Corelight Sensor v29.1 and Fleet Manager v29.1.1 fundamentally expand what a Corelight Sensor delivers. The release turns existing network evidence into a shared source of truth for SecOps, NetOps, triage, and forensic investigation. Network performance monitoring and asset classification unlock new value from traffic you're already collecting.

Every packet flowing through a Corelight sensor contains both security-relevant data and performance-relevant data. Until now, Corelight has focused exclusively on extracting security value from network traffic: connection logs, protocol analysis, and threat detections. But the same traffic that reveals lateral movement also reveals TCP latency. The same DNS queries that surface potential C2 channels also reveal resolution timing.

Weekly cyberattacks now average 1,968 per week, up 18% year over year and 70% since 2023, while security teams still take an average of 277 days to identify and contain a breach, according to SentinelOne's cybersecurity statistics roundup. That combination changes the meaning of “real time” in security. It no longer means a dashboard that updates quickly. It means building detection and response so attackers don't get months of freedom between first access and containment.

Security threats don’t announce themselves. They can slip in through vulnerabilities in your code, hide in third-party libraries, and exploit gaps that your team hasn’t had time to patch yet. That’s why application threat detection isn’t just a nice-to-have; it’s the foundation of a modern security program.

In 2024, ransomware was publicly disclosed in more than 5,600 attacks worldwide, with over 2,600 victims in the United States alone. The same reporting says the FBI's 2024 IC3 report logged 3,156 ransomware complaints, an 11.7% increase from the prior year, which is a useful reminder that this isn't a niche malware problem. It's a persistent operational risk that keeps showing up across sectors and environments (Fortinet's ransomware statistics summary).

There is a saying you will hear from veterans in the Black Hat Network Operations Center (NOC): “Threat hunting on the Black Hat network is like trying to find a needle in a stack of needles." With dozens of training classes running live exploit chains, capture-the-flag traffic, and researchers probing every corner of the internet, our Corelight sensors generate a rich set of Zeek logs, many of which can look suspicious in varying degrees.
