nullptr security

At nullptr security, we help companies proactively secure their products before attackers find the cracks. Whether you’re shipping access control hardware, IoT devices, firmware-heavy platforms, or customer-facing web/mobile apps, we offer comprehensive security audits - from full black box engagements to collaborative white box reviews. Our team brings experience from real-world offensive operations: reverse engineering complex devices, identifying 0-days, and building tooling that simulates advanced threat actors. We’ve worked with fintech companies, critical infrastructure vendors, and high-stakes communication platforms to find and fix issues before they became public problems. If your product controls access, handles sensitive data, or runs on a custom stack, we’ll help make sure it stands up to scrutiny.
