From a CIAM perspective, this requires a way of associating a user with the tenant to which they are subscribed.<\/p>\n\n\n\n<p>Tenancy, however, doesn&#8217;t necessarily mean that the users in each community are discrete (i.e. members of only a single tenant). You may have a situation where there is a need to support users who can be associated with more than one tenant \u2014 i.e. where a user is a customer subscribed to more than one tenant of a B2B SaaS application. In such cases, it&#8217;s often important to introduce the notion of a <em>subscribed<\/em> user, where certain user characteristics, such as preferences, say, are treated independently by creating aspects of a user&#8217;s profile that are common across all subscriptions, as well as aspects that are unique to a particular subscription.<\/p>\n\n\n<h3 class=\"wp-block-heading\" id=\"federated-identity\">Federated Identity<\/h3>\n\n\n<p><a data-type=\"page\" data-id=\"1136\" href=\"https:\/\/discovery.cevolution.co.uk\/ciam\/authenticate\/login\/federation\/\" target=\"_blank\" rel=\"noreferrer noopener\">(Enterprise) Federation<\/a> allows an organization to use its existing identity provider (<span class=\"popup-trigger popmake-415\" data-popup-id=\"415\" data-do-default=\"0\">IdP<\/span>) to authenticate users across multiple SaaS platforms without maintaining separate user accounts for each service. <\/p>\n\n\n\n<p>In this case, a B2B organisation integrates its corporate identity provider (e.g., Microsoft Active Directory, Okta, or Google Workspace; typically using protocols like <span class=\"popup-trigger popmake-470\" data-popup-id=\"470\" data-do-default=\"0\">SAML<\/span> or <span class=\"popup-trigger popmake-407\" data-popup-id=\"407\" data-do-default=\"0\">OpenID Connect<\/span>) with a third-party SaaS application, and when users attempt to log in, the SaaS platform redirects them to the enterprise IdP for authentication.

SaaS implementations can then retrieve a user&#8217;s Role(s) from claims provided by the (federated) identity provider, which can help determine which resources or actions the user can access within the SaaS platform \u2014 thus enabling organisations to precisely control who can access specific features or data based on said user&#8217;s role. <\/p>\n\n\n\n<p>Using RBAC can also help simplify tracking and reporting for compliance with regulations (e.g., GDPR, HIPAA, etc). However, whilst RBAC plays a useful role, it does have challenges that leveraging the likes of ABAC (Attribute-Based Access Control) and ReBAC (Relationship-Based Access Control), in addition, can solve (see the below article for more details):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Overlapping Permissions<\/strong>: If roles are not carefully defined, users may receive excessive permissions or be incorrectly restricted.<\/li>\n\n\n\n<li><strong>Role Management Complexity<\/strong>: Managing a large number of roles, especially in larger organisations, can become complex and cumbersome.<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-group is-content-justification-center is-nowrap is-layout-flex wp-container-core-group-is-layout-23441af8 wp-block-group-is-layout-flex\">\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-discover-ciam wp-block-embed-discover-ciam\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"aCV3tJzxga\"><a href=\"https:\/\/discovery.cevolution.co.uk\/ciam\/2025\/03\/18\/authorized-access-control\/\">Access In A Controlled Manner<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Access In A Controlled Manner&#8221; &#8212; Discover CIAM\" src=\"https:\/\/discovery.cevolution.co.uk\/ciam\/2025\/03\/18\/authorized-access-control\/embed\/#?secret=2gBAyoVGGc#?secret=aCV3tJzxga\" data-secret=\"aCV3tJzxga\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n<\/div>\n\n\n<h4 class=\"wp-block-heading\" id=\"contextual-and-adaptive-authentication\">Contextual and Adaptive Authentication<\/h4>\n\n\n<p>Contextual or adaptive authentication dynamically adjusts the authentication requirements based on factors such as the user\u2019s location, device, or time of access. Whilst this can also be beneficial in B2C situations, in a B2B SaaS environment, analysing contextual factors \u2014 such as login attempts from a new device or unusual geographic location \u2014 is particularly useful in determining risk levels upon which assessment for additional verification (e.g., MFA) can be made.<\/p>\n\n\n\n<p><strong>Benefits<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Security and User Experience<\/strong>: Provides stronger authentication when risk is high, but allows users to authenticate easily under low-risk circumstances.<\/li>\n\n\n\n<li><strong>Reduced Friction<\/strong>: Prevents unnecessary authentication challenges for users on trusted devices or in familiar locations.<\/li>\n<\/ul>\n\n\n\n<p><strong>Challenges<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Risk Calculation Complexity<\/strong>: Accurately assessing the risk level of login attempts requires sophisticated algorithms and data analysis.<\/li>\n\n\n\n<li><strong>User Confusion<\/strong>: Legitimate users may be blocked or delayed due to misinterpreted context, leading to frustration.<\/li>\n<\/ul>\n\n\n<h2 class=\"wp-block-heading\" id=\"b2c-to-b2b-evolution-and-beyond\">B2C to B2B Evolution and Beyond<\/h2>\n\n\n<p>An effective CIAM integration can pave the way for B2C applications to more readily evolve to service a B2B SaaS audience as well. For example, with the right CIAM implementation, a B2C travel-oriented application or a B2C application for (project) planning, say, can be packaged to provide service to user communities across multiple organisations.<\/p>\n\n\n\n<p>An effective CIAM integration can also easily support the various permutations often seen in a B2B SaaS context. B2B2C \u2014 a business model where two companies collaborate to deliver SaaS solutions to the same end customer, or B2B2B, a business model where two companies collaborate to deliver SaaS solutions to another business, are just two examples of other possible B2B style opportunities that can be realised.<\/p>\n\n\n\n<p>For more information on choosing the right CIAM approach, see the article entitled:<\/p>\n\n\n\n<div class=\"wp-block-group is-content-justification-center is-nowrap is-layout-flex wp-container-core-group-is-layout-23441af8 wp-block-group-is-layout-flex\">\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-discover-ciam wp-block-embed-discover-ciam\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"cgvwgkTFos\"><a href=\"https:\/\/discovery.cevolution.co.uk\/ciam\/2025\/02\/22\/diy-or-buy\/\">Build, Buy or DIY your CIAM Solution?<\/a><\/blockquote><iframe loading=\"lazy\" class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Build, Buy or DIY your CIAM Solution?&#8221; &#8212; Discover CIAM\" src=\"https:\/\/discovery.cevolution.co.uk\/ciam\/2025\/02\/22\/diy-or-buy\/embed\/#?secret=hSCsT7BTZS#?secret=cgvwgkTFos\" data-secret=\"cgvwgkTFos\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n<\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The CIAM requirements for B2C and B2B SaaS differ significantly due to the varying needs for security, complexity, and user experience.
