Full Packet CaptureThe foundation under every solution

Capture everything.
Drop nothing.

NIKSUN's packet capture is the most powerful in the industry. Run 100 Gbps with ease and cluster to multi-Tbps — without losing a single packet — in a footprint as small as one-tenth of other solutions. Complete data means zero blind spots for everything built on top.

Why it leads the industry

Lossless. Massive scale. Tiny footprint.

🎯

Zero packet loss

Every packet captured, timestamped, and indexed to the NKW with no drops — even at line rate. No loss means no blind spots in detection, forensics, or performance.

📈

100G to multi-Tbps

Handle 100 Gbps links comfortably and cluster appliances to reach multi-Tbps of sustained, line-rate capture as you grow.

🪶

One-tenth the footprint

Purpose-built hardware and NikOS deliver this scale in as little as 1/10 the space — with up to 60% less power and 80% less rack space.

No sampling

Search Top-N and Bottom-N.

上位Nおよび下位Nを検索。

Because NIKSUN captures the entire packet and analyzes with no sampling, you aren't limited to the loudest talkers. You can query Bottom-N too — the rare, quiet events sampling tools average away. That's what surfaces intermittent, hard-to-reproduce performance issues and low-and-slow attacks built to stay under the threshold.

Capture economics

Keep everything — without the storage bill.

Total recall doesn't have to mean total cost. Industry-leading compression shrinks NIKSUN's footprint below any competitor — and from every packet we generate thousands of rich metadata fields. Retention is fully configurable: keep packets and metadata for exactly as long as each deserves — independently, with no theoretical limit to either.

Configurable retention, built in

Total recall, made affordable.

  • Industry-leading compression — a smaller footprint than any competitor
  • Thousands of metadata fields generated from every packet, automatically
  • Configure packet and metadata retention independently — with no theoretical limit to either
  • Up to 60% less power and 80% less rack space than other solutions
Sensitive data, handled

Capture everything — expose only what's allowed.

Capturing every packet means capturing sensitive data too. NIKSUN masks it before anyone sees it, gates access by role — and the zero-loss guarantee isn't marketing.

🛡️

Built-in data masking

Mask sensitive fields — PII, PCI, PHI — automatically, so analysts get the evidence they need without ever seeing what they shouldn't.

🔐

Policy-gated access

Role-based access with end-to-end encryption in motion and at rest — and fully air-gap capable for the most restricted environments.

🎯

Zero loss, proven

Not a single dropped packet — validated across demanding enterprise deployments and the most rigorous government and defense testing.

How NIKSUN delivers it

Purpose-built capture, end to end.

NetBlackBox Pro
Powered by

NetBlackBox Pro on NIKSUN appliances

NIKSUN engineers the full stack — NikOS, custom hardware, and the NIKSUN Knowledge Warehouse — for line-rate capture to disk. NetBlackBox Pro captures, timestamps, and indexes every packet with zero loss, scaling from 20 Gbps to multi-Tbps while consuming 60% less power and 80% less rack space than any other industry solution.

How it works

From the wire to total recall.

Capture

Every packet off the wire at line rate, with zero loss.

Timestamp

Precision timestamping and indexing as packets arrive.

Store

Written to the NKW at petabyte scale for long retention.

Serve

Ultra-fast search and replay back-in-time, on demand.

One capture, every function

The same packets power your whole stack.

Capture once, losslessly — then run detection, forensics, performance, and observability on the very same data. No duplicate collection, no gaps between tools.

The ground truth for everything

No data loss means no blind spots.

Sampling and lossy SPAN force every tool downstream to guess. NIKSUN's lossless capture gives detection, forensics, performance, and Maya AI the same complete, replayable record — the difference between knowing and assuming.

NetTrident
When you can't capture 24/7

Remote packet capture — live, triggered, or on demand.

For sites without a full-time capture appliance, NetTrident pulls packets back and stores them in NetBin — so you still get ground-truth packets where you need them, when you need them. Decrypt those captures with built-in decryption, TLS 1.3 included.

Know the Unknown

Capture every packet.
Miss nothing.
