Question: Can you recommend a solution to manage machine identities across multiple platforms and environments?

For managing machine identities across many platforms and environments, Venafi is a good option. The company's platform is designed to orchestrate machine identities across many environments, including on-premises and cloud. With its TLS Protect, SSH Protect and CodeSign Protect products, Venafi aims to reduce complexity, eliminate outages and automate certificate provisioning to create a machine identity management system that's both secure and observable.

Another powerful option is CyberArk, an identity security and access management platform. CyberArk offers secure Single Sign-On, Adaptive Multi-Factor Authentication and lifecycle management for human and machine identities. It serves a broad range of industries and offers flexible pricing, so it can be a good option for those who want to maintain a strong identity security posture.

For the most sensitive organizations, RSA offers a Unified Identity Platform. It's designed to provide automated identity intelligence, strong authentication, access, governance and lifecycle management. RSA's platform spans cloud-only, hybrid and on-premises environments, so it's good for government, financial services and healthcare customers.

Also worth considering is Axonius, which offers a unified system of record for managing cybersecurity assets and SaaS applications. It combines data from more than 800 sources to spot security gaps, automate remediation actions and enforce policies. It can manage devices, identities, software and SaaS applications, and can help with threat hunting and remediation automation.
