Your Evaluation Checklist:
Ultimately, the goal of any security auditing software is to provide a snapshot of your vulnerabilities at a specific moment in time. While invaluable, these snapshots must be complemented by real-time, continuous monitoring to detect active threats as they unfold. This is particularly critical in the Web3 space, where on-chain activities can signal an impending exploit or expose a newly compromised wallet.
Traditional security tools excel at analyzing your own infrastructure and code, but they are blind to the dynamic, on-chain environment where your assets and users operate. This is the gap that must be filled. By combining periodic, in-depth audits with continuous on-chain intelligence, you build a truly resilient security framework that not only identifies latent vulnerabilities but also actively guards against emerging threats, ensuring the comprehensive protection of your digital assets.
