Network Monitoring

24:7 Threat Detection & Response

See Every Packet. Stop Every Threat.

You can't stop what you can't see. We make sure you see everything.

Most breaches don't announce themselves with a siren. They move quietly and deliberately through your network, masquerading as normal traffic until a foothold becomes a full compromise. Xenex deploys Network Intrusion Detection System (NIDS) monitoring across your routers, switches, firewalls, servers, and workstations by continuously inspecting traffic in real time for attack signatures, behavioral anomalies, and threat patterns that indicate malicious activity. From reconnaissance probes to lateral movement to data exfiltration attempts, Xenex surfaces the indicators that matter and delivers immediate alerts to your security team. By the time a threat actor believes they're operating undetected inside your environment, your team already knows they're there.

Know exactly what's flowing across your network. Monitor what has no business being there.

Device uptime tells you your network is running. NetFlow tells you what it's actually doing. NetFlow analysis reveals the full conversation map of your network — who is communicating with whom, what volumes of data are moving between which endpoints, and whether those traffic patterns align with what your business should be doing. Xenex collects and analyzes NetFlow data across routers, switches, firewalls, and servers, establishing behavioral baselines and flagging deviations that could indicate insider threats, compromised devices, or unauthorized data movement. When a workstation suddenly begins transferring gigabytes of data to an unfamiliar external address at 2 am, Xenex makes sure that conversation doesn't go unnoticed.

Speak your network's language. Catch the conversations that shouldn't be happening.

Your network runs on protocols and every legitimate application, service, and device has a predictable way of communicating. When something starts behaving outside those norms, using unexpected protocols, communicating on non-standard ports, or generating traffic patterns that don't match its role, it's rarely a coincidence. Xenex performs continuous deep protocol analysis across your firewalls, routers, switches, servers, and workstations, building a clear picture of normal network behavior and alerting your team to anything that deviates from it. Whether the cause is a misconfigured application, a compromised endpoint, or an attacker attempting to blend into legitimate traffic, protocol-level visibility ensures the anomaly doesn't stay hidden.

Control what enters and leaves your network down to the packet level.

Your network perimeter is only as strong as the rules governing what crosses it — and those rules are only effective if they're actually working as intended. Packet filtering gives your organization granular control over traffic flows across firewalls, routers, and switches, blocking unauthorized connections and enforcing the traffic policies your security architecture depends on. Xenex monitors packet filtering rules and enforcement across your entire infrastructure in real time, validating that your controls are functioning correctly and alerting your team immediately when traffic attempts to bypass, circumvent, or exploit gaps in your filtering policies. Across firewalls, routers, switches, and servers, nothing crosses your network boundary without scrutiny.

When you need the full picture, every packet tells a story.

Alerts tell you something happened. Packet capture tells you exactly what. When a serious security incident occurs, the ability to reconstruct the full sequence of events — what data moved, which systems were involved, what commands were executed — is the difference between a thorough investigation and an incomplete one. Xenex captures and retains full packet data across your network infrastructure, providing your security team with the forensic evidence needed to investigate incidents, validate threat intelligence, support legal or regulatory proceedings, and demonstrate due diligence to auditors. For organizations operating under compliance frameworks that demand demonstrable security controls, full packet capture isn't just a forensic tool — it's an organizational safeguard.

Frequently asked questions

Network Intrusion Detection System (NIDS) monitoring involves the continuous inspection of network traffic for attack signatures, behavioral anomalies, and threat indicators. Xenex deploys NIDS across routers, switches, firewalls, servers, and workstations to analyze traffic in real time and alert security teams the moment suspicious activity is detected, whether that's a reconnaissance scan, lateral movement, or an active exfiltration attempt.
NetFlow analysis examines the metadata of network conversations, capturing source and destination addresses, traffic volumes, protocols used, and timing patterns — without inspecting the full packet payload. This gives security teams a high-level map of all communication occurring across the network. Xenex uses NetFlow data collected from routers, switches, firewalls, and servers to establish behavioral baselines and identify anomalies such as unexpected external connections, unusual data volumes, or unauthorized lateral movement between internal systems.
Signature- based detection identifies known threats. Protocol analysis identifies behavior that doesn't conform to how legitimate applications and devices are supposed to communicate. The focus is on catching threats that have no known signature yet. Xenex analyzes protocol behavior across firewalls, routers, switches, servers, and workstations, flagging deviations such as unusual port usage, protocol tunneling, or communication patterns inconsistent with a device's expected role on the network.
Packet filtering is the enforcement of rules that control which traffic is permitted to enter or leave a network based on defined criteria such as IP address, port, and protocol. Xenex monitors packet filtering enforcement across firewalls, routers, and switches in real time. Then validates that traffic policies are functioning as intended and alerts security teams when traffic attempts to bypass filtering controls or when rule misconfigurations create unintended gaps in protection.
Full packet capture records the complete content of network traffic, every byte of every packet, rather than just metadata or summaries. It is most valuable during incident response, forensic investigations, compliance audits, and legal proceedings where a complete, accurate record of network activity is required. Xenex captures and retains full packet data across your network infrastructure, ensuring that when a serious incident occurs, your security team has the evidence needed to reconstruct exactly what happened.

NetFlow
and packet capture serve complementary roles. NetFlow provides broad, continuous visibility
into traffic patterns across routers, switches, firewalls, and servers. This is ideal for detecting
anomalies at scale. Full packet capture provides the forensic depth to investigate those
anomalies in detail. Xenex combines both, using NetFlow analysis to surface suspicious activity
and packet capture to provide the evidence needed to confirm, investigate, and respond to
threats with precision.

Yes. Insider threats often manifest as unusual traffic patterns rather than known attack signatures. Examples include a user accessing systems outside their normal scope, large volumes of data being copied to external destinations, or devices communicating with services they have no business reason to reach. Xenex analyzes NetFlow data, protocol behavior, and packet-level activity across your entire infrastructure, establishing behavioral baselines for all devices and users and alerting security teams when activity deviates in ways that could indicate malicious or negligent insider behavior.
Many compliance frameworks, including PCI-DSS, HIPAA, NIST, and SOC 2 require organizations to demonstrate continuous monitoring of network traffic, logging of network activity, and the ability to investigate security incidents. Xenex supports these requirements through NIDS monitoring, NetFlow logging, protocol analysis, and full packet capture across firewalls, routers, switches, servers, and workstations, providing the audit-ready evidence and documented controls that regulators and auditors require.
Data exfiltration attempts typically generate detectable signals — unusual outbound traffic volumes, connections to unfamiliar external destinations, the use of non-standard protocols or ports to bypass controls, or large transfers occurring outside business hours. Xenex combines NIDS signature detection, NetFlow anomaly analysis, and protocol inspection across routers, firewalls, servers, and workstations to identify these patterns in real time, alerting security teams before sensitive data leaves the organization.
NIDS monitoring analyzes network traffic in real time against known attack signatures and behavioral rules, generating alerts when threats are detected. It is designed for speed and continuous detection at scale. Full packet capture records the raw content of all network traffic for retrospective analysis and forensic investigation. Xenex deploys both capabilities together, using NIDS for active threat detection across your live network and packet capture to preserve the complete evidence record your team needs when a deeper investigation is required.
