Mimecast
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.

Zscaler
Zscaler is suitable for all organisations as the internet traffic can be managed very well without any concern. All the devices can be available under a single umbrella, which is easier to manage. The application can be managed via a console, but installation can only be done with the help of a dedicated crew as it needs a one-time password.

Pros
Mimecast
  • 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.

  • Automatically block the malicious content and websites
  • Scans inbound and outbound network packets
  • Has a proxy server through which all the network calls pass through
  • We have customized Zscaler Internet Access to block websites like Netflix, Hotstar etc which can hinder producivity

Cons
Mimecast
  • 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.

  • Given all of the features Zscaler Internet Access bundles (firewall, CASB, URL filter, DLP, etc...) it makes the console somewhat cumbersome. Anyone planning to utilize Zscaler Internet Access should be prepared to invest time in training or seek out professional services.
  • In some cases, the app risk index ratings do not include enough criteria to effectively assess an applications risk exposure. Adding more criteria or allowing customers to add their own would be a welcomed feature.

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
Mimecast
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.

Zscaler
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.

Alternatives Considered
Mimecast
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.

Zscaler Intenet Access outperformed the competition due to its lightning-fast policy delivery and cross-compatibility. It is easy to track employee usage and block unnecessary websites, reducing company internet usage. Zscalar installed on every system increases cloud-based software bandwidth, decreasing user turnaround time and increasing efficiency.

Zscaler
  • We cancelled our lease line contract and our static IP contract from our ISP which is a key win for us.
  • We can make sure that our users are connecting to our share drive securely even if they are on the road which is also a key win.
  • The negative side with Zscaler is we cant choose our internet gateway IP address as its managed by Zscaler.
  • Another negative side is Zscaler is not a complete package for us as we maintain our on-premise firewall (Fortinet) along with Zscaler.
