“We did not get the level of service that we paid for”

We purchased an expensive option to have AT&T provide us with "white glove" installation and configuration services. The selling point for that was, they would be able to get us up and running in one week. It has been three months and we're still making configuration changes.

AT&T Managed Security Services, Worldwide Likes & Dislikes

Like

I liked how easy the system was to use and that it made my work easier and more efficient.

Like

AlienVault provides good information on what's happening on our network.

Like

One of the things that I truly value from this application is that it allows you to filter which emails with company information go to an external receiver

Dislike

The only dislike is that I did not know about this service sooner!

Dislike

In regards to the installation, we didn't receive the level of service that we purchased. The initial setup of the service was not completed in the promised time period. We set up two different services (ArcServe and AlienVault), and later were required to back out all ArcServe related changes and ship back the hardware. Three months after the installation and we're still not done.

Dislike

Sometimes it's a bit complex to customize

    AT&T Secure es very important because it even quarantines those malicious emails and evaluates them avoiding that they meet their objective. Protecting the information of my work is always important and feeling the security and having the support of this app make me trust it almos completely, because nothing is perfect.
