What is a Key Management Service?

In 2025, developers pushed 28.65 million new hardcoded secrets to public GitHub repositories, a 33.9% jump from the year before, while leaked credentials for AI services rose 81%. Each of those secrets is a password, token, or key sitting where anyone who reads the code can copy it,

Post-Quantum Migration Is a Key Management Problem

The post-quantum algorithms are ready for Q-Day, when a quantum computer becomes powerful enough to break standard public-key cryptography. NIST published its first three standards in August 2024 (ML-KEM for key encapsulation, ML-DSA and SLH-DSA for signatures) and selected HQC as a backup in

The Space Industry's 5 Billion Dollar Blind Spot

The space cybersecurity market is approaching $5 billion in 2026 and is projected to exceed $10 billion by the early 2030s. As more capital flows into the sector, established defense contractors are expanding their offerings and a growing number of startups are entering the space. Most of that investment secures
