Challenges
Ransomware Thrives in the Gaps of Network Visibility
Ransomware attacks rarely fail because defenders miss an alert. They succeed when attackers move laterally inside trusted network zones and security teams lack the visibility and evidence needed to prove what happened, determine scope, and act decisively.
Most organizations rely on disaggregated detections, logs, and inferred signals that provide limited visibility into east–west traffic, encrypted command-and-control communication, and data exfiltration activity.
When investigation-grade evidence is unavailable or fragmented, Mean Time to Knowledge increases, response slows, and business impact escalates.
Outcomes That Matter
Close the Gap Between Detection and Response
Expose east-west ransomware spread
Reveal lateral movement and internal traffic patterns that are often invisible to log-only approaches.
Scope impact precisely and contain with confidence
Identify affected hosts, sessions, and behaviors so teams take targeted action instead of broad shutdowns.
Stop the attacker before exfiltration or encryption.
Don’t just identify, stop the malicious activity before the attacker meets their objective.
NETSCOUT’s Solution and How It Delivers Value
Evidence-Driven Ransomware Detection and Response
The NETSCOUT solution can detect and block ransomware at the early stages (before data exfiltration or encryption) and accelerate investigation after a successful attack.
NETSCOUT’s Omnis Cybersecurity and Arbor DDoS Protection products provide continuous packet-level visibility across on-prem, virtual, and hybrid environments. At the source, they apply multidimensional threat analytics, including indicators of compromise, custom policies, signatures, and behavioral anomalies, to identify ransomware-related behaviors before encryption.
- Initial access and suspicious internal access attempts
- Lateral movement and east–west propagation
- Command-and-control communication
- Anomalous data exfiltration activity
Upon detecting this pre-ransomware activity, the solution can block further activity at the network perimeter using NETSCOUT Arbor Edge Defense or a firewall.
Full integration with your security stack (e.g., SIEM/SOAR, EDR) enables analysts to remove compromised endpoints and conduct historical packet-level investigation before, during, or after the ransomware attack.
The result is that security teams can detect and block ransomware attacks at their earliest stages, before data exfiltration or encryption occurs, and accelerate ransomware investigation and response with always-on historical evidence.

Frequently Asked Questions
How does Omnis Cyber Intelligence detect ransomware without relying on endpoint agents?
Omnis Cyber Intelligence analyzes real network traffic using packet-based DPI and behavioral analytics, allowing detection of ransomware activity even when endpoint signals are incomplete or unavailable.
Can Omnis Cyber Intelligence detect ransomware moving laterally inside the network?
Yes. Omnis Cyber Intelligence provides continuous east–west visibility to expose lateral movement, internal propagation, and suspicious internal access patterns.
How does Omnis Cyber Intelligence integrate with our existing SOC tools?
Omnis Cyber Intelligence integrates with SIEM, XDR, SOAR, and EDR platforms through Framework for Extensible Ecosystem Integrations and Dispatch (FEED), enriching existing workflows with packet-grounded evidence for faster investigation and response.
