As you can see, both sqreen and IMVision can be used as SaaS solutions, but IMVision can also act as a separate on-prem or hybrid environment to monitor GraphQL and REST API interactions. On the other hand, sqreen supports simple Slack notification, which is much more convenient for your team than emails from IMVision. More to say, sqreen integrates with Splunk SIEM, ensuring detailed analysis of all suspicious API authorization and authentication attempts.
