This is absolutely strategic. I think this is something that we're very proud, that we're so happy that it's coming. I've been patient, if you may, to get that done. I'm so happy that is on beta. In fact, Sumedh gave to one of the large customers a demo – real live demo about what was that about a week ago. I was, myself, personally floored. I could not believe the degree of integration that we have done. So fundamentally, to answer your question more specifically, is that the passive scanning does a few things. First of all, on the discovery of your network discovery, the scanning technology that we have mastered is really not good for the Asset Inventory, just give you a kind of a discovery, you can see what's going on but you don't have much visibility. Conversely, the agent technology we have also mastered, give you full visibility of the assets, whatever – what they are, what's on this asset, what has changed. The problem is that, of course, if you want to do your global IT Asset Inventory and you have, like most company, no clue about what you have, you get it with an agent. You have to know first. So, that's where the passive scanning comes in. The passive scanning listened now to the traffic and we detect any devices that connects. We have done a huge effort at fingerprinting large area of devices. We're adding also on the top of that the itime (41:32) capabilities. So now, certainly, we can identify those assets that comes in with great precision, thanks to the passive scanning. And now the question becomes do you want to have that device being managed, yes or no? Should that device have an agent or should we use authenticated scan or whatever other techniques, and then, of course, we continuously monitor that and I'll synchronize. In order to do that, that's a very important point that I'm making, you need a back end, which is absolutely significant robust today, not only an elastic search which, of course, allows you to essentially categorize, identify all these assets pretty quickly because you cannot use an Oracle database to do that. It will take you forever. So today, we have index on our elastic search clusters, 250 billion data points. We could do twice as much. Also, you want to have all that information that we collect also coming from different sources communicating very well. So on our Kafka back end now, we have scaled that back end to 9 billion events a day, I mean, significant. So, we have the muscle, the engineering, everything behind. Now, to finish the passive scanning also, we have a lot of other interesting use case as with our IOCs, like suddenly, we could identify not only just compromised device but suspicious devices and we'll eliminate the suspicion by listening to what's coming in and out of that device that we are deemed suspicious because we have classified all these – the matter where in two families, instead of just looking for precise hash or match, we can now look for what we call a family match. Other a very significant usage of the passive scanning is on the IoT. Because again, the IoT devices, it's very difficult to put an agent, although Qualys is coming with an SDK, so IoT vendors are going to be capable of building their own agent. But then, you also want to listen to the device because it's et cetera. So then, it's all about fingerprinting all these devices, which we're doing. We have a big team in India now doing nothing but fingerprinting. We are fingerprinting all the devices, as we speak, of a large manufacturer car company in Europe. So if you prefer that passive scanning is also a foundation for our forthcoming IoT solution, we have the backend, we have the platform, so we need of course a detection, and the passive scanning is very strategic for that. So, this is significant and that the scale at which we do, and no competitors of ours had that totally integrated in the platform. So, some competitors have the passive scanning since quite a while, but it's another application. It's not at all integrated with a platform. And that integration is not a walk in the park, I can tell you, because of the scale at which you need to really apply that technology.
