Likelihood to Recommend Well suited: Proofpoint does a pretty good job at protecting us from spam emails. I was able to block a lot of emails coming from SendGrid by blocking SendGrid emails with a custom spam filter. However, SendGrid has a lot of legit emails too so I was able to create another rule to allow those emails from certain people, then block the rest. That way business need was met but spam emails are blocked. Less Appropriate If you are trying to monitor internal to internal emails Proofpoint is probably a little over featured for that.
Read full review 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.
Read full review Pros Spam - catches these emails before hitting the inbox. Daily digest - provides users with a list of the emails that were blocked and allows them to choose to release them if they are legitimate emails. Ensures that emails coming into our organization is safe for our users and verifies the email is coming from stated senders email server. Read full review 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. Read full review Cons Proofpoint could offer more frequent training opportunities to customers at all levels of expertise. Proofpoint can always continue to strive to keep its product a leader in the industry. Proofpoint's support site could be overhauled to provide a more logical flow. Read full review 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. Read full review Usability Very robust and solid product in protecting our emails. The engineers who assisted with our implementation was very knowledgable and great to work with. Easy to use by end-users. Administration and management are also easy for IT. Great dashboard and reporting tools for business reviews.
Read full review 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.

Read full review Performance Most important thing is the performance of processing mails. Even in a complex environment the system keeps performing on a very high Level.
Read full review Support Rating We use ProofPoint support quite often to fix issues and assist with setting up features and rules. Each time we have created a ticket, they have been very helpful and respectful. Each ticket has been treated with the appropriate SLA time and attention. We also enjoy the regular check-ins from the engineers when tickets are open but we get busy with other tasks.
Read full review 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.
Read full review Alternatives Considered We previously used halon anti-spam, which lasted us well until our organization really started to grow and it was not able to keep up with the amount of mail we were receiving. The support is also nothing compared to Proofpoint's professional services offering. Halon was also not able to have the complex rules that Proofpoint can offer.
Read full review 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).
Read full review Scalability You can add a lot of agents to your environment if you need them. And you can operate hardware appliances and virtual appliances in the same cluster.
Read full review Return on Investment Having easy-to-reach backups of all employee emails has made Proofpoint worth it by itself. That plus the countless times that spam/malicious emails did not make it through to the intended person that could have potentially cost the organization a lot of money. Read full review 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. Read full review ScreenShots
