Alark Singh - PeerSpot reviewer
Visual traffic interface aids in network micro-segmentation while a streamlined update option enhances process efficiency
The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies. We can write rules that can be embedded into the IP table, making it easy to handle. Illumio enables us to see network flows, traffic sources, and destinations. The policy generation and enforcement capabilities are valuable, allowing for selective enforcement. Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.
ShanavasVK - PeerSpot reviewer
Helps maintain a consistent posture of internet security while getting rid of VPN and hovering into zero trust
There could be a better way for the tool to categorize the traffic. For example, the tool does exceptions and everything overall. If I want to give guest access or provide access to guest users or any other internet access and if it does not go through the SSL inspection because, in our company, we can't have the root certificate on a device that we don't manage, which can be called out as an exception or an exclusion, but that doesn't provide a proper reflection of the picture of what is happening in the environment. There are granularities bringing it down. The tool I used or still have is Zscaler Cloud Connector to protect the cloud environment, which can have a bit more user-friendly installation and setup, and it would help a lot. The deployment process of Zscaler Cloud Connector needs to be more user-friendly. Improvements are required in the exception category. For example, suppose I report on a monthly basis what the breaches and traffic violating the SSL inspection area are coming from. In that case, I may find that half of them may be coming through some guest network, meaning the tool doesn't differentiate between the guest or normal networks or the corporate networks. Having options to differentiate different networks would be ideal so that it can show a true picture of things to users, as half of the things in the tool are not in our control and are not of our concern.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would recommend Illumio to all sizes of companies."
"Customer support is excellent."
"The features that I have found most useful is the ability to centralize all the rules and then distribute them across various locations. However, I've encountered challenges related to tagging policies, which can be complex to devise. It's a matter that requires careful consideration and stakeholder involvement before implementing such policies."
"The tool helps with my company's security posture."
"The solution is easy to use."
"The flexibility of the solution is its most valuable feature."
"The dependency map is most valuable feature."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"The solution’s customer service is good."
"The initial setup was straightforward. The biggest thing for us was to build our own policies. The deployment itself was only a few hours."
"Zscalar Internet Access is for Internet security, like an Internet security gateway. I like how it runs seamlessly in the background with a single sign-on. The controls you can have on devices for Internet security are good, and it doesn't impact speed wherever you're connected. Overall, I think it's very good so far."
"The solution has reduced cyberattacks."
"The most valuable feature for me is the ability to see how my network and traffic looks with modules like analytics and insights."
"The users are at different locations, and Zscaler helps us to put the organization's central security controls on these roaming users."
"We like Zscaler's traffic filtering, web security, DLP, and IPS features. The real-time threat protection is excellent."
"Zscaler Internet Access has helped us reduce the time that we spend managing security policies by about four hours a week. We can use this time to focus on other things, especially the IT team."
 

Cons

"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"I have not had the chance to experiment deeply with it."
"It requires a low-level re-architecting of the product."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"The product’s agents don't work very well in OT environments."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades. This would be more helpful to streamline processes."
"The solution's pricing is on the higher side. It would be better if it could be lower."
"What could be improved in Zscaler Internet Access is its price. It could be cheaper."
"Zscaler does not provide dedicated IPs to each customer. Hence, they share a pool of IPs provided by Zscaler. There is a chance of blacklisting these IPs. I also do not like the multi-management portal."
"The deployment process of Zscaler Cloud Connector needs to be more user-friendly."
"Zscaler should provide adjacent services, which would be complementary to their current offering that could to be more pragmatic for a customer. For example, if you take Akamai, you get multiple sets of services, all depending on the customer and the strategy and the complexity and the problems. In some areas, they are more varied in terms of coverage."
"Zscaler Internet Access needs to integrate more ISPs. It is good to have more than three ISPs."
"The OS capabilities and WSL support could be improved."
"In terms of usage, here in the GCC, it's still growing a growing market, so the combination of DLP, data leak prevention, to a certain extent is fine. But what it requires is user-based access or role-based access. The solution needs to grow into that, which definitely takes time. There's not an easy way to integrate it, when you have a cloud-based solution."
 

Pricing and Cost Advice

"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."
"It is quite expensive. It does its job, but it is quite expensive for what we need."
"Roughly, we might spend $70,000 a month on the solution. We don't pay for anything beyond the standard licensing fee."
"The solution is a little bit expensive. On a scale of one to five, I would rate it as a three."
"If we need any extra features, the price will increase."
"Our monthly fee is around R3000."
"Because it's a cloud solution, we pay on a yearly basis. It is affordable and includes tech support and all features."
"The price of Zscaler Internet Access should improve, it is expensive."
"The pricing is fair based on its competitive market."
