A review from an organisation with both on-prem and remote workforce.
- 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
- My personal opinion about Zscaler is their idea is that all the services are online and are moving to the cloud but the truth is some of them have to stay on-premise and employees still need to work from an office. Zscaler simply doesn't have any on-premise solutions like an NGFW to provide a complete package. We are supporting Fortinet NGFW for our on-premise solution.
- As mentioned earlier Zscaler being hosted online we don't get the full flexibility of managing our firewalls. Although it's a good thing we keep running into problems like when we want to allow list a service from a specific source IP Zscaler cannot provide a static IP for that. They route traffic through multiple IP addresses and the IP's keep changing every 15-20 minutes. So you cannot allow list a specific IP on the receiving end. The only way to move forward would be to allow an entire range of IP's which opens a security loophole on the receiving end.
- For every small thing we have to keep opening a ticket with Zscaler. Their response rate is fast but still in a fast-moving world it's not fast enough. Especially since we need to get approval from our change control to get something done and then again we have to raise a ticket to get something done from the Zscaler side.
