Our devices in overview

Allegro 200

The Allegro 200 is our entry-level appliance. It is not much larger than a smartphone and weighs only 260 g, an ultra-portable solution particulary suitable for smaller organizations. The Allegro 200 can analyze the data traffic for up to 50 PCs or servers and data rates of up to 1 GBit/s full duplex immediately after commissioning inline or at the mirror port.

The Allegro 200 is available as a portable version with 2 GB in-memory database.

2 x 1 GBit/s ports enable a highly accurate analysis of a link inline or at a TAP or for up top two mirror ports.

Management is handled via an incorporated USB Ethernet adapter or USB WLAN adapter.

An external hard disk or SSD can be connected via USB 3 as a packet ring buffer and enables continuous recording of up to 2 GBit/s in the LAN.

Allegro 1000 Series

Allegro 1000 series appliances are cost-efficient entry-level versions for 1 GBit/s to 10 GBit/s analysis of up to 10,000 servers. These network tools provide a highly accurate analysis of an entire location. Depending on the existing network traffic, this is enough for a complete analysis of all data from the several previous days which can be retrieved in real-time from the in-memory database. All Allegro 1000 appliances can be expanded with SFP+ ports, packet ring buffers and additional in-memory database storage. The SFP+ ports allow an analysis of both short- and long-range fiber connections. The Allegro 1000 series can also be transparently installed inline in Spanning Tree or LACP trunks to analyze port extension errors.

The portable Allegro 1000 and the Allegro 1200 are available as 1U rack units. Both appliances have the same processing power. The Allegro 1000 is designed as a portable system and therefore has only one expansion slot. The Allegro 1200 on the other hand offers two slots, one for extended network ports and the other for a large internal hard disk. Both appliances can also be equipped with a high-speed NVMe SSD.


The basic versions of the Allegro 1000 and 1200 have 2 x SFP+ for 1 G and 10 G SFP modules, 5 x 1G-BaseT for analysis and 1 x 1G-Base-T as a management port. In addition, there are expansion cards for up to 4 x SFP+ ports, 2 x 10G-Base-T ports, 4 x 1G-Base-T ports, 2 x SFP28, 2 x QSFP28 or 2 x SFP+ with GPS connections for exact time stamps in the nanosecond range. The basic version is equipped with a 16 GB in-memory database. This can be expanded to 64 GB or 128 GB respectively.

Internal hard disks or NVMe SSD can be installed as ring buffers. With the NVMe SSD, a continous write speed of up to 10 GBit/s is possible. As with the Allegro 200, external USB3 HDDs or SSDs can also be connected.

Historical data traffic stored in the ring buffer can be extracted in Pcap format and further processed with Wireshark (for example).

Allegro 3000 Series

Allegro 3000 series appliances are suitable for ISPs, large data centers and large enterprise networks for link analysis on nodes with a load exceeding 10 GBit/s.

The 3000 series differs from the 1000 series by a 4 x packet processing rate. This enables real-time and historical analysis for up to 40 GBit/s traffic. With optional 25 G (2 x SFP28) and 40 G / 100 G (2 x QSFP28) expansions, the Allegro 3000 series is the ideal analysis appliance for networks with 25, 40 or 100 G ports.

Analogous to the 1000 series, the Allegro 3000 series is available as a 1U device (Allegro 3200) and as a portable version (Allegro 3000) with the same connections as the 1000 series. All expansion options of the 1000 series are also available for the Allegro 3000 and 3200.

The Allegro 3000 series incorporates a 64 GB in-memory database for large network analysis in the basic version. This is expandable to 128 GB.

As with the Allegro 1000 series, internal hard disk, NVMe SSD or external USB 3 HDD / SSD can be used as ring buffers.

Historical data traffic stored in the ring buffer can be extracted immediately in Pcap format and further processed with Wireshark (for example).

Allegro 3500 / 5500 Series

The 3500 / 5500 series of Allegro Network Multimeters are optimized for analysis, monitoring, verification and troubleshooting of 1 GBit/s to 100 GBit/s network connections. The systems are designed for extremely high recording, analysis and storage rates and provide retroactive verification of up to 800,000 IP addresses and up to 256 million connections.

Allegro Network Multimeter appliances are ideal for use in large data centers, core networks and ISP infrastructures. The Allegro 3500 / 5500 is equipped with a back-in-time function and enables precise selection of the recorded information. These data can be extracted as Pcaps via a browser download with a single click. In addition, selected data can be individually imported back into the network to recreate specific events or security incidents.

The 3500 / 5500 series has several extensions for additional connections and memory options. The dual QSFP28 option allows up to 60 GBit/s of real-time traffic to be checked in 100 GBit/s environments. Alternatively, the number of ports can be increased up to 20, selectable from 1, 2.5, 5, 10, 25 or 40 GB Ethernet Cu / SFP+ / QSFP ports. The memory size for processing historical data in the in-memory database is 96 GB or 192 GB in the basic version and can be expanded up to 1536 GB. The ring buffer for recording the traffic of a link or the selected data traffic enables the extraction of historical packets. The ring buffer can be dynamically expanded up to 360 TB.
