Customer Service

Sentiment score

Sentiment score
5.3
Most users self-rely on forums; support, when used, is rated highly for responsiveness and quick, knowledgeable resolutions.
In a recent incident, I had an issue with the SharePoint API. It relates to documentation, specifically the lack of up-to-date documentation because Microsoft is moving away from the traditional SharePoint REST API to Microsoft Graph.
Prioritization of tasks can also be challenging, impacting the timely resolution of problems.
It was very good, and I would rate it an eight.
I have not dealt with support or customer service, however, the documentation is good, and I would rate it a seven out of ten.

The process was very efficient to scale the solution, which supports a high level of scalability.
It's not very easy to expand, and it would be beneficial if the process were simpler.
I would give OpenVPN a six out of ten for scalability, as it's usually a single user or single device.

OpenVPN Access Server Enterprise offers easy setup, strong encryption, scalability, multi-platform compatibility, and customization for secure remote access.
It's cost-effective by eliminating the need for firewall and networking equipment purchases.
The primary function of Azure VPN Gateway allows for designing subnets from existing networks, whether they are physical or virtual networks within Azure or other cloud instances.

Designs subnets with high security while navigating evolving integration processes
The primary function of Azure VPN Gateway allows for designing subnets from existing networks, whether they are physical or virtual networks within Azure or other cloud instances. You can configure these networks using IP numbers and connect them using certificates or SaaS strings. It also requires Entra ID for privileged access groups, resulting in high security.
Bertrand Moutault - PeerSpot reviewer
An easy-to-use tool with which its users can access networks from home or external locations
Sometimes OpenVPN Access Server is difficult to connect to, and in our company, we don't know why it is difficult. The product may not connect if we lose connection at times. There are certain shortcomings in the product's stability that need improvement. In general, I want to improve the connect connectivity of the solution since I sometimes face stability issues.
