Across AI, digital currencies, and quantum.
Grey Orbits is a Cybersecurity and Risk Advisory practice, based in Singapore, with capability to deliver globally.
Domain expertise spans the design, architecture, and implementation of cybersecurity and risk programmes at institutional scale.
That expertise translates to counsel for boards, investors, and operating executives at the convergence of three disruptive frontiers: artificial intelligence, digital currencies (blockchain, cryptocurrencies, DeFi, and tokenisation), and post-quantum cryptography. These are the domains shaping the next decade of enterprise risk, regulatory expectation, and competitive advantage.
Engage Grey Orbits before your risk becomes the headline or the regulatory inquiry. The practice spans agentic AI governance, post-quantum cryptographic migration, credential and secrets security, and the tokenisation of real-world assets, often well before these matters formally reach the board agenda.
The name GREY ORBITS and emblem capture the practice. Three orbits, Technology, Cyber, Risk, protecting what matters most.
Investment targets and strategic partners assessed across cybersecurity resilience, AI governance maturity, and cryptographic readiness. Investors receive a clear verdict, not a checklist.
Drawing on two decades of practice across institutional and venture-stage technology environments.
Founders supported in cybersecurity, AI governance, and digital infrastructure. Engagement shapes early risk posture, regulatory positioning, investor narrative, and route to market.
Drawing on experience leading cyber across approximately twenty fintech ventures at SC Ventures.
Board papers, executive briefings, and enterprise risk frameworks across AI adoption, post-quantum cryptography migration, and digital asset strategy. Technical complexity translated into decisions boards and management can endorse and defend.
Drawing on practitioner experience as CISO and the author of three proprietary frameworks in AI governance, cybersecurity, and cyber insurance.
Workshops, masterclasses, and immersion programmes for boards and senior leadership across AI Governance, Cybersecurity, Digital Currencies, and Quantum Readiness. Sessions calibrated to the audience.
Drawing on faculty experience at Singapore Management University.


Grey Orbits was founded by Viren Mantri, who leads every client engagement personally. A Singapore citizen with more than three decades across technology, cybersecurity, and risk, he has held senior roles at Standard Chartered Bank, SC Ventures, McAfee, UBS, and KPMG, with earlier development work at Citibank in India and the UAE.
As Chief Information Security Officer at SC Ventures, the venture-building platform of Standard Chartered Bank, he led cybersecurity across twenty fintech ventures in digital banking, supply chains, cryptocurrency, and tokenisation.
Prior to SC Ventures, his long tenure at Standard Chartered covered cyber architecture, design, operations, governance, risk and compliance. Earlier, he led Strategic Security Services at McAfee across Asia, ran global security monitoring at UBS, and supervised risk consulting at KPMG across banking, telecommunications, healthcare, and government. His work has remained anchored in regulated financial services, with regulatory engagement across jurisdictions and a record of authoring board papers and executive briefings.
He founded Grey Orbits years earlier, and has delivered international engagements across Japan, Switzerland, the United Kingdom, and Singapore.
At Singapore Management University Executive Development, he designs and delivers programmes for senior executives on Blockchain, Digital Currencies and Tokenisation, AI Governance, Cybersecurity, and Quantum Readiness.
He is the author of three proprietary frameworks: the PETALS™ Framework for AI Governance, whose name is registered as a trademark with IPOS; the Cybersecurity Model for Startups; and the Framework for Cyber Insurance. He writes on the convergence of AI, digital currencies, and quantum disruption.
Viren holds a Master of Technology in Artificial Intelligence Systems (formerly Knowledge Engineering) from NUS, an MBA from Quantic School of Business and Technology (US), and a Bachelor of Science from the University of Mumbai (India). He is a certified AI Governance Professional, has completed Full Stack Development with AI at NUS and the Blockchain and Smart Contract Security programme at SANS.
A practical structure for cross-functional teams to avoid pitfalls in artificial intelligence initiatives. Purpose at the centre, with Effort, Tools, Assembly, Leverage, and Secure radiating outward like the petals of a hibiscus.
Nine operational areas for building cyber resilience from day one of incubation. A practitioner methodology applied across fintech ventures, calibrated to a startup's stage of maturity, capital position, and regulatory exposure.
Five critical factors that combine to determine cyber risk and the insurance premium it should command. A structured approach to underwriting that aligns insurance product design with cybersecurity outcomes.

Anthropic asked its AI to "take a real stab" at the Riemann hypothesis, a 167-year-old mathematical mystery with a million-dollar prize. Claude did not win the prize. What it did do is push a stubborn 41.6% floor to 67.2% on a related problem, formally verified, and praised by Oxford’s James Maynard as "a genuinely interesting mathematical contribution." Then a small experiment of my own: five leading AI models given a maths puzzle that hides a visual joke. Only two spotted it. A story about two corners of intelligence, and the humility and scepticism they demand.

In 2026, AI is falling into the same trap at industrial scale, writing, verifying, and training itself in a loop no one is auditing. Watermarking is a first step, not a fix. By 2030, a child asking “is this true?” may get a fluent, confident answer with no human at its root. Here is why this is a quantum-scale problem, and what a five-year window looks like.

Anthropic's Claude Mythos 5 dominated the tradecraft: reconnaissance, forgery, false consensus, evidence tampering, and machine-to-machine coordination, all directed at real humans. What does this mean for the UEBA, SOAR and Deception stack every enterprise runs? And what does a resilient security architecture look like from here?
