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

"Our investment in quality hardware has proven to provide a better customer experience. They heavily rely on Check Point Firewall and Check Point SaaS Connect to safeguard their networks from external threats and attacks."
"I find it very easy to implement and deploy in the organization."
"The features are excellent, particularly the user interface and user accessibility."
"It's improved the security of every single OS in the organization as well as the visibility and security capabilities."
"SD-WAN is one of the primary solutions offered by Perimeter 81."
"Harmony Endpoint gives us a complete security package with a lot of security features that regularly require a lot of separate security products and a lot of overhead management."
"Advanced behavior analysis and machine learning algorithms shut down malware before it does damage."
"The best key features of Harmony are stabilization, private access, and Internet access."
"The most valuable feature of Pulse Client is integration with Google authenticator for two-factor authentication."
"The scalability of Pulse Client is good."
"It also provides an auto-connect feature. When you turn on your laptop and put it on auto-connect, it automatically connects."
"Pulse Client is a very good solution; it is very easy to manage, and very stable."
 

Cons

"There is a very small amount of downtime."
"I have found that the log-in/out process takes quite some time."
"Sometimes downloading PDF files can be slow."
"If Harmony SASE supported bidirectional traffic and the UDP protocol, it would be better."
"If I were to be nitpicky, I would ask that Perimeter 81 offer the option for us to change the color of the graphical user interface, like maybe pink or green or so on."
"They should work towards the WAN intergration."
"The access to the portal should be faster. It shouldn't crash a lot."
"One of the more negative experiences using Perimeter 81 is the fact that I am logged off after a pre-determined amount of time which cuts off access to some of my company's resources."
"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."
"Pulse Client could improve the system tokens for authentication."
 

Pricing and Cost Advice

"The product is reasonably priced."
"The pricing of Check Point is relatively high when compared to other competitors like Palo Alto and Fortinet. While Palo Alto may be on the higher side in terms of cost, Check Point's pricing is similar to that of Fortinet. In some cases, Check Point offers better value for the features it provides. We initially considered other options but ultimately decided to purchase hardware that came with three years of iOS. This approach eliminated the need for any additional costs associated with Check Point. I would rate it 10 out of 10."
"I would rate Harmony Connect's pricing at six out of ten. It wasn't particularly expensive, but it wasn't super cheap either."
"I consider the product to be a medium-priced solution. There are no additional costs attached to the tool."
"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."
"Annual licenses cost $30 to $40 each."
"The solution's pricing model may not be suitable for smaller companies, as they might find it expensive. Larger companies tend to receive more value due to many users."
"Perimeter 81 charges separately for gateways and VPN connectivity, but compared to Azure, it seemed more reasonable."
"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."
