Recording flows and script enhancements streamline performance testing, but script access limitations and outdated language hinder some functions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.

Centralized monitoring has strengthened threat detection and supports faster incident investigations
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 integrates well with our existing tools, primarily using Linux systems in our organization, allowing us to monitor logs and manage threat detection and operations in the public cloud effectively. Security Onion is very helpful in meeting compliance requirements and supports regular standards for our environment. I advise organizations that use Linux or have network security knowledge to consider Security Onion, as it satisfies requirements such as threat detection and log management systems. I would rate this review eight out of ten.

Quotes from Members

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

Pros

"Apica Synthetic is one of the most important monitoring tools that we're using because it's accurate, the support is the most responsive I've seen, it offers many integrations, is easy to set up and configure, the documentation is great, and most importantly it has helped reduce the time needed to resolve issues and outages."
"It helps with releases because we monitor them in staging. We can tell if something is critically wrong before it gets into production, e.g., if it was load related or function related and also what was different in the dev stage. It then alerts us straightaway inside of our production monitors once it has been released. Therefore, it has improved how we run our systems since we monitor multiple environments."
"It saves a lot of time by capturing and pinpointing the exact problem that is happening quickly."
"It is easy for beginners to learn and use Apica."
"It uses a basic scripting language, which is easy to learn and customize as needed. Compared to LoadRunner, I found writing and customizing code much easier in Apica."
"From my perspective, I would say it has saved us costs involved in monitoring; it's enabled my resources to work more focused, more accurately, more authoritatively, and more adeptly, and from an operational standpoint, I would say that it's at least improved our monitoring efficiency by 5% to 10%."
"The solution’s real-time monitoring features have had a huge impact on our service delivery."
"You can tell from the operational space of people who are using and consuming this data that they are more integrated. It is not dependent on one team anymore. It saves a lot of time by capturing and pinpointing the exact problem that is happening quickly. We have moved from getting escalations manually to getting escalations synthetically."
"We use Security Onion for internal vulnerability assessment."
"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 is the most mature solution in the market."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
 

Cons

"Learning the tool has always been a little difficult from a scripting perspective because the framework is proprietary and unique."
"The reporting part that we use for our executives needs a bit more customization capabilities. Right now, you can use only the three main templates for reporting. We would like to be able to customize them."
"The accuracy of alerts can be improved a little bit; what we have seen happen is the number of alerts that we are getting is very frequent, and we would like to tone down the number of alerts."
"There are some components of the user interface that are not up to date. Just to give you an idea, today we have web applications that are called single-page applications that are much faster than the old style of web application. If we can move faster into the flow of the graphic user interface, and in a more effective way, it will save us a lot of time."
"I have noticed that the tool isn't widely recognized outside our organization. Also, there aren't any tutorials or dedicated resources for this tool, making it challenging for newcomers to learn. It would be beneficial if someone experienced with it could provide guidance."
"Apica was a relatively new tool when I started using it. Although Apica had good documentation, it still felt less developed or advanced than a tool like LoadRunner."
"Apica should add more features and integrations with different tools and certain ticketing systems, like ServiceNow."
"Having to install an application on your desktop to utilize something like ZebraTester is a little cumbersome."
"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."
"Security Onion's user interface could be improved."
"The product is not easy to learn."
"The initial setup of the solution is a little bit difficult."
 

Pricing and Cost Advice

"I know Apica is an expensive solution, but it is worth the money for the service it provides."
"The level of alerting accuracy has saved us time and money in operational costs. Overall, it has automated a lot of the manual efforts which have been more complex with some of our other scripting tools or monitors. So, it brings things together by doing things faster and saves us money."
"The pricing is very reasonable, but it is not cheap."
"Apica is pretty cost-effective if you buy both solutions together: Synthetic and LoadTest. If you are going for one solution, the cost is on par with any tool in the market."
"Another main difference between Apica and the other products was the cost. We really thought that the balance in Apica between the features and costs was the best among all the products on which we did a PoC."
"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."
"The solution's pricing is not cheap, but it is in the midrange."
"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."
"It is an open-source solution."
"Security Onion is a free solution."
"Security Onion is an open-source solution."
