Network visibility has transformed how we detect nation state threats and protect critical industry

Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale. However, I think with a lot of the artificial intelligence that they are building in, it is getting a lot easier to query in the platform. I would definitely encourage them to continue down that path where anybody can hop into the platform and start running queries, whether it is a simple instruction like I want this, and an artificial intelligence process can actually build the query and do it. I think that would be super powerful. Cyber skill sets are in high demand, and there is a huge backlog in cyber talent. We cannot fill all the positions we need. The easier we can make these cyber systems for people to pick up and be effective on, I think is really key. Explainability of data is hyper important. In the past few artificial intelligence related updates we have gotten from Corelight, that has been one of the first questions our team has asked every time or that I have asked: show me what the model is doing, show me how it came to this analysis. Within Investigator platform, they are able to walk through and see exactly what data the artificial intelligence pulled from where and why it did what it did as far as making its suggestions. They have definitely built their system with artificial intelligence in mind up front, and having that openness as one of the key features of any of their artificial intelligence and machine learning processes in the platform is important. The issue with black boxes is obviously hallucinations from artificial intelligence and just not being able to trace to ground truth. When we are talking about these cyber incidents and being able to do forensics, you need to be able to pinpoint and tie everything together, and black boxes really obscure that and prevent you from doing so. Corelight has done a really good job of making sure that everything is explainable and everything is mapped when it comes to leveraging any of their artificial intelligence features.

Monitoring has improved data loss detection and now spots abnormal internal file transfers quickly

In my understanding, the best feature Darktrace offers is the identification of copying files, which acts as a DLP, and it is a main concern for companies because users sometimes copy data outside without knowing, especially those without a technical background. When I mention the DLP-like feature and file copying detection, the alerts have been very timely, as we get an alert within a couple of minutes, which is excellent. Even if some developers are working after hours and copying files, our SOC team detects this, and most of the time they call us so we can identify the users. The alerts are quite accurate and proactive.

"It's an expensive solution and the price could be reduced."

"Machine learning could be a good improvement, but it's very costly."

"In the next release, building a graphical user interface would be helpful."

"Before Corelight recently started pushing some of the agentic features, querying at times could be a little difficult, depending on your mastery of log scale."

"Corelight hasn’t added features in a long time."

"The product is considered expensive compared to others."

"Its threat analyzer could be better. It should also have agents."

"They just need to work on their price."

"A reporting portal could be a great addition to help customize reports."

"Although we haven't detected any network threats since implementing Darktrace, we are unsure of its efficacy. It would be beneficial if the solution could offer additional details to the user regarding any potential or prevented threats. Additionally, there could be better search tools and integration."

"It would be helpful if they could recognize incidents and simplify the customer's challenge to identify what is happening."

"The interface and dashboards could be improved for ease-of-use."

"I'd love them to see maybe covering the cloud a bit more."

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."

"Prior to negotiating, Darktrace offered their appliance and service for $80,000 per year."

"I am using a demo of Darktrace for deployment and testing which is free."

"The pricing is quite high, estimated at around $350,000 per year."

"It is a very expensive product."

"The pricing is very flexible for Darktrace. Sometimes, a customer does not have the appropriate budget, but Darktrace can handle that. They offer monthly payments, so the customer can acquire the solution very easily."

"I'm unfamiliar with the exact cost, but we have a yearly license and had to pay for Darktrace's services before the deployment. The product is very expensive, so some organizations can't afford to pay the total amount directly, meaning they often seek a partner or pay in installments, which increases the price more."

"All of the other modules, such as the licensing modules, are on par. It's one for one."

"When it comes to large installations, it can be expensive, but for small accounts it's fine."
