ROI

Sentiment score
5.8
Digital Guardian improved data protection, reduced breach risks, ensured compliance, saved money, and enhanced security and operational efficiency.
Sentiment score
7.1
Zscaler Zero Trust Exchange Platform provides cost-effective security, enhancing visibility and stability, and outperforms previous setups like Fortinet.
When I see that I am trying to cut costs, for example, even when replacing Prisma, we have managed to save about over half a million dollars a year.

We don't have to purchase many components such as load balancers and proxy servers that were necessary in traditional setups.

Customer Service

Sentiment score
6.7
Digital Guardian's customer service is prompt but can be inconsistent, especially for complex issues or international clients.
Sentiment score
4.8
Zscaler Zero Trust Exchange Platform support is reliable with regional availability, receiving ratings 8-9, despite occasional delays.
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.

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.

Secure access has improved remote work and has reduced vulnerabilities across our workforce
Zscaler Zero Trust Exchange Platform probably needs to be more efficient because scanning takes a lot of time. Some vulnerabilities create issues, and when we wanted to identify the source of the vulnerabilities, specifically focusing on mobile ID and related areas, it was unable to provide assistance. However, according to discussions with Zscaler Zero Trust Exchange Platform, they said that by the end of mid-2026, they are exploring these features, and probably those features can be incorporated or embedded into this particular system. That is the only major negative point.In terms of responses, Zscaler Zero Trust Exchange Platform is good. In terms of controlling vulnerability, it is good. The only cons I have noticed is that it is a bit slower, and sometimes it is unable to identify the source. These are the key areas for improvement.
