They do a great job of figuring out the problem and pointing you to generic documentation or working with you to fine-tune a solution.

A chat service would be beneficial.
 

Scalability Issues

8.2
Check Point Harmony SASE is scalable, adaptable, and easy to deploy, benefiting both small-scale and large-scale dynamic operations.
Sentiment score
8.1
SentinelOne Singularity Complete is versatile, seamlessly expanding across platforms, integrating easily, but faces issues when scaling down.
I would rate it nine out of ten for scalability.
It's all auto-scale and auto-categorized, configuring automatically.
The tool's built-in automation for deploying the agents works well for large infrastructures like mine.
My deployment is relatively small, and SentinelOne Singularity Complete works within those constraints.
 

Stability Issues

Sentiment score
7.9
Check Point Harmony SASE provides stable, reliable access, excelling in diverse environments despite occasional issues under heavy loads.
Sentiment score
7.9
SentinelOne Singularity Complete is stable, reliable, with minor connectivity issues during updates; users appreciate its performance and stability.
There are some lags and glitches with connectivity, so I would rate the stability as between seven or eight out of ten.
After the last improvement, I can say it is much more stable now.
It has caused problems with interoperability between third-party tools, which could lead to entire servers crashing or specific tools failing.
This indicates room for improvement in stability when interacting with other solutions.
Initially, there were issues, particularly on the management side, but now the console is much more stable.
 

Room For Improvement

Check Point Harmony SASE needs more features, better documentation, improved speed, integrations, user interface customization, and competitive pricing.
SentinelOne Singularity Complete needs UI refinement, better automation, flexible policies, reduced resource use, and improved pricing and support.
A local data center in Turkey would enhance the product, as currently, our Internet traffic goes to another country, which is problematic for us.
The connectivity issue can be improved as at times it lags when connecting to their server.
The only thing that prevented the attack from succeeding was a free version of Malwarebytes.
Providing a single pane of visibility for the end user would be beneficial.
It's challenging to prevent a user from manipulating their privileges or someone else's of others, and it's difficult to control what users can access at the organizational level.
 

Setup Cost

Check Point Harmony SASE offers flexible, competitive pricing, but smaller companies may find minimum user licensing a challenge.
SentinelOne Singularity Complete is seen as cost-effective by some but pricey compared to traditional antivirus solutions, yet feature-rich.
Cost efficiency is a consideration, as SASE products are not the cheapest security products.
It is a bit expensive.
If you want protection, you have to pay the price.
They counted many of the instances and licenses as duplicates despite them only being alive once, which was frustrating.
It’s cheaper than other competitors.
 

Valuable Features

Check Point Harmony SASE provides secure connections with easy setup, advanced security features, and efficient management, enhancing user security and accessibility.
SentinelOne Singularity Complete offers robust, AI-driven security and seamless integration, enhancing performance and protection for enterprises.
The firewall management is the most valuable feature for me.
The best key features of Harmony are stabilization, private access, and Internet access.
I have an advanced app providing visibility of all my endpoints, which was not the case before.
SentinelOne has a feature to decommission automatically, which has been fantastic.
There's also automation that gives my team free time, preventing them from having to look for every alert.

Secure access with an intuitive design and straightforward controls
In terms of improvement, Perimeter 81 could enhance its reporting and analytics capabilities to provide more detailed insights into network activity. Additionally, expanding integration options with a broader range of third-party tools would be beneficial for seamless compatibility with various existing systems. As for additional features in the next release, it would be great to see advanced threat detection and response capabilities integrated into the platform. This would further enhance security by proactively identifying and mitigating potential threats. Additionally, improved mobile device management features and more comprehensive user behavior analytics would be valuable additions to meet evolving cybersecurity needs.
Asim Naeem - PeerSpot reviewer
It integrates well with other platforms, is user-friendly, and is stable
SentinelOne Singularity Complete integrates with our other security solutions, correlating data from NDR, ADR, SIEM, and XDR tools. All this information is consolidated within SentinelOne, providing a centralized access point. SentinelOne Singularity Complete has helped us streamline our security operations by consolidating multiple solutions into a single platform. We are currently in the process of acquiring a threat intelligence platform to complete our security stack. We use Ranger to monitor our network and track connected devices. This is crucial because it helps us quickly identify unauthorized machines connected to our infrastructure, including personal devices. We have additional security measures in place, but Ranger provides an extra layer of protection. It also alerts us if the SentinelOne Singularity Complete agent is missing from any new or existing machines, allowing us to take appropriate action. SentinelOne Ranger's agentless and hardware-independent nature is crucial for our environment with 26,000 endpoints, as manual management of such a large number would be extremely challenging. Ranger uses a multi-layered approach to prevent vulnerable devices from being compromised. We employ scanners, network configurations, and a risk scanner to assess devices, endpoints, servers, and cloud infrastructures. Vulnerability reports and timelines for remediation are shared with device owners or custodians. This proactive strategy enables us to address vulnerabilities efficiently and secure our infrastructure. SentinelOne Singularity Complete has significantly enhanced our security posture. While no system is impenetrable, this solution has brought us closer to achieving a high level of protection, ensuring we maintain at least a 90 percent security level. Our team is dedicated to refining alerts and eliminating false positives from our solutions. Additionally, a team is responsible for identifying and excluding alerts from the solution. We can manually expedite this process by reviewing these elements and utilizing our security tools. We have been able to reduce the alert volume by 20 percent. Our 30-member Security Operations Center team has been able to redirect their focus to other tasks due to the time saved after implementing SentinelOne Singularity Complete. SentinelOne Singularity Complete has helped us improve our mean time to detect threats, which we accomplish using the Vigilance service for detection and response. SentinelOne Singularity Complete has helped us decrease our organizational risk. We utilize the Security Scorecard to manage our security posture, which has remained steady at 90 percent.
