Frederic Hautecoeur - PeerSpot reviewer
Senior System Integrations Architect at bs-team
Integrated web hosting has simplified secure services and has supported long-term growth
To be honest, I do not see any major areas for improvement. Perhaps something simple and minor. It should not go more complex than it is at the moment. The only disadvantage I see is that the documentation is a bit difficult to find. There is a lot of configuration that is very hard to get information about.

Quotes from Members

"The product is flexible."
"The products offers EE support."
 

Cons

"The cost is a bit too high."
"IIS's memory management could be improved."
"The only disadvantage I see is that the documentation is a bit difficult to find."
"The first level of support is not very good because by the time we speak with them, we are already past that point."
"The product could be more compatible with Linux and macOS, particularly when applying user configuration policies."
"The visibility feature of the product is an area with certain shortcomings where improvements are required."
"The security must be improved."

Pricing and Cost Advice

"The yearly licensing cost is very high. The solution is very expensive."
"The product's price is not high."
"IIS's pricing is not expensive."
"I was using the trial version of IIS inside my virtual machines."
"There is no license needed to use the solution."
"The solution provides multiple licensing options."
"The price is good."
"There is no license required for the product as it is role-based. Whenever you go for a Windows platform server, the role has to be installed directly from the server manager. There is no additional cost that has to be paid for that. It is free to use."
