We hack you,before attackers do.
One missed vulnerability can cost you a quarter of revenue, plus the customers and deals you spent years winning. We find the holes first, prove they’re real, and show you how to close them.
Most expensive breaches start as ordinary product gaps.
Exposed APIs, loose storage, cloud tables, and access rules that moved faster than the checks around them. We look for those first.

Four steps from first call to a shipped fix.
The process stays narrow, documented, and easy for engineering to follow.
A 30-minute call sets boundaries, test accounts, and the disclosure path. No broad access. No surprise production activity.
AI-assisted agents and human researchers probe the product surface faster than a manual review can cover alone.
Every lead is reproduced by a human. If we cannot prove a real exploit path safely, it does not become a finding.
Your team gets a concise report with proof, impact, and a fix path. We stay available while the patch ships and beyond.
We think like an attacker. We report like an ally.
The work is aggressive. The handoff is calm. Your engineers get the shortest path from confirmed issue to shipped fix.
Accounts, teams, files, invites, API keys, webhooks, billing. We go after the logins and access controls that break when you ship fast, the same gaps real attackers use.
Every finding comes with bounded, reproducible proof: exactly what broke and what stayed safe. We never touch your customer data to make the point.
Each report names the affected system, the steps to reproduce, the real-world impact, and the fix. Your team can verify it in minutes and ship the patch the same day.
A report your team can act on today.
A clear, bounded proof your engineers can reproduce and fix, not another scanner dump.
- The affected system, in plain English
- Steps your team can follow to reproduce it
- Proof that the impact is real
- What an attacker could do with it
- A clear fix your engineers can ship
- Bounded testing that never touches your real customer data
Aggressive on bugs. Careful with your business.
Peak is built for founders, CTOs, and engineering teams at AI apps, devtools, fintech, healthcare, and B2B SaaS.
Controlled test accounts and minimal safe samples are the default. Production customer data is off limits.
A critical finding means we confirmed real impact. Weak scanner output gets downgraded or discarded before you see it.
Careful first contact, calm communication, and details routed to the right people before anyone else hears about it.
You do not need a security team in place first. We give fast-moving companies a concrete process for finding and fixing issues.
Questions teams ask first.
Is this just a scanner?+
No. Scanners find noise. We reproduce real exploit paths by hand and discard anything we can't prove, so every finding you see is a confirmed, bounded issue.
Will you touch our customer data?+
Never. We work from controlled test accounts and minimal safe samples. Production customer data is strictly off limits.
What do we get?+
A concise report: the affected system in plain English, reproduction steps, proof of real impact, and a fix your engineers can ship the same day.
How fast can we start?+
A 30-minute scoping call is all it takes to begin. You do not need a security team in place first.

Book a 30-minute call. We will walk through your product, how we test safely, and what we would go after first.
