Best Protocol Fuzzer **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Computer & Network Security | Enterprise (> 1000 emp.) **Reviewed Date:** June 25, 2019 **What do you like best about Defensics?** Defensics helps us toh identify the protocol level vulnerability . Awesome IP stack breaker when it comes to fuzzing the protocol **What do you dislike about Defensics?** Integration Part : Loding the suites and making the server up takes a lot of time . Don't have any details documentation regarding the protocol used for defensics **Recommendations to others considering Defensics:** Automate the tool to some more extend **What problems is Defensics solving and how is that benefiting you?** Troubleshooting take lot of time . Please make it bit automated . So any end users should be ease to use . ### 2. Great tool to test the Protocols. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Electrical/Electronic Manufacturing | Enterprise (> 1000 emp.) **Reviewed Date:** July 25, 2019 **What do you like best about Defensics?** One of the great product of synopsys. With the help of synopsys defensics we can test the protocols and it will provide the accurate results of the test and helps in our OT testing of the devices. It contains all the protocols which we need in our testing. Major part of this tool is its having bunch of test cases. **What do you dislike about Defensics?** In synopsys defensics we cannot buy multiple licences for single protocol and we have to wait for complete the test its takes more time to complete minimum one day for one protocol. **Recommendations to others considering Defensics:** if possible allow multiple licenses for single protocol. **What problems is Defensics solving and how is that benefiting you?** Defensics gives the accurate results so we can easily check the given results is true or false positive by giving the test case number from some range to other range where exactly device goes down. for example ipv4 protocol if its fail between 35000 then we will give 30000-40000. ### 3. Defensics for fuzz testing REST APIs **Rating:** 3.5/5.0 stars **Reviewed by:** Verified User in Security and Investigations | Enterprise (> 1000 emp.) **Reviewed Date:** January 02, 2019 **What do you like best about Defensics?** It's relatively easy to get started. The tool allow extending it using Java or Python so you can test virtually any system. Reporting is great: you can easily know which anomalous input caused an error to reproduce and fix it. **What do you dislike about Defensics?** The tool works best in case you're testing a protocol for which there's a built-in fuzzer. In case you choose to use a generic fuzzer like the Universal Fuzzer and add you're own logic then the usefulness of the tool is greatly reduced. Testing REST APIs which have good input validation (like JSON schema validation) won't typically yield much result. **Recommendations to others considering Defensics:** For basic testing you can rely on open source tools instead. I believe for world-class products a tool like Defensics is needed. **What problems is Defensics solving and how is that benefiting you?** Enhancing the robustness of our software. Defending against unknown attack vectors. Prevent SQL injections among other attacks. ## Defensics Discussions - [Where we can find documentation of each defensics protocol fuzzing ?](https://www.g2.com/discussions/11929-where-we-can-find-documentation-of-each-defensics-protocol-fuzzing) - 1 comment, 1 upvote - [View Defensics pricing details and edition comparison](https://www.g2.com/products/defensics/reviews?section=pricing&secure%5Bexpires_at%5D=2026-05-15+18%3A49%3A49+-0500&secure%5Bsession_id%5D=65f3d0ab-761b-4507-b8d7-680fa081a930&secure%5Btoken%5D=d658c79ce95066f1f3871a7b14a7c30ce2efa12f0f108d26084153f850338495&format=llm_user) ## Defensics Features **Administration** - API / Integrations - Extensibility - Reporting and Analytics **Analysis** - Issue Tracking - Reconnaissance - Vulnerability Scan **Testing** - Command-Line Tools - Manual Testing - Test Automation - Performance and Reliability ## Top Defensics Alternatives - [vPenTest](https://www.g2.com/products/vpentest/reviews) - 4.6/5.0 (229 reviews) - [Intruder](https://www.g2.com/products/intruder/reviews) - 4.8/5.0 (206 reviews) - [Astra Pentest](https://www.g2.com/products/astra-pentest/reviews) - 4.6/5.0 (185 reviews)
