API Security Consulting
Most API breaches aren't broken cryptography — they're a gateway that checks the signature and nothing else. We design, integrate, and test the full chain: gateway policy, token validation, scopes, object-level authorization, and the telemetry to prove it works.
How APIs Actually Get Broken
The OWASP API Top 10 is a catalog of authorization mistakes — not crypto failures.
- Broken object-level authorization (BOLA). the token is valid, but nobody checks that user 42 may read order 17 — the #1 API killer.
- Signature-only JWT validation. the gateway verifies the signature but skips audience, issuer, expiry, and algorithm pinning — so any valid token from anywhere gets in.
- API keys where OAuth belongs. long-lived, unscoped keys shared across teams and pasted into repos, instead of short-lived scoped tokens.
- Immortal bearer tokens. stolen tokens that keep working for hours because nothing binds them to the client (DPoP/mTLS) and nothing rotates or revokes them.
- Unbounded GraphQL. introspection open in production, no depth or cost limits, and one query that joins its way to the whole database.
- No rate limits, no telemetry. scraping and credential stuffing look exactly like traffic when nothing counts, throttles, or alerts.
What We Deliver
Concrete, standards-based building blocks — designed, implemented, and handed over with docs your team owns.
Proof, not promises: we designed the Kong gateway layer behind Enkrypt AI’s AI-security platform — 10 custom Lua plugins, custom rate limiting on multiple identifiers, and per-project credit metering with hard limits.
Gateway Policy Design & Integration
authentication, validation, and rate-limit policy for Kong, AWS API Gateway, Azure APIM, GCP, WSO2, MuleSoft, KrakenD, Cloudflare, and IBM DataPower — matched to your traffic, not copied from a template.
JWT Validation & Token Hardening
audience, issuer, expiry, and algorithm checks done right (RFC 8725), plus sender-constrained tokens with DPoP (RFC 9449) or mTLS (RFC 8705) where theft matters.
Scope & Authorization Design
scope models that mean something, and object-level checks (FGA/ReBAC with OpenFGA or OPA) at the layer where BOLA actually happens.
OWASP API Top 10 Review
a systematic pass over your APIs against the OWASP API Security Top 10, with findings ranked by exploitability and a concrete fix plan.
GraphQL & Modern API Security
introspection policy, depth and cost limits, persisted queries, and per-field authorization for GraphQL, gRPC, and event-driven APIs.
API Security Testing & Telemetry
abuse-case test suites with k6, Postman Newman, Pytest, and Playwright, plus SIEM-ready identity telemetry so attacks surface as alerts, not incidents.
What Clients Say About Our API Security Work
In their words.
Robin PanwalaEx-Director and India Head, Cequence AI · now Founder at Acuro Capital & Acuro AIAkhil is a passionate engineer and will do everything in his power to make the project a success. A quality I love about him is — he considers your customers as his customers and takes genuine ownership of the project while adhering to strict timelines as agreed upon mutually.
Brilliant Developer. Akhil can pick up any new tech fairly quickly. Highly communicative, responsive and takes true ownership of the project from the start till seeing it through success in real production environments. I will work with Akhil again without a doubt. Please go ahead with him without a 2nd thought. If he commits to your project, he will deliver. Period.
