Network visibility is the linchpin for successful cybersecurity.

Your Network Is Already A Security Platform

You just need visibility. While tools that focus on threat signatures and perimeter security are important, they are not enough. To maintain a consistently strong security posture in the face of advanced threats, you need full visibility into the common denominator that every threat relies upon: the network.

Today's Cybersecurity Tools are Fighting Yesterday's Battles

As quickly as cybersecurity practitioners learn to recognize and protect against the latest methods of attack, hackers come up with more sophisticated tools for compromising systems, resulting in an endless war of escalation. Unfortunately, the hackers have time on their side. Even as new vulnerabilities are created or discovered, there remains a treasure trove of known vulnerabilities that can still be used against unpatched systems.

Cybersecurity Tools of Today

I don't know what the next threat will be, but I guarantee you one thing: It will involve two hosts communicating over the network.

Here is What You Need to Make it Work

Total Visibility

North-South, East-West Visibility

Enterprise networks are big, complex, and multifaceted. To take advantage of the security potential in your network, you need to be able to see into every transaction that passes across it, including the "east-west" traffic between hosts and tiers within your network.

Real Time Insights

Real-Time Insight

Looking at the details of individual transactions is useful in after-the-fact forensics, but it won't help you spot a threat in the first place. Machine learning-driven analysis of structured L2 – L7 wire data, provided in real time, is a key requirement for tapping into your network's security potential.

Deep Analytics

Deep Analytics with Long Lookback

Threat actors don't just break in and immediately trash the place. They wait for the perfect moment to strike. You need deep analytics going back months to understand the source of threats, the scope of an incident, and how to root attackers out for good.

Signatures vs. Behavior: What the Network Gets You

Many security tools rely on profiles of known threats. Firewalls, blacklisting services, and old-school antivirus work this way. These can add value, but they all share a weakness: they're focused on what's known. They take what they see in the world, and reassure you: "At least this won't happen to you on our watch."

In contrast, analyzing the network traffic means you're looking at actual behavior, not scanning for signatures of known threats. The combination of complete visibility, real-time insight, and long lookback allows you to detect malicious behavior as it happens, as well as dig up forensic evidence of attacks in the past. This alone is enough to justify using wire data for security.


  • Relies on past knowledge and assumptions to recognize threats.
  • Looks for specific traffic patterns and byte sequences in network traffic.
  • Signature database needs to be frequently updated.

Observed Behavior

  • Detects anomalous events based on actual observations in your environment.
  • See malicious behavior as it happens—even zero-day attacks.
  • Records all network activity, not only flagged events.

How ExtraHop Can Help

Threat Detection

  • Machine learning-driven anomaly detection for applications, databases, authentication, and more.
  • Detect malicious/anomalous L2 – L7 activity on the network at each stage in the attack lifecycle.
  • Empower security analysts and threat-hunt teams with real-time visibility into all activity on the network.

Risk Identification

  • Identify risks, such as sensitive data passed in the clear and use of banned ports, protocols, and services (PPS).
  • Continuously monitor activity such as movement of data between zones and privileged user accounts.
  • Simplify audit reporting with continuous and pervasive monitoring of network activity.

Tool Integration

  • Automate intelligent firewall and Network Access Control (NAC) actions with a REST API.
  • Stream wire data to SIEM platforms for correlation and forensic investigation.
  • Improve analytics platforms by shifting from log data to wire data.

Customer Success


With ExtraHop and the SIEM we've built around it, our security guys have—at most—two windows they need to look at. One tells them what's going on, the other one tells them what has gone down and how to fix it. My goal is always to be within four clicks of any incident.
