Setup Cost

Cisco Web Security Appliance is costly, suitable for larger enterprises, and aligns with market trends for robust security features.

It offers the same features you would get from a vendor that charges 250,000 British pounds for a fraction of the price.
Head of Cybersecurity at SES Water
The following year, the cost of just licensing was similar to what was paid the previous year for a new appliance along with the implementation and licensing costs.

Cloud gateway has strengthened remote web security and now needs better Mac and ISP support
The problem our organization had is that iboss failed for the Mac devices. It is not able to give a successful agent for the Mac agents. That is where in 2025, we had to migrate to the Palo Alto-based platform. If your use case is for just Windows laptops,you can consider this platform as an option One issue is the data center resiliency part. In India especially, they are not tied up with the Tier 1 ISPs like Tata or Airtel; they were having Tier 2 ISPs and encountered many issues reaching few major sites that my organization depends on, and they were having problems that they could not fix quickly. They also lack a mechanism to route that traffic within their data center; rather, they ask customers to make a pac file change to route it to Singapore explicitly. It would be better if they route from their backend , i mean even if I send it to India DC, they should be able to route it internally to make that work; however, they fail to do that and ask the customer to route it in the pac file. Another suggestion is that in China, they do not have the proper setup; they used to have numerous problems with slowness and lack of premium circuits in China as well. That leads to multiple sites working slowly with latency-related issues. So the main issue is the ISP-related problems that need to be solved.

Advanced protection features offer robust security while integration process presents challenges
With the WebAssign integration, it is not easy when I am integrating policies within the company, especially with NAND and wireless policies. The challenge arises when traffic is blocked from either wireless or wired connections. Although implementing it as a standalone is quicker, integrating BYOD with Cisco I and FTB can be tiring. Once it is done correctly, the functionality and reports become valuable, although the implementation part can still be challenging.
Mohan Janarthanan - PeerSpot reviewer
Associate Vice President at Novac Technology Solutions
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.
