CASB Is Changing the Scene for IDaaS Products

Lately, it is noticed that a trend is seen amongst corporate companies where more and more firms are tending to opt for the use of identity capabilities that are built into their CASB (Cloud Access Security Brokers) solutions in lieu of some dedicated IDaaS (Identity-as-a-Service) product. As CASBs identity functionalities have evolved considerably, there is a lesser need for some separate and standalone product for this purpose and it is seen that it is the beginning of CASB solutions eating out the market for IDaaS products. IDaaS was in boom earlier regarding the cloud security concerns. Enterprises are confused regarding CASB Vs IDaaS when it comes to cloud security. But, an effective solution lies in deploying an integrated approach of both models.

Benefits of IDaaS:

  • Identity Governance and Administration: The cloud service provider will be able to automate the synchronization of identities to target applications and other storage. But, with IDaaS administrative interface, the client’s admin can manage identities directly thus allowing the users to reset their passwords. Additional responsibilities provided by the vendor’s IDaaS interface will include supporting identity life cycle processes, access requests, role management, and governance over user access to crucial systems.
  • Access: Vendors may provide authentication and Single Sign-On (SSO) to secure the applications of their clients. Additional authentication methods may also be provided through integration with third-party authentication tools.
  • Identity Log Monitoring and Reporting: The vendors provide their clients with log data so that the clients can do their own analysis regarding the grant access and the users who have accessed the target systems.
  • Cost Price: IDaaS helps organizations to cut down security costs. It offers scalability and better security at a nominal price.

CASB (Cloud Access Security Brokers)

Cloud Access Security Brokers provide their cloud security solutions for both on-premises and cloud-based infrastructure. These CASB solutions include features like single sign-on (SSO), Data Loss Prevention (DLP), Shadow IT, Multi-factor authentication (MFA), and automated provisioning for apps and devices.

CASB Benefits for Enterprises

  • Compliance: CASBs help enterprises to achieve compliance protocols with regard to rules and regulation in the security standards like HIPAA, PCI DSS, etc
  • Visibility: CASBs gives organizations comprehensive application visibility after authentication regarding their users, devices being used, and the data that is moving or stored.
  • Data Security: The extra features in CASB solutions ensure that enterprises get an extra security layer without any hindrance to the running of the applications.
  • Threat Protection: CASBs use protection and detection methods to control unauthorized access to devices, systems, and apps.


In comparison with CASB Vs IDaaS, the benefits of both IDaaS and CASB are to be compared, then it can be found that CASB solutions offer most of the IDaaS capabilities as a part of their cloud protection suites. In fact, CASBs can offer better features like the following:

  • Logging and Reporting: In comparison with CASB Vs IDaaS, CASBs log and report on every single transaction like login, logout, and all that happens in between, whereas, IDaaS can report on login and logout events, but nothing during the session.
  • Multi-Factor Authentication: CASB solutions can trigger MFA at any time including the mid-session if it notices any suspicious content or activity, whereas, IDaaS can trigger MFA only at the beginning of the session.

IDaaS and CASB

IDaaS can be clubbed with CASB solutions to provide a complete cloud security layer to the enterprises. It helps in injecting enterprise-grade authentication into cloud-based resources thus bettering cybersecurity. The benefits of a combined solution include the following:

  • It offers comprehensive visibility into the on-premise and public cloud infrastructure through the deployment of efficient governance policies like user identity, granular access restrictions based on certain parameters to specific documents, detection of high-risk users and incidences, and privileged user account monitoring.
  • It helps in detecting suspicious behavior across IDaaS platforms through machine-learning patterns, which may otherwise go undetected.
  • It is capable of modifying and accessing the risks associated with third-party apps, which may otherwise prove to be too risky to the enterprises.
  • It is used to collect user activity data across multiple cloud environments to detect data breaches. It helps enterprises to reduce investigation times and comply with the security standards.

Thus, even though CASBs offer comprehensive data protection capabilities for cloud applications, a combined IDaaS and CASB solution will work wonders for enterprises to achieve security as well as compliance.
