Most breaches don't start with a zero-day. They start with a forgotten endpoint, a misconfigured bucket or one convincing email. We find them first, and we show you how to close them for good.
What we do
Three ways to find your weak spots. One goal: close them.
Anatomy of a breach
How we'd get in.
01 / Recon
Map the attack surface
We enumerate domains, endpoints, cloud assets and exposed services, just as an attacker would on day one.
Why ShadowSee
Not another scanner report.
Every engagement is led by practitioners who explain what they found, why it matters and how to fix it.
Manual first
Humans who think like attackers
Tools give us breadth. Certified testers give you depth: chained exploits, logic flaws and abuse cases scanners never find.
Live
Findings as they happen
Critical issues reach your team the moment we confirm them, so you can fix during the engagement instead of weeks later.
Signal
Reports people actually use
An executive summary leadership can read and technical detail engineers can act on, ranked by real business risk.
Close
We stay until it's fixed
Walkthroughs with your developers, remediation guidance and a retest to confirm the gaps are closed.
How it works
From first call to clean retest.
A clear, predictable engagement, with no surprises on scope, timeline or cost.
- 01
Scope
A short call to understand your stack, goals and constraints. A clear proposal with scope and cost follows.
- 02
Attack
Our testers go to work, with live updates on critical findings throughout the engagement.
- 03
Report
Risk-ranked findings, proof of concept and precise remediation steps for every issue.
- 04
Retest
We verify your fixes and hand over evidence you can share with customers and auditors.
Security training
Your people are the perimeter. Train them like it.
Practical awareness programs for executives, managers and staff: recognizing social engineering, handling sensitive data and responding with confidence when something goes wrong.
