ROI

6.0
Kaseya VSA improved efficiency and remote support, offering significant ROI despite some disruptions, especially post-COVID-19 for IT providers.
Sentiment score

Zabbix, free and open-source, reduces downtime and costs, improving network stability and significant enterprise savings.
 

Customer Service

Sentiment score

Kaseya VSA's customer service is responsive but often slow, inconsistent, and sometimes requires escalation for issue resolution.
Sentiment score
6.8
Zabbix users praise supportive documentation, community forums, and responsive technical support despite occasional time zone challenges and free version reliance.
The customer service provides a fast response.
I would rate their support five out of ten because most of the time they are not able to resolve the issues.
It is so straightforward that I have never had to use the support.
 

Scalability Issues

Sentiment score
6.9
Kaseya VSA is scalable and flexible for diverse business sizes, despite performance lags and past security challenges.
Sentiment score
6.9
Zabbix is highly scalable, excels in diverse environments, but large deployments may require database optimization for efficient performance.
Zabbix has high scalability.
Zabbix is very scalable and lightweight.
I would rate its scalability ten out of ten.
 

Stability Issues

Sentiment score

Kaseya VSA is stable with occasional issues in performance, patching, and support but generally rated reliable by users.
Sentiment score
7.5
Zabbix is reliable and resource-efficient, performing well with database tuning and handling heavy workloads without crashing.
Zabbix is very scalable and lightweight.
Zabbix is quite stable, and we haven't had any problems with Zabbix itself.
 

Room For Improvement

Kaseya VSA needs UI improvements, better patch management, security measures, enhanced support, and more customizable reporting features.
Zabbix users seek improved UI, automation, integration, and customization with enhanced reporting, security, and scalability for non-technical users.
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
 

Setup Cost

Kaseya VSA offers competitive, region-based pricing with discounts, favorably compared to competitors but varies in cost with scalability options.
Zabbix is cost-effective and flexible, offering open-source monitoring with no licensing fees, low expenses, and optional support costs.
It's always expensive for the customer.
 

Valuable Features

Kaseya VSA provides remote access, patch management, and security features with expanded support for phones and tablets, enhancing usability.
Zabbix is valued for open-source customization, scalability, comprehensive monitoring, alerting systems, and cost-effective enterprise IT management.
Regarding the patching and software management, for me, it's the best path.
If disk usage surpasses a threshold, say 70%, I receive alerts and can take proactive action.
Zabbix is Linux-based open-source software, and the main use case is to reduce costs.
Zabbix has a lot of features, including monitoring, status updates, and collecting information telemetry from storages and servers as well.
