Financial services, healthcare and SaaS run on exposed APIs, and the flaws that matter most are logic flaws scanners miss. Syber tests the logic behind your critical flows and proves each flaw with a working exploit.
Your APIs decide who can move money, read a statement or pass onboarding. Syber attacks those decisions the way an adversary would and proves what breaks.
Flows that let an account reach a verified state before every check is done.
Login, MFA, password reset and device-binding weaknesses across payment, wealth and account APIs.
APIs that return another customer's statements, holdings or ledger entries when an ID changes.
Amount, limit and status checks that can be skipped or reordered on transfer, settlement and callback APIs.
Consent steps that can be bypassed as data moves to partners and aggregators.
Evidence maps to PCI DSS, SOC 2, ISO 27001 and DORA, plus regional financial regulators.
Patient portals and health APIs hold the most sensitive data you process. Syber tests the paths that expose it and proves each one with a working exploit.
Reports, prescriptions and records reachable across patients or tenants through app and API logic.
Health APIs that return a record to the wrong caller.
Responses that carry more personal data than the screen shows, widening what one flaw can leak.
Evidence supports HIPAA risk analysis and regional data-protection rules.
In a multi-tenant product, one missing check can expose every customer. Syber tests the boundaries between tenants, roles and tokens, and proves each break.
Data that leaks across tenants through shared APIs, exports or caches.
Admin, owner and cross-org actions reachable from a lower-privilege session.
API keys, JWTs and OAuth tokens that can do more than their scope allows.
Prompt injection, unsafe agent actions and data leakage in the LLM features you ship.
Evidence maps to SOC 2 and ISO 27001.
Before you invest, Syber tests a target's or a portfolio company's in-scope systems with that company's written authorization, and shows you what is exploitable, with proof. After the deal, Sentry retests to confirm the fixes held.
