Oracle has officially announced that it will cease the sale of standalone Secure Enterprise Search:

As of early 2014, Oracle has decided to cease standalone sales of Secure Enterprise Search (SES) full use- and connector licenses. SES will continue as an Oracle-internal technology to power search over internal content in WebCenter, Oracle Siebel, PeopleSoft, and Fusion Applications and will be available via restricted use license with these products. Customers who have a full use license will continue to be supported for the lifetime of their SES release.

As part of SES becoming a technology to index Oracle application content only, we anticipate that the remaining content connectors will be phased out of support by mid 2014. This includes Microsoft Sharepoint (all versions), EMC Documentum & eRoom, Oracle EBusiness Suite, and Microsoft NTFS file shares.
