Room For Improvement

Illumio requires better support, integration, security, and flexibility, with improved upgrades, visibility, and interactive tech sessions for users.
The product can improve by having more multitenancy capability, which is currently not available.

I think they're doing a good job with DNS and as support for any domains that I create or that my clients create, it's mandatory for me to ensure they have Cloudflare as their DNS provider.
Owner at Hga consulting
And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network.
CTO at PlayNirvana
If the GUI includes notifications and improved logging capabilities that allow us to see traffic and store logs for six months, that would be very helpful.

Fine-tuning is a room for improvement in Fortinet FortiWeb.

Another improvement might be around scalability, ensuring that as organizations grow, Illumio can handle even larger, more complex environments seamlessly.

Most security products charge less at the time of purchase because of competition, but when we go to renewals, the prices become very high.

CTO at PlayNirvana
Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.

Have created granular security policies based on roles and application behavior
The best feature that Illumio offers is that we can easily understand how to label the applications, how to install Illumio agent on the client machines, how to install the agent on the servers, and how to do the ring-fencing. The log analysis is very simple, and we can map the traffic very easily, such as the traffic view and map view. We have many views to do that, and then we have a topology environment where we can expand the topology and understand how we want to prepare our policy based on the requirement. These are some of the very good use cases that Illumio provides, which none of the other vendors can offer in such an easy and usable way. The most important feature is the traffic review analysis, where we use the draft view and the reported view that helps us understand how the application interacts with other applications in the environment, and based on that, we are able to define the policies. It has increased the business for the organization. We are creating business by supporting the client. The client is getting more security and is more confident in their network because they now have the micro-segmentation feature in their environment. This is new technology and that's how it helps the organization as a whole. The clients we support are benefited, and at the same time, we are making money out of it. This is definitely a good approach. After implementing Illumio, there has been significant progress. Most of the app owners now understand what applications are communicating, how these applications interact with others, and we are more aware of which application is talking to what other servers and applications, and their roles. For instance, whether an application is talking to the DB server or an app server. We have a more granular understanding of the traffic view. Additionally, after implementing Illumio, there is greater segmentation, and fewer incidents are occurring. There have been times when an attack was halted from expanding laterally.
