API Runtime Security

Stop API Attacks Before They Reach Your Backend

Hirefathom monitors every API call in real time — detecting credential abuse, business-logic attacks, and traffic anomalies with inline protection that deploys in minutes.

The Problem

APIs Are the New Perimeter. Most Tools Miss What Matters.

WAFs block known attack signatures. API gateways enforce schema and rate limits. SAST tools find vulnerabilities at design time. None of them watch how your API is actually being used at runtime. Business-logic attacks and credential stuffing campaigns look like syntactically valid traffic — and they are. Only behavioral analysis sees what's wrong.

Credential Abuse

Stuffed credentials and enumeration attacks mimic real users. Rate limits don't stop low-and-slow attacks.

Business-Logic Attacks

Exploiting the way your API is supposed to work — price manipulation, BOLA, workflow bypass.

Anomalous Traffic

Pattern deviations that no WAF signature can detect — sequence anomalies, volume spikes, path harvesting.

Platform Overview

Runtime Intelligence, Not Just Rules

Hirefathom sits inline beside your API layer — no traffic proxying, no DNS rerouting. A lightweight sidecar monitors every call, feeds a behavioral graph, and blocks attacks before your backend ever sees them.

Core Capabilities

Detection That Goes Beyond Signatures

Behavioral Baseline Per Endpoint

Every API endpoint builds its own traffic signature — method distributions, parameter patterns, call sequences. Deviations trigger alerts with full context.

Credential Graph Tracking

Track credential reuse, enumeration velocity, and login anomalies across your entire API surface — not just the /auth endpoint.

Inline Block or Alert

Choose per-endpoint: block on confidence threshold, alert on suspicion, or monitor silently. Zero production risk with safe observation mode.

Early Adopters

Detection That Speaks for Itself

BOLA-style object enumeration had been running on our order API for weeks. Our WAF saw syntactically valid GET requests and passed them. Hirefathom flagged the behavioral pattern — same session, sequential order IDs it had no prior context to access — within the first 24 hours of deployment. Nothing rule-based would have caught that.

We deployed the sidecar agent on a Friday afternoon. By Monday morning the credential graph had flagged over 12,000 stuffing attempts on our auth endpoint — distributed across hundreds of IPs, each under our per-IP rate limit. The credential graph saw the campaign pattern that per-IP rules completely missed.
