If you want a maintenance free - Five-9s solution, where the Identity Service Provider has a strong relationship with an array of the Current Cloud Service Providers, and you need to empower your end users from ANY device anywhere in the world, and you still have legacy applications that you want to leverage, then I highly recommend that you stay with The Strong Players:
If you are a small to medium sized shop, geographically localized, have a handful of cloud services on your roadmap, have a relatively homogenous platform requirements (ie: you are a Windows only shop), then the Up and Comers category may suit the bill:
Finally, if you have a strong development team, you run all of your own infrastructure, you have not made a commitment to Cloud Server Providers, but do have a few services that you need access to, then you might want to look at the Build Your Own Federation Toolsets.
Microsoft has gone to great lengths to make ADFS look like a Single Sign On strategy, but again, unless you want to build everything yourself, and base it on an existing Active Directory, this is simply a toolset. For any useful integration with Non-Microsoft infrastructure such as simple LDAP (any ldap provider but Microsoft), you need to provide 3rd party connectors.
As far as a holistic view of Cloud based Authentication and Security, only Okta and Symantec O3 seem to have thought through the endpoint connectivity issues. Both provide the ability to proxy authenticated traffic to your corporate backend without the requirement for traditional VPN clients. Regardless of the endpoint device (corporate or personal, laptop or tablet...) they still conduct granular NAC validation to provide an application view, specific to your credentials and the device/location you are coming from.
The Strong Players: (in their own words)
Okta is an enterprise grade identity management service, built from the ground up in the cloud and delivered with an unwavering focus on customer success.
With Okta IT can manage access across any application, person or device. Whether the people are employees, partners or customers or the applications are in the cloud, on premises or on a mobile device, Okta helps IT become more secure, make people more productive, and maintain compliance.
The Okta service provides directory services, single sign-on, strong authentication, provisioning, workflow, and built in reporting. It runs in the cloud on a secure, reliable, extensively audited platform and integrates deeply with on premises applications, directories, and identity management systems.
Taking a business-driven, rather than an IT-driven approach to identity and access management (IAM) fundamentally changes how organizations approach their IAM challenges, and dramatically improves the value they can obtain.
Specifically, with business-driven identity and access management solutions, companies can empower the business owners to take ownership of identity and access control, provide consistent, full business context across Identity and Access Management systems, connect to the full set of key applications and data resources, and significantly lower the total cost of ownership while scaling to modern enterprise environments.
Symantec O3 is a unique cloud security platform that provides single sign-on and enforces access control policies across web applications. Symantec O3 helps enterprises migrate to Software as a Service (SaaS) applications while ensuring that proper risk management and compliance measures are in place to protect enterprise data and follow regulations.Ping Identity
Symantec O3 improves security without getting in the way of usability. With Symantec O3, end users only have to login once, across all of their web applications. It works equally well for both cloud-based and internal web application use cases.
In short, O3 enables enterprise IT to embrace the cloud while retaining visibility and control – simplifying the use of cloud applications for both enterprise IT staff and for users.

The Up and Comers: (in their own words)
Centrify SSO for SaaS
Centrify's industry-standard solution delivers a single, unified architecture for sign-on.
- For SaaS apps, Centrify addresses these challenges with true single sign-on directly to Active Directory. A cloud service facilitates secure single sign-on and controls access through a security token service, which authenticates users to the portal with Kerberos, SAML, or an Active Directory username/password; then automates logins through a one-click interface when users select from their list of authorized SaaS applications.
- For on-premise apps, native authentication modules plug seamlessly into the underlying Centrify Agent on the managed application host systems, eliminating the need for separate authentication servers, providing single sign-on for SAP NetWeaver, Java and web applications and databases such as DB2.
SailPoint AccessIQ delivers the convenient access to cloud, web and mobile applications that business users want, along with the controls that IT needs to minimize risk. It empowers users with an intuitive App Launchpad for one-click, single sign-on (SSO) to cloud and web applications from any device – at work, home or on the go with mobile devices. And it provides IT with the visibility and controls required to apply security policy, detect violations and ensure regulatory compliance. Application visibility also helps business units control monthly subscription expenses by promptly deprovisioning unused or unauthorized cloud application accounts.EmpowerID
EmpowerID SSO Manager is a Cloud Single Sign-On and Identity Federation platform that supports all of the standard identity protocols - SAML, OpenID, WS-Trust, WS-Federation, and OAuth.Corporate to Cloud Single Sign-on
SSO Manager enables employees, consumers, customers, and partners to access cloud and corporate applications using a single username and password. Federated SSO allows users who are authenticated against one directory to access additional applications and services without re-authenticating when a trust relationship has been established.
Intel Cloud SSO
Intel Cloud SSO is an identity as a service (IDaaS) outsourced solution that removes the complexity and burden of maintaining your own identity infrastructure for user to cloud access.
By leveraging a solution backed by three trusted providers-Intel, McAfee, and Salesforce, you gain assurance that your user's cloud identity is enterprise class secure. Gone are the days of insecure password based log-ins, expense help desk password resets, and IT managed cloud provider integrations for SSO.Intel Cloud SSO is designed for fast, simple deployment by Salesforce or IT administrators that are not security or identity experts. By partnering with Salesforce to deploy on Force.com, we take advantage of native platform capabilities that make configuration a breeze and deliver ready connectivity to hundreds of popular cloud applications.

Enterprise Single Sign-on is the industry’s leading enterprise single sign-on (SSO) solution, basing application and system user logins on existing Active Directory identities. It requires no hard-to-manage infrastructure and streamlines both end-user management and enterprise-wide administration of single sign-on.
Set Up Unified Single Sign-On (SSO) for Web, Cloud and VPN Resources with SecureAuth Identity Provider™ (IdP)
Now you can minimize the number of passwords your users have to remember by providing a single logon to all on-premise web and cloud-based applications without APIs or application modifications. SecureAuth IdP abstracts user data from your native directory so multiple applications can be securely accessed simultaneously using the same credentials.
When two-factor authentication is required, you can easily add this feature to the SSO experience and the same credentials will be used to support web, cloud and VPN resources. With SSO from SecureAuth IdP, your users don’t have to juggle multiple credential sets and administrators aren’t flooded with calls to reset forgotten passwords.
