Ransomware Prevention

Defend against ransomware with real-time network security analytics and investigation automation.

Ransomware Is Trending Up

  • Ransomware is growing at a yearly rate of 350%, up 15x in just 2 years.
  • An IBM survey found that 70 percent of businesses infected with ransomware paid up.
  • Ransomware damages exceeded $5 billion in 2017

Intrusion Defense Isn't Enough

Ransomware attacks succeed because of outdated systems, and because so many organizations rely on perimeter defense and signature detection—which means, once ransomware is inside their network, they're completely vulnerable.

Perimeter and end point defenses are crucial, but so is internal visibility: the ability to see bad actors moving in your east-west traffic. You need total visibility and smart behavioral analytics to detect and catch ransomware before it reaches critical files.

What Will Keep You Safe?

Total Visibility

Full Internal Visibility

In order to spot potential ransomware in time to quarantine infected systems, you must monitor all internal network traffic in real time, including "east-west" and encrypted traffic.

Real Time Insights

Behavioral Analytics

AI-driven behavioral analytics is the only way to detect potential ransomware attacks quickly enough that your team can quarantine infected systems before your business pays the price.

Deep Analytics

Deep Forensic Lookback

The average ransomware strain waits inside a compromised system for 200 days before attacking. You need deep analytics going back months to understand the true source and scope of an incident.

Prevent Ransomware with ExtraHop Reveal(x) Security Analytics


ExtraHop Reveal(x) auto-detects anomalies on the network, including the unique storage WRITE operations and file changes that are associated with ransomware. Incident response teams will be notified within minutes of a ransomware infection, and can automate response workflows to immediately quarantine infected systems.


Rapidly pinpointing attacks is crucial to stopping ransomware. ExtraHop Reveal(x) enables teams to identify attacks on NAS systems and shared file infrastructure in real time, as well as identify users and IP addresses associated with malware.


Armed with a live activity map of suspicious traffic moving through their enterprise, security teams can disconnect infected computers, block malicious IP addresses, and begin restoring files from backup.


Without ExtraHop, the investigation [into a new strain of ransomware] would have taken days or weeks, exposing the hospital to potentially catastrophic risk. Even the FBI was impressed when they found out how quickly we identified and contained the threat!
