Featured Reviews

Ken Bauer - PeerSpot reviewer
Senior Security Analyst at a retailer with 5,001-10,000 employees
Segmentation of legacy systems has protected outdated endpoints and reduces network risk
The best features Akamai Guardicore Segmentation offers make it simple to see all of the connections that are being made to each of the endpoints, and they can be controlled by process and port. The ability to control by process and port helps my team day-to-day because, since there are hundreds of thousands of connections to some of these endpoints, looking at the Reveal Map makes it simple to audit and create rules for what we want to allow. Akamai Guardicore Segmentation has impacted my organization positively because we find it difficult to remove the legacy systems, so it was very important to segment them from the rest of the network to protect them and protect the rest of our network.

Cyber Security Architect at a tech vendor with 10,001+ employees
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.

Has improved network visibility and security through micro-segmentation and SDN capabilities
This feature gives us flexibility and allows us to manage everything under one pane. We can see everything on one console, including network operations and behavior. Monitoring and security are among the best features for VMware NSX. For micro-segmentation, it's integrated with our endpoint security. If there are any issues with servers or VMs, it notifies us so we can isolate the servers and investigate. It provides distributed security features such as firewall and intrusion, IDS, IPS. The security level with IPS and IDS in VMware NSX is excellent. It also provides logical switching and routing which gives an extra layer for Layer 2 and Layer 3 switching requirements. The solution provides flexibility, automation, and self-service capabilities, resulting in cost savings as extensive expertise isn't required. Once automation and self-service are implemented, many tasks can be completed automatically. Load balancing is another excellent feature. Multiple servers can run on load balancing features, which is particularly useful since we have many application servers running. Sharing loads between servers provides the best performance.
