Cisco ASA Firewall Primary Use Case

JF
Cisco Security Specialist at a tech services company with 10,001+ employees

The ASAs are a defense solution for companies. Many of them use the AnyConnect or the VPN licenses. They also use it to have a next-generation firewall and to be compliant with GDPR.

The majority of our usage of the solution is on-prem or hybrid. The culture, here in Portugal — even knowing that the future is full cloud, in my opinion — is to only be on the way to full cloud.

The first time I deployed Cisco ASA was for one of our clients. This client had a Palo Alto firewall and he wanted to migrate. He bought an ASA 2505, and he wanted us to come in and deploy it and, after that, to put in high-availability. We deployed it and the high-availability means that in case one fails, there is a second one to take over.

I have deployed Cisco ISE and, in the same environment, we had a Cisco FTD. In that environment, we were using the ASA for VPN, and we were using the FTD like an edge device. The ASA was deployed as VPN facilitator and for the wireless part too, so that the wireless network was under the ASA firewall.

We use the Cisco firewall for a number of things. We've got VPN tunnels, IPsec tunnels. We also use it for basic network layer filtering for our internal service, because we have a number of services that we offer out to clients, so that is the first device that they come across when they get into the network.

We have a network of six remote sites and we use proxy to go to the internet, and from the internet Cisco is the first line of defense. We have internet banking services that we offer to our clients, and that also makes use of the Cisco firewall as the first line of defense. And we've got a number of servers, a Hyper-V virtual environment, and we've got a disaster recovery site.

We had VAPT (vulnerability assessment and pen testing) done by external people to see our level of security from inside and outside and they managed to find some deficiencies inside. That's when they recommended that we should put in network access control. By integrating the ASA with Cisco ISE, that is what we are trying to achieve.

The whole idea is to make sure that any machines that are not on our domain should not be able to connect to the network. They should be blocked.

We also have Cisco switches deployed in our environment. All our active switches are Cisco. The ASA is integrated with them. This integration was done by a combination of our Cisco partner and in-house, because we did this at the time of setting up the infrastructure in 2016.

We primarily use it for our clients. We have one or more at each client site - or multiple locations if they have multiple locations.

Typically our clients are up to about 500 users. Most of them are smaller than that, but they go as large as 500. They're using the solution for the full next-gen firewall stacks - intrusion protection, URL filtering, advanced malware protection, or so-called AMP. Those are the three subscription services that Cisco sells. All of our clients have those subscription services enabled at their main location. Typically, they're just protecting users that are behind the firewall. We also use it for site-to-site VPN, and we use it for client-to-site VPN.

We are a Cisco partner and we implement solutions for our customers who are generally in the banking sector and other private sectors.

They are using it as a data center firewall and to secure their internet connections. Our customers usually integrate the firewall with ISE, with a Firepower module for IPS, and there are some NAC solutions.

We were using ASA 5585 without firepower. We were using it just as a stateful firewall. We also had an IPS module on it. So, we were also using it for network segmentation and network address translations for hosting some of the services or giving access to the internet for our end users.

We primarily use the solution to operate that LAN environment over the internet and use the public and private networks separately. It's a very good firewall in terms of security, in terms of certain scenarios, and also from an ethical hacking point of view. Both are available in our environment. Both are doing great.

Cyber Security Consultant at a tech services company with 51-200 employees

Most of our use cases revolve around the basic firewall features. Our client is also leveraging on Anyconnect, which is serving the client-based VPN. Sometimes they will establish a VPN connection from one firewall with another. It's the type-for-type VPN. In terms of Cisco, typically, these are just some of the legacy features, that's what we use. In terms of a next-gen firewall, I feel that our customers would prefer to use other brands like Palo Alto, Check Point, and FortiGate.

Our clients who use this solution are typically small businesses. I think there's a Gartner chart that says that Palo Alto is actually the foreleader, followed by Check Point, then FortiGate. Cisco is not anywhere near. From a cybersecurity standpoint, they are quite weak.

Our business requirements are URL filtering and threat protection. We're using the Cisco 5525 and 5510 series. We have eight to 10 firewalls.

Our company is looking for vendors who can protect from the current, advanced technologies. We are looking for any technology that protects from the most threats, and that covers things like DDoS protection, spyware, and SSL.

Network Engineer at LEPL Smart Logic

I have used the Cisco ASA 5585-X Series hardware. The software was probably version 9. We implemented a cluster of two firewalls. In these firewalls, we had four virtual firewalls. One firewall was dedicated for Edge, near ISP, and one firewall was for the data center. One firewall was for the application dedicated to that company, and one firewall was dedicated only to that application.

Some are being used as edge firewalls and others are for our server-farm/data center. So some are being used as transparent firewalls and others are used as a break between the LAN and WAN.

In addition to the firewalls, we have Mimecast for email security as we're using Office 365. We're also using IBM's QRadar for SIEM. For antivirus we're just using Microsoft Windows Defender. We also have an internet proxy for content and for that we're using NetScaler.

One of the things that we have solved the most with this solution is the P2P connection that we have with different clients. It gives us greater connection security with good management of the configured rules. 

Likewise, it has made it easier for us to have this type of equipment under monitoring, and, since we have implemented them, we have not been presented with any performance problems in the equipment as they have not presented CPU or RAM saturation or that for some reason it fails without any cause. We all have them managed and monitored. We always receive an email notifying us if there's something that the equipment has detected as well.

Our primary use case is for perimeter security.

We are using the enterprise version. Cisco has many versions. Maybe we are using the old version of ASA because it needs to be the freeware. In each freeware, there are different types of things. Maybe it is the standard version because the other version cost a lot. I need to combine it with another solution like an open source standard solution of the ASA firewall from Cisco.
