JetStream Security

JetStream Security governs AI in production with visibility, identity accountability, runtime enforcement, drift detection, and cost control.

AI is ready. Trust isn’t.

Today, we’re making something official.

JetStream Security has raised $34M, led by @Redpoint Ventures with participation from the @CrowdStrike Falcon Fund and industry leaders, to solve a critical enterprise problem: how to trust the AI systems already operating in production.

AI now calls APIs, accesses data, inherits permissions, and consumes budget. But when boards ask simple questions like where it is running, what it is doing, who owns it, and what it costs, many organizations cannot answer with confidence.

The gap isn’t model performance. It’s governance.

AI has moved from experimentation to infrastructure. It acts under credentials and makes decisions with real financial and operational impact. Without visibility and accountability at runtime, trust breaks down. When trust breaks down, adoption slows.

We built JetStream around a simple belief:

Governance enables trust. Trust unlocks advantage.

Governance is the control layer that makes AI visible, attributable, and defensible in production.

Our founding team—Raj Rajamani (CEO), Jared Phipps (COO), Jatheen Anand (CTO), and Venu Vissamsetty (Chief Architect)—has led product, engineering, and go-to-market at some of the most influential security companies of the last decade. We’ve built platforms that protect the world’s largest enterprises, scaled organizations through hypergrowth, and navigated the security challenges that emerge with every new computing paradigm.

AI is ready for takeoff.

Now it needs governance-grade trust.

In his latest piece, JetStream CEO and co-founder Raj Rajamani argues that AI spend needs the same discipline boards already apply to capital: allocated deliberately, protected, and tied to someone accountable for the return.

One developer left agents running over a weekend and came back to more than $45,000 in token charges nobody had approved. Reporting explains that bill. Control would have stopped it.

Reporting tells you what already happened. Control lets you decide what happens next.

A read-only file tool is safe. A web-fetch tool is safe. Together, they’re an exfiltration path.

No per-server review will catch it. Pratik Roychowdhury explains why MCP needs more governance than most teams expect: https://t.co/r9sizLG6Ku

[JetStream Security @jetstream_sec]

Agents are already running in your environment. Some you approved. Some you have never seen. Governing them comes down to five things, which we call the AI Trust Gaps:

You can't control what you can't see.
You can't approve what you can't describe.
You can't enforce what you can't verify.
You can't trust what you can't attribute.
You can't scale what you can't afford.

On November 10th at 1pm PT, our solutions engineers will show you how to close all five in a live walkthrough of the JetStream SAIG Platform™. The JetStream Pre-Flight Demonstration covers:

1.) The five AI Trust Gaps, and why enterprise AI stalls before production
2.) A live product demo
3.) A first look at everything released since the last session, including what is not on our website yet

Your questions, answered live. Come hear what your peers are asking, and leave knowing whether JetStream meets your needs.

Nothing else matters… when you’re with the right team. 🤘

The JetStream team traded dashboards for devil horns at Metallica at the Sphere in Las Vegas. Hearing the crowd, and our team, singing as one was a reminder of why we do this: great things happen when people come together.

Security is a team sport. The best moments aren’t always in the boardroom. Sometimes they’re a few rows up, arms in the air, next to the people you trust to build something better.

A huge thank you to our partners at Vega for joining us and helping make this a night to remember, and to CISO Experiences for hosting an unforgettable experience.

To the JetStream crew: thanks for bringing the energy. 🔥

Keep a human in the loop" is the right answer. It is also where most security teams are about to get it wrong.

Joe Poyner makes the case in his latest piece. An approval queue a person clears 400 times a day is not a control. It is automation with a signature on it.

The research backs him up. Run a monitoring task with automation and people miss 41% of the events it never flags (Skitka, Mosier, and Burdick, 1999). Take the automation away and the same people miss 3%.

So the loop has to be built to survive human attention, not assume it. Approvals rare enough to take seriously. Rich enough in evidence to verify independently, the actual diff and the actual target. Signed with a name that owns the outcome.

Aloha from Maui! 🌺

Last week, the JetStream team joined the legal tech community at the 16th Annual EDI Leadership Summit at the Westin Maui Resort & Spa, Ka’anapali. This year’s Summit marked a special milestone: the 20th anniversary of the Electronic Discovery Institute.

For two decades, EDI has brought together a close-knit community of legal professionals known for their expertise, curiosity and collaboration. Seeing that on display, from hands-on demos to ocean-view conversations, was a highlight of our year.

A big shout-out to our own Patrick E. Zeller and Joe Poynter for representing JetStream and for guiding some great conversations all week.

Thank you to the EDI team and everyone who made the 20th anniversary such a memorable celebration of the relationships, insights and innovations shaping legal technology. Here’s to the next 20! 🤙

A marketer with no development background woke up with a problem her team had been stuck on for a year. She described it to an AI tool, and it wrote her an application. It worked.

No IT review. No governance. No bad intent.

Keith Weisman, our Head of Forward Deployed Engineering, uses that story on The Data Diva Talks Privacy with Debbie Reynolds to explain why shadow AI spreads the way it does. People take the path of least resistance, and AI made that path very short.

The gap is not enthusiasm, it is visibility. Keith walks Debbie through the five AI trust gaps: visibility, design control, drift, agentic identity, and financial accountability. The thread running through all five is that an agent inherits a human's access without inheriting anything that makes a human careful.

His framing for what governance is actually for: build the environment that lets people move fast without putting confidential data somewhere it cannot be retrieved.

An AI kill switch only matters if you can actually reach it.

The labs claim they can contain their models, but their incident reports show otherwise. Regulators are still debating rules, and none of them can pull the plug inside your environment.

So if an agent went rogue tonight, would you see it, know who owns it, and be able to stop it?

We’re tackling that exact question in our webinar next week with JetStream's Raj Rajamani, Rusty Perry, Patrick E. Zeller, and special guest Jay Wilson of Insurity.

Most security models were built to keep threats outside the perimeter. AI arrived on the inside.

That's the reframe our General Counsel Patrick Zeller brings to The Data Diva Talks Privacy with Debbie Reynolds podcast. AI entered most enterprises through productivity suites and platform updates, before legal, privacy, or the CISO's team ever reviewed it. It now reads from the systems holding compensation data, trade secrets, and privileged communications.

Patrick sorts the risk into what goes in, what comes out, and everything adjacent. A bank has already filed an 8-K over an employee putting sensitive information into a public AI tool. Courts are issuing legal holds on AI queries. Most organizations cannot yet answer which tools are in use, who is using them, and what databases those tools can reach.

His argument is that this is workable. GDPR was workable. E-discovery was workable. Start at phase zero and find out what you actually have.

The labs say they can contain their own models. Their published incidents say otherwise. Regulation is being actively discussed, yet no rule nor regulator can pull the switch inside your environment. If an agent went rogue tonight, would you see it, know who is accountable, and be able to stop it?

Join JetStream co-founder and CEO Raj Rajamani, JetStream vCISO Rusty Perry, General Counsel Patrick Zeller, and Jay Wilson, CIO & CISO of Insurity, for an unscripted, operator-to-operator chat on what makes an AI kill switch real for enterprise. https://t.co/Lhv0GNpeZP

AI notetakers are in every meeting. Are they in your risk assessment?

A federal court recently let wiretap and privacy claims move forward against Otter AI, the maker of a popular AI notetaker. JetStream General Counsel Patrick E. Zeller explains what that means for companies that use these tools: consent, discovery exposure, and privilege risk. He also lays out practical controls to put in place now.
