Who it fits
Not written yetFrom its own pages, Orchid Security sells mainly to teams in regulated industries under audit pressure and to identity programs with persistent blind spots. Orchid says it covers self-hosted and SaaS applications, along with cloud, on-prem, legacy, and custom-built applications. Orchid describes the risk of orphaned accounts left behind during an acquisition, so organisations that grow through acquisitions are among the buyers it addresses. Orchid integrates with existing IAM, PAM, and IGA tools rather than replacing them, so it speaks to organisations that already run those systems.

About Abnormal AI

Abnormal AI sells a behavioral security platform that protects email, identity, and AI. Abnormal says AI-generated attacks are often too subtle for humans to see and too new for traditional threat intel to detect. Abnormal AI says its platform stops the attacks that slip past legacy gateways, including business email compromise, advanced phishing, vendor fraud, and account takeover. Abnormal AI states its mission is to stop crime with AI.[15]

Abnormal AI says its platform connects AI tools, people, agents, and cloud activity through behavioral context to govern adoption, enforce policies, detect threats, and support investigations. The platform has native API integrations across Microsoft 365, Google Workspace, Okta, CrowdStrike, and the customer's SIEM and SOAR. Abnormal AI says each supported connection helps Abnormal understand activity, investigate threats, and apply the controls the customer's team authorizes. Abnormal AI describes Attune as the behavioral AI model that learns what is normal and detects what does not fit. AI Data Analyst lets users ask plain-English questions and get security insights instantly.
