Choosing the right security auditor is one of the most critical decisions your team will make. With so much at stake, a single vulnerability can lead to reputational damage, financial loss, or worse. The wrong choice can leave you vulnerable or offer a false sense of security.

The right audit partner becomes a long-term ally in ensuring your protocol is secure and ready for real-world threats. Below are the essential questions you should ask every security auditor — and how Veridise answers each one.

1. How many security analysts will review my code — and what’s your audit methodology?

Many audit firms assign individual auditors to separate parts of the codebase. This approach limits visibility: one auditor might focus on Module A, another on Module B, and neither gains a full understanding of the entire system. This siloed approach makes it easier to schedule people, but it risks missing architectural flaws that span multiple parts of the codebase.

You want to ensure that your entire codebase is reviewed with full context, not in isolated silos.

How does Veridise handle it?

At Veridise, we take a fundamentally different approach. We emphasize defense-in-depth, redundancy, and collaboration:

  • Two auditors minimum per project: Every audit is handled by a team of at least two dedicated security researchers, not just a single analyst working in isolation.
  • Full codebase coverage by both auditors: Rather than dividing the code into separate silos, both auditors review the entire codebase. This means every line is seen by two independent sets of eyes — enabling a shared understanding of how all parts of the system interact.
  • Lead auditor with domain-specific expertise: Each audit is anchored by a lead auditor with deep knowledge of the specific language, framework, or protocol under review. This ensures the audit is grounded in recent domain-specific real-world experience.
  • Manual & tool-assisted review: We combine line-by-line manual code inspection with advanced tooling developed in-house. This hybrid approach lets us identify both logic-level vulnerabilities and subtle issues that tools or human reviewers alone might miss.

With this methodology we improve bug discovery, reduce blind spots and provide our clients with greater confidence in their code.

2. Do you develop your own…
