What is our primary use case?
Our primary use case for this solution is to monitor east, west, north, and south traffic so that we can see what's going on in the network internally. You don't get that granularity with anything else. We have an ASA that gets north and south traffic. So we're just really interested in this one by itself.
How has it helped my organization?
Cisco Stealthwatch has improved our organization's analytics and threat protection capabilities by catching threats early on. We are still at the baselining stage, but I can also say that our organization improved dramatically when we found out that a host was constantly talking to an FTP server. It turned out to be an employee that was going to be terminated and he was trying to pull data from the FTP server constantly. He pulled three or four GBs and we caught it with this tool. It saved us a net fortune.
The solution has also increased our threat detection rate dramatically and that gives us time to remediate those threats.
What is most valuable?
The most valuable feature of this solution is data hoarding because it catches threats on a frequent basis that we had no idea of. Like if certain hosts were talking to certain hosts. With this tool, we got that kind of information and it allows us to see when two hosts are talking when they shouldn't be talking at all.
What needs improvement?
One thing I would like to see improved is if it could automatically be tied through ISE, instead of you having to manually get notifications and disable it yourself. I am the only network admin at my facility, and when I'm on vacation for a week and there is an attack, I'm the only individual that gets alerts. Essentially there's a push button that you click to implement the policy through ISE to block that host or some other network essentially segregated from your internal network. I would like to see an automatic block function.
I haven't noticed any downfall as far as CPU usage or any congestion, but it is still too early to say. Once I get a better understanding of it and get past the baselining, I can probably answer better and in more depth, because I don't know everything about it. I just understand the fundamental idea of it and what I can do from the dashboard.
What do I think about the stability of the solution?
It is extremely stable. I haven't had a crash since installing it.
What do I think about the scalability of the solution?
It is very scalable. You only have to purchase more licensing. As far as I understand, it can become as big as you want it to become and how many net flows you can afford.
How are customer service and technical support?
The technical support is awesome. Anytime I call Cisco Tech, they call me back within thirty minutes or an hour with an answer to solve the problem. The guides that they have within the product itself are pretty self-explanatory. As long as you're willing to sit down and read it, you don't even need to call tech.
If you previously used a different solution, which one did you use and why did you switch?
My superior asked what this host was doing within our network, what data he was pulling and why he had it on this PC. We couldn't answer to say that he wasn't pulling data from that server or what data he was in fact pulling. So we had to find a solution to answer those questions. We are a Cisco shop so we kind of just went for this solution.
How was the initial setup?
The initial setup was straightforward. They explained the steps that they were going to do and they had it deployed within about two hours. It didn't take long and now we're just doing the baseline, which takes about three months.
What about the implementation team?
Yes, we used Network Center and they were good.
What was our ROI?
I can foresee that this solution will save us an immense lot of work in the future. Instead of having 20 people looking at logs and sifting through logs, you could have one individual simply sifting through this. It will be a lot easier and less time-consuming.
So the time to value of this solution is great. For every person you're going to pay about $70 or $80,000 a year, you would now only have to pay one individual instead of 20.
What's my experience with pricing, setup cost, and licensing?
This solution is a little expensive. Open-source is obviously a key to victory in some people's eyes but with open-source, you can't pay anybody. So it could be a little cheaper, but it has great functionality.
What other advice do I have?
One thing I've learned from this solution is that there's a lot of stuff happening within internal networks that we weren't aware of. I am really satisfied with this solution and I will rate it a ten out of ten.
