Network coverage

24x7 monitoring for a secure company network

Your firewall is great, but what about the traffic inside? We monitor to secure your network 24x7, finding the tactics that signal an attack.

Our difference

Find the signal in your network static

Our detection strategy gets more from your network security tools, focusing on attacker behavior to secure your company network from advanced threats.

Detect C2, lateral movement, and network discovery

We analyze internal traffic patterns, ingesting flow data and content to spot the tell-tale signs of attackers moving through your network.

Connect network threats across attack surfaces

We use network alerts to enrich other investigations from our SOC across all your other surfaces, linking suspicious domains to a compromised user account or device.

Cover critical MITRE ATT&CK network tactics

We focus on post-compromise tactics like discovery, lateral movement, and command & control to stop intruders.

Network security approach

How we secure your company network infrastructure

We pull the most useful signals from your existing network security stack—Palo Alto Networks, Zscaler, Darktrace, and more—ingesting traffic flow data and content. Our detection logic then helps spot unusual activity that indicates compromise. Alerts are enriched with IP/domain tracking to identify malicious patterns and see which assets or users are involved, providing critical context for any investigation.

Ruxie automatically pulls network behavior and web traffic data into alert context to correlate against endpoint and cloud signals, mapping lateral movement and command-and-control communication before investigation begins.

MDR Benefits

Why Expel for network security?

It’s not just about network alerts. We turn that visibility into a strategic advantage for your entire security operation.

Get more from your network security investment

We don’t just forward alerts. We build layered, high-fidelity detections on top of your tools to deliver powerful outcomes.

Fewer false positives, less chasing ghosts

Our detection engine filters out the noise. Your team spends less time chasing down phantom threats and more time focused on what’s real.

Connect the dots between attack surfaces

Our team gets the full story. We use network data to enrich other alerts, like seeing the C2 traffic behind a suspicious login.

Get answers, not just another alert stream

You get clear findings with plain-English explanations and step-by-step instructions so you can act fast, and with confidence.

Continuously updated detection logic

Our detection logic is continually refined based on real-world threats, keeping your company network secure against the latest attacker tactics.

Frequently asked questions

How does Expel provide network security monitoring?

Expel integrates with network security tools including firewalls, IDS/IPS, and NDR platforms from Palo Alto Networks, Cisco, Fortinet, and Zscaler to monitor for lateral movement, C2 traffic, data exfiltration, and network-based intrusions. Network signals are correlated with endpoint, identity, and cloud telemetry.

What network threats does Expel detect and respond to?

Expel detects network-based threats including lateral movement between systems, command and control (C2) traffic to attacker infrastructure, data exfiltration over network channels, DNS tunneling, and network-based persistence mechanisms. Network signals are correlated with endpoint, identity, and cloud telemetry to surface attack chains spanning your environment.

Does Expel integrate with Palo Alto Networks, Fortinet, or Zscaler for network security?

Yes. Expel integrates with Palo Alto Networks (Panorama, Cortex XDR), Fortinet (FortiGate), Cisco (ASA, Firepower), Zscaler (ZIA/ZPA), and other network security platforms. We ingest firewall logs, network alerts, and proxy data directly into Expel Workbench where analysts correlate network signals with endpoint and identity telemetry.

How does Expel's network security monitoring support a zero-trust architecture?

Zero-trust assumes breach and requires continuous verification of users, devices, and network traffic. Expel supports zero-trust by monitoring the identity and network enforcement layers, detecting when legitimate-looking credentials are used from anomalous locations, or when a trusted device behaves unexpectedly.

How does Expel secure business networks for remote and hybrid workforces?

Remote and hybrid workforces expand the network attack surface beyond traditional perimeter controls. Expel monitors and correlates across the identity and endpoint layer, and network security tools including VPN and ZTNA platforms to detect anomalous access patterns from remote users, such as impossible travel or connections from compromised devices.
