Security in Web3 requires more than technical depth. It demands structure, continuity, and precise execution guided by expertise. As organizations scale, their security needs evolve -from architecture-informed reviews to incident readiness, repeatable testing and beyond.
We saw the need for a cohesive system, one designed to align structured execution with evolving security demands.
Today, we’re excited to announce that Spearbit has officially joined forces alongside Cantina, a unification of systems to reduce complexity through simplified acccess. This streamlines engagement across both custom and modular formats while maintaining the specialized roles and highest standards of each solution.
Two Models, One Coordinated Framework
Spearbit continues to deliver deep, high-touch security reviews for the most complex systems. These assessments are led by elite researchers, and executed with an approach that brings clarity and confidence to critical infrastructure.
Simultaneously, Cantina enables fast, flexible access to services built for scale. Teams can engage researchers through reviews, competitions, bug bounty programs, and more - all executed by the same trusted researcher network.
Aligning Access With Operational Reality
Security is rarely solved by a single solution. Mature organizations rely on multiple parallel approaches, combining custom reviews with structured testing and ongoing coordination.
Starting today, your entire security lifecycle operates within one seamless platform. No more fragmented efforts, allowing you to maximize your time doing what you do best - building for the future.
