Web2 Security Reviews

Web2 Security Reviews

Comprehensive reviews for traditional software code - delivered by a network of elite, independent security professionals.

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:

  • Admin panels or multisig control dashboards

  • Oracle updater scripts and backend APIs

  • Governance UIs and vote execution services

  • Web-based keepers or automation scripts

  • Authentication and session logic for protocol contributors

  • Third-party SaaS integrations tied to treasury or dev access

  • Cloud misconfigurations and key leakage risks

  • IDOR, RCE, SSRF, or off-chain injection vectors

  • API misuse, broken access control, or signing logic flaws

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.

How does team composition differ between Spearbit and Cantina reviews?

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.
