Room For Improvement

Check Point Harmony SASE needs improvements in performance, user interface, integration, documentation, scalability, and features like SD-WAN and firewalls.

Deep Instinct needs improved control, compatibility, logging, resource efficiency, and competitive pricing for better usability and performance.

A local data center in Turkey would enhance the product, as currently, our Internet traffic goes to another country, which is problematic for us.

Emir Sozer

Technical Lead at Netsmart

One area for improvement is integration with third-party identity providers.

Pre Sales Consultant at Redington Group

The product is lacking features that other competitors have, making it quite challenging to migrate customers to this solution because it feels very much unfinished.

Deep Instinct Prevention Platform detects malicious scripts but it needs better measures, perhaps signing scripts, so we can be sure that a script is created by a client, not by some malware.

Setup Cost

Check Point Harmony SASE offers competitive value for large enterprises, though its pricing isn't the cheapest for smaller firms.

Deep Instinct offers competitively priced, efficient enterprise protection with nonprofit discounts, simple licensing, and included support, despite console cost concerns.

Cost efficiency is a consideration, as SASE products are not the cheapest security products.

The cost is a bit expensive for most users.

Valuable Features

Check Point Harmony SASE offers secure, efficient, and centralized network management with real-time threat intelligence and zero trust access.

Deep Instinct offers accurate, lightweight malware protection with real-time, offline capabilities and seamless deployment across Windows, Mac, and Android.

The firewall management is the most valuable feature for me.

The Zero Trust Network Access (ZTNA) feature is a major highlight as it gives users seamless and secure access to internal resources without requiring a full-blown VPN, which improves both security and user experience.

Pre Sales Consultant at Redington Group

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.

Delivers seamless and secure remote access while enhancing security posture

Pre Sales Consultant at Redington Group

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.

Stops ransomware before it executes and reduces response time for the team

CTO at Klaatu IT Security Ltd

A potential area of improvement for Deep Instinct Prevention Platform is their focus on file uploads and large data storage, backups, and other related areas. It is difficult to think of what they could improve, but low information provided by the system when it detects something is one area, particularly in scripting. Deep Instinct Prevention Platform detects malicious scripts but it needs better measures, perhaps signing scripts, so we can be sure that a script is created by a client, not by some malware. It is really about helping us triage incidents effectively, so a bit more help with the analysis of incidents, particularly what the Deep Instinct Prevention Platform agent has discovered, would be beneficial. We need to know what it has spotted that makes it suspect malware.
