API Security

Install the Treblle SDK

One integration captures all API traffic with zero added latency. Security checks run asynchronously in Treblle's infrastructure, outside your API's request path.

Every request is scanned

Full request and response bodies are evaluated against the OWASP API Top 10, SQL injection patterns, IP reputation data, shadow endpoint signals, and 20+ additional threat checks in real time.

Threats are scored and surfaced

Each flagged request receives a low, medium, or high threat score with full context. Your security team sees exactly what was detected, in which request, and why it was flagged.

What is API Security?

Runtime protection for every request your APIs handle

API security is the practice of protecting APIs from unauthorized access, misuse, and attack through runtime analysis of every request and response. Modern API attacks exploit logic flaws, authentication weaknesses, and data exposure patterns that perimeter defenses and periodic pen tests cannot catch.

Treblle provides continuous runtime API security monitoring, scanning 100% of traffic against the OWASP API Security Top 10, injection attacks, IP reputation signals, and shadow endpoint exposure, with every flagged request logged in full for your security team to act on.

Buyer's Guide to API Observability

Full Traffic Coverage

100% of API traffic scanned against the OWASP API Top 10

Periodic pen tests and sampled scanning leave windows where attacks go undetected. Treblle evaluates every request against the full OWASP API Security Top 10 continuously, analyzing complete request and response bodies rather than just headers or metadata. Threats that surface-level tools miss entirely are caught here.

Full Traffic Analysis

Every API request is analyzed with no sampling, no approximations. Security checks run against 100% of your traffic so nothing slips through.

Deep Payload Inspection

Security analysis covers full request and response bodies, not just headers or metadata. Catches threats that surface-level monitoring tools miss entirely.

OWASP Top 10 API Checks

Every request is evaluated against the OWASP API Security Top 10 automatically. Continuous coverage without manual pen testing or periodic scan windows.

Threat Detection

Real-time threat scoring without parsing security logs

Each request receives a clear low, medium, or high threat rating across all active checks simultaneously. SQL injection attempts are flagged before they reach your data layer. Requests from IPs with known threat intelligence hits are identified the moment they connect. No log parsing required to act on any of it.

Threat Level Scoring

Each API request receives a clear low, medium, or high threat rating across multiple checks, giving teams an actionable signal without parsing raw security logs.

SQL Injection Detection

Identifies SQL injection attempts in real time across all API traffic. Flags malicious payloads before they reach your data layer.

IP Reputation Checks

Evaluates the reputation of every IP hitting your APIs against known threat intelligence. Flags requests from compromised or malicious sources automatically.

Shadow Exposure

Detect shadow APIs and hidden endpoints before attackers do

Shadow APIs, undocumented services operating outside your known inventory, are the first places attackers look. Treblle surfaces them at two levels: unknown services your inventory never captured, and undocumented endpoints hiding within APIs you already know about. Consumer fingerprinting adds a behavioral layer, distinguishing legitimate traffic patterns from suspicious actors across every request.

Shadow API Detection

Automatically identifies undocumented APIs and endpoints operating outside your known inventory, eliminating the blind spots attackers exploit first.

Shadow Endpoint Detection

Surfaces undocumented endpoints hiding within known APIs, not just unknown services. Catches the granular exposure that API-level discovery alone misses.

Consumer Fingerprinting

Tracks unique API consumers by device, user agent, and behavioral patterns. Helps you distinguish legitimate traffic from suspicious actors.

Connected Intelligence

Security intelligence that connects across your entire platform.

A compliance violation detected in API Compliance enriches the security context for the same endpoint in API Security. An observability anomaly feeds into threat scoring. Treblle connects signals across your full platform to surface threats that no single product scanning in isolation could catch, giving your security team a unified picture rather than disconnected alerts.

Cross-Product Security Intelligence

Connects signals across compliance, observability, and security into a unified threat picture. A compliance violation in one product enriches the security context in another.

Related Capabilities

Treblle works best when working in unison. Check out other capabilities that will help you make the most out of your API landscape.

API Compliance

Runtime checks for GDPR, PCI-DSS, HIPAA, and CCPA run alongside security scanning, with compliance signals feeding directly into threat context.

API Discovery

Know every API in your inventory before you secure it. Discovery feeds the baseline that shadow API detection measures against.

API Observability

The same traffic capture that powers observability simultaneously feeds security scanning, with no additional instrumentation required.

API Security: Common Questions

API security is the practice of protecting APIs from unauthorized access, misuse, and attack. It covers authentication and authorization controls, input validation, threat detection, and continuous monitoring of API traffic. Modern API security goes beyond perimeter defenses to include runtime analysis of every request and response, because most API attacks exploit logic flaws rather than network vulnerabilities.

The OWASP API Security Top 10 is a list of the most critical API security risks, maintained by the Open Web Application Security Project. It includes risks such as broken object level authorization (BOLA), excessive data exposure, lack of resource and rate limiting, and injection attacks. Treblle evaluates every API request against the full OWASP API Security Top 10 automatically and continuously.

Treblle's security scanning runs asynchronously alongside the observability data capture. The lightweight SDK captures request and response data with zero added latency, and security checks run in Treblle's infrastructure rather than in your API's request path. Your API performance is unaffected.

Shadow APIs are undocumented or unmanaged APIs and endpoints operating in your infrastructure without formal oversight. They represent a significant security risk because they fall outside your standard security controls. Treblle's shadow API detection automatically identifies both unknown services and undocumented endpoints within known APIs, flagging them for review before they become a breach vector.

API security testing is performed at specific points in time, typically during development or before releases, to find vulnerabilities before they reach production. API security monitoring is continuous, evaluating live traffic in real time. Treblle provides runtime security monitoring that runs against 100% of production traffic continuously, complementing rather than replacing pre-release security testing.

Treblle performs deep payload inspection on every request, analyzing full request and response bodies rather than just headers or metadata. SQL injection detection evaluates request payloads in real time, flagging malicious patterns before they reach your data layer. Every flagged request is logged with full context for review.
