JPMorgan’s CISO letter to suppliers

A company at the centre of many suppliers, four flagged.

We’re building AI skyscrapers on SaaS sand. And JPMorgan just handed us the blueprint for collapse. When JPMorgan’s CISO pens an open letter calling out entire supply chains for being fundamentally insecure — you pay attention. Because when the biggest bank on Wall Street publicly warns that AI is magnifying blind spots, it’s no longer just a security team problem. It’s a board-level existential risk. Here’s the punchline we’ve been telling our clients behind closed doors: You didn’t get breached. You auto-integrated into a breach waiting to happen. Unpacking JPMorgan’s diagnosis: → SaaS is now your attack surface — and you’re not even tracking it. → APIs and AI agents are granted keys to the kingdom via “easy integrations.” → Most vendors still treat security like a checkbox, not a prerequisite. → Opaque dependencies mean you have no idea what your AI tools can see. → Annual audits? Cute. We need continuous proof of control effectiveness. This is why we exist. As a fractional CISO firm, we help boards and growth-stage leaders navigate the invisible risks introduced by AI and SaaS. Because today’s risks are buried not in your code — but in your connections. Our priority right now? ✅ Map and assess your AI/SaaS integration exposure ✅ Redesign security governance to be real-time and verifiable ✅ Run breach simulations that actually reflect modern toolchains ✅ Reset vendor expectations with enforceable security standards JPMorgan’s CISO just gave the world a wake-up call. ⏰Don’t hit snooze. Time to fix your foundation — before your AI ambitions outgrow your risk capacity.
