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Recording flows and script enhancements streamline performance testing, but script access limitations and outdated language hinder some functions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

Centralized threat monitoring has improved visibility but demands complex setup and configuration
The best features Security Onion offers include acting as the intrusion detection system in my organization and helping me to address traffic, logs, and events happening within the organization. Since Security Onion is an open-source system that integrates with tools like Suricata and Zeek with the ELK stack, it enables threat detection and response capabilities, delivering high-level security measures at a cost, making it suitable for businesses of varying skill levels. These integrations with Suricata and Zeek have greatly impacted our workflow and our team's effectiveness by helping us address issues such as identifying intrusions, evaluating threats, and overseeing log files. This tool is very cost-effective, making it suitable for any size of organization wanting to use it.

Quotes from Members

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

Pros

"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 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."
"Apica is a complete package: You can monitor every single touch point that can fail inside a user's journey."
"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."
"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."
"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."
"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."
"Security Onion is the most mature solution in the market."
"Security Onion has positively impacted my organization by greatly improving our security posture, making alert triage easier to handle, simplifying the analysis of threats, and decreasing the cost of threat analysis and detection."
"The most valuable feature of Security Onion for security monitoring is its ability to find infected ports."
"Security Onion is a completely open-source and free platform, making it a cost-effective solution that works smoothly and effectively for our organization."
"We use Security Onion for internal vulnerability assessment."
 

Cons

"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."
"When it comes to the way the internal agent is installed, because you can install an application on a server, I would love to see the application Docker-ized. If you could install internal agents using Docker or using containers, it would be easier for us to manage them and spin up internal agents."
"Learning the tool has always been a little difficult from a scripting perspective because the framework is proprietary and unique."
"We have been focused on reducing polling times for synthetic checks. We have gone from 10 minutes down to five minutes for a pretty broad swath, but there is some appetite to reduce that further, which could be an improvement."
"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."
"Check frequency has been a scalability challenge for them."
"The tool does not provide automatic correlation features."
"Having to install an application on your desktop to utilize something like ZebraTester is a little cumbersome."
"The initial setup of the solution is a little bit difficult."
"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 product is not easy to learn."
"Security Onion's user interface could be improved."
"For Security Onion, setting up and configuring the system can be quite challenging for newcomers due to the need for a grasp of networking and security concepts."
 

Pricing and Cost Advice

"The pricing is fair. It is neither too cheap nor too expensive."
"The pricing is very reasonable, but it is not cheap."
"I know Apica is an expensive solution, but it is worth the money for the service it provides."
"I am sure that Apica's price will be lower than LoadRunner."
"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 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 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 solution's pricing is not cheap, but it is in the midrange."
"It is an open-source solution."
"Security Onion is an open-source solution."
"Security Onion is a free solution."
