Netrafix Network Monitoring and Traffic Security Family

Four modules, four questions of network operations: How much? What's happening? Stop it. Prove it. The Netrafix family brings together measurement and billing (Core), per-second attack detection (Probe), edge filtering (Filter) and a sealed, law-5651-compliant archive (Archive) under one roof. There is no mandatory order; each module can be deployed on its own.

Netrafix

No Sampling

Flow records are based on every packet on the line, not sampled (like 1/1000) counts. Small but dangerous attacks don't get lost in the noise.

Measurement Separate from Action

The component that detects is not the component that cuts traffic. A false detection cannot cause an outage on its own.

Gradual Rollout

The four modules don't have to be bought as one package; each works on its own and can be added onto existing infrastructure step by step.

Four Questions, Four Modules

Each module answers a different question of network operations

Core: How much?

Measurement, billing and capacity planning.

Probe: What's happening?

Per-second traffic analysis and attack detection.

Filter: Stop it.

Filtering of incoming traffic at the edge.

Archive: Prove it.

Law-5651-compliant, sealed record archive.

Netrafix Core

Measurement · Billing · Capacity
Measures every device and every line from one place; the number that becomes an invoice or a capacity decision comes from here.

Multi-Source Collection

Device and interface counters via SNMP polling; sFlow, NetFlow and IPFIX flow records; all merged into a single time series (ClickHouse).

Billing-Ready Measurement

Traffic volume per interface and customer; one consistent source for commitment-overage and billing-period calculations.

Capacity Planning

Line utilization trends and burst analysis; shows with data when investment is needed.

Device Inventory

Monitored devices, interfaces and their status in one list; automatic discovery when a device is added.

Web Interface and API

A panel for the operations team; a documented (OpenAPI/Swagger) REST API for integration.

Netrafix Probe

Per-Second Analysis · Attack Detection
It listens to the fiber itself. It doesn't report the attack minutes later; it tells you the second it starts.

Passive TAP Listening

Connects to the backbone with a passive optical TAP: never in the traffic path, adds no latency, and the line is unaffected even if it fails.

One-Second Resolution

Traffic and attack graphs at one-second granularity; sudden bursts invisible in per-minute averages become visible.

Attack Pattern Detection

Carpet bomb, port scan, reflection/amplification, prefix sweep, SYN and UDP flood; classified by pattern.

Names the Victim and the Vector

The alarm reports the target IP, prefix, customer, attack type and attacker ASN together; ready input for mitigation.

Routing Awareness

Knows your own prefixes, customer prefixes and transit/peering roles; ties the alarm to the right owner.

Law-5651-Compliant 1:1 Records

Records every connection individually; no sampling, no gaps. It is the input of the Archive module.

Netrafix Filter

Incoming Traffic Filtering at the Edge
Pulls the single IP under attack into the scrubbing pool; the rest of the network feels nothing.

Per-Address Intervention

Not the customer's whole block; only the address with a rule is announced as specifically as possible (down to /32); neighboring customers are unaffected.

Stateless L3/L4 Rules

Rules by protocol, port and address; keeping no state table, it has no resource to exhaust under attack.

Domain Blocking

One rule; the engine inspects the right field per protocol; Host for plain HTTP, SNI for TLS, QNAME for DNS.

Automatic RTBH Escalation

If the attack exceeds a node's capacity, instead of forcing scrubbing the address is blackholed upstream; the decision is automatic.

Horizontal Scale and Redundancy

Each prefix is assigned a primary node with a standby ready; if a node fails, BGP takeover happens within seconds.

Out of scope: TLS ECH, DoH/DoT/DoQ and queries sent to external resolvers (e.g. 8.8.8.8) are outside the coverage of domain rules.

Netrafix Archive

Law-5651-Compliant Record Archive
Keeping the record is not enough; you must be able to prove in court that it was never altered.

Subscriber Matching

From public IP and port, resolves CGNAT and reaches the subscriber via RADIUS session records; with the record valid at event time.

Qualified Timestamp

Sealing with an RFC 3161 compliant timestamp authority: an independent authority certifies the file existed at that date with that content.

Immutable Storage

WORM directory layout, SHA-256 digests, manifest and ledger; integrity verifiable at every step; the smallest change invalidates the seal.

Daily Automation

Processes the previous day every day; catches up missing days after an outage on its own, never processes the same day twice.

Efficient Format

Columnar compressed format (Parquet + zstd); low cost for data kept for years, in a queryable structure.

Frequently Asked Questions

Things people wonder about the Netrafix family.

Yes. There is no mandatory order among the four modules; each can be deployed on its own and added gradually onto existing infrastructure.

Classic flow records are often based on sampled counts like 1/1000. Netrafix processes every packet on the line; small but dangerous attacks don't get lost in sampling noise.

No. Probe connects via a passive optical TAP: it is not an active device, never sits in the traffic path, adds no latency; even if the server shuts down completely, the line is unaffected.

No. Only the address with a rule is routed to the scrubbing pool, as specifically as possible (down to /32); other customers in the same block keep flowing normally. If capacity is exceeded, the address is automatically escalated to RTBH.

Probe's 1:1 access records are matched to subscriber identity daily, written to an immutable file and sealed with an RFC 3161 qualified timestamp. The smallest later change invalidates the seal; making the record legally defensible.
