Because one without the other isn’t enough
A year ago, we asked ourselves a question that had nothing to do with product roadmaps or pipeline metrics. We asked: how do you tell the story of the people who chose the hardest, most thankless job in technology and why that story matters more right now than it ever has?
The answer is a short film called It’s Time to Defend
Today we’re releasing it, produced by Big Think https://bigthink.com/videos/ , the same team behind Andreessen Horowitz’s iconic “It’s Time to Build” video that became a rallying cry for an entire generation of builders. We didn’t partner with Big Think to make a product demo or a sizzle reel. We partnered with them to make a statement about what we believe and who we believe in.
The People Nobody Talked About
Cybercrime isn’t just growing, it’s compounding and that’s not hyperbole, it’s math. Attackers scale with automation while defenders scale with exhaustion.
Right now, a Security Operations Analyst is staring at a queue of 10,000 alerts, knowing it’s humanly impossible to get through them all. The best security talent in the world spends 80% of their time on work machines could be doing, and by the time something real surfaces, they’re too depleted to respond the way they trained to, the way they want to.
I have watched this for over 30 years. As a CISO, as a builder and as someone who has sat across the table from people who chose this profession because they wanted to protect others. I watched the industry slowly grind that purpose out of them.
That’s the structural problem and it’s the one TENEX was built to fix.
What the Door Actually Opened
When we announced our Series B, I said something that I meant more than anything I’ve ever said publicly: AI has opened the door to the best work humans have ever done.
People heard that and some of them probably thought it was a tagline. It is not. It is the thesis this entire company is built on.
The anxiety around AI is real and I understand it. Teachers watch students shortcut their thinking. Workers watch processes get automated overnight. Fear fills the vacuum when change moves fast and the benefits stay abstract. But anxiety isn’t analysis and in cybersecurity, where I’ve spent my career, the picture is becoming unmistakably clear.
AI didn’t come for the defenders’ jobs. It came for the parts of their jobs that were exhausting them.
When AI handles the volume — 100% of alerts, triaged in under a minute — humans don’t become optional, they become exceptional. They stop drowning in noise and start doing the work they actually trained for. They bring their instincts, their experience, their adversarial judgment to the threats that matter. That’s not a smaller role, that’s the largest role a defender has ever had.
Its Time To Defend tells that story. What happens when you finally give defenders real leverage. When the smartest people in cybersecurity get to do the work they were meant to do. When 100% of alerts get analyzed and not the 10% that a human team can reach before burnout takes over.
Why “It’s Time to Defend”
Cybersecurity is at the same inflection point right now. Not a disruption — an inflection. The difference matters. Disruption implies something is being broken. Inflection means the trajectory is changing and the teams who understand that change will build something the others can’t catch up to.
This industry has spent decades reacting. Managing. Coping. Pouring good people into a structure that was designed to lose slowly. We raised $250 million and we’re hiring 250+ people — not despite the AI era, but because of it. Because the better your AI gets, the more you need exceptional humans to push it, challenge it and make it sharper. AI without human intelligence isn’t security, it is just automation.
It’s time to stop coping and start protecting, with the conviction, the technology, and the people to actually turn the tide.
This Is Personal
I built TENEX because I believe we are living through the first moment in history where defenders can actually take ground from the enemy. Where the math finally works in our favor. Where the people who chose this fight, who wake up every day to protect strangers’ data, infrastructure and digital lives — finally get tools worthy of what they do.
The people joining TENEX today are not a footnote in our AI story. They are our story. Every analyst, every engineer, every threat hunter who walks through our door is proof that the bar didn’t go away when AI arrived, it went up. We are looking for the people who see that as the opportunity of a lifetime, not a threat.
