Sometimes using an outside service provider seems more risky than in-house systems.  In fact, as an auditor for both systems and business processes, I make a case that using GroupMind Express decreases risk for project leaders of sensitive, mission-critical programs and projects.  Perhaps others have more ideas and points to add?

Decreasing Operational Risk

Flexible:
The Leadership Center is instantly scalable, can be started or stopped at will with no penalty, and requires no software downloads nor any purchase.
Current:
Web-focused, it is updated to take advantage of emerging web utilities, tools, and features, while staying compatible with common operating systems and browsers.  Annual upgrades are made available but not imposed.
Reliable and Secure:
The service provider operations center is designed to support 24x7 use to ITIL standards, and technical support is bundled into the service fee.  Disaster recovery is protected with multiple sites and mirrored servers.  All access is logged in by user and IP address, with  explicit permission.

Managing Project Risk

Continuity:  Easily accommodates organization and staff changes.
Transparency:  Open to partners, stakeholders, and executives to build trust and confidence.
Accountability:  Content owners fully responsible for their own information and all use and access.
Collaboration:  Online, with tools to build consensus and make effective decisions.
Documentation:  Self-documenting and compliant with audit and regulatory requirements.  In addition, Project Leadership Center architecture from Conexo is customized from templates that meet Project Management Institute (PMI) standards.
