What is your experience regarding pricing and costs for Symantec Siteminder?

Siteminder is a little costly. You pay for licensing, and they offer packages, so if you have less users, then you have to buy different products at different prices. If you have more of a user base, then the package is different. They also include other features—for example, if you have a database and you're using Siteminder, then it's good to use a Semantic-specific database, but if you are using less, then you have to purchase the database separately. Whereas if you are going for a bigger license, then it comes within the package. It depends on which plan you are using.

Clients need to pay for a partial license and a subscription license. The pricing is a bit high and they could make it more competitive.

The licensing is fair for this solution.

Symantec Siteminder is expensive; they could definitely do better on the price.

I recommend conducting a PoC on every available product before choose one.

CA solutions.. Are generally expensive but for the customer the ROI is big.
