify my comments. Once we got out of that business, we chose zerospam to handle our mail. It has all the features you need, none of the fluff you don't. Pricing is well within reason, I would consider it a bargain considering the administration time saved. While the product itself is reason enough to write this review, the support team is "the cherry on top". Proactively checking the system, resolving \*barely any\* false positives before my users wake up, expertly answering complicated tech and edge-case scenario questions -- and equally important, should the answer not be evident, not wasting my time pretending to know, but escalating in a timely fashion. This not only saves me time, but gives me time back. Pros Zerospam catches 'all the things' that shouldn't get into the mail system and lets 'the good stuff' get in. While it offers a user interface, I can't say I ever got a chance to get to know it as the performance is so good I never actually have to tweak anything. Cons The user interface is a tad dated, but that's barely relevant.

It works right out of the box with a bit of setup and tweaking, my email was spam free within a few hours. Once set up correctly, it works in the background with very little effort or attention needed by me. Cons It's expensive, but I think if your serious about reducing the threat of phishing emails or dangerous email viruses, this may be worth the money.

Owner Information Technology and Services ### "Great product. Needs little support, but when it is required, the support is excellent." 5.0 Overall Rating 5.0 5.0 Ease of Use 5.0 5.0 Features 5.0 5.0 Customer Service 5.0 5.0 Likelihood to Recommend 10/10 December 30, 2019 Great! Pros I moved all of my client's email from a server based anti-spam solution to Zerospam, which is cloud based. I no longer have to worry about server crashes, power failures or dropped Internet connections. Set up is easy and ZeroSpam support walked me through the first couple of domains I on-boarded. False positives are rare, while very little actual spam gets through. Pricing for domains using Exchange Online is very competitive. That, coupled with the quality of the product and support, makes ZeroSpam a great value! Cons Only a couple of cons, but nothing that out weighs the pros. One, I would like to see the logs update to the current time when clicking Refresh. To update to the most current 24 hour period (even a minute later), you have to leave the logs and come back into them. Two, the use of the names ZeroSpam and Cumulus can be confusing at first. ZeroSpam is the filtering product and Cumulus is the web interface. Though, maybe not possible, if there were any way to only use one name or the other, I think that would help. Alternatives considered [MimeCast Email Security](https://www.capterra.com/p/119826/MimeCast-Email-Security/) Reasons for choosing Zerospam Price, based on what I was looking for. After the fact, I found out that ZeroSpam's support is excellent. Review source Non-incentivized review: any software user can leave a review for any product listed on our site.

Response from Vendor September 21, 2020 Thanks Walt, it is highly appreciated you review when all you need is a hands-off operation, peace of mind for your business, on a highly secured cloud based service environment and finally no interruptions to service is key for business continuity.
