What other licensing options are there for GMS products?


After over a decade selling strongly and successfully into a varied global customer base, Gordano has become aware of number of pivotal factors involved in traditional licensing models for the email messaging space.

Unlimited is not unlimited: Gordano has long rejected the notion of the unlimited license. Long experience and customer feedback has made it more than clear that customers want definitive, clear license parameters that describe the server capabilities.

Modularity: Whilst offering flexible deployment options for an almost unlimited variety of scenarios, the GMS modular licensing model also potentially represents a challenge to small to medium sized businesses that are looking for a high value proposition from a high value product.

Scalability: The traditional GMS licensing model offers over 10 incremental breakpoints. More recently Gordano has noted an increased demand for greater flexibility; in a more cautious economic environment it will not always be desirable to add an additional 50 users where only 20 are required. CALs offer an alternative licensing model for SMB customers that require the qualities of a complete messaging suite without the enterprise costs normally associated with the features of such a system.

Enhanced enterprise support: Gordano sells strongly into the Exchange alternative space. Prospective clients in this market will often be considering migrations from legacy MS Exchange environments, or will have a familiarity with the Exchange licensing model. CALs offer a familiar and easy to understand license structure for this type of client.

What is a CAL?
A CAL is an alternative licensing model that provides single keyed access to multiple product capabilities. Instead of using a modular, multi-license deployment, CALs use a single license to activate all of the components of the CAL. CALs also offer useful incremental license scalability options for user population sizes that fall outside of the scope of traditional Gordano license types.

CAL options
CALs are available in two flavors: Standard and Premium.

Standard: A GMS Standard CAL comprises functionality for:

  • Mail (SMTP/POP/IMAP)
  • WebMail/Web Organizer (AJAX HTTP client with full sharing capabilities)
  • Collaboration (Outlook groupware with HTTP client interoperability)
  • Instant Messaging (Dual client IM functionality)
  • Core Anti-Spam (Multiple server-side anti-spam checks)

Premium: A GMS Premium CAL is as a standard CAL as above plus:

  • GMS ASUS (RPD [zero hour] early anti-spam protection)
  • GMS Anti-virus (Dual engine, bi-directional Anti-virus protection)

How are CALs Licensed?
The enhanced anti-malware products within the Premium CAL model are licensed annually.

A fractional Maintenance renewal cost is available for the other GMS products in both CAL models. CAL types may not be mixed on a GMS installation. Each server must comprise either ALL Standard CALs, or ALL Premium CALs.

CALs can only be used to provide the above product combinations, i.e.: either Standard or Premium variants.

A number of traditional modular GMS licensing components may be added as “bolt-ons” to a CAL licensed installation, for example: GMS Archive & Recovery.

GMS users currently utilizing the traditional licensing model may consider CALs as an alternative; the cost and license requirements will depend on a case by case basis. A credit may be made available dependent on the scope of the existing license usage.

CAL Pack Licenses
CALs can be purchased in CAL Packs determined by the user population size to be supported. Increments of 5 CALs are available up to 250 users, Increments of 25 up to 1000 users, increments of 50 up to 2000 users and increments of 100 up to 10,000 users.

For example, a customer with 500 users on their system will purchase a minimum of a 25 CAL Pack to increase their user count.
