Product Security Assessment for SaaS

Answer the architecture questions

that close deals

Enterprise buyers will dig into your architecture. Authentication, data flows, access controls — be ready before the call.

How do you isolate tenant data? What happens when someone leaves a customer's org? Who can access what, and how do you prove it?

We help engineering teams build security into the product from the start, and prepare for the technical questions that come with larger customers.

Sophisticated prospects don't just read your SOC 2 report. They dig into how your product works. How do you isolate tenant data? What happens when an API key gets leaked? Who can access what across your data layer - and how do you prove it?

We assess your application architecture against the specific questions enterprise security teams ask during procurement. Then we give your engineering team practical, prioritized guidance they can ship without slowing down — embedded in the development workflow, not bolted on after the fact.
Threat modeling mapped to your actual attack surface and buyer-facing risk
Authentication and authorization architecture review (SSO, RBAC, token management)
Multi-tenancy model and tenant data isolation validation
API security assessment — endpoint exposure, rate limiting, input validation, broken object-level authorization
Secure SDLC integration — where security checks fit in your CI/CD pipeline without becoming a bottleneck
Remediation guidance prioritized by what enterprise buyers specifically ask about
Who it’s for
Engineering leaders at SaaS companies entering enterprise sales cycles where buyers' security teams want architecture answers, not just compliance certificates.
Outcome
Walk into security review calls knowing your architecture holds up—because you've already pressure-tested it against the questions they're going to ask.

FAQ

Questions We Hear Before the First Call

We've worked with dozens of SaaS teams navigating enterprise security. Here's what usually comes up.

When should we do a product security review vs. a pen test?

A pen test finds vulnerabilities in what you've built. A product security review looks at how you've built it — authentication flows, tenant isolation, data access patterns — and evaluates whether the architecture will hold up to enterprise buyer scrutiny. If buyers are asking architecture questions your pen test report doesn't answer, that's a sign.

We're a small engineering team. Will this slow us down?

The opposite. We give your engineers specific, prioritized guidance they can implement in their existing workflow. We're not handing you a 40-page checklist. We're telling you the three things that matter for your next enterprise deal and how to address them without rearchitecting your product to the extent possible.

We just need a pen test. Is that something you do?

Yes. But we'll probably ask what's driving the need—because a pen test is often part of a bigger picture (a deal in motion, a compliance requirement, a buyer's security review). If you genuinely just need a clean report, we can do that, validation and retesting included. If there's more to untangle, we'll tell you.

Do you review our code?

We review architecture, not necessarily line-by-line code, although if code-level review is warranted for a specific concern, we'll tell you. We look at how your application handles authentication, authorization, data isolation, API security, and the trust boundaries that enterprise buyers specifically ask about.

Is Adversis a good fit if we don't have a security team yet?

That's most of our clients. We act as your security bench—fractional expertise you can tap without hiring a full team. When you're ready to build internally, we can help with that transition too.
