Ranorex Studio

PFLB

Functional testing and load testing for 10/25/40Gbps line rate traffic.

Ostinato

Linux

Windows

Sr. Controls Eng.

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

Principal

Ease of use, mature gui and the ability to craft packets as well as use pre loaded or saved traffic sessions.

network engineer

Perfect solution for network testing under virtualized envirnment like GNS3 and EVE-NG.

Sr NetEng

In other words, to identify if packet loss is verified and when such bottleneck can be host based.

Sales Engineer

Very happy with its capabilities, great value for the price.

consulting engineer

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

Software Consultant

There is nothing about Ostinato that has disappointed me yet.

Not have prebuilt packets for common protocols is a bummer some times.

SW Engineer

It also has other cool features such as the ability to export a given configuration to a python source file. This allows for quick logic prototyping and testing.

Great tool to have to complement your enterprise network support systems.

Global Director of Technology Alliances

It sometimes requires a lot of manipulation to get the attack to register on the security tool.

It provides a comprehensive API that can be easily incorporated into an existing test environment. The Ostinato GUI makes it easy to replay existing network captures (.pcap files) to exercise a DUT.

Senior NEtwork Engineer

I liked the way we can integrate Ostinato into the network or lab and the capacity of protocols we can test.

Instructor

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.

The Industry Standard Traffic Generator

Thank you for your thoughtful review! We're glad to hear that you find Ostinato to be a valuable and flexible traffic generator.

We appreciate your feedback on the UI/UX and will reach out to understand the challenges you've faced. Your insights will help us improve the user experience, and we'd love to see how we can address any difficulties.

Thanks again for your support!

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.

Fast and objective

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!

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

Generator not tester

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)

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!

We've had numerous success stories with Ostinato

Thank you Chintaharan for your effusive praise!

We are absolutely delighted has Ostinato has enabled many success stories for you and your organization!

Do reach out to us if you have suggestions for newer use cases - we will definitely consider them!

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

Excellent protocol analyzer

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?

Overall I am a satisfied user who uses patina to for throughput test on edge devices

Simple and Fast TG

Thank you Mohit!

Would love to know more about the protocol specific and topology specific traffic scenarios that you would like added to Ostinato so that we can add it to our roadmap - please reach out to us!

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.

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

Thank you for your kind words, Chris!
I'm sure your review will encourage more network engineers try Ostinato and benefit from it.

I have experience doing performance test on Network devices. Ostinato allow me to generate traffic with specific metric.

Thanks to this i able to identify, which device is more suitable for our environment.

Senior Network Engineer

Thank you for your review, Hafiz!

We are sorry you didn't have a great support experience and are not very likely to recommend Ostinato to others.

We'd like to make amends and improve your Ostinato experience - please do reach out to us

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

Ostinato is a great tool!

Thank you Philippe! Please do share the aspects of the GUI that you find non-intuitive - we will try and improve the same!

Excellent valuable software to use. Real Swiss knife tool.

Must have tool for traffic analisys

Thank you for your kind words Vitor! "Swiss Knife" is apt!

It is my go to product for packet crafting for security/FW testing, network load and fail over stimuli testing. Application simulation for performance. I have used this product almost ten years. It has matured greatly and if its result data can be tied into analytics/splunk/AI type systems vai api pipeline an AI system can take the traffic load/impact results from Ostinato and provide additional analysis feedback.

Great tool to have to complement your enterprise network support systems

Thank you for your kind words Jeff!
Your suggestion of integration with analytics/splunk/AI systems is a good one!

It is a great tool to automate my traffic tests

Great tool for automating

Thank you Jose!

We are happy to hear your automation success with Ostinato. We have taken your feedback about the UI and will work on improving it in future versions.

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.

A good product that fit your neeeds

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!

It was great working with [sensitive content hidden], he is always quick to answer emails and improve his product. 

When iPerf just doesn't do it anymore...

Very good.Would love to know if there's any way (present or future) to leverage a CLI-based ostinato.I.e. a CLI command in linux that would do the same as the "generate" click in the GUI.Example (new command called "ostinato-send", etc.)ostinato-send <stream> <interface>etc.

Fine product.  Replicates customer issues very well.

Thanks Scott for for your review! We will try to explain the various concepts and the relationships better. Regarding the CLI, you can do this easily using the Ostinato API - please reach out to Ostinato support and we'll help you out!


Excellent alternative to expensive network performance testing tools

Thanks for your kind words, Peter! We'll try and extend the GUI to remember the last column size settings for the ports window.

Very functional software for testing various features of networking equipment

Thank you Yavor!
We will try to make the GUI more intuitive and user-friendly

Help with Homologation and Certification

Thanks for your review, Matheus! If there are any missing features that you would like to see in Ostinato, do let us know!

Great quick support. I would not hesitate to recommend it to anyone that wants to perform throughput testing

Excellent solution to test throughput perfromance

Thanks Andre! Yes, the UI is a bit dated but functional, so at the moment we prefer to work on new features than completely redo the UI.

You can try setting a different theme for the UI - https://www.youtube.com/watch?v=IQc6xa2Rc9Q

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.

We use Ostinato in generating traffic in our firewall testing.

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.

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. 

Must have tool

Thank you for your kind words, Aharon!

Please let support know about what new protocols you would like to see and we will add it to out roadmap!

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.     

Teaching Packet Crafting to Teens

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

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. 

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

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.

Outstanding - it is accessible and user friendly - simple - and helps young students learn - keepUp the great work 

Ostinato in Schools

Thank you Graham for your kind words! We are happy to see Ostinato helping to train the next generation of network engineers!

I use the product to test functionality and it has worked perfectly for the goal

Great value for the dollar

The upcoming v1.3 will allow user editable port descriptions (see https://twitter.com/pstavirs/status/1568183077662490624). Please share your use case for reordering ports and we will consider implementing!
