The key improvement for us were: * The additional monitoring 24/7, and using the high fidelity alerting from Vectra rather than SIEM, This was our biggest change. We have managed to leverage that rather more than our SIEM, which just throws out loads of spam. * The FCA requirements to build on behavior monitoring. * The use case of the call center with its high turnaround of staff who are perhaps not as clued in or engaged in our user awareness program as they could be. * Lack of end user deployment is another big improvement. We wanted something that was easy to deploy, or get up and running really quickly. It took a couple of weeks to rid of the alerts that we didn't want, but the actual involvement from the network teams was minimal, which was really good for us because we just don't have the resource to spend a lot of time trying to configure devices. We use the solution’s Privileged Account Analytics for detecting issues with privileged accounts. Although I haven't seen a huge amount of alerts. We have a quarterly QBR, and they mentioned it the day before the QBR and noticed an alert pop up. One of the key things for us is we have an annual pen test (an internal one), that's not as involved as a full red team. But, it's enough for the pen test to sit with the SOC guys, then we put the different tool sets together, what they're doing, and how that reacts to our Vectra, SIEM, and endpoint AV. To see what picks up where, so it gives us an ability to check those tool sets that we have. From a Vectra point, it will pick up a number of different things. But, it will also miss a number of different things. That's how pen testers work. They work covertly. So, it's really good for us to see what we can do and what we can't. Then, that feedback goes back to Vectra. We say, "Okay, well why didn't we pick up this?" They'll come up with a reason or they'll take it away and find something out about it. That's really good and a nice part of the service. We get to check to make sure the tool sets are working, but we also provide feedback and they're very open to that type of feedback. I believe the solution has increased our security efficiency. It's hard to prove without having a direct attack. But, I get challenged about ransomware from my board, to say, "How do we defend against ransomware?" That's a big topic. One of the key things was when Vectra went in, it saw a developer run a script, which essentially changed the names for a number of files and put a different extension on, but they were doing some development type work. That's how their script ran, and it identified that as ransomware, which is a great thing to say. Although there was no encryption or malice involved, it did create new files, rename files, and delete old files, which essentially is what ransomware does anyway. It followed the same sort of logic to it, I can report that back. "We do have some protection. It wouldn't stop it. But we could limit the amount of damage that it may do." I don't know about other companies, but I get the feeling most people look to identify rather than block. We're not a high-end bank. We are not going to stop people working. We're going to investigate what they're trying to do. That's just our risk appetite. We have to work. Unless it's absolutely 100 percent, we won't stop them. We would just look at it afterwards. So, all our alerting, we don't have any orchestration at the back of it to say, "Okay, if this happens, then I'm going to play that port in a firewall or I'm going to drop that from there." We won't do that. Humans will all be part of that process. We'll get a call, then we will make a crisis management team decision, etc. That's how we operate. If, for instance, our AV doesn't pick it up. I think that is where Vectra will come in. So, if somebody gets infected and maybe hasn't picked it up. That's where, if that worm spread and our endpoint signatures weren't up-to-date, they went into zero day, and nobody knew about it. Vectra would give us that opportunity. It would potentially give us something that would say, "Well, this is not normal. This machine does not communicate with all these other machines like it is now." That's where we see it coming in. It gives us that extra chance to stop a disaster before it happens, or at least limit the amount of potential output of damage that that an incident can do. Zero days are always very difficult. If the AV vendor doesn't know about it, it's not going to be able to tell me about it, stop it, quarantine it, or do anything. Having a tool set like this, which monitors network traffic for anomalies, it gives us that chance. I can't say that it definitely will pick it up, but there's another opportunity for us to reduce the amount of damage that can be done. View full review »

We have a limited use of Vectra Privileged Account Analytics for detecting issues with privileged accounts at the moment. That is primarily due to the fact that our identity management solution is going through a process of improving our privileged account management process, so we are getting a lot of false positives in that area. Once our privilege account management infrastructure is fully in place and live, then we will be taking on more privileged account detections and live SOC detections to investigate. However, at the moment, it has limited applicability. We have a lot of technically capable people with privilege who are able to do things they should or should not be able to do, as they're not subject-matter experts when it comes to things like security. They may make a decision to implement or download a piece of software, implement a script, or do something that gets the job done for them. However, this opens us up to major security risk. These are the types of activities that the tool has been able to identify, enabling us to improve communication with those individuals or teams so they improve their business process to a more secure or best practice approach. This is a good example of how the solution has enabled us to identify when people are engaging in legitimate risky activities, and we're able to identify and engage with them to reduce risk within the network. It has enabled our security analysts to have more time to look at other tools. We have many tools in place, and Vectra is just one of them. Their priority will always be to deal with intrusion attempt type of alerts, such as malware compromise or misuse of credentials. Vectra was able to simplify the process of starting a threat hunting or investigation activity on an anomaly. Previously, we weren't able to do this because the amount of alerts and volume of data were just too large. Within our security operations, they can now review large volumes of data that provide us with indicators of compromise or anomalous behaviour. By reducing false positives, we are able to take on more procedures and processes. We have about seven different tools providing alerts and reporting to the SOC at any one time. These range from network-based to host-based to internet-based alerts and detections. We are more capable to cover the whole spectrum of our tooling. Previously, we were only able to deal with a smaller subset due to the sheer workload. In some regards, I find that Vectra probably create more investigative questions. E.g., we need to find answers from other solutions. So, it is raising more questions than it is specifically answering. However, without Vectra, we wouldn't know the questions to ask in the first place. We wouldn't know what anomalies were occurring on our network. Vectra data provides us with an element of enrichment for other detections. For example, if we see a detection going onto a single host, we could then look at that activity in Vectra to see whether there are suspicious detections occurring. This would give us the high percentage of confidence that the compromise was more severe than a normal malware alert, e.g., destructive malware or commander control malware enabling someone to pivot horizontally across the network. Vectra provides us with that insight. This enables us to build up an enriched view quickly. View full review »

What we have seen over the course of the three to four months it has been in place is that it has not found anything bad. That's good news because nothing specific has happened. But we have identified a lot of misconfigurations as well as some information on how applications are working, which was not known earlier. The misconfigurations that became known because of Vectra have been corrected. It has given us the opportunity to understand some of the applications better than we had understood them before because some of the detections required triage and, while triaging, or in that investigation, we found how applications work. That is one of the main benefits. We did a red team penetration exercise and almost all the pen activities were picked up by Vectra. That is another big benefit that we have seen through the deployment of the device. Apart from the network traffic, a lot of the privileged accounts get monitored. It focuses on the service, the machine, and the account. We have seen many of the privileged accounts flagged with alerts whenever they're doing any activity which they do not normally do. We can see that it is the admin accounts or our support team accounts where the activity is happening. It is important because any privileged access which sees increased activity becomes a cause for suspicion. It's something that we need to be watchful for. It's a very useful feature because a privileged account can propagate more easily than an account that is not privileged. These are all examples of the kind of information which is of great value, information that we didn't have earlier. The detections, as well as the host ratings, allow us to focus in cases where we are pressured for time and need to do something immediately. We can focus on the critical and high hosts, or on the detections that have a very high score. If you do a good job in the rules and policy configuration, the alerts are not too numerous. A person can easily focus on all the alerts. But as of now we focus on the critical, high, and medium. The scoring and the correlation really help in focusing the security operations. While I wouldn't say Vectra AI has reduced our security analyst's workload, it allows him to focus. It's a new tool and it's an additional tool. It's not like we implemented this tool and removed another one. It doesn't necessarily reduce his total time, but what it definitely does is it allows him to prioritize more quickly. Previously, he would be looking at all the other tools that we have. Here, it allows him to focus so things of serious concern can be targeted much faster and earlier. The existing tools remain. But Vectra is something to help give more visibility and focus. In that sense, it saves his time. Vectra is very good for automated threat-hunting, so you get to pick out things faster. All the other tools give you a volume of data and you have to do the threat-hunting manually. Also, the technical expertise required to do the hunting part is much less now, because the tool does it for you. I wouldn't say that it has moved work from tier 2 to tier 1, but both of them can use their time and efforts for resolving problems rather than searching for actual threats. You cannot do away with tier 2 people, but they can have a more focused approach, and the tier 1 people can do less. It reduces the work involved in all their jobs. In addition, it has definitely increased our security efficiency. The red team exercise is a very clear-cut example of how efficiency has been enhanced, because none of the other tools picked these things up. Vectra was the only tool that did. It makes our workforce more efficient, and makes them target the actual threats, and prioritizes their efforts and attention. Whether that eventually leads to needing fewer people is a different question. Quantifying it into a manpower piece is probably more an HR issue. But improved efficiency is definitely what it provides. If I needed three or four tier 2 people before, I can manage with one or two now. And Vectra has definitely reduced the time it takes us to respond to attacks. It's a significant reduction in time. In some cases, the key aspect is that, more than saving time, it detects things which other tools don't. It helps us find things before they actually cause damage. The other tools are more reactive. If your IPS and your signatures are getting hit, then you're already targeted. What Vectra achieves is that it alerts us at the initial phase, during the pre-damage phase. During the red team exercise we had, it alerted us at their initial recon phase, before they actually did anything. So more than saving time, it helps prevent an attack. View full review »

It is doing some artificial intelligence. If it sees a server doing a lot of things, then it will assume that is normal. So, it is looking for anomalous behavior, things that are out of context which helps us reduce time. Therefore, we don't have to look in all the logs. We just wait for Vectra to say, "This one is behaving strange," then we can investigate that part. We have implemented it fully now. We have done some training and filtering on it. Now, every alert that we see means that we need to investigate. It sees roughly 300 events a day. The majority are normal behavior for our company. So, there are about 10 to 15 events a day that we need to investigate. The solution triages threats and correlates them with compromised host devices. It looks at a certain IP address, and if you're doing something strange, then it will give us an alert. E.g., normally John Doe is logged into it for four days, going to server XYZ. If all of a sudden, it's in a different timescale, going to server B, then it will send us an alert. We have privileged accounts. They have a specific names, and if I see those names, then I investigate a bit more thoroughly. That's our policy. I don't know whether Vectra does anything different with them. The solution gives us more tickets. If we did not have Vectra, we wouldn't have those tickets. So, it's actually increasing them. However, it is improving our security with a minimum amount of work. That's the whole purpose of the device. We have 10 to 15 events that we need to look into a day, and that is doable. The solution creates more work for us, but it is work that we are supposed to do. We need more FTEs because we need more security. View full review »

The solution captures network metadata at scale and enriches it with security information. We store metadata for three months. Just to be able to scale the amount of information that we collect on the networks is a problem in itself. We have our SIEM solution that collects all of these logs. Making sure these logs are still sending, that these devices are still sending to our main SIEM, are issues. For Vectra, even with three months of retention, with the environment we have, we have never had issues accessing this network data. On top of that, if there are any issues, the support team is amazing in providing feedback and fixing them. It has actually increased our security analyst workload, but in a good way. It has reduced the amount of stuff that we used to look at, and has allowed us to re-approach our C-CERT from signature-based detections to more behavioral-based detections. It has reduced the amount of boring work and work that is on the host, to more thought-provoking work based on behavioral data. We're now able to approach our C-CERT from a risk perspective and a numbers perspective. It has reduced that boring work drastically and it reduces the time to investigate incidents in general. While it has definitely added a bunch of incidents for us to look at, it has reduced the workload of how we work those incidents. It makes them not only much easier to engage with and easier to visualize, but also enables us, as analysts, to work in a much more efficient and simple way. Vectra has also helped move work from our Tier 2 to our Tier 1 analysts. Eighty percent of our Tier 1 analysts are doing Tier 2 work. Finally, the solution has reduced the time it takes us to respond to attacks. It has gone from on the order of hours to less than 10 minutes to 30 minutes. View full review »

We have 89,000 concurrent IPS that we're analyzing and it's distilled it down to under 1,000 IP addresses that warrant deeper investigation. It's filtering out 99 percent of the traffic that would otherwise be noise, noise that we would never get through. The solution captures network metadata at scale and enriches it with security information, but that's because we are using the API calls to inject our CMDB data into the brain. It speeds things up quite significantly. Being an enterprise, sometimes it can take a day or two just to find the person responsible for looking after a particular server or service. This way, the information is right there at our fingertips. When we open up the GUI, if we have a detection we look at the detection and see the server belongs to so-and-so. We can reach out to that party directly if we need to. It streamlines the investigation process by having the data readily available to us and current. Each one is unique, but typically, from initial detection to completion of validation (that it's innocuous or that there's something else is going on) it's within 24 to 48 hours It also provides visibility into behaviors across the full lifecycle of an attack in our network, beyond just internet gateway. It gives us visibility for when something is inside the network and it's maybe doing a lateral movement that it wouldn't normally be doing. Or if we have a system that has suddenly popped up on the network and we can see that it's a wireless router, for example, we pick that up right away. We can see it and we can deal with it. If people put unauthorized devices on the network — a wireless router from home — we can pick that up right away and deal with it. In addition, Vectra triages threats and correlates them with compromised host devices. We can do a search based on the threat type and get the host. It streamlines things and makes it faster to get to the root cause of an issue. And while it hasn't reduced the security analyst workload in our company, it has reduced the workload in that analysts are not having to look at stuff that absolutely means nothing. There is still a lot to do, but it has allowed us to focus better on the workload that needs to be done. It has also increased our security efficiency. It has reduced the time it takes us to respond to attacks by 100 percent. If you're not aware of it you can't respond to it. Now, it's making us aware of it so we can respond to it, which is a 100 percent improvement. The solution enables us to answer investigative questions that other solutions are unable to address. We will detect the fact that there is some suspicious domain activity going on — a DNS query is going out to MGAs and it really shouldn't be. The other systems are just passing that through, not even realizing that it shouldn't be happening. We see them and we can take action on them. View full review »
