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 security tooling, or use off-the-shelf options?

Manual line-by-line code review is essential, but it’s not enough. Modern protocols are too complex for even the best human reviewers to catch every edge case. Some types of bugs are extremely difficult for the human eye to find, but they can be uncovered by the right tools.

Widely available open-source tools (such as static analyzers) can be helpful, but they often do not offer state-of-the-art capabilities, and are sometimes not properly maintained, or simply unfit for specific context.

How does Veridise handle it?

At Veridise, we’ve built a suite of powerful in-house tools to complement our manual reviews:

• Vanguard — Static analyzer for smart contracts
• OrCa — Specification-guided fuzzer
• ZK Vanguard — Static analysis tool for ZK circuits
• Picus — Formal verification tool for ZK circuit determinism

Building these tools isn’t easy, which is why we invest heavily in developing them in-house. In fact, about one-third of our team is dedicated solely to building custom security tools for our auditors. This gives Veridise a significant edge over firms that rely entirely on open-source alternatives only.

3. Can I see what’s happening during the audit — or just the final report?

One of the most common client frustrations in the industry is the lack of transparency. From a client’s perspective, the process can feel like a black box: you engage an auditor, they ‘disappear’ for few weeks, and then return with a report — sometimes showing just a handful of findings. It’s only natural to wonder: What actually happened during that time? How much effort was invested? Without visibility, it’s difficult to assess the effort and depth of the work.

How does Veridise handle it?

We built AuditHub to eliminate this transparency gap.

AuditHub is the platform we use to facilitate all our audits — and it gives clients real-time insight into every step of the process. As a client, you can:

• Track bugs real time as they’re discovered
• View internal discussions between security analysts
• Participate directly in the conversation
• Access tooling outputs in real time
• Re-run our tools to verify that issues have been resolved

As far as we know, Veridise is the only blockchain security company offering this level of transparency and client collaboration throughout the audit process.

4. What clients have you worked in the past — and have they come back for audits later?

Past performance is one of the clearest indicators of audit quality. If an audit firm has only worked on small, one-off projects or cannot name any returning clients, that is a red flag. The most trusted auditors build long-term relationships with technically demanding teams who return for multiple engagements.

You should also ask about experience in your specific domain. For example, if you are building a zkVM application, it is worth asking whether the firm has audited similar projects before.

How about Veridise?

At Veridise, we have audited the internals of some of the most advanced and technically complex protocols in blockchain and zero-knowledge, including:

• RISC Zero (6 audits and counting + CI/CD tool integration) and zkVM applications built on top
• Succinct (6 audits and counting + CI/CD tool integration)
• Sygma Labs (8 audits)
• Mina (2 audits)
• …and more, you can find all of our audits in Audits Archive

These teams return to Veridise again and again because they trust our people, tools, and process — and consistently see the value we bring. Significant part of our business comes from existing clients.

5. Can I hear what your clients say about working with you?

It’s easy to claim expertise. What matters is whether real clients trust the firm enough to speak publicly about their experience. Look for published testimonials, case studies, or recorded interviews that demonstrate credibility and client satisfaction.

Ideally, try reaching out directly to a previous client — especially one building in a similar category as yours. Firsthand experiences are one of the most reliable ways to gauge the quality, communication, and overall reliability of a security firm.

How about Veridise?

We let our clients speak for us. You can explore our client testimonials on this page and hear directly from them in the video below. See individual video clips from RISC Zero, Linea, o1Labs and Demox Labs.

We also encourage you to reach out directly to any of our clients to learn more about their experience working with Veridise. To find clients in your niche (such as ZK, zkVM, L1/L2, DeFi, or cross-chain) you can visit our Audits Archive.

6. Who will actually audit my code, and can I verify their credentials and previous experience?

When evaluating a blockchain security audit firm, the company name gives you a general idea of their capabilities and general reputation. Different companies have varying processes and bug detection tools at their disposal. However, at the end of the day, the quality of your audit depends on the individual security auditor reviewing your code.

Visit many security firms’ websites, and you’ll struggle to figure out who is actually doing the audits. Bios are missing, credentials are vague, and LinkedIn searches only go so far.

How does Veridise handle it?

At Veridise, we believe trust starts with transparency. That’s why we publicly showcase detailed profiles for every security analyst on our team — including academic backgrounds, technical expertise, notable academic publications, and past audit highlights. You’ll know exactly who’s working on your code and why they’re qualified to do so. Explore the profiles on our team page

7. Does your team have researchers in the security space?

Great talent can come from both inside and outside of academia. But depending on the complexity of your protocol, especially in ZK systems or advanced cryptographic designs, deep technical expertise is essential. Securing such systems requires mastery of cryptographic principles, protocol design tradeoffs, and formal verification methods, which take years or even decades of study and hands-on research experience.

Academic publications can be a strong signal of whether a team is working at the cutting edge, especially in emerging fields like ZK security.

How about Veridise?

Academic rigor is in our DNA. Veridise was founded by researchers from the University of Texas in Austin who set out to bring provable assurance to the blockchain industry. Our team includes multiple PhDs, and our team members have collectively published over 100 academic papers.

We’ve contributed original research in formal verification, ZK and smart contract security. You can find the most relevant smart contract and zero-knowledge security related publications on our Publications page.

Final thoughts about our capabilities at Veridise

With so many blockchain security firms in the market, it can be hard to distinguish between them. On the surface, most seem to promise the same things: expertise, reliability, and thorough code reviews.

But once you look closer, the differences become clear. Not all audit partners bring the same level of depth, tools, or transparency. And in a space where a single missed vulnerability can result in catastrophic loss, these differences are everything.

At Veridise, we believe we’ve struck the right mix — combining our strong academic experience, investment in in-house tool development, and modern infrastructure to facilitate audits that go deeper and uncover more vulnerabilities.

Here’s a summary of what we believe sets Veridise apart:

• Top-tier researchers and engineers — We don’t hide who’s doing the work. Every member of our audit team has a public profile. You know exactly who’s reviewing your code and why they’re qualified.
• Custom-built tools — We’ve developed proprietary tools like Vanguard, OrCa, ZK Vanguard, and Picus to surface vulnerabilities that off-the-shelf solutions can’t detect. These tools give our clients a critical edge.
• AuditHub: radical transparency — We believe audits shouldn’t be a black box. With AuditHub, our clients get full visibility into the entire audit process: from bug discovery to remediation tracking, real-time communication, and reproducible tooling output.
• Proven experience with industry leaders — Teams like RISC Zero, Succinct, and Mina have trusted us with multiple audits in highly complex domains. See more in our Audits Archive.
• Academic roots with real-world impact — Our approach is grounded in formal methods and academic research. See our Publication page for more.
• A methodology designed for completeness — Each audit includes at least two dedicated security researchers who collaboratively review the entire codebase. Combined with in-house tooling and protocol-specific expertise, our approach ensures system-wide understanding.

We hope this article helps you better evaluate your future blockchain security partner. Whether you’re launching a new protocol, securing dapp, or refining ZK implementation, the right audit partner can make all the difference.
