In legacy environments, monitoring was a simple affair. Today, with the proliferation of encrypted traffic (TLS/SSL), virtualization, and east-west traffic flows within data centers, the network has become opaque. Traditional monitoring tools—IDS/IPS, APMs, and SIEMs—are often blinded by the sheer volume of data or the encryption protecting it.
A government agency needs to monitor a suspect’s social media activity across multiple ISPs. They deploy Cubro aggregators at IXPs (Internet Exchange Points). The Cubro filters traffic based on the suspect’s IMSI (SIM card number) across 10G links, removing 99.9% of irrelevant traffic before feeding it into deep packet inspection tools.
By offering flexible, high-performance hardware that turns raw data into actionable intelligence, Cubro empowers enterprises to move from a reactive posture—fighting fires as they happen—to a proactive stance, where the health of the network is continuously monitored, optimized, and secured. In the crowded marketplace of network infrastructure, Cubro remains the quiet professional, ensuring that the lights stay on and the blind spots are eliminated. cubro network
Perhaps Cubro’s most critical contribution to modern network security is its approach to .
Founded in Austria, Cubro began its journey not as a manufacturer of blinking boxes, but as a provider of telecom signaling probes. Unlike general IT vendors, Cubro’s engineering DNA was steeped in the rigorous standards of SS7, SIGTRAN, and early LTE protocols. This telecom heritage is critical to understanding the company’s evolution. In the early 2010s, as network speeds transitioned from 1GbE to 10GbE and 40GbE, monitoring tools (IDS/IPS, NPM tools) began to fail. They were dropping packets because they could not handle line-rate traffic. In legacy environments, monitoring was a simple affair
Cubro Network's solutions are used in a range of use cases, including:
Cubro’s SSL/TLS Visibility solutions sit in-line or out-of-band, decrypting traffic for inspection by security tools, and then re-encrypting it for delivery. This effectively "unmasks" hidden threats, turning a blind spot into a monitored highway, without compromising the end-user experience. A government agency needs to monitor a suspect’s
A European MNO launches 5G SA (Standalone). Their security stack (IDS) cannot parse 5G's HTTP/2-based signalling (NAS). They deploy Cubro XG nodes at the N3 and N6 interfaces. Cubro decodes the PFCP sessions, reassembles the user plane, and exports metadata to the SIEM. This allows the operator to detect a botnet on the 5G network that traditional firewalls missed because the traffic was encrypted inside a GTP tunnel.
Cubro Network is a network visibility and security solutions provider that offers a range of products and services to help organizations monitor, analyze, and secure their network traffic. The company was founded in 2009 and is headquartered in San Jose, California.
