Visibility & Monitoring Visibility & Monitoring

End-to-end visibility,
from network to application

"Where's it slow?" "Why did it fail?" — analyze network, application and cloud traffic in real time to identify problems instantly.

Why end-to-end visibility and observability, now?

With applications spread across on-premises, multi-cloud and SaaS, and users themselves scattered between the office, home and mobile, tracing the root cause of "it's slow" has become extremely difficult. Is it the network? The application? The SaaS provider? The internet path? When that boundary is unclear, incident response devolves into finger-pointing between vendors, and MTTR (mean time to recovery) stretches out indefinitely.

Expernet's observability solution combines Riverbed Alluvio (packet, session and app performance), Kentik (NetFlow, BGP and cloud traffic) and Stellar Cyber NDR (threat behavior analysis) to visualize everything from network to application, cloud and security in a single dashboard. "Where's it slow?" gets an immediate answer backed by data, not guesswork, and AI automatically detects and surfaces anomalies.

As an authorized partner of Riverbed, Kentik and Stellar Cyber, Expernet has delivered network and application visibility projects across manufacturing, finance, telecom and public-sector environments. We modernize fragmented monitoring tools into unified observability, with dashboard design, anomaly-detection rule tuning and ongoing operational support — all in Korean-language technical support.

No visibility, no control

Break free from IT operations that only find out about a problem after it happens, and build a proactive response system on real-time visibility.

Network traffic visibility
Collects NetFlow, IPFIX and BGP routing data to reveal who is sending how much traffic, and where. Automatically detects DDoS and anomalous traffic.
Kentik
Application performance monitoring
Measures response time, error rate and user experience for ERP, groupware and SaaS in real time. Turns "it's slow" complaints into an immediate, data-backed root cause.
Riverbed Alluvio APM
DNS/DHCP-based visibility
Every device generates DNS queries. Analyzing DNS data reveals internal traffic flow and even C&C malicious communication.
Infoblox BloxOne
Cloud traffic cost analytics
Analyzes AWS, Azure and GCP traffic flow and cost. Instantly identifies and optimizes the root cause of unexpected cloud data-transfer bills.
Kentik
Security event correlation
Combines anomalous network traffic with DNS query patterns to catch signs of internal breach and ransomware propagation paths early.
Kentik · Infoblox
WAN/SD-WAN performance monitoring
Continuously measures packet loss, latency and jitter across branch-to-HQ links, automatically reporting SLA compliance and sending alerts.

Riverbed Alluvio — NPM & APM NetFlow · Packet Analysis · User Experience

Riverbed Alluvio — NPM & APM

Alluvio NetIM automatically discovers and monitors network topology and device health, while Alluvio Aternity measures endpoint user experience in real time. Packet-level deep analysis pinpoints latency causes down to the millisecond.

  • NetFlow, IPFIX and sFlow collection and correlation
  • Packet-capture-based deep application analysis
  • Alluvio Aternity — endpoint DEX measurement
  • Cloud (AWS, Azure, GCP) traffic monitoring

Featured Outcome
Global manufacturer WAN performance fix
Packet analysis via Alluvio pinpointed the cause of overseas ERP latency to TCP retransmissions in the WAN link within 5 minutes — a 10x improvement after applying SteelHead.
Kentik Network Observability NetFlow · BGP · DDoS · Cloud Cost

Kentik Network Observability

Analyzes high-volume NetFlow, BGP and sFlow data in real time. AI-based DDoS detection supports automatic mitigation triggers within 90 seconds of an attack starting, and cloud traffic cost analysis prevents budget overruns.

  • Real-time processing of hundreds of thousands of flow records per second
  • BGP routing visibility — detects route changes and hijacking
  • Automatic DDoS detection with RTBH·FlowSpec integration
  • Detailed AWS, Azure and GCP traffic cost analysis

Featured Outcome
ISP DDoS detection automation
DDoS detection averaged 30 minutes before Kentik. After deployment, automatic detection and mitigation trigger within 90 seconds minimized customer service impact.
Infoblox BloxOne Threat Defense DNS Visibility · Threat Detection · IPAM

Infoblox BloxOne Threat Defense

Analyzes all DNS queries to block C&C communication, data exfiltration (DNS tunneling) and access to malicious domains in real time. Combined with IPAM data, it delivers complete visibility into exactly which device accessed which domain.

  • DNS query-based threat detection — C&C, phishing, ransomware
  • DNS tunneling detection and automatic blocking
  • Per-device DNS history tracking linked to IPAM
  • API integration with security solutions (SIEM, SOAR)

Featured Outcome
Financial institution insider-threat detection
Detected early signs of ransomware infection through abnormal DNS query patterns on an internal PC — isolated before it could spread, minimizing damage.

Business Impact

The outcomes you can expect from an end-to-end observability deployment.

80%↓
Faster root-cause analysis
Unified NPM/APM analysis cuts root-cause identification from tens of minutes to just a few.
90 sec
Automatic DDoS detection
Kentik's AI-based detection triggers automatic mitigation.
10x
Faster ERP response
Overseas-site SAP ERP response improved 10x after applying SteelHead.
30%↓
Cloud cost optimization
Identifies and cuts unnecessary traffic and data-transfer costs.
NPM (Network Performance Monitoring) monitors the performance of network infrastructure (switches, routers, WAN links). APM (Application Performance Monitoring) measures application response time, error rate and user experience. For full visibility, we recommend deploying both together.
You can collect packets via SPAN (port mirroring) or install a TAP device in front of the switch. Riverbed Alluvio supports NetFlow, SPAN and packet-capture methods alike.
Yes. Both Kentik and Riverbed Alluvio ingest AWS VPC Flow Logs, Azure NSG Flow Logs and GCP Flow Logs, so cloud traffic is monitored in the same console as on-premises.
Outage detection time typically drops from tens of minutes to just a few, and root-cause analysis time is cut by 80% or more. It also commonly surfaces unnecessary bandwidth and cloud spend, translating into direct cost savings.
