API Security Engineering
We design, harden and continuously monitor every API in your estate, REST, GraphQL, gRPC, webhooks, with discovery, runtime protection, abuse detection and the OWASP API Top 10 taken seriously.
Treat APIs as the attack surface they actually are.
Most security programs were designed when "the application" meant a website. In 2026, the application is mostly API. Mobile apps call APIs. Partner integrations call APIs. AI agents call APIs. Internal services call each other through APIs. The attack surface has moved and most security tooling has not. Our approach starts by knowing what APIs exist (discovery), continues by hardening them against the OWASP API Top 10 (engineering) and ends by detecting and blocking abuse at runtime (operations). All three layers, working together, every release.
You cannot secure what you cannot see
Discovery first. Shadow APIs, zombie endpoints and undocumented surfaces brought to light before they become breach paths.
BOLA is the new SQL injection
Authorization at the object level is where modern APIs actually break. We hunt and eliminate BOLA systematically, not just OWASP Top 10 by checklist.
Runtime defence, behavioural
WAFs alone do not stop API abuse. Behavioural analytics, anomaly scoring and bot defence at the API edge catch what signature-based tools miss.
Why API security is the #1 spend item in 2026 AppSec.
Three forces are making API security the most consequential application security investment a CISO can make.
The website-shaped attack surface is shrinking; the API-shaped attack surface is exploding. Tooling and skills must follow the traffic.
Salt Security industry data. The pattern is universal; the maturity gap between teams that invested and teams that did not is now visible at the breach level.
Every AI agent calls APIs to do real work. The integration layer is multiplying and so is the attack surface. Security must scale with it.
API Security services we offer.
Each item below is a discrete, measurable workstream we own end-to-end, with senior engineers, real timelinesand the test coverage to back it up.
API discovery and inventory
Continuous discovery of every API, documented or not. Shadow APIs, zombie endpoints and undocumented surfaces brought into the light.
Schema-aware testing
OWASP API Top 10 systematically tested: BOLA, broken auth, mass assignment, excessive data exposure. Schema-aware fuzzers find what scanners miss.
Runtime API protection
API gateways, WAF and dedicated API security platforms (Salt, Noname, Wallarm) for runtime detection and blocking of attack patterns.
Authentication and authorization hardening
OAuth 2.1, OIDC, mTLS, scopes done right. Per-endpoint authorization checks audited; the BOLA flaw class systematically eliminated.
Bot and abuse detection
Credential stuffing, scraping, inventory hoarding, defended at the API edge with behavioural analytics and ML-driven scoring.
GraphQL and gRPC security
Depth limits, complexity analysis, persisted queries, introspection lockdown for GraphQL. Authentication and rate-limiting tuned for gRPC.
We're fluent in your stack.
Vendor-agnostic by design. We pick the right tool for the problem in front of us, not the one our partner discounts apply to.
Real engagements. Real numbers.
Discovered 340 undocumented APIs in production
Continuous discovery surfaced shadow APIs from years of "temporary" deployments. Brought every endpoint under standard auth, monitoring and rate-limiting in 6 weeks.
Six reasons enterprises run API Security with Infivit.
Built for the 2026 reality of API Security: the actual buyer pain, the actual technical constraints and the actual outcomes that matter, not generic security marketing fluff.
Shadow APIs surfaced, every one.
Continuous discovery across traffic, gateways and code. Undocumented endpoints, zombie APIs and forgotten dev environments brought into governance, week one.
BOLA, broken auth, mass assignment, gone.
Schema-aware testing systematically eliminates the API-specific vulnerability classes. The flaws that scanners miss because they require business-logic understanding.
Behavioural detection, sub-minute response.
API security platforms catch abuse patterns WAFs miss: credential stuffing, BOLA exploitation, scraping at scale. Detected in under 60 seconds, blocked autonomously.
OAuth 2.1, mTLS, scopes audited.
Authentication and authorization patterns audited across every endpoint. Per-resource checks, fine-grained scopes, no broken-auth findings on production APIs.
Credential stuffing and scraping, blocked.
Behavioural analytics and ML-driven scoring at the API gateway. Legitimate traffic preserved; abuse patterns blocked before they reach the application.
Modern API protocols, treated seriously.
Depth limits, complexity analysis, persisted queries for GraphQL. Auth and rate-limiting tuned for gRPC. Modern protocols get modern security, not REST patterns retrofitted.
