The Challenge

Traditional Tools Can't See What Ransomware Does Until It's Too Late.

Ransomware doesn’t announce itself. It moves laterally, escalates privileges, maps out your file systems, pulls data, and locks everything down, all in a matter of minutes. Most security tools don’t even trigger until the damage is done. By then the attacker’s already holding your files hostage.

Here's why detection fails:

  • Signature-based tools only catch malware they've seen before, missing new variants and zero-days
  • Endpoint detection alone misses network-based threats and lateral movement between systems
  • Log analysis happens too late to stop encryption in progress
  • No visibility into encrypted traffic where command and control happens
  • Alerts fire in isolation without cross-domain context to confirm a real attack
  • Ransomware operators use living-off-the-land tactics that blend into normal activity
  • By the time human analysts see the alert, encryption is already underway

The Solution

The NetWitness Approach

Here’s the shift NetWitness makes: instead of waiting for a signature match, it watches for the behavior that comes before encryption. Combine that with full network visibility and you’re catching ransomware during reconnaissance and lateral movement, not after the fact. That’s the window where you can still do something about it.

Behavioral Detection of Malware Activity

Known signatures still matter, and NetWitness catches those. But it’s also watching for the things signatures miss: odd file access patterns, memory injection, C2 callbacks, processes doing things they shouldn’t. Commodity malware gets caught. So does the targeted stuff that’s built specifically to slip past signature tools.

Ransomware Reconnaissance Detection

Before anything gets encrypted, operators spend time scoping out the network. That recon phase leaves traces, credential dumping, privilege escalation attempts, file systems getting scanned faster than any normal process would scan them. NetWitness picks up on this while it’s still happening. You’re stopping an attacker who’s still planning, not one who’s already mid-encryption.

Encrypted Traffic Visibility

Attackers hide C2 communication inside encrypted channels because it works. NetWitness doesn’t need to decrypt anything to spot it though. Traffic patterns, connection behavior, metadata, these give away attacker infrastructure long before encryption starts.

Cross-Domain Attack Reconstruction

Ransomware doesn’t stay confined to one layer. It touches network and endpoint both, so NetWitness pulls together network activity, endpoint telemetry, and logs into one timeline. Initial compromise, lateral movement, privilege escalation, the run-up to encryption: you see it as one campaign instead of a pile of disconnected alerts.

How NetWitness Works

The architecture behind catching malware and ransomware before encryption happens:

Capture Network & Endpoint Telemetry

Full packet capture plus behavioral data from your network, endpoints, and logs, flowing in continuously.

Apply Behavioral Analytics

Machine learning flags what's off: lateral movement, encryption activity kicking in, data heading somewhere it shouldn't, recon tactics.

Correlate Across Domains

Network activity gets checked against endpoint events and logs. That's how you confirm it's a real coordinated attack and not just noise.

Surface Actionable Alerts

Alerts come through with the evidence already attached, compromised user IDs, affected systems, the network connections, the behavioral context behind it.

Enable Instant Response

Analysts don't start from scratch. They can reconstruct the attack, find the infected systems, contain the lateral movement, and isolate what's compromised right away.
