Financial latency measurement

Our solutions deliver data to applications that make delays visible by capturing all transactions and measuring the exact time of each trading event up to the nanosecond. This enables financial institutions to guarantee optimal performance and transparency of their trading infrastructure.

Fraud detection and compliance management

Our solutions deliver data to applications that ensure compliance with regulations, protect trading information, and reduce the risk of confidential information leaks. This enables stock exchanges to provide a seamless, secure trading experience for their customers.

Infrastructure management and security

Our solutions deliver data to applications that enable infrastructure network managers to optimize performance of power transmission, water distribution, transportation, healthcare, and other complex networks. The insight delivered helps sustain the reliable functioning of these vital networks and creates the visibility needed to protect them.

Cyber defense

Our solutions deliver data to applications that help governments see all data running through their networks. Recognizing malicious packages and suspicious patterns allows governments to take preemptive measures to stop criminals before or during an attack, safeguarding sensitive government information as well as the personal data of citizens.

Security data collection

In order to protect networks from the most advanced cyber threats, our solutions deliver data to security applications such as:

  • Intrusion Detection Systems / Intrusion Prevention Systems (IDS/IPS)
  • Unified Threat Management (UTM)
  • Security Information and Event Management (SIEM)
  • Data Loss Prevention (DLP)
  • Advanced Persistent Threats (ATP)

Security data collection systems make it possible to discover and contain threats faster based on real-time data from critical network links.

Network and content security

Our solutions deliver data to network appliances such as Intrusion Prevention Systems (IPS) that can see every detail within the networks they are protecting. They can stop attacks, protect against data leaks, and provide 100% accurate records of everything that happened.
