Zscaler Internet Access cuts costs by removing legacy systems and reducing security, hardware, and management expenses, enhancing efficiency.
Cisco is a big brand in the networking domain, but in security, they are pushing a lot and improving day by day.
From my point of view, the biggest return on investment when using the solution is that it makes it a lot easier to delegate some of the tasks that were traditionally used, such as building policies on the firewalls and doing it through Cisco Umbrella.
The biggest return on investment when using Cisco Umbrella for me is the ease of use of the fact that we've deployed this with our Cisco VPN Secure Client, so every computer has the Umbrella module in it.
The biggest return on investment so far has been visibility, knowing what we have in our environment.
As a small team, Microsoft Defender for Cloud Apps allowed us to manage systems with just one or two people.
We have at least saved the costs we had from the Netskope solution this year.
The managed service aspect of Zscaler Internet Access has allowed for reduced staffing costs, resulting in a saving of approximately 20-25% compared to prior expenses.

I would rate customer support ten out of ten due to the excellent assistance throughout the POC process.
Cisco's support is fantastic, providing assistance when needed, especially during the initial installation process.
If I don't need to go to support all the time, that means the product is working fine, so I'm very happy with them.
Their customer service is pretty good, but it's frustrating to go through three or four channels before reaching the right person.
The support is excellent, and the speed of response is commendable.
There were instances where the engineers were knowledgeable and helpful, but at other times it felt like a ping pong game, with unnecessary transfers until the right person was found.
The technical support for Zscaler Internet Access is rated around seven out of ten due to some response time issues and the engagement model.
I find customer support to be quite adequate

Room For Improvement

Users seek improved integrations, security features, customization, licensing flexibility, interface ease, support, pricing, and deployment for Cisco Umbrella.
Microsoft Defender for Cloud Apps could improve integration, pricing, support, reporting, automation, alerts, and overall user experience across multi-cloud environments.
Zscaler Internet Access needs better integration, improved interfaces, pricing, performance, more data centers, and enhanced government site reliability.
Making it more flexible and easy to deploy, particularly when integrating with other technologies like Active Directory and proxies, would be beneficial.
The product can only shield a small area, making it less effective for larger spaces or multiple users.
I have to write an email to Umbrella support to get assistance, unlike the other products where I can call the Cisco technical assistance center and get an engineer.
For data loss prevention, it would be useful to be able to drill down into the kind of data being transferred over CloudApp.
Defender typically connects to Entra ID, but we have local users on the cloud for database access, SSH, or RDS, and there is nothing produced by Defender regarding those local IAM users.
A significant improvement I would like to see is the integration into a single pane of glass.
The response time and engagement model for technical support could be improved to handle complex outages more efficiently.
In future updates, I would like to see some of the features bundled into the existing product set, perhaps more AI features and a refreshed interface.
Zscaler Internet Access has introduced AI control for tools such as ChatGPT, providing options to restrict to text-only input without file or image uploads through CASB restriction controls.
 

Setup Cost

Cisco Umbrella pricing is flexible yet debated, with negotiable discounts and enterprise bundles but mixed views on cost transparency.
Microsoft Defender for Cloud Apps is cost-effective within Microsoft 365 bundles, especially for large organizations with discounts available.
Zscaler Internet Access is costly but valued for its robust security features, global coverage, and comprehensive capabilities.
We've bundled that with our firewall stuff and our VPN, which brings the price down and adds the ability to grow.
The only cost associated is the license cost unless additional solutions need to be integrated with Umbrella, which would incur extra costs.
The prices need to be lower as the current pricing is exceedingly high.
The pricing for Microsoft Defender for Cloud Apps is acceptable.
My organization is currently revisiting pricing, but previously, the cost was a bit expensive, yet comparable to other solutions with similar functionalities and features.
It's not the cheapest, but also not the most expensive, placing it in the mid-level range.
Zscaler Internet Access is recognized as an expensive solution.
Zscaler Internet Access is less expensive than competitors like Palo Alto, offering a premium service justified by security enhancements and cost-effective scalability.

Featured Reviews

Emilio Montoya - PeerSpot reviewer
Ensures internet navigation safety and boosts productivity
The features of Cisco Umbrella I prefer most are DNS protection and traffic redirect. With Cisco Talos's threat intelligence, we reduce the impact of malware traffic in our network, and we currently see the behavior of equipment and choose the correct sites. Cisco Talos has helped us reduce the impact of malware traffic. We can see the behavior and choose the correct sites. We're currently testing secure access with Umbrella in order to secure access to core applications. It's a product that the user doesn't even know is there, even though it is protecting them. It's not hard on the equipment. And, for us, it centralizes everything, which improves productivity. With the Experience Insights feature of Cisco Secure Access, we've seen impacts on the management of user connectivity by allowing us to deliver safe connectivity. We are testing the Secure Access product with Cisco Umbrella to improve our connectivity with our users in order to secure access to the corporate applications. Cisco Umbrella is in the cloud, which is nice.
Abdulrahman Muhammadi - PeerSpot reviewer
Integration with existing cloud workflows has simplified compliance and threat detection
Licensing cost is a significant concern. With Defender Plan 1, Microsoft Defender for Cloud Apps comes with a pay-per-use model. Each feature has its own pricing when activated on VMs. For example, the vulnerability assessment has separate pricing, the base model including encryptions has separate pricing, and the compliance features have separate pricing. This applies to each VM and Azure resource individually. It is not straightforward where you can take one license and apply it to everything. Each feature has its own pricing model which can be tedious, as the costs keep accumulating. The only lacking feature currently is XDR (extended detection and response). Apart from that, I have only positive experiences with the whole Microsoft suite, except for the pricing structure.
Mohan Janarthanan - PeerSpot reviewer
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.
