Customer Service

Sentiment score
6.1
Digital Guardian customer support efficiency varies; users praise global help but note inconsistency in response time and technical understanding.
Sentiment score
4.9
Zscaler's support is praised for knowledge and responsiveness but varies in resolution time and regional quality.
For vendor support, such as Fortra support, I would rate it a seven because all the support comes from different parts that sometimes have challenges meeting time zones, and sometimes they reroute to distributors and rely on partners.
Cyber Security Researcher at a tech services company with 11-50 employees
The support engineers are technically knowledgeable, particularly for Zscaler Private Access related issues, providing clear guidance and documentation for troubleshooting.

The only limitation I was mentioning is that it was unable to identify the sources of vulnerability, which they are going to embed by the mid of this year.

Room For Improvement

Digital Guardian needs to enhance partner programs, policy simplicity, cross-platform features, resource efficiency, cloud integration, and technical support.
Zscaler's platform needs latency and usability improvements, better multi-tenancy and support, clearer pricing, and enhanced SIEM integration.
The issue is that it works only with users or companies with more than 500 users.
Cyber Security Researcher at a tech services company with 11-50 employees
Digital Guardian can generate false positives initially, which can be significantly reduced through proper policy tuning and data classification.

It would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views.
Technical Team Lead - Content Security at Valuepoint Systems
Zscaler Zero Trust Exchange Platform probably needs to be more efficient because scanning takes a lot of time.

Digital Guardian is costly but ideal for enterprises needing strong data loss prevention, especially in manufacturing.
Zscaler Zero Trust Exchange Platform has high subscription costs but offers ROI by reducing infrastructure needs and enhancing security.
There is minimal setup cost since it is a cloud-delivered platform, eliminating the need to invest in additional hardware such as VPN gateways or maintain infrastructure.
Technical Team Lead - Content Security at Valuepoint Systems
Zscaler Zero Trust Exchange Platform is much, much cheaper when comparing price.

Featured Reviews

Syed Mubeen - PeerSpot reviewer
Cyber Security Researcher at a tech services company with 11-50 employees
Enterprise data protection has supported regulatory compliance and integrates with classification tools
In terms of functionality, many features are valuable in Digital Guardian, as the first thing for most customers is that they are using solutions such as Boldon James and Titus, which fall under the classification side, and Digital Guardian can easily integrate with this data classification solution and has a very granular level of configuration and policy tuning. Digital Guardian's data protection policies are indeed useful for my clients. Regarding Digital Guardian, I find it to be a very good solution, and in fact, it is an enterprise-level solution that has very tight integration with most of the products, with Fortra but also with others.
Vibin Thomas - PeerSpot reviewer
Technical Team Lead - Content Security at Valuepoint Systems
Zero trust access has transformed remote connectivity and now simplifies secure app usage
Zscaler Zero Trust Exchange Platform, especially Zscaler Private Access, is very strong, though there are a few areas where improvements can be made. One challenge observed is around initial troubleshooting and visibility. While Zscaler Private Access provides logs, it can sometimes take time to pinpoint the exact cause of access issues, especially in complex environments with multiple policies and identity integration. Another area is the dependency on identity and connector health. Since Zscaler Private Access is heavily reliant on app connectors and identity providers, any issues with these components can impact user access, making proper monitoring critical. During the initial setup, policy configuration and application onboarding require careful planning, especially for larger environments with many applications. These challenges are manageable with proper design and monitoring. Overall, the platform delivers strong security and user experience. I would recommend a few improvements, especially around user interface, reporting, and troubleshooting experience. From a user interface perspective, while the platform is powerful, the policy configuration and navigation can feel complex, especially for new users. A more simplified and intuitive layout for policy mapping and application access would help reduce the learning curve. In terms of reporting, Zscaler Private Access provides logs, but having more built-in customizable dashboards and analytics would be very helpful. Better visibility into user access patterns, application performance, and real-time troubleshooting insights would improve operational efficiency. From a support and troubleshooting standpoint, it would be beneficial to have more granular centralized visibility, allowing for quick end-to-end tracing of a user request from authentication to application access without switching between multiple views. These improvements would make the platform even more efficient, especially for large-scale enterprise environments.
