VIAVI partners with Ground Control to enable maritime vessel tracking in GPS-denied environments

VIAVI Solutions has partnered with Ground Control to integrate its Secure µPNT STL-1000 receiver into RockFLEET Assured, an asset tracking and navigation solution for maritime vessels operating in GNSS-denied environments. The compact software-defined receiver delivers precise timing with holdover capability, enabling tracking and navigation in denied, degraded and disrupted space operational environments. It addresses vulnerabilities from GPS jamming and spoofing, which have become increasingly common in cyber warfare. RockFLEET Assured is a marine-grade positioning, navigation and timing solution designed to support maritime vessel navigation when GNSS signals are unavailable. The partnership aims to strengthen resilience for mission-critical operations across defence, maritime and critical infrastructure sectors by providing a trusted secondary position source beyond traditional GPS reliance.

Viavi Solutions hits 24-year high on Stifel 'buy' recommendation

Viavi Solutions climbed to a 24-year high on Tuesday, reaching $36.03 intraday before closing 6.93% higher at $35.94 per share. The surge followed a "buy" recommendation from Stifel, which maintained a $35 price target after the company showcased its AI solutions portfolio at a California conference. Viavi displayed products including 1.6T Ethernet testing, silicon photonics manufacturing and fiber inspection tools. The company introduced its INX 700 probe microscope and DCX-700 optical loss test set, which enables 24-fibre simultaneous measurement. Viavi is also participating in the RSA Conference in San Francisco from 23 to 26 March, where it has presented its Observer Threat Forensics tool designed to help organisations identify security vulnerabilities and analyse data breaches.

VIAVI launches Observer Threat Forensics with CrowdStrike for unified NetSecOps analysis

VIAVI Solutions has launched Observer Threat Forensics, a solution combining network operation management with CrowdStrike-powered threat intelligence to support converged NetSecOps teams. The platform provides retrospective analysis capabilities and unifies packet insights, flow data and log telemetry into a single dashboard. The solution addresses growing demand for convergence between network and security operations. VIAVI's State of the Network study found that 79% of 750 surveyed CIOs and CISOs wanted to move away from siloed operational models, yet only 27% have begun the transition. Observer Threat Forensics leverages existing network performance monitoring data to provide both performance insights and security threat investigation capabilities. The platform helps organisations identify vulnerabilities, analyse breaches and understand intrusion points whilst eliminating data gaps. VIAVI showcased the solution at the RSA Conference in San Francisco from 23-26 March.
