Comprehensive reviews for traditional software code - delivered by a network of elite, independent security professionals.
Cantina makes it easy to commission in-depth reviews of traditional Web2 contracts. From critical API integrations and authentication flows to complex SaaS logic and supply chain infrastructure, our experts uncover implementation-level risks before they become exploits. Clients choose Cantina for our speed, quality, and flexibility - backed by a distributed network of top-tier engineers with proven security expertise.
Whether you’re releasing a customer-facing application, integrating with third-party systems, or scaling critical backend operations, our reviewers surface high-confidence vulnerabilities while also advising on secure design improvements and long-term resilience.
We focus on critical attack surfaces that matter most in Web2 environments:
Reviews can be scoped for specific applications, microservices, monoliths, or third-party SaaS integrations - whether web-based, mobile, or hybrid.
Security issues in traditional systems remain one of the leading causes of loss in Web3. From dashboards and admin panels to APIs and cloud services - your off-chain infrastructure is just as critical as your contracts.
Partner with Cantina to secure the full picture.

Cantina uses a decentralized model. You're matched directly with elite security researchers - no bloated overhead, no junior staffing. Reviews are scoped, executed, and delivered through a secure, transparent platform.
All Cantina reviewers are vetted through peer-reviewed competitions and real-world assessments.
Yes. If your protocol involves both on-chain and off-chain components, we can bundle both into a coordinated engagement.
Yes. You'll receive a PDF report with detailed findings, severity levels, technical explanations, and remediation suggestions. We also offer fix validation as an optional follow-up.
Spearbit provides high-end security reviews with teams hand-selected from a network of top Web3 security talent. Spearbit reviews must include a minimum of two Lead Security Researchers. These reviews are designed for depth and specialization, assessing some of the most complex decentralized systems in the ecosystem.
Cantina Reviews allow for more flexibility, providing you with a team of expert security researchers without Spearbit’s two Lead Security Researcher minimum. This model allows for faster onboarding and/or budget-flexibility while leveraging the same pool of expert security talent.
