Find what ordinary testing was never designed to see.
Expose unknown vulnerabilities, robustness defects and interoperability failures by intelligently challenging protocols, interfaces, APIs and file formats—before an attacker or a field failure does.
Go beyond expected behavior.
Traditional tests prove that a system works when inputs are valid. Defensics probes what happens when inputs are malformed, unexpected or hostile—the conditions that reveal exploitable weaknesses.
Protocol-aware intelligence
The generational fuzzing engine understands the rules of each input type, creating targeted negative tests instead of merely random mutations.
Faster time to fuzz
Start quickly with hundreds of maintained suites spanning protocols, interfaces and file formats—without building every test harness from scratch.
Actionable evidence
Contextual logs, message sequences, CWE mapping and single-case reproduction help engineering teams isolate, fix and verify each issue.
Custom coverage
Extend testing with template fuzzers, SDK Express, Universal Data Fuzzer or the Defensics SDK for proprietary input types.
Development-life-cycle fit
Bring repeatable fuzz testing into traditional SDL, CI/CD and DevSecOps checkpoints through rich APIs and data export.
Supplier collaboration
Create encrypted remediation packages so suppliers can reproduce a failure and collaborate securely on a validated fix.
From interface to verified fix.
A repeatable workflow converts complex security testing into clear engineering action.
Discover
Identify the test target, protocol layers and valid communication path.
Challenge
Generate systematic malformed and unexpected inputs with protocol awareness.
Observe
Use instrumentation and SafeGuard checks to detect anomalous behavior.
Remediate
Recreate the precise trigger, correct the weakness and verify the fix.
Turn “secure by design” into testable evidence.
For products with digital elements, vulnerability handling begins before release. Defensics helps teams exercise exposed interfaces, uncover unknown weaknesses and preserve repeatable results that support a disciplined secure-development process.
- Validate communication-protocol robustness
- Detect implementation weaknesses before release
- Automate repeatable security testing in DevSecOps
- Generate evidence for remediation and re-testing
Test every conversation around the vehicle.
Connected vehicles expand the attack surface across ECUs, gateways, telematics, diagnostics, wireless links and infrastructure. Protocol-aware fuzzing helps reveal what happens when those conversations become malformed or hostile.
- CAN Bus and CAN FD
- DoIP, SOME/IP, gPTP and SRP
- Telematics, gateways and infotainment
- ADAS, autonomous and connected systems
One platform. Many interfaces.
Choose vertical bundles or individual suites, then extend them for proprietary protocols and formats.

Security without slowing engineering.
Defensics gives each stakeholder the evidence needed to make confident release and procurement decisions.
Product security
Uncover zero-day and unknown vulnerabilities before they become incidents, patches or recalls.
Development
Shift negative testing earlier and reproduce failures with a single minimized test case.
Quality assurance
Validate robustness, interoperability and resilience without needing access to source code.
Procurement
Assess third-party software and devices before bringing them into enterprise or lab environments.
