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's support is generally praised for expertise but criticized for inconsistent response times and escalation processes.
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.

Sometimes, support takes time since the solution has some bugs that need fixing.

Featured Reviews

Syed Mubeen - PeerSpot reviewer
IT Manager 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.

Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.
