SecureSync® Time Server
The SecureSync 2400 is a reliable and modular GNSS / GPS time server. It can output both 10MHz frequency as well as pulse-per-second PPS signals and PTP. The SecureSync 2400 is designed to synchronize critical defense and commercial infrastructures that require extreme reliability and security.
Do you need to synchronize all the nodes across network? Do you need precise timestamping for a financial application? Do you need a master clock time signal for your distributed radar equipment? If you have any precision-timing requirement for your network, then the SecureSync 2400 time server is for you.
Modular Time Server
A highly modular and field‑upgradeable design, supporting dozens of option cards and multiple oscillator classes, allows SecureSync 2400 to evolve over time. Operators can adapt timing performance, interfaces, and redundancy models without replacing the entire system—reducing lifecycle risk and total cost of ownership.
The rear panel of the SecureSync offers you 6 option card slots. The flexibility with option cards enables you to add only what you need. You can synchronize your network with either NTP or PTP timing protocols. You can modify the inputs and outputs, depending on your project requirements. The SecureSync 2400 is also field-upgradeable, meaning you can swap out old option cards and slide in new ones.

Resilient Timing Architecture Against GNSS Interference
Resilient timing depends on protecting both time reference acquisition and holdover performance when GNSS signals are degraded or denied.
SecureSync 2400 Provides:
- Multi‑band, multi‑constellation GNSS reception (GPS, Galileo, QZSS, NavIC, BeiDou)
- Optional GNSS interference detection, including jamming and spoofing
- Multiple high‑performance internal oscillator options, ensuring timekeeping continuity during GNSS outages
- Support for external network and legacy references to build multi‑source, fault‑tolerant architectures
- Optional Anti-Jam Antennas, providing multi-band protection across frequencies.
This layered approach increases the complexity required to compromise timing services and aligns with resilience objectives emphasized in both EU and US critical infrastructure guidance.
These resiliency features mean that the time server can ensure that your network stays synchronized, even if there are signal interferences from jamming or spoofing.
The 8230AJ Anti-Jam Antenna is frequently purchased along with the Safran SecureSync 2400 to protect against interference signals. This is extremely important for datacenters and facilities that need to maintain uninterrupted operation.
Cybersecurity-Driven Design
SecureSync 2400 is designed with security as a foundational requirement, not an add‑on.
Core Cybersecurity Capabilities:
- VLAN support and network segmentation
- Account and access management with configurable password policies
- Authentication via LDAP, RADIUS, TACACS+
- Configurable protocol enable/disable and access control lists
- Encrypted management and services via SSL/TLS and SSH
- Security event logging and auditability
- Regular, signed firmware updates
Cryptographic Assurance:
SecureSync 2400 integrates a FIPS 140‑3 certified cryptographic module, used for all authentication and cryptographic functions.
Scaling Network Time Distribution Across Diverse Networks
Critical infrastructures increasingly span hybrid and large‑scale networks, mixing legacy systems, IP networks, high‑precision Ethernet, and geographically distributed sites. Timing architectures must scale without sacrificing accuracy or resilience.
The SecureSync® 2400 Advantage
SecureSync 2400 supports a full range of timing protocols—from NTP and PTP to White Rabbit—and scales from small protected networks to very large deployments handling millions of PTP requests per second. Optional network cards extend capacity up to multiple 1 GbE and 10 GbE ports, enabling future‑proof network timing architectures.
SecureSync 2400 delivers high‑performance, scalable network timing to support small protected networks as well as large, distributed infrastructures.
Network timing capabilities:
- NTP v2 / v3 / v4, SNTP, and NTP Anycast
- PTP v2 (IEEE 1588‑2019) with support for:
- Default profile
- Power profiles (IEEE 61850‑9‑2 / C37.238)
- Telecom profiles (G.8265.1, G.8275.2 master only)
- Enterprise and IEEE 802.1AS profiles
SecureSync is the key enabler of a highly available time and frequency synchronization distribution architecture.
It adapts to demanding infrastructure environments, with extended temperature support (-20°C to +65 °C). Time distribution to legacy systems can be achieved with a range of synchronization signals, while timing protocols (NTP, PTP) are available for synchronizing of recent systems through the networks. Configure to your needs with the ability to extend the number of option cards up to six per unit. And, alternative signals including LEO PNT are available.
Preparing For Evolving Threats And Regulatory Environments
SecureSync® 2400 also adheres to ever-evolving network regulatory compliance. Government initiatives such as the US Executive Order on Resilient Positioning, Navigation, and Timing, the European Cyber Resilience Act (CRA), are shaping requirements for availability, integrity, resilience, monitoring, and recoverability of timing infrastructures.
SecureSync 2400 directly addresses these challenges through a layered‑defense timing architecture, minimizing the probability and impact of both RF‑based and cyber‑based attacks on timing services.
