Invest in tomorrow, by securing today.

PenCrimson L.L.C. is a security holding company. It builds and runs the companies in its portfolio, and it delivers security consulting directly, under one roof and one set of operators.

Structure

Think of it the way you'd think of any parent with operating subsidiaries. Each company has its own product, its own roadmap, and its own customers. What they share is the bench, the tradecraft, and the standard for what is worth shipping.

TensorOne is the flagship and the largest of the three: agentless detection and response for the datacenter layer, in production today. Cerebro carries the threat intelligence platform and all of our offensive work, and admits members by invitation. Crimson Academy runs the training curriculum and feeds the bench that the other two hire from.

The consulting desk sits at the parent. It is how most conversations with PenCrimson begin, and it is deliberately product-agnostic until the diagnosis says otherwise.

Leadership

PenCrimson, and every company under it, is run by the same two people.

Operating principles

01

Offense-informed defense

Every defense we build starts from how an operator would get in. Both founders spent their careers on that side of the work.

02

Need-to-know handling

Decades around classified work taught us to separate what is useful to share from what would burn a source, a client, or a victim. It is the discipline Cerebro is built on.

03

Build the bench

Crimson Academy trains the bench the other companies hire from. Its curriculum is drawn from what the consulting and product teams need people to know, starting at the first terminal command.

04

Share what we learn

A method used on one defender will be used on the next. Where it is lawful and safe, we would rather the next firm not learn the hard way.
