Precision Timestamps for Financial Institutions
Why Nanosecond Timestamping is a Business Imperative – Not Just a Technical Upgrade
In financial services, time is not just money; it is evidence. Every packet crossing your network carries a story: when a trade was initiated, when an alert was triggered, when a security event occurred. If your infrastructure cannot record that story with precision, you are exposed – operationally, legally, and competitively.
Cubro’s advanced network packet brokers deliver chipset-based nanosecond timestamping – the level of precision that modern financial infrastructure demands.
The Business risk you may not see
Without verifiable timestamps, MiFID II and DORA audit requirements cannot be met, creating material compliance risk.
Millisecond-level timestamps in high-frequency environments result in multiple packets sharing the same timestamp, corrupting telemetry.
In algorithmic and high-frequency trading, timing gaps of even microseconds translate directly to execution quality and revenue.

What changes with Nanosecond Timestamping
- Regulatory Certainty. Your compliance posture strengthens immediately. MiFID II, DORA, and SEC recordkeeping regulations require accurate and verifiable timestamps for all transactions and network events. Cubro‘s 8-byte timestamping provides an immutable, hardware-generated audit trail.
- Security and Forensics. Detect anomalies at the packet level. Determine the exact moment a breach occurred, correlate events across your infrastructure, and build time-aware security models. This level of detail is not achievable with millisecond-resolution tools.
- Trading Integrity. Guaranteed micro-traceability in every trade environment. In high-frequency and algorithmic trading, every nanosecond is a competitive variable. Cubro ensures your transaction records are synchronised with precision time protocol (PTP), so your timestamps hold up under regulatory scrutiny and internal audit.
- Performance Visibility. Reduce the mean time to resolution for network incidents. Pinpoint latency, jitter, and packet loss across 100G links with a level of resolution that most monitoring tools simply cannot match. Time-aware telemetry becomes the foundation for network optimisation.
- Accurate Network Analysis.Timestamps enable precise reconstruction of network events, enabling faster troubleshooting of latency, jitter, and congestion issues. When packets are captured from multiple sources or at different speeds, timestamps ensure they are stored and analyzed in the correct chronological order.
Cubro vs. Standard Network Packet Brokers
| Capabilty | Cubro EXA Series / C32 and C48 | Standard NPBs |
|---|---|---|
| Timestamp Resolution | 1 nanosecond | Milliseconds to microseconds |
| Time Sync Options | NTP, PTP | Usually NTP only |
| Timestamp Format | 8-byte IEEE-based | 6-byte (custom/limited) |
| Packet-Level Accuracy | Every packet, every port | Inconsistent |
| Regulatory Audit Trail | Yes – immutable, verifiable | Partial or unavailable |
| High-Speed Support | 100G ready | Performance-limited |
Extended Capabilities: C32 & C48 Aggregators
Cubro’s timestamping capability extends beyond the high-speed EXA series. The C32 and C48 Aggregators bring the same nanosecond precision to a wider range of deployment scenarios, with four flexible timestamp formats designed to work with the tools your teams already use.
Adds a new header to each packet. Allows your forensic and analytics tools a precise reconstruction of network events, enabling faster troubleshooting of latency, jitter, and congestion issues without losing any MAC address information – compatible with Wireshark via Cubro’s lua file.
Timestamp is written into or after the MAC address fields of the original packet. No additional bytes are added, so packet size remains unchanged – important in environments where packet size affects forwarding behaviour.
Designed for direct compatibility with leading network analysis platforms. Overwrites source MAC address and 2 bytes of destination MAC address with timestamp data – no packet overhead, no loopback port required. Validated with industry-standard latency analysis tools used across financial services.
Every packet can carry both a precise nanosecond timestamp and a unique VLAN ID identifying its ingress port – in a single pass, without any loopback. This means your analysis tools know not just when a packet arrived, but exactly where it entered the network.
Why four formats matter: Different analysis tools expect timestamps in different positions within the packet. Rather than forcing you to change your tooling, Cubro adapts to your existing environment. Whether your infrastructure uses standard network analysis platforms or custom capture solutions, one of the four formats will integrate without modification.
Proven in the field: A leading Nordic Bank
A leading Nordic bank, operating across multiple markets with stringent regulatory obligations, came to Cubro with a problem that many financial institutions share but few have solved: their network timestamping was inconsistent.
The Problem
Different monitoring tools across the bank’s infrastructure used different timestamping standards and resolutions. The result was a patchwork of time references, some at the millisecond level, some inconsistently synced, creating discrepancies in transaction records, security logs, and performance data. For a bank with compliance obligations across multiple jurisdictions, this was not a minor technical issue. It was an audit risk.
The Approach: Proof of Concept First
Rather than asking the bank to commit immediately, Cubro proposed a Proof of Concept. The bank’s network team could evaluated the capabilities of the Network Packet Broker directly within their own infrastructure, with full technical support from Cubro throughout. This approach allowed the bank to validate performance, integration compatibility, and timestamp accuracy against their own traffic, on their own terms.
The Outcome
Cubro delivered centralised, hardware-based nanosecond timestamping across all network traffic – providing a single, uniform time reference for every packet, for every monitoring tool. The bank’s security, forensic, performance, and compliance applications all drew from the same consistent source. Timestamping discrepancies were eliminated. The audit trail became dependable.
Key takeaway: The bank did not need to replace existing monitoring tools. Cubro’s Network Packet Broker sat centrally in the infrastructure, normalising timestamps before traffic reached any downstream application. One deployment resolved inconsistencies across the entire monitoring stack.
Why Financial Institutions trust Cubro
Cubro has spent over two decades developing network visibility technology to meet the demanding requirements of financial services, telecommunications, and critical infrastructure. Our solutions are built and supported in Europe, giving our customers direct access to engineering expertise and a team that understands the regulatory environment they operate.
We do not believe in one-size-fits-all. Our timestamping solution offers four different time stamp formats to make sure monitoring systems are able to ingest time stamps without modifications.
