Featured Reviews

Nasseer Qureshi - PeerSpot reviewer
Pre Sales Consultant at Redington Group
Delivers seamless and secure remote access while enhancing security posture
Check Point Harmony SASE (formerly Perimeter 81) offers strong features, but there are areas that could be improved. One area for improvement is integration with third-party identity providers. It works with standard SAML and SSO, but we would prefer deeper integrations with solutions such as Ping for more advanced identity-based policies. Additionally, a mobile-specific client or lightweight agent would be helpful for securing access from smartphones, especially in BYOD environments. We would appreciate more granular reporting and analytics, including better drill-down capabilities to investigate specific users or app activity. The logs are comprehensive, but filtering them can sometimes feel messy. The user interface on the management portal could be more intuitive, especially when managing multiple sites or remote offices. Some of the policy configuration steps are nested and could be streamlined.

A cloud solution to access the corporate network with BYOD policy
Ivanti Secure Access and Zscaler provide secure access to corporate networks, their methods and features may differ. Ivanti Secure Access offers granular control over network access, allowing for on-demand VPN connections when accessing corporate resources. This means users may not need to initiate a VPN connection manually but can access resources seamlessly when accessing corporate websites or applications. This granular feature helps enhance security and user experience by providing secure access only when needed.

Quotes from Members

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

Pros

"I appreciate the console of Check Point Harmony SASE (formerly Perimeter 81) because everything is well-centralized in one place."
"The Zero Trust and segmentation have helped my team and our customers significantly because we are able to protect every scope and allow the work-from-home users to access internal resources while passing through a threat prevention gateway, ensuring that everything is safe."
"Advanced behavior analysis and machine learning algorithms shut down malware before it does damage."
"The feature that I have found to be most valuable is the reputation that the company has regarding privacy. Nowadays, this is critical, especially when you do all of your work online."
"Harmony SASE helps us to manage compliance by regulating the amount of access to each department and user. We control the relevant apps and websites, which can be accessed from company-owned devices. Harmony SASE uses its own threat intelligence data from the cloud for threat prevention, and detect and manage threats with their own threat intelligence data and SASE firewall features."
"Customer service is excellent."
"The installation is very easy."
"Using the preboot VPN option, we can reset a user who is working remotely that has forgotten their Windows login credentials."
"It also provides an auto-connect feature. When you turn on your laptop and put it on auto-connect, it automatically connects."
"The most valuable feature of Pulse Client is integration with Google authenticator for two-factor authentication."
"Pulse Client is a very good solution; it is very easy to manage, and very stable."
"The scalability of Pulse Client is good."
 

Cons

"If Harmony SASE supported bidirectional traffic and the UDP protocol, it would be better."
"The integration from a management perspective could be improved so that the management can, from an existing Check Point firewall, manage a Harmony firewall through one pane of glass."
"There is a hefty cost"
"The main problem with Harmony Connect is that, because it's in a new category of offerings by Check Point, there's very little marketing of the product so far, and this means that many potential users don't even know this kind of solution is available. There are also few testimonials or case studies talking about people who have used the product and fell in love with it, for example."
"There is a very small amount of downtime."
"The Point locations need to improve the latency and speed."
"The platform's pricing can be an issue for smaller companies, as the cost may be higher than for larger organizations."
"The user interface on the management portal could be more intuitive, especially when managing multiple sites or remote offices."
"Pulse Client could improve the system tokens for authentication."
"Pulse Client could improve the reports. The reports are not in PDF and we can't check the details in the reports of users who are using the VPNs."
"Ivanti Secure Access and Zscaler provide secure access to corporate networks, their methods and features may differ."
 

Pricing and Cost Advice

"Overall I am very happy with the solution’s flexibility and pricing."
"Perimeter 81 charges separately for gateways and VPN connectivity, but compared to Azure, it seemed more reasonable."
"The pricing is good, especially when you compare it to other firewall or UTM solutions from FortiGate or SonicWall, where you would have to invest about four hundred thousand rupees for 100 users over a three-year period."
"Regarding pricing, I can say that the more the number of users, the less they have to pay."
"The cost of the solution's licenses depends on the particular use cases."
"I consider the product to be a medium-priced solution. There are no additional costs attached to the tool."
"Annual licenses cost $30 to $40 each."
"The product is reasonably priced."
"Pulse Client has two types of licenses. One is subsistence-based and the second is perpetual-based. The license cost is good, it is not very costly."
