WAN Solution
High-Fidelity WAN & Application Performance Analytics
Netis enables deep observability of critical WAN links, including branch offices, external partners, and inter-site connections, through packet intelligence and flow-based data.
Agentless by design. Agentless by design: Passive, out-of-band traffic mirroring makes latency visible without installing agents or changing production systems.
Problems We Solve
Where WAN Performance Breaks
Network complexity
Limited visibility across branch, remote office, and partner WAN links makes it hard to pinpoint where performance degrades.
Unpredictable performance
Diagnosing link degradation, SD-WAN tunnel issues, and last-mile instability is slow without reliable measurement and evidence.
Accountability & planning gaps
Without actionable data, teams struggle with capacity planning and holding service providers accountable for SLA issues.
Outcomes that Matter
Rapid isolation
Isolate issues down to a specific branch, ISP path, tunnel, or physical link.
Faster RCA with evidence
Accelerate root cause analysis using packet-level and transaction-level evidence (not guesswork).
Better experience & planning
Reduce jitter/loss impact, stabilize routing decisions, and plan upgrades with confidence.
What You Can See
What You Can See and Prove
Critical-Link Monitoring
High-resolution analytics on the WAN links that matter most: Branch / External Partner / Core Inter-Site.
Dual Mode Coverage
Deep packet capture for L7 and transaction observability. Flow-based remote monitoring (IPFIX / NetFlow / NetStream) for economical coverage across more branch sites.
Application Observability
L7 metrics that reflect real application behavior across WAN connections—beyond bandwidth charts.
SD-WAN Overlay and Underlay Correlation
Map tunnels to physical circuits to track whether the issue is a tunnel, a circuit, or an upstream path.
Detect Experience-Breakers Early
Detect tunnel flaps, jitter spikes, asymmetric routing, and ISP congestion signals.
Intelligent Evidence Extraction (PCAP)
Intelligent PCAP extraction linked to a metric/host/tunnel/app/branch to speed escalation and decisions.
Core Capabilities
- Packet-level WAN path analytics and latency decomposition.
- Microburst, jitter, and retransmission detection across WAN hops.
- Carrier/ISP link-level comparison and SLA tracking.
- End-to-end transaction path mapping across WAN, DC, and cloud.
- Historical replay for incident investigation and audit.
- RESTful API integration with ITSM/SIEM platforms.
How Teams Use It
Real-World Scenarios
Branch office WAN degradation
Users in a branch office experienced slow access to SaaS applications. Netis detected abnormal jitter and intermittent loss on the branch's last-mile circuit, confirming ISP-side degradation.
The team escalated with precise evidence; the provider fixed the line and SaaS performance recovered without further complaints.
SD-WAN tunnel instability
IPSec/SD-WAN tunnels between HQ and a partner site flapped intermittently. Netis correlated underlay packet loss with tunnel resets and identified the problematic upstream hop.
Routing/policy selection was updated; tunnels stabilized, and session drops decreased.
Inter-site application latency
Peak-period traffic between two sites slowed. Netis revealed queueing and micro-congestion on a specific backbone circuit.
Capacity upgrade planning plus short-term traffic engineering improved responsiveness immediately.
