Cisco Email Security (ESA) Valuable Features

Information Security Analyst at a healthcare company
One of the nicest things is that parts of it are highly intuitive. For instance, black-listing, white-listing, and things of that nature are very easy to do and they're very intuitive. You wouldn't even need any training to be able to perform those actions straight out-of-the-box. Even though it's not perfect, it has the IMS engine, Intelligent Multi-Scan engine, and it does a good job, right out-of-the-box, of blocking the vast majority of things that should be blocked. Again, it's not 100 percent, but out-of-the-box I didn't have to touch it, I didn't have to tune it, I didn't have to tweak it. I believe it leverages the threat-intelligence database and does what it needs to do in making sure that the bad stuff stays out and virtually all of the good stuff makes it through.

Initially, the most valuable feature for us was the SenderBase Reputation, because that reduced the number of emails that were even considered by the system by a huge number, before we ended up processing them to get through the spam, the marketing, and the virus-attached emails. Since then, customized filtering has been very effective and useful for us. In addition, Cisco has developed the product with its Talos product. They've developed the ESA systems so that instead of just specifically stopping known spam sources and using that to stop virus-infected emails, the Talos solution which they're now providing has a lot of attraction because it helps to prevent phishing emails. Things such as Sender Domain Reputation, which is a relatively new feature, are attractive because when there's a pop-up domain, which might be a look-alike of your own company domain, or it might be a look-alike for some other company like Microsoft, it gets a bad reputation, and the ESA systems will reduce the possibility of these emails delivering to the recipient's desktop.

We like the in-built features, like the email filtering based on the IP and domain. Cisco has its own blacklisted domains and IPs, which is very good. This filters around 70 percent of emails from spam, and we are seeing fewer false positives with this. The notifications about why the emails were blocked is a good feature. View full review »

The most valuable feature was the anti-spam feature. You could set rules to block emails based on specific words like "pornography," "sex," "guns," "violence." That was one thing I liked about it. With the anti-spam, we didn't get all those emails. Also, Cisco was scanning our emails with their own intelligence. I liked that. Finally, the user interface was quite friendly, it was quite easy to use, unlike some other Cisco products. Anybody could use it. You don't have to be familiar with IT to be able to handle navigating it. View full review »

One of the most valuable features would be the logs. There were detailed logs available. That was a seriously good feature. There were cases in which some spam mails penetrated through ESA; users reported that these were spam. The support was also good from Cisco. I got in touch with support and they helped us. It turns out these were actually spoof emails that came into our environment. I got to know about them from the log system. I was able to create a filter as a result. For me, the ease of use was good. From the logs, from the configuration, from the monitoring perspectives, it was all good. View full review »

The filtering is something I found very valuable. Also, the users were able to do a check by themselves on quarantined emails. They could check if a valid email had been stopped, if it matched up with the SPF certification. The kind of environment we ran was a kind of complex environment. For us to be in compliance with PCI DSS and ISO 27001, the users needed to implement this and we needed to know how often we got unsolicited emails and how to mitigate users being victims of spear-phishing or phishing attacks.

The most valuable features are protection against ransomware and spam. Those are the main two features. It also adds an additional layer to your networks. Cybersecurity isn't a comprehensive solution. You have to keep on adding layers without disrupting the flow of the business. The Cisco Email Security appliance does that, where it adds another layer without slowing down the business or the performance of the network. View full review »

The most valuable feature is the policies or rules that you can put on it. This definitely helps with routing specific things to different destinations within our organization, or even potentially blocking when something is coming in and out, to where you can't do this on an email server or on our other email gateway. It's just not possible. View full review »

We are using almost all the features because they are necessary to protect emails. The most valuable feature is the different content filters we are using, such as DKIM. The Anti-Spam feature is also valuable for us because, most of the time, we notice that what is coming in is spam, and the Anti-Spam filter works very well. That's one of the features we like most.

after doing a third party pentesting, they found the security at a high level regarding the messaging security part testing,and the only recommendation they gave and need improvement is adding the sendboxing, for those attack ranked at zero day attack, which can't be detected. knowing i'm using premium licensing, i checked the Advanced Malware Protection (AMP), which is on-demand feature, i found that, this feature act like a sendboxing View full review »
