Cisco Email Security (ESA) Benefits

Information Security Analyst at a healthcare company
One of the things that I like most is that, since we do have a Cisco Enterprise agreement - we have a lot of Cisco products - we're able to consolidate reporting a lot better. Reportability is a lot more end-user accessible, or easier to acquire. The solution overall does what it does, but being able to quantify that, put it into reports that are easy to analyze, is probably the best and the largest gain that we acquired in switching.

Regional ICT Security Officer EMEA at a energy/utilities company with 10,001+ employees
When we first had Cisco hardware, we were having significant problems in that we were getting something like 10,000 emails per device per hour. We have four devices, so if we calculate that up it was like 1,000,000 emails a day, and most of those, about 99 percent, were junk mail or spam. We had a major problem with email, and introducing Cisco ESA systems was a set change for us. It reduced the number of unwanted emails by a huge factor. That has continued to be the case, from when we first got the devices, until today. Previously, we had other email security appliances, and they were overwhelmed by the volume of email that we are receiving as a company. The introduction of the ESA systems had two effects for us: * They significantly reduced the number of emails that were even considered for delivery or for being accepted into our company for internal routing. * It gave us another line of defense. We use the ESA systems as our first line of defense which we then follow up by another manufacturer's email security appliance, which gives us a second level. Subsequent to that, we've adopted another layer of email security. So we now run three layers. View full review »

In regards to what we filter out, we don't have a lot of information. We have a small team who handles most of the software, including the email filtering and email security. The solution drops bad email, like the spam or emails with viruses. We are not currently doing further analysis to indicate what was really targeted, or determining if something else with generated, malicious or spam. The filtering is okay, and we don't have complaints from our customers or users, so we aren't doing any further steps. The email processing and event logging are very detailed and valuable. They are also helpful when we troubleshoot email issues and perform email analysis, even though the logs are not structured properly. View full review »

We used to get emails with viruses that would impact the business or we would get emails with malware. We were able to scan the email and clear it or block emails with viruses. That was the business justification. On a weekly basis, it was blocking about 2,000 or 2,500 emails. It protects you, it protects your network, it protects you from phishing emails and malicious content and the like. View full review »

From a security standpoint, IronPort really helped with the mail filtering and load balancing between the Exchange servers they had. IronPort enabled us to blockade domains that send these emails. IronPort gave us fantastic service. By the time I administered it, I was able to block some 25 or more domains. View full review »

It means less malicious email, fewer interruptions, and less risk. It actually circumvents malicious emails; rather than getting to the users, the users don't see them. End of story. There's a risk without it. The user might get the email and might click on the link. Once that happens, they are toast, as is the network. The number of malicious emails it blocks differs from one company to another. It depends on the volume of email they get. I would say on average, depending on how many users there are, it could block 1,000 emails a day. View full review »

We need to differentiate among users with specific boundaries. Some users have full access and some users only have limited access. That is what we are using it for. View full review »

Before we had ESA, so we had more spam emails. In fact, we had some other solutions in place, but there was more spam going to the Exchange Server when we compare between we didn't have ESA deployed and when we deployed it. We cannot say it's 100 percent, but we're covered for 90 to 95 percent of spam. No spam is going to the user right now. View full review »

It saves a lot of time wasting. For example, phishing attacks distract a user's attention, and forged emails waste a lot of time. A user can lose data. This solution helps protect user data. View full review »
