Our core values

How the Phalanx operates

The Phalanx

We operate as one unit. Every member covers the person beside them. If one fails, we all fail; if one succeeds, we all succeed.

Extreme ownership

No "they broke it," only "we let it slip." Everyone here is a leader, and every leader owns the outcome.

Shield overlap

Look left and right. If a peer is blocked, you pair, you unblock, you extend your shield.

Built for victory

We optimize for outcomes, not comfort. We plan together, swarm together, and deliver together.

Our mission

We built the ultimate adversary so regulated enterprises can test themselves the way real attackers would.

SpartanX is The Ultimate Adversary™, an autonomous offensive platform that maps your surface inside and out, proves the ways in with evidence, and never stops. We organize with the discipline of a military unit because the adversary we are building has to be relentless, precise, and under your control. We do not fight for vanity metrics. We fight for every security team that deserves better tools than the ones they have today.
