Zscaler Internet Access™ (ZIA) is a secure web gateway (SWG), delivering cloud native cyberthreat protection and zero trust access to the internet and SaaS apps.
For a larger organization, this is a must. It provides insight into what the users are doing online and most malicious sites will no longer be accessible if access is denied. This can also give access to non-work related sites, but in a limited capacity, based on user or time of day. Though a smaller company would benefit from the features, it may be cost prohibitive.
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.
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.
There are a lot of settings you can adjust. The web log is easy to use. If a user is having issues accessing a website, you can go in and see what's being blocked and why. After that, you can make adjustments fairly easy. The GUI is easy to navigate and updating the software is a simple click of a button.
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.
Barracuda support have also been excellent when we have had to contact them. The only time we had a hardware issue on a device (and that device was about 8 years old) it was replaced within about 24 hours of reporting it. Generally there has not been much need to contact their support, as once the device is in and set up, it just works.
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.
SonicWall, Barracuda NG Firewall, and WatchGuard provides Content Filtering, but are primarily firewalls with Content Filtering features. The Web Filter is a dedicated appliance with more storage space and better reporting of users.
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).
