Cisco Email Security Scalability

We haven't had to address scalability. The umbrella IronPort is broken down into two halves: email security and web security. I haven't had to deal with the scalability of the email security at all. But since they're both under IronPort, I have had to deal with scalability on the web security end. Relying on some of that experience, my assumption is that the way it worked for the Web Security Appliances is probably pretty similar to how it works for the Email Security Appliances. With that in mind, I can say that scalability is not an issue. It's as easy as just bringing another ESA into the cluster. In terms of plans to increase usage, if you ask any enterprise they're going to tell you, "Yes, of course, we're going to grow, and as we grow we're going to use more." And the reality is, any growing enterprise is going to utilize email more and more. As the landscape morphs and changes, so do your rule sets and the features available to you on these appliances. Will we be using it more and more? Absolutely. Will it be a daily thing? Absolutely. I'm in these appliances every single day, taking a look and tuning where necessary and trying to find more efficient ways to handle the email traffic flow. It's safe to say that for any enterprise that's going to be the case. View full review »

The scalability is good because when you have appliances such as we have, if you have the infrastructure and the available resources, you can install additional virtual appliances. From the point of view of scalability, if there were a problem with performance, it is possible to add other systems or devices, even though they are virtual, and they all fall under the same control interface. They are all a part of the same cluster so they are all relatively easy to manage. We currently have 11,000 employees and a large number of those users hold email accounts and email addresses. We have a 24-hour operation because our company is located in 62 countries, so we have to respond relatively quickly because email is important. We have a department that deals with IT security and likely, at a minimum, we would have six people who have the capability to work on these systems. But in reality, because the systems are very stable, we have three or four people who regularly work on them. All the people who maintain the system are currently in the same department as me and all of them are considered IT security officers. They deal with other systems as well as the email.

It's very scalable. It can grow much larger than I probably would utilize, but I don't like to put all my data in one box. the scalability is enormous in the PowerMax. View full review »

Information Security Administrator at a tech vendor
We added one appliance to the platform and upgraded one to a newer version. The company did it quite easily. I was not part of that implementation, but the another guy told me that it was quite easy to do. There were no plans to increase usage of it in that company at the time I was there. It was used by about 800 users and, since all of the users were using it and the organization was limited, everybody was already onboard. We had licenses for all of the users. It was all well designed from before. Apparently, they had to procure licenses for 200 to 300 more people, but that was after I left the organization. I didn't see what happened at that point.

Network Security Engineer at Konga Online Shopping Ltd
It's scalable. In the enterprise in which I had to deploy it, there were between 500 and 1,000 users, so the scalability is quite okay. We had two ESA boxes and there was load balancing using Cisco ACE. The scalability is okay. There weren't any plans to increase usage, as far as I can remember. It was used very well and they're still using it. I do interact with the current engineer now, and I don't think there has been a serious issue of late. The only issue he told me about is some outside mail is being trapped by the current site. View full review »

It's very scalable, especially the cloud version. You can get up to about 100,000 users on the appliance but the cloud version is more flexible. When you do scale it up you don't see slower performance. In the largest environment in which we've implemented it, there are 200-plus users. It's utilized by 100 percent of the users. It's not at 100 percent capacity. View full review »

Scalability is good. We have four appliances total clustered, two in one data center and two in the other. The ability to increase is definitely doable, and it's helpful if you need to do that. We are a legal firm with close to 2000 employees. View full review »

Network Security Consultant at a tech services company with 51-200 employees
It's scalable. A medium-sized business would go with a C370 while a small business would use a C190. We are able to migrate users from lower-level to higher-level products. Scalability is not a big issue for this product. The same configuration can run 500 users and 3,000 users. View full review »

Group Head of Cyber Security at a transportation company with 10,001+ employees
Scalability is very good. We have not faced any hiccups over the years with a 15 percent increase per year in the number of users. We currently have 3,000-plus users in our organization. It is one of the main security controls we have and is used extensively. We don't have any plans at the moment to increase usage, but that might change. View full review »

Everything is fine with the scalability. We have 400 users on this product, with two site, 2 physical appliance in one site and one physical appliance in the second site the three working as a cluster, and next year, we plan to increase our usage and move to the newer physical appliance version. because those we're using , are arriving to them end of life soon.
