Detecting silent sensors: Identifying EDR telemetry gaps with LimaCharlie

One of the most insidious security risks isn't a sophisticated attack, it's the endpoint that stops reporting. A sensor that appears enrolled but hasn't sent telemetry in hours or days represents a critical blind spot. Whether due to network issues, system shutdown, agent crash, or intentional tampering, these silent sensors deserve immediate attention.

Inside Fidelis' EDR Technology: What Sets Us Apart from Others

The endpoint detection and response (EDR) market has become crowded with solutions claiming comprehensive threat protection. Yet many organizations struggle with EDR platforms that force difficult tradeoffs: prevention-focused tools with limited forensic depth, investigation-heavy solutions that overwhelm lean security teams, or vendor-locked architectures requiring wholesale replacement of existing security infrastructure.

Going Beyond Prevention: Five Essentials for a True EDR Solution

The cybersecurity landscape has evolved, but many endpoint tools have not. Most still focus on known threats and signatures, blocking familiar malware and flagging suspicious files. They rely on static models that can only go so far. That approach worked for yesterday’s threats, but not for today’s attackers.

Detecting EDR Evasion with Corelight Open NDR

This video walks through how Corelight Open NDR helps security teams detect EDR evasion by delivering complete visibility across all network assets. Using a real-world scenario, the video demonstrates how anomaly detection uncovers suspicious activity, mapping events directly to MITRE ATT&CK techniques. The investigation process highlights the detection of an anomalous user agent, which ultimately reveals a Linux privilege escalation toolkit.

What does your firewall see that your EDR doesn't? Lessons from recent cyberattacks

The APT group known as Librarian Ghouls has managed to infiltrate the networks of technical universities and industrial companies in Russia, Belarus, and Kazakhstan without arousing suspicion. How did the gang get inside? By using legitimate logins and moving laterally through internal networks, relying on legitimate access credentials without generating alerts.
