Modern Security for Traditional Systems

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.

What We Cover

We focus on critical attack surfaces that matter most in Web2 environments:

  • Authentication and authorization logic

  • Session management and user impersonation risks

  • Broken access controls (e.g., IDOR, privilege escalation)

  • Business logic and edge case abuse

  • API misuse and insecure integrations

  • Insecure storage or transport of sensitive data

  • SSRF, injection, and remote code execution vectors

  • Race conditions and concurrency issues

  • CI/CD pipeline security and infrastructure weaknesses

Reviews can be scoped for specific applications, microservices, monoliths, or third-party SaaS integrations - whether web-based, mobile, or hybrid.

FAQ

What is a Web2 Security Review?

It's a structured security assessment of traditional application codebases - such as web servers, APIs, mobile apps, or cloud configurations. The goal is to identify vulnerabilities that could lead to unauthorized access, data leaks, or service disruption.

How is this different from a typical security agency?

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.

How do you ensure reviewer quality?

All Cantina reviewers are vetted through peer-reviewed competitions and real-world assessments.

Can I combine a Web2 review with a smart contract audit?

Yes. If your protocol involves both on-chain and off-chain components, we can bundle both into a coordinated engagement.

Do you provide a formal report?

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.
