Control design
Controls that fit the product
Security designed around how your product actually works — trust boundaries, session models, and review workflows built in from the start, not bolted on after.
Root-cause security engineering
Fix the root cause, close the whole class.
We design and harden the controls inside your apps and APIs, down to the root cause. Delivered end-to-end by a principal researcher, never a bench.

What we do
For teams shipping mobile apps and APIs whose threat model has outgrown the checkbox assessment.
Application & mobile hardening
Hardening that survives real attackers
Mobile apps, embedded SDKs, request signing, and runtime protection — hardened for the environments they will actually run in.
API authorization
Authorization you can reason about
Ownership models, tenancy boundaries, and abuse resistance you can explain to an auditor and defend against a researcher.
Review & remediation
Findings your engineers can ship
Every issue arrives with replication, root cause, and a remediation path — not a severity label and a PDF.
Who you'll work with
Savana Labs is one principal, not a bench. The person on the intro call is the person in your codebase.
Every engagement is delivered end-to-end by the founding principal — a security engineer and researcher with over a decade inside high-scale fintech, consumer, and gaming platforms. Discretion cuts both ways: we don't name clients, and we don't market people. You'll meet the principal on the first call.
How an engagement runs
Intro call
Thirty minutes, technical, no sales deck. Bring the problem — if we're not the right fit, we'll say so and point you somewhere better.
Scoped proposal
Fixed scope, fixed price, named deliverables. Written to pass your vendor-risk and procurement review without a fight.
The work
Findings arrive as they land — replication, root cause, remediation path — not in a PDF six weeks later. You always know where things stand.
Until it's fixed
We stay through remediation. Success is the fix shipped and verified, not the finding filed.
