Antepos OPN platform was one of the first IM systems to offer broad interoperability with other IM platforms, and this release improves that interoperability by adding support for Microsofts Office Communicator 2005 IM client. OPN System Rivoli brokers the SIP/SIMPLE session between the two clients, allowing OPN System Rivoli users to leverage Communicators VOIP features as well as its built-in whiteboard and desktop and application sharing features. In fact, the combination of OPN System Rivoli and Communicator 2005 is a viable alternative to Microsofts Office Live Communications Server 2005. OPN System Rivoli is considerably less expensive than Office Live Communications Server, and it can integrate with Active Directory without extending the AD schema.
However, Antepos integrated compliance management and security tool set will appeal to corporations evaluating the platform. The compliance tools gave us a way to set policies that established intra-organization boundaries, appended message disclaimers and provided policy audit workflow. The security tools, which block file attachments based on extension, will be useful especially for smaller organizations looking to implement management policies for IM. Companies with a higher regulatory bar will still need third-party products for auditing and monitoring IM use, however. Next page: Evaluation Shortlist: Related Products.
Using OPN System Rivoli with Communicator does incur some management overhead when compared to Antepos own OPN Client, however. We had to deploy a policy for the Communicator client to change the clients default security settings. We also had to manage keys for brokering TLS (Transport Layer Security)-based encrypted communications.
