Not rubber stamps.
Zellic specializes in securing emerging technologies. Developers, founders, and investors trust our security assessments to ship quickly, confidently, and without critical vulnerabilities. With our background in real-world offensive security research, we find what others miss.
We’re home to the the best hacking and vulnerability research talent across the globe, earning us the reputation as the go-to security firm for teams whose rate of innovation outpaces the existing security landscape.
Let the numbers do the talking. Here's how we did in 2022:
Zellic began with a mission to deliver the best security assessments in the world. We saw a maze of subpar providers running automated tools with zero client input. Your team deserves better. We dive deep to find the unexpected ways things can break.
We keep you involved in the review process from start to finish. We ask questions. If you want us to apply certain techniques, like formal verification or fuzzing, we listen. And at each step, we walk your team through how we’re going to accomplish things.
Before Zellic, we founded the #1 CTF team worldwide. These CTF competitions attract world-renowned security researchers and white hats to exploit web, desktop, and mobile apps and cryptographic code. With us, that incredible talent secures your software.
Our engineers bring a rich set of skills and backgrounds, including cryptography, web security, mobile security, low-level exploitation, and finance.
We’re committed to research and open source. Read the latest research from our team.
Top organizations rely on Zellic to protect their systems. Give your users the security they deserve.
Safety standards are written in blood. Join us in building security solutions that advance the software industry and address the major deficiencies in software security.
