What you can actually buy

Core engagement
Penetration testing
A scoped attack against systems you own, with evidence and a fix path.

Adversary simulation
Red team operations
Test detection and response, not just whether a door exists.

Product security
Web application security
Auth, business logic, APIs, and the flows attackers actually abuse.

Your product, your devices
Mobile application security
Authorized testing of iOS and Android apps you develop or operate.

AWS · Azure · GCP
Cloud security assessment
Identity, exposure, and blast radius in the accounts you actually run.

Breadth with judgement
Vulnerability assessment
Wide coverage, human triage, and a list you can actually work.

When something is already wrong
Incident response
Contain, investigate, and brief leadership — without making it worse.

People and process
Security awareness & tabletop
Exercises that treat staff as partners, not punchlines.
Process
Five steps. No mystery. No midnight surprises.
01
Scope
A working session on objectives, assets, environments, and what ‘done’ looks like. You leave with a written proposal.
02
Authorize
Legal entity, Rules of Engagement, contacts, and a kill switch. No testing starts without a named signatory.
03
Test
Operators work the agreed window with a daily pulse if you want one. High-impact issues are raised as they land.
04
Report
An executive letter, a technical appendix, and a conversation. Findings are ranked by exploitability and business effect.
05
Retest
You fix; we verify. The engagement is not finished because a PDF went out.
Proof
Work, with names attached

Northline Payments
Fintech
“They found an authorization gap our own scanners had marked as informational. We shipped the fix before the next card-scheme review.”
Daniel Cho, CTO

Vale Health
Healthcare
“The tabletop was uncomfortable in the right way. For the first time the clinical and IT leads told the same story.”
Nia Okoye, CIO

Arbor
B2B SaaS
“They treated our staging environment like production. That is the only reason I trusted the report.”
Elena Voss, VP Engineering

Kestrel Capital
Financial services
“Quiet, precise, no theatrics. Our audit committee actually read the executive letter.”
Samir Haddad, CISO
Informational
If you searched “hire a hacker”
You are in the right place only if you want authorized testing of systems you control. Phone access, surveillance, and crypto “recovery” by attacking third parties are not services. They are crimes. We publish that in plain language so the wrong brief never reaches an operator.
