Fortinet Hits 52-Week High as AI Security Platform Demand Lifts Q2 Billings 33%

Aviatrix announced Harvest and Decrypt Protection, which it calls the first post-quantum protection that encrypts data and simultaneously governs what a compromised workload can reach, delivering crypto-agile encryption and Communication Governance as one policy in software on the network enterprises already run. The offering arrives a month before federal civilian agencies must file post-quantum migration plans on October 22, and ahead of the 2029 full quantum-readiness roadmaps published by Google and Microsoft; Amazon Web Services publishes no equivalent target. Harvest Protection comes with five free policies to start, with no trial clock and no purchase required, and is free to start for existing Aviatrix customers, with the first five policies and five nodes free with no license and no time limit. Aviatrix said its patented High-Performance Encryption engine removes the throughput trade-off that causes most enterprises to leave cloud transit unprotected, citing one Fortune 5 customer running 400 gigabits per second fully encrypted in production at line rate, and that key establishment on the control plane uses the ML-KEM standard today, with hybrid ML-KEM on the data plane a fast-follow release. The company is working with global systems integrators and security services providers and collaborating with Microsoft on the Quantum Safe program as the network traffic and Harvest Now, Decrypt Later containment solution. Aviatrix also cited deadlines including Executive Order 14412, which sets December 31, 2030, for post-quantum key establishment and December 31, 2031, for digital signatures on high-value assets, and said enterprises can begin with a free Containment Assessment that returns a provisional Blast Radius and harvest exposure read in about five minutes.

Zscaler's Security for AI bookings rose more than 50% sequentially in the fourth quarter of fiscal 2026, with AI Protect bookings crossing $100 million over the trailing 12 months.
