### "Ostinato - Best tool available for network troubleshooting"

October 30, 2025

5.0

We loved the product. We used it to help harden our network and to troubleshoot various bandwidth capacity issues. I would highly recommend it to other engineers trying to support their networks.

Pros

Ostinato is an awesome tool used to generate traffic and study it's affect on your network - both in type of traffic and in quantity of traffic. It was easy to use and has a plethora of documentation that can help with use cases.

Cons

Ostinato can seem a little like overkill for simple situations. If you want to just "plug and pray" and you don't know what you are doing it can seem overwhelming the amount of choices you have to the interface.

### "Great tool"

March 27, 2026

5.0

Pros

It’s flexibility and ability to be used in various operating systems, the configuration options are also top notch

Cons

The extensive configuration options can have a steep learning curve for new users getting started But that’s it.

### "Generator not tester"

September 29, 2021

2.0

Only suitable for laboratory use. It has the potential but lack of network tester functionality disqualifies it from everyday use.

Pros

Platform Availability (Linux, Masons etc)

Cons

Difficult to use, no network tester function.

Review Source

October 1, 2021

Thank you for your feedback! Can you elaborate on what network tester functionality you are looking for so that we can consider implementing that in a future release? Srivats (Founder, Ostinato)

### "Fast and objective"

September 30, 2024

5.0

We had a problem with a poorly configured DNS server in the environment that was generating several conflicts and unavailability of critical applications. In less than 15 minutes I was able to identify the source of the problem.

Pros

The quick and objective way to find and help solve problems

Cons

The price could be more affordable and a free version for home use

Review Source

Response from Ostinato

October 17, 2024

Thank you for your feedback, Gilberto! Happy to hear you were able to diagnose your network problems to a faulty DNS server - ain't DNS (almost) always the culprit?! :-) Regarding the price, we are a small team trying to provide a quality product and customer service with limited resources. At the current stage of the company we are not in a position to reduce the price or provide a free version. We will reconsider this as we grow!

### "Using Ostinato as a Load Generator Server on high speed network"

October 31, 2025

5.0

The tool is great and did what we needed for our project. Client was impressed at the capabilities of it. Part of my learning curve was building a custom system of my own so no fault to the developer!

Pros

Completely customizable (as it should be) since you can build out a load test server using retail off-the-shelf components.

Cons

Support is highly recommended to purchase, due to complexity of setup in order to tune your system to achieve maximum output with Turbo license add on. But the developer was super helpful so not a negative experience. Custom prebuilt recommended systems would help here.

Hi Srivats, I wanted to take a moment to congratulate you and your team on developing such an incredible tool. We've had numerous success stories with Ostinato, conducting several POCs and FATs that have allowed us to effectively showcase test cases to our clients. The tool is not only lightweight and user-friendly, but it also makes demonstrating and verifying outputs so much easier. I’m truly grateful for how it has contributed to the success of many of my projects. Thank you for your hard work!

September 26, 2024

5.0

Excellent, I love that you can capture and inyect messages, an indispensable tool

Pros

All the information available, and known protocols

Cons

Sometimes can be overwhelming amount of data to filter an go thru, maybe more intuitive filtering could help

Review Source

Response from Ostinato

October 17, 2024

Thank you, Alfredo! Do you mean to create a packet/stream one has to fill a lot of data? Can you give an example of intuitive filtering so that we better understand your suggestion?

### "What's in your network wallet...? Hopefully Ostinato"

September 26, 2024

4.0

I'm a network engineer of 25+ years. This is exactly the sort of tool to have in your pocket when you need to prove behaviors of network traffic.

Pros

I liked the simplicity and layout of the application

Cons

updating myself to the latest version. I have a very old copy. The changes however, were both timely and necessary

Review Source

Response from Ostinato

October 17, 2024

### "+10y in and still so relevant !"

March 30, 2023

5.0

Pros

This traffic gen has been a life saver in multiple occasions. Working for a VAR and having multiple projects all with different traffic profiles, Ostinato is versatile enough to be able to generate or even replicate production like traffic to identify problems in a network setup.

Cons

End to end traffic analysis complement could be useful - to understand if what is sent is aligned to what is received. In other words, to identify if packet loss is verified and when such bottleneck can be host based.

Response from Ostinato

April 12, 2023

Glad that Ostinato is a "life saver"! We will reach out to you to understand more about what kind of end to end traffic analysis features you would like to see and add it to our roadmap.

March 22, 2023

5.0

Pros

being able to build packets for testing a network on how it will behave is a absolute godsend.

Cons

Not have prebuilt packets for common protocols is a bummer some times. Would be nice for fast spin ups.

September 18, 2024

Overall, Ostinato delivers great value and is a key tool for our devices QA testing.

Pros

It is very easy to create traffic scenarios in order to test a networking device. The paradigm of drones and GUI connecting to drone is simple and works very well.

It is a great tool to automate my traffic tests

Pros

By using it, it really helped automating my test

### "A good product that fit your neeeds"

September 17, 2024

5.0

My experience was great. By beginning I needed to review several documentation to achieve my scenario but once I hit what I needed worked like a charm. Very reliable and results as expected.

Pros

You can achieve tests with simplicity and ease to use

Cons

The interface could bring more of not just specifics but something like click here to start and move on to advanced settings

October 17, 2024

Thank you Sidnei! We will consider how to simplify the UI to make common use cases easier and faster to set up - as you say one-click!

### "An outstanding platform for performance testing that rivals high-end hardware solutions"

March 22, 2023

5.0

I have worked for a few companies now and it is very hard to justify a performance tester outside of QA and Dev so to have an affordable option that works allows me to take Alliance Partner acceptance testing to the next level rather than trying to rely on tcpreplay or Dev to let me use theirs.

Pros

1\. Ease of use2. Multiple deployment options3. Flexibility to customize screens4. Import of existing PCAP files5. Granular control of steams

Cons

The one drawback is that a lot of my testing with our security alliance partners require the use of specific pcaps, I leverage, https://www.malware-traffic-analysis.net/, for the much of this. It sometimes requires a lot of manipulation to get the attack to register on the security tool. May just be a training issue so a whitepaper etc on this would be great.

Reason for choosing Ostinato

Cost and limited deployment options with a single appliance.

Review Source

Response from Ostinato

March 28, 2023

Thank you James for your kind words. Regarding the malware pcap replay not registering on the security tool, please reach out to the forum or support. We will try and help you out.

March 30, 2023

5.0

This is the must have software for any user who needs to simulate/test network equipment and can not use real traffic generator like IXIA or SmartBits. For example, when working from home office.

Pros

I really like the look and feel of real traffic generator.

Cons

I miss support for some kinds of protocols, like PTP for example.

### "Teaching Packet Crafting to Teens"

March 29, 2023

5.0

Ostinato is a great teaching tool for both networking and security. It allows me to create customized challenges (packets and traffic) and let the students figure out the solutions. This also means there are often more than one way to solve a problem thanks to the way Ostinato break apart packets and traffic. All students know Wireshark but now they know how to manipulate packets and traffic on their own. This lets me dive into forensics as well. Ostinato is not a forensic tool but it does allow an investigator the ability to see traffic, trace traffic, evaluate each packet, dissect those packets, and develop a plan for evidence collection. This is a much needed tool for any network analysis.

Pros

Teaching teens means they ask a lot of questions. Ostinato is well documented and provides an answer to just about every question that come up. The best part is that I can show the students how we get to that answer. This also allows me to bring up additional questions for the class and let them discover the answers on their own. All the teens know TCP and UDP. I like to have them dig into other protocols to discover how each are different (frames, size, data) and Ostinato allows me to assign new concepts and let the students play with them on their own.

Cons

There is a bit of a learning curve but nothing that can't be overcome as you learn how packets and Ostinato work together.

Response from Ostinato

Very happy to see that Ostinato is helping educate the next generation of network and security engineers!

### "We use Ostinato in generating traffic in our firewall testing."

March 31, 2023

5.0

As mentioned before, the overall experience with Ostinato is satisfied. We meet our goals in the network security testing using Ostinato to simulate various types of crafted traffic we were planning to test.

Pros

Ostinato provides us a handy tool to generate traffic that we are using to pass on into the testing firewall stack. It has a lot of options to craft the traffic and control the behavior instead of bringing in a lot of end devices which is not practical in our lab environment. The feature we used most is to rerun the recorded traffic from the production which save us a lot of time.

Cons

We had a lot of difficulties in running the Linux VM. If this small VM can get improved, it will be most helpful. We tried to build a mobile test pod by using R-Pi in order to perform our test out of the lab environment, out in the field test. But it was not working quite well as we expect.

Reason for choosing Ostinato

Ostinato is recommended from one of our colleagues who used it before.

Review Source

Response from Ostinato

April 12, 2023

Happy to hear that Ostinato is helping with your firewall testing, Sira! We will reach out to you about your difficulties with the VM and look into how we can improve it.
