Mimecast
Mimecast is good when you are needing a basic email security platform. It does some basic things really well, but when you start hitting some advanced needs, it lacks. Mimecast does not do a good job with BEC detection. Mimecast does spam filtering alright, but it could be much better. It really doesn't care about gmail or other external addresses. It doesn't check for age of accounts, etc.

Zscaler Internet Access is an internet tunnel that pairs with the network adapter to secure traffic between servers and workstations. It can refresh policies automatically and log intrusions but does not broadcast intrusions. Cloud-based Zscaler Internet Access is easy to deploy and scale, with no hardware or software needed. In a hybrid model, Zscaler Internet Access performs some security functions on-premises and others in the cloud, allowing organizations to keep infrastructure. There is a slight learning curve from VPN and appliance architecture to this paradigm.

Pros
Mimecast
  • Email retention - convenience for the end-users to access older messages even if they've deleted them from Outlook
  • SPAM management - allows us to prevent SPAM and Phishing attacks with custom policies that fit our organizational needs
  • URL protection - allows incoming emails with a URL to be scanned and protects our end-users from clicking on malicious URLs

  • Zscaler completely moved away from the traditional firewall setup to a hosted firewall solution. We don't have to worry about the hardware failing or maintaining it as part of our service plan compared to our on-premise firewall. Zscaler has a lot of data centres across the world where they are maintaining their solutions so mobile consultants will always be close to one of their data centres.
  • Rolling out Zscaler solutions to our end customers' computers is actually pretty easy and hassle-free. As part of onboarding of new employees we can set up the Zscaler solution and push it to our end users' machines and get them connected to the cloud solutions.
  • Zscaler does proper market research on the latest emerging threats and they keep their firewall patched and updated to the latest versions so the security team does not have to worry about keeping the firewall updated.

Cons
Mimecast
  • The Admin Management console is absurdly complicated. For every first time we wanted to setup we've had to call their support for assistance. Support is quick and fantastic but it's so difficult to do anything yourself. They seem to have gone out of their way to call features unique things instead of using standard language from other providers so you as an IT professional know what you're looking for to setup.
  • They have lots of KB articles, which their support will point you to. They are written on the most basic level and don't actually provide the help you need. For example, the KB page will tell you the list of options on the page... but not actually tell you what you do, why you might use them, or define their terminology.
  • Their email threat management system has several nice features. One of the features available is that it will rewrite links in emails so that users click the link and it sandboxes the link, testing it on their server space and the user sees it there. This means the actual link in the email gets changed to the address of one of their servers. As a law firm, the EXACT LINKS are important to maintain in our communications and editing actual data from our clients to point to a Mimecast server is an unacceptable practice. I wish they had an alternative that did not edit the link itself on the page.

  • Chat or email support is not available. Only option is to either call them or raise a ticket by logging into their website.
  • Pricing is not transparent and quote based.
  • Access to websites is a little too slow with Zscaler monitoring on.

Yes using the same administration console is good, as user that you have assigned limited functionality to the console, they are already familiar with it when you increase their functionality. The new portal does take a bit of getting used to, but i can see that it is an improvement on the old version.

Zscaler is a mandatory solution required by almost every large organization with a workforce working remotely or using cloud-based apps. Its deployment is relatively easy and it keeps on working in the background without actively bothering the user. Apart from a few weird messages which a user is unable to comprehend, Zscaler is able to provide fast and safe access to the internet and other external applications.

Support Rating
Mimecast
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.

I cannot give a fair rating for this as I have not had to contact Zscaler support. There was one time we had to contact them because we needed to check if they were having issues on their end. Our ISP was actually the problem but support seemed very friendly.

Previously we have only used the default on-premise exchange that comes with SBS. This was very simple and only provided basic filtering of spam and junk mail. We weren't able to filter impersonation mail or emails with malicious code

Zscaler Intenet Access proved to be superior and the difference for us was the speed of policy delivery since your policy is applied in a web console and is effective in a matter of seconds. Another point to congratulate the solution is its compatibility with different platforms (macOS, Linux, Windows, Android, and iOS).

Return on Investment
Mimecast
  • Reasonably priced solution, even for a small business like ours.
  • It's hard to put a figure on our ROI - I would just say we feel like we've gotten our money's worth with the advanced email protection we receive. We have definitely avoided many potentially dangerous emails since we've implemented this solution.

  • ROI is there and it is safeguarding the data and user access to net.
  • Being a cloud based can be scaled up when required.
  • Third parties can be allowed based on the company IT policies (Clients or Vendors etc.) for business perspective.
