Rig Security vs Silverfort when AI agents act under employees’ names

Rig says its correlation engine matches accounts to the right person with more than 96.8% accuracy, resolving an Okta login, an AWS IAM user, a GitHub handle, a Snowflake role, a service account, and an AI agent to one engineer. That is a vendor figure. The problem behind it is that when an agent runs inside a developer’s session, most identity tools only see the developer.

Silverfort sells runtime identity security that sits inline on authentication across Active Directory, cloud, legacy systems, and OT without system changes. Its platform covers Universal MFA, an authentication firewall, ISPM, ITDR, NHI security, and privileged access, and it has added an Identity Graph and AI Agent Security with human owner mapping. Rig came out of stealth in September 2026 with RICE, which ties every identity to a human owner, plus least-privilege and detection modules and Gatewatch, an endpoint control that blocks an agent’s command without blocking the employee. Rig’s capabilities are new launch claims, stated rather than demonstrated.

Buy Rig Security when AI agents and service accounts acting on developer laptops and across cloud, SaaS, and code are the risk and each must trace to an accountable person. Buy Silverfort when the requirement is inline MFA and access policy on every authentication, including AD, legacy protocols, OT, and service accounts.

Overview

	Rig Security	Silverfort
Primary use case	Identity protection that resolves people, NHIs, and AI agents to one human owner and enforces policy on agent actions	Runtime identity security across AD, cloud, legacy, and OT: MFA, authentication policy, posture, detection, and NHI protection
Day-to-day workflow	Review each person’s resolved map of accounts and agents, remove unused grants, investigate correlated alerts, and allow or block agent commands on endpoints	Set MFA and authentication firewall policies, review identity posture findings, and respond to identity threats inline
Main buying consideration	No public pricing. Sold by demo	Core, Plus, Advanced, and Enterprise packages on Silverfort’s pricing page, all quote-based with no published USD rates

We reviewed Rig Security’s homepage and its September 2026 launch release, plus Silverfort’s homepage, pricing and packages page, and customer stories page, on 14 Oct 2026. We did not run either product.

Rig Security

Silverfort

Editions and pricing

Both sell by quote. Silverfort names four packages. Rig sells one platform with see, protect, and enforce modules.

	Rig Security	Silverfort
How it is sold	One platform: NHI security, posture and attack paths, least privilege, threat detection and response, and shadow AI enforcement through Gatewatch	Core (ISPM, Universal MFA), Plus (adds NHI Security and AI Agent Security), Advanced (adds Authentication Firewall and ITDR), and Enterprise (adds Access Intelligence and Privileged Access Security), plus a la carte options
Deployment	Gatewatch runs on developer laptops, servers, and clusters. Other connector types are not confirmed in public documentation	Inline integration with existing identity infrastructure, with no infrastructure changes and first protection in under 24 hours per Silverfort
AI agent scope	Agents running in human sessions on endpoints, such as coding agents and MCP servers	AI Agent Security in Plus and above: discover and monitor AI agents, control their activity with real-time access policies, and map human owners. The product menu highlights runtime control for agents on Google Cloud

Identity correlation and ownership

Both build a graph of identities and both map agents to human owners. Rig makes that resolution the core of its product.

	Rig Security	Silverfort
Graph model	RICE clusters accounts over shared devices, sessions, groups, keys, and credentials, with a scoring model for each candidate match	Identity Graph discovers identities and their relationships, with Access Intelligence for context on access rights
Non-human identities	Service accounts, workloads, and tokens traced back to the person who created, runs, or benefits from them	NHI Security in Plus and above to discover NHIs and service accounts, map how they are used, and enforce virtual fencing
Posture	Attack paths that chain harmless-looking grants into routes to production	ISPM to find and fix identity weaknesses

Where policy is enforced

Both enforce at runtime. They enforce at different points.

	Rig Security	Silverfort
Enforcement point	Gatewatch at the point of execution on the endpoint, judging each agent command	Inline on authentication requests, including protocols and systems that never had MFA
Agent versus human	Tells an AI agent apart from the person whose session it uses and blocks only the agent’s risky action	Real-time access policies on agent activity in Plus and above. Separating an agent from the human whose endpoint session it uses is not confirmed in public documentation
Legacy and OT	Not confirmed in public documentation	Universal MFA and authentication firewall for legacy, on-prem, and OT environments

Choose Rig Security when coding agents and service accounts running under developers’ identities are the gap, and you need each one tied to an owner and stopped command by command on the endpoint. Choose Silverfort when MFA and authentication policy must reach Active Directory, legacy protocols, OT, and service accounts inline, with ITDR on the same platform.
