Test Automation Specialist -Full Stack at IBM
Recording flows and script enhancements streamline performance testing, but script access limitations and outdated language hinder some functions
Apica allows me to record APIs easily and enhances scripts through options like auto-correlation, enabling me to access dynamic fields. The tool has a test analyzer for clear reporting and downloading PDF reports. It is useful for both performance and automation testing, facilitating access to headers and payloads easily, enhancing scripts with dynamic values.

Hands-on monitoring has built my threat detection skills and now supports my graduate research
The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge. I actually encountered an HTTP 500 error with the management interface recently, which required troubleshooting and expanding my storage, showing me how important storage planning and system maintenance are when running Security Onion. What I would improve about Security Onion is probably the documentation around troubleshooting common issues, particularly storage management, and making the interface more approachable for new users. Having documentation of what works best would help, especially since you can have nodes or have it all built-in one as a standalone. If you use nodes, you have to have several different Security Onion instances downloaded, then have a manager and connect all of them together.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Our application SREs do script checks in such a way that closely mimic our customers' actions using the platform. Because there are so many different ways and options to be able to configure checks to closely mirror your applications' capabilities, it provides a lot of optionality for teams to create the right type of check that can notify when there are any issues. At the end of the day, we want our monitoring tools to be able to catch any outage before our customers do. This is where Apica Synthetic does a great job."
"Apica is a complete package: You can monitor every single touch point that can fail inside a user's journey."
"The GUI is powerful and doesn't require scripting or regular expressions. It has a vast finder for correlation, which is easier than other tools like JMeter and LoadRunner. It's also easy to integrate with other tools with a separate execution environment. The tool is also easy to use."
"One of the biggest advantages of moving to Apica is the ability get to a hybrid model with the architecture in the cloud and our agents on-prem. We also have access to Apica's cloud agent across the globe. That has changed the way that we have our load testing setup at this point. Previously, it was always internal. Now, with this change in the way it is implemented for load testing, we can test anywhere across the globe and from the list of agents available within Apica's cloud. If I don't have an agent available in a second location, it just takes an email to their customer support, then it is spun up within 24 hours. That flexibility has changed the way that we perceive our load tests, not just in the US, but globally."
"It saves a lot of time by capturing and pinpointing the exact problem that is happening quickly."
"What I like the most is that Apica can simulate different browsers and different versions of desktop or mobile browsers."
"It is easy to set up and configure."
"The solution’s real-time monitoring features have had a huge impact on our service delivery."
"We use Security Onion for internal vulnerability assessment."
"Security Onion is the most mature solution in the market."
"What I appreciate most about Security Onion is that it combines multiple security monitoring tools into one platform."
"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."
"Security Onion has positively impacted my organization by enabling students to analyze logs, understand network traffic, comprehend intrusion detection, and utilize threat hunting and incident response skills in a practical environment, which are best practices we have implemented with the students."
"Security Onion brings these tools together in one platform, making it easier to investigate security events and understand what's happening across the network."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"Apica cannot perform endurance or scale-up tests independently."
"The having to install an application on your desktop to utilize something like ZebraTester is a little cumbersome. It would be nice to see that become a web-based application. Having the documentation a little more accessible, and easier to digest by people who are just learning how to use the framework, especially when it comes to more complex or more edge-based cases would be really helpful to have."
"The initial screen on their dashboard could have a bit more data, but this is a small thing. It could have more data, so we do not need to drill down to a screen behind that initial information. I would like them to get a little better on the user interfaces that we need to go into."
"Apica should add more features and integrations with different tools and certain ticketing systems, like ServiceNow."
"It is difficult to create a script using ZebraTester."
"Having to install an application on your desktop to utilize something like ZebraTester is a little cumbersome."
"The customer service and support were a little slow to respond. The browser sometimes checks alerts on unknown issues like latency from Apica's side."
"Apica is costly, and there's no way to test mobile applications through Apica."
"One of the improvements for Security Onion could be to address the issue of many logs and false positive alerts by reducing the number of false positives, as storage management is very hard sometimes due to a lack of storage space for logs, and they could implement methods to expand storage."
"Security Onion can be made easier to set up initially, as it is somewhat difficult at the start, but once configured, it becomes a great tool to use."
"The biggest challenges I have experienced with Security Onion are the learning curve and resource requirements, as it is not necessarily something you can install and immediately understand without networking and Linux knowledge."
"The product is not easy to learn."
"Security Onion's user interface could be improved."
"The initial setup of the solution is a little bit difficult."
"One way Security Onion could improve is by making the initial setup and configuration easier, especially for new users."
 

Pricing and Cost Advice

"The pricing is very reasonable, but it is not cheap."
"The tool is completely free and open source. I've been using it for about two and a half years and installed it on both my personal and client machines without needing a license. All features are available for use without any hidden fees."
"I know Apica is an expensive solution, but it is worth the money for the service it provides."
"The pricing and licensing are very reasonable. At the end of the day, you are using their technology/software and getting X amount of checks for a very decent value. As for discounts, they try to meet your budgets as much as they can. For example, if you need 100 checks and you have X amount of budget for it, then they will try and get down to that price. Costing-wise, it is a reasonably cost product. They will always try and come down to your price if you need them to come down to it by knocking off certain areas."
"The pricing is fair. It is neither too cheap nor too expensive."
"License management is another area that Apica could do better. We have already had these conversations with our account teams. This is something that they are looking at largely improving in upcoming releases. I believe that this is already on their roadmap."
"The product is less expensive compared to LoadRunner."
"The solution's pricing is not cheap, but it is in the midrange."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
"It is an open-source solution."
