Rezonate is an identity security company that protects human and machine identities across identity providers, cloud infrastructure and SaaS applications. It is built for security and DevOps teams that need one view of who and what can access their cloud estate, and a way to reduce that risk and respond to identity based attacks as they happen.
Rezonate is now part of Silverfort and continues under its own brand.

What Rezonate Does
Identity risk in the cloud is spread across many places: an identity provider holds the users, each cloud account holds its own roles and keys, and SaaS tools hold yet more access. Rezonate pulls these into a single picture so a team can see every identity, human or machine, and what it can reach. From that shared view the platform can find risky access, watch for live threats against identities and inform access decisions, before and during an attack. Since joining Silverfort, Rezonate supplies the cloud side of Silverfort’s identity protection, including non-human identity security in cloud environments.
Products
Identity Storyline
Identity Storyline is the foundation of the platform. It builds one record of each human and machine identity and its activity across identity providers, cloud and SaaS, so analysts can follow what an identity did and where it has access without moving between consoles. The other products read from the same data.
Identity Security Posture Management (ISPM)
ISPM is for teams that want to cut identity risk before it is exploited. It focuses on proactive identity risk mitigation and includes entitlement management, so teams can find and reduce risky access across cloud and SaaS accounts.
Identity Threat Detection And Response (ITDR)
ITDR watches for identity based threats in real time across cloud identity providers, cloud infrastructure and SaaS. It gives a security team the context to understand an incident involving an identity and respond while it is still unfolding.
Adaptive Access
The Adaptive Access Engine uses the same identity context to inform access decisions, so what the platform knows about an identity’s risk can shape whether and how it is granted access.
Zoe
Zoe is an AI assistant built into the platform. It turns plain language questions into queries against Identity Storyline, so an analyst can ask who has access to a resource without writing a query. It can also pull access review and compliance reports on request. Because it works on top of Identity Storyline, it covers the same identity providers, cloud and SaaS sources as the rest of the platform.
How It Works
Rezonate runs as an agentless service that reads from the systems an organisation already uses and builds its identity view from them.
| Component | What it does |
|---|---|
| Connections | The platform connects to identity providers, cloud infrastructure accounts and SaaS applications, giving a unified view across identity and cloud infrastructure providers. |
| Analysis | Continuous identity posture data is combined with identity activity, and anomalous activity is traced as an attack chain from the root exposure to the attacker’s actions. |
| Security stack | Findings feed SOC, XDR, SOAR, IdP and IAM technologies, and Zoe delivers risk alerts into Slack or Microsoft Teams. |
