"Centralized Firewall Assurance Made Simple"

5/5

What do you like best about AlgoSec Horizon?

AlgoSec Firewall Analyzer is an excellent tool for ensuring firewall assurance against defined standards and compliance requirements. It provides a comprehensive, single-pane view of the entire network, making it easy to understand how policies are structured and what impact potential changes may have before they are implemented. This visibility is extremely valuable for maintaining a secure and well-organized firewall environment.

Additionally, the training offered by AlgoSec is very insightful and well-structured, making it especially helpful for first-time users. It provides a solid foundation for understanding the products and their capabilities, allowing teams to quickly become proficient in managing and analyzing firewall policies.

Overall, AlgoSec Firewall Analyzer is a powerful solution for improving network security posture and streamlining firewall management. Review collected by and hosted on G2.com.

What do you dislike about AlgoSec Horizon?

The initial configuration can be a bit complex and time-consuming, especially in environments with multiple vendors and large, distributed networks. Review collected by and hosted on G2.com.

What problems is AlgoSec Horizon solving and how is that benefiting you?

Managing complex firewall environments across multiple vendors can be challenging, especially when trying to maintain compliance, optimize policies, and prevent misconfigurations. Without clear visibility, it’s difficult to predict the impact of policy changes, which can lead to outages, compliance gaps, and security risks. AlgoSec solves this by providing a centralized view of all firewall policies, automating compliance checks, and continuously monitoring for risky or overly permissive rules. It simplifies audits by generating detailed, ready-to-use compliance reports and helps teams quickly identify and remediate violations, ensuring standards are consistently met.

AlgoSec’s policy impact simulation is especially valuable, as it shows exactly what will be affected before changes are made, reducing human error and avoiding downtime. This not only strengthens the organization’s overall security posture but also improves operational efficiency, saving time on troubleshooting and change management. With AlgoSec, firewall management becomes smarter, more secure, and more efficient, while giving teams the confidence that every change is both compliant and low-risk.

"Streamlined Firewall Setup with a Clear, Standardized Procedure"

5/5

What do you like best about AlgoSec Horizon?

What do you dislike about AlgoSec Horizon?

We have a complex network design and sometime it fails to understand how the traffic flows Review collected by and hosted on G2.com.

"Effective Firewall Cleanup with Algosec, but Needs Better Stability"

4/5

What do you like best about AlgoSec Horizon?

Algosec has proven to be a very effective tool for firewall cleanup activities, and I have been using it for this purpose for the past two years. The range of options and statistics it provides is quite good, though I have found that they are not always completely accurate. The monitoring features are also comprehensive, and I find the user interface to be especially user-friendly. Additionally, the tool is straightforward to deploy, which makes it even more convenient to use. Review collected by and hosted on G2.com.

What do you dislike about AlgoSec Horizon?

The main concerns I have with this tool are its occasional malfunctions and the fact that statistics are sometimes not visible. There are also communication problems with the Checkpoint firewall, as certain changes either do not appear in the tool or take a long time to show up. Even when our firewalls are configured identically, the tool still struggles to communicate with one of them. Additionally, there is a significant issue with integrating Microsoft Exchange Cloud relay, which we rely on for sending weekly firewall reports. This compatibility problem is a major drawback for the tool. The TAC support is not upto the mark as they don't have proper knowledge of the tool and they have very less senior TAC support members. Review collected by and hosted on G2.com.

What problems is AlgoSec Horizon solving and how is that benefiting you?

The primary advantage we gain from using Algosec is its support for firewall cleanup activities. Over the past two years, I have regularly performed these cleanups, and they have generally been completed successfully and without significant issues. Another benefit is the way Algosec documents each activity, which is helpful for referencing and verifying changes in the future. Review collected by and hosted on G2.com.
