The Adversis Approach
Built to Survive Scrutiny
Most product security and cybersecurity programs come from people who've never compromised an enterprise's critical assets or evaluated a vendor. We have. We know what passesโ€”and what doesn't.

Our risk model comes from years of offensive operations and understanding what attackers actually exploit, how they chain findings together, where the cheap wins are.

Pattern recognition from dozens of complex engagements inside enterprise environments. Not simply frameworks. Not just checklists. Accumulated intelligence about what actually leads to compromise,  and what doesn't.

It's why we can tell you what to invest in and, just as importantly, what to skip.
01
Assess
We start by understanding your goals, your buyers, and where the gaps are. We look at your security story the way a skeptical buyer would.
02
Close
We fill the gaps that actually block deals: architecture, policies, controls, evidence
03
Equip
You walk into security reviews with answers and evidence that holds up.

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.
๐Ÿ‘ Modern red office building with large blue-tinted glass windows against a bright sky.
What kind of companies do you work with?

Mostly B2B SaaS companiesโ€”typically Series A or B, with a small security team or none at all. The common thread: enterprise buyers are asking hard security questions, and the team needs help answering them.

We already use Vanta / Drata / a compliance platform.

Keep using them โ€” they're great at automating evidence collection and getting you through your SOC 2 audit. We pick up where they stop: the live security call with your prospect's team, the custom questionnaire questions that fall outside your audit scope, and pen testing that holds up when a buyer's security team actually reads the report. Instead of your CTO spending weeks figuring out what enterprise buyers expect and how to talk about your security posture, you hand it to us. Compliance platforms get you the certificate. We get you through the security review.

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

Yes. But we'll probably ask what's driving the needโ€”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.

Can you help us answer security questionnaires?

Yesโ€”and we can get on calls with your buyer's security team when needed. We've been on the other side of those calls, running vendor evaluations. We know what they're actually trying to learn and how to answer in a way that builds confidence. We've also been on both sides of a breach and can justify when controls make a difference.

How fast can you start?

Most engagements kick off within 2-3 weeks. If you have a deal on the line and need to move faster, tell usโ€”we'll see what we can do.

Do you offer one-off projects or ongoing support?

Both. Some clients need a pen test or SOC 2 sprint and we're done. Others want a retained advisor they can pull in for security reviews, architecture questions, or board prep. We structure it around what you actually need.

How much does this cost?

It depends on scope, but most companies spend less on a full engagement than they lose in delays. A pen test or gap analysis starts in the low five figures. A broader security story or compliance push scales from there based on what you actually need.

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 benchโ€”fractional expertise you can tap without hiring a full team. When you're ready to build internally, we can help with that transition too.
