Examples of error remediation in SaaS portals is disclosed. In an example, activity data in a SaaS portal is monitored, where the SaaS portal is from amongst a plurality of SaaS portals grouped in a portal group. The activity data includes a record of events associated with a service request processed by the SaaS portal, an alert notification on occurrence of an error in the SaaS portal, and user information relating to credentials provided by a user accessing the SaaS portal. A runtime error in the SaaS portal may be detected based on the monitored activity data. The runtime error is based on faults in a service or an Application Programming Interface (API) associated with the SaaS portal, a security vulnerability, and non-compliance with a configuration policy governing the SaaS portal. A remediation measure for the runtime error is determined and implemented in the portal group.
