Cisco Secure Email Primary Use Case
It is used as the primary perimeter gateway for our organization before you can access our environment. Being hosted with Cisco, it goes through Cisco Secure Email Cloud Gateway. Spam, marketing, malicious or virus-enabled emails are not delivered to us 90 to 91 percent of the time because they are stopped external to the organization. That is a massive win for us. We don't have to worry about having to deal with all those emails going through our email servers.

The big use case is filtering inbound messages for spam and malicious messages. Obviously, it's a huge issue for everyone to keep as much of that stuff out as possible.View full review »
It is like a gateway for email. They receive all your email traffic. They send over your email traffic, and it is the first incoming point and the last outgoing point. They deliver the traffic to the destination. Whatever it is, you want to be informed of what is happening. Depending on the site's deployment, if you have a single device, then you have all the information on the device. And if you have several devices, you have all the information on every single device for each device. However, for consolidation, you need another device called Security Management Appliance (SMA).
It has no real interaction with other stuff. It does not interact with a gateway beyond the networking level. You have a router and that router provides IP addresses for a switch, etc. You don't have to integrate Cisco Secure Email with something specific since it is standalone and only requires basic essential networking. You can integrate it with a firewall, like ASA, but that firewall has to allow traffic. To do that, you would open port 25.
It is available to be deployed as on-premises, on the cloud, and hybrid cloud.View full review »
All of our inbound and outbound emails flow through the CES environment and we leverage it for spam filtering, phishing filtering, malicious URL detection, attachment scanning, and data leak protection. It basically covers all of the security layers for email.View full review »
It is our email gateway. We have the Exchange Servers, but the Exchange Servers don't relay directly with the internet. We have ESA in-between, and every incoming and outgoing email must pass through ESA before it gets to the internet.
We are using Email Security Appliance C690, and we have three of them in a cluster. They are on-premise. We have decided not to go to the cloud. It is primarily because most of our clients are government agencies and the government, and they have this suspicion about the cloud. So, right now, we are still on-premise.
Currently, we are on version 13.8. There is a newer version, but we are yet to migrate to that version.View full review »

We are using it for our email gateway security for all our inbound and outbound email. We use a lot of the URL filtering and spam filtering as well as the dictionaries, e.g., if they try to spoof employee names.View full review »
We are an internet service provider with a few hundred customers. All our customers need a reliable solution for email security and this solution from Cisco helps us to implement the customers' needs and to offer the security the customers want.
We are using all the appliances on premises. They are virtual appliances only. We are not using the cloud because we own our data center.View full review »

We migrated from Cisco ESA to Cisco CES, we went from the on-premise solution to the cloud solution.
Our primary use case is for email security. Every email is scanned by an antivirus engine and every attachment is also sandboxed before it gets back to the real person. This is an additional Cisco CES module.
On top of this module, we have also subscribed for the Cisco Cloud Secure Email Encryption Service (CRES).
Our other use cases are all about the functionality of the Cisco Email. We are using it as a relaying system for incoming and outcoming mail. External exposed webservices are using the Cisco CES in order to send mails out as our domains.
Another feature we use is the possibility to combine the Cisco CRES together with Cisco CES. All our documents are labelled and are obliged to be sent either through TLS (encrypted channel) or either through Cisco CRES (encrypted mail) for GDPR-compliancy. If the destination domain doesn't support TLS, it is sent by Cisco CRES, otherwise we use TLS. This conditional check isn't (yet) available at Microsoft.
We are using it as our email firewall. It's our first line of email defense.View full review »
