Cloud features enhance security measures and simplify network management
I've dealt with many firewalls, such as SonicWalls, UniFi, pfSense, and Cisco. We found SonicWall very confusing for the average network engineer or network administrator. I don't recommend SonicWall due to its hard-to-find auditing process for exploits. Although they have fewer exploits, when they do occur, they're significant. With Fortinet FortiGate, you can access the whole firewall, with no hidden spots. pfSense is great, however, it requires a lot of manual work and has no Cloud Connect or easy management from an MSP's perspective. Palo Alto is another option that's great, but their price point isn't for everyone, especially for medium and small businesses; a $10,000 investment doesn't necessarily fit into most budgets. UniFi is another product we've started to use more alongside Fortinet FortiGate, as they have almost all features without a license, with advanced rules that are relatively inexpensive compared to Fortinet FortiGate's $1,500 a year. Fortinet FortiGate and UniFi are the two firewalls we primarily deal with. My opinion is that UniFi has better integration and oversight of the environments compared to Fortinet FortiGate.

Automated breach prevention has protected critical workloads and keeps external attacks blocked
I am familiar with SonicWall TZ. I have done a POC of TZ but I have not worked extensively with it. I have worked with the 2600 firewall and then the 3600. These are the models which we have worked with.SonicWall NSa was an on-premises solution. The two firewalls which were in production, in the data center and on the LAN side, were both on-premises solutions. We had a pre-decided budget under which we would purchase the firewall. All parameters including security, high availability, and budget concerns were covered with SonicWall NSa being implemented at that time. SonicWall NSa is a user-friendly product that is easy to configure, and it is easy for network personnel and firewall administrators to work with. Even the L1 team captured and learned this firewall effectively, helping us resolve all parameters related to high availability firewalls within budget-friendly costs. I rate this review a nine out of ten.

User access management and threat prevention are enhanced with user-friendly controls
The best features Zscaler Internet Access offers include application control, tenant segregation, and PoP center regions which have low availability zones. The internet access is very successful and bandwidth speed is excellent. It also has application-based control, URL-based control, and SSL inspection capabilities, which are very useful. Additionally, the in-depth CASB segregation is very beneficial to us. One unique feature I found helpful is the tenant level restrictions, which we use to only access our organization's tenant level mail IDs, drives, and specific tenant level access while restricting public access. Zscaler Internet Access has positively impacted our organization as we have noticed substantial outputs and income. It has improved our security environment control and endpoint protection. It prevents numerous web attacks through its AI/ML incorporated capability which identifies malware, threats, and viruses. It has a toggle button to enable features entirely at the tenant level for all users onboarded into Zscaler Internet Access, resulting in much better outcomes.
