Post Quantum: Post Quantum develops cryptographic security products designed to withstand attacks from quantum computers, offering post-quantum encryption protocols, secure communications applications, and identity verification technology that protect data against both classical and quantum computing threats. The London company is among the longest-established organisations in the quantum-safe cryptography market, having focused on this security category before it gained mainstream attention following NIST post-quantum cryptography standardisation efforts.\n\nThe company raised approximately $30 million in venture funding and counts government agencies, financial institutions, and critical infrastructure operators among its clients. Post Quantum products include an encrypted communications app and a software library implementing post-quantum cryptographic primitives, as well as consulting services for organisations planning cryptographic migrations. The company has participated in NATO and government procurement processes for quantum-safe communications.\n\nPost Quantum competes with Quantinuum, IBM Quantum Safe, and PQShield in the post-quantum cryptography market, as well as larger cybersecurity vendors integrating quantum-safe features into existing product suites. The NIST finalisation of post-quantum cryptography standards in 2024 significantly accelerated enterprise and government planning for cryptographic migration, expanding the commercial opportunity for specialist vendors. The harvest now decrypt later threat model, where adversaries collect encrypted data today to decrypt once quantum computers mature, is creating compliance urgency in defence, financial services, and national security organisations. Talon Cyber Security: Talon Cyber Security built an enterprise browser security platform that delivered a Chromium-based managed browser with built-in security controls, data loss prevention, and threat protection designed for hybrid workforces accessing corporate applications from unmanaged personal and contractor devices. The Tel Aviv company addressed the gap in traditional endpoint security between corporate-managed devices covered by EDR agents and unmanaged devices used by remote workers and contractors that access the same cloud applications.\n\nThe company raised approximately $126 million in venture funding including a $100 million Series A round from investors including Lightspeed Venture Partners, Team8, and Evolution Equity Partners before being acquired by Palo Alto Networks in 2024 for approximately $625 million. The acquisition integrated Talon enterprise browser capabilities into the Palo Alto Networks Prisma SASE platform, extending SASE security controls to unmanaged device scenarios.\n\nTalon competed in the enterprise browser security market against Island, the dominant enterprise browser startup, as well as against traditional CASB and secure web gateway vendors that extend controls to unmanaged devices through agentless proxy approaches. The enterprise browser category gained significant attention as the shift to cloud applications made the browser the primary attack surface for enterprise users, and traditional endpoint security tools designed for desktop applications became insufficient for browser-based SaaS workflows. The Palo Alto Networks acquisition validated the enterprise browser security market while consolidating two of its leading competitors under a single large security vendor.

Post Quantum was founded first in 2009, giving it 12 years of additional market experience. Talon Cyber Security was founded later in 2021. In AI, even a year or two of head start can translate into significantly more training data, customer relationships, and institutional knowledge.

Post Quantum has approximately 1-50 employees, while Talon Cyber Security has approximately 100-500. A larger team often signals higher revenue or venture backing, but in AI, smaller teams are increasingly capable of building at scale.

Yes, Post Quantum and Talon Cyber Security are direct competitors — both operate in the AI Security space and likely target overlapping customer segments. This comparison is especially relevant for buyers evaluating both platforms.
