Traditional API testing misses edge cases — continuous fuzzing ensures your APIs are secure even under unpredictable real-world inputs.

​
Why Continuous API Fuzzing Matters

Most API vulnerabilities appear only when APIs receive malformed, unexpected, or extreme input values.
These include:
  • Injection payload variants
  • Broken validation logic
  • Serialization & parser edge-case failures
  • Crashes due to type confusion or oversized requests
Snapsec continuously fuzzes your APIs to detect issues before attackers do.
Identify high-risk injection and input-handling flaws missed by normal testing
Detect crashes, unexpected responses, and hidden API behaviors
Automatically generate malformed, random, and adversarial inputs
Continuously run fuzzing campaigns across all API endpoints

​
How Snapsec Performs Continuous Fuzzing

1

Discover API Endpoints

Snapsec maps all API routes, parameters, headers, and request bodies automatically.
2

Generate Adversarial Inputs

AI-driven payload engines produce malformed, randomized, and mutation-based fuzz inputs tailored to each endpoint.
3

Execute Fuzzing Campaigns

APIs are stress-tested with multiple request variations across methods, schemas, and parameter types.
4

Monitor Behavior & Failures

Snapsec analyzes response codes, errors, latency spikes, crashes, and parser inconsistencies.
5

Report Weaknesses Automatically

Any abnormal or risky behavior is converted into a vulnerability report with reproduction steps and fixes.

​
What Problems This Solves

Hidden Injection Paths

Surface injection behaviors triggered only under malformed or edge-case inputs.

Validation Weaknesses

Detect missing validation, weak type checks, and bypassable input rules.

Parser & Logic Crashes

Identify API crashes caused by unexpected payload sizes, formats, or types.

​
Key Benefits for Your Security Team

Continuous Protection

Fuzzing runs automatically — catching regressions as soon as they are introduced.

Deep Input Coverage

Explore request bodies, parameters, arrays, nested JSON, and HTTP behaviors.

Low False Positives

Behavioral anomaly detection ensures issues are validated before reporting.

Developer-Ready Output

Detailed crash logs, reproduction payloads, and fix guidance for engineers.

​
Example Findings

API returns a 500 error when receiving oversized arrays in JSON payloads.
Login endpoint accepts raw object instead of expected string → validation bypass.
XML payloads cause parser crash exposing stack traces.
Unexpected characters in query params reveal hidden debug behavior.

​
What Happens After Detection

1

Capture Failure Evidence

Snapsec stores full request/response logs, parser errors, and stack traces.
2

Classify Weakness Type

Injection, crash, validation bypass, type confusion, or logic flaw.
3

Generate AI Fix Guidance

A detailed remediation plan is generated automatically.
4

Send to VM for Tracking

Issues are synced instantly to Snapsec VM for assignment and SLA handling.
