Capabilities

We're new.
We won't pretend otherwise.

No borrowed logos, no invented case studies, no metrics we can't stand behind. What we can show you: the exact classes of finding we surface, written the way our reports read — and, when you're ready, a real redacted sample under NDA.

01Representative findings

The bugs we hunt

Real vulnerability classes we specialize in, written to show depth and how we report.

Illustrative — not tied to any client

WebCritical

JWT algorithm confusion → cross-tenant account takeover

Root
An RS256 verifier that also accepts HS256 lets an attacker sign tokens with the public key.
Impact
Authenticate as any user, in any tenant.
Fix
Pin the algorithm; separate verification keys by type.
APIHigh

Broken Object-Level Authorization (BOLA / IDOR) at scale

Root
Sequential object IDs plus a missing ownership check expose every record via one enumerable endpoint.
Impact
Bulk data disclosure across the customer base.
Fix
Per-object authorization on every read; non-enumerable identifiers.
AIHigh

Indirect prompt injection coerces an agent into data exfiltration

Root
A poisoned document in the RAG corpus rewrites the agent's instructions; a tool call ships internal context to an attacker-controlled sink.
Impact
Silent exfiltration through a 'trusted' workflow.
Fix
Content/instruction separation, tool-call allow-lists, egress controls.

OWASP LLM01 · MITRE ATLAS

NetworkCritical

Foothold to Domain Admin via Active Directory misconfiguration

Root
LLMNR poisoning → relayed credentials → Kerberoasting → an over-privileged service account.
Impact
Full domain compromise from an unauthenticated starting position.
Fix
Disable LLMNR/NBT-NS, enforce SMB signing, tier admin accounts.
CloudHigh

Cross-tenant escalation through a stale guest identity

Root
An external guest in Entra ID keeps a role assignment after offboarding; a consented app inherits it.
Impact
Lateral movement across the tenant boundary.
Fix
Guest lifecycle governance, periodic access review, least-privilege consent.
LogicHigh

Race condition turns a one-time coupon into infinite credit

Root
Concurrent redemption requests bypass a check-then-act balance update.
Impact
Direct financial loss — invisible to a CVE scanner.
Fix
Atomic decrement / idempotency keys / row-level locking.

02Who runs your test

Senior-led. No juniors on the crown jewels.

Every engagement is led by a senior operator, never handed to a checklist-runner. Specialisms across the team: web & API exploitation, Active Directory & cloud identity, LLM/agent red-teaming, and ISO/regulatory readiness.

Sample report

Want to see the real thing?

We keep a fully redacted sample report — a live example of how we evidence, prioritize, and write for both the board and the engineer. We don't publish it: our methods stay off the open web, and the artifact stays meaningful. Ask, and we'll walk you through it under NDA.
