SentinelOne Prompt Security review
Enterprise AI security spanning employee tools, applications, code assistants, and agents.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SentinelOne Prompt Security is an AI security platform for organizations using employee AI tools, code assistants, custom applications, and autonomous agents. It brings discovery, policy controls, and application protections together for mid-market and enterprise organizations that need to govern AI use across those areas. The platform is built into SentinelOne’s Singularity Platform, with integrations listed for GitHub Copilot and Claude Code as well as Singularity.
Its scope spans both user activity and AI application risk. Prompt Security can discover AI tools, including unsanctioned shadow AI, redact sensitive information, and enforce AI-use policies in real time. For custom applications, the vendor describes testing for prompt injection, jailbreaks, and data poisoning before deployment, alongside runtime controls: an AI firewall can block adversarial prompts and scrub sensitive outputs. Code-assistant protections specifically include GitHub Copilot and Claude Code. This breadth suits organizations seeking controls across employee AI and applications, rather than teams looking only for a narrow code-assistant safeguard.
Agent governance is another important part of the offer: the product discovers agents and MCP servers, governs their access and actions, and provides searchable audit logs of agent actions and decisions. That can help organizations track agent activity alongside broader AI use. According to the vendor’s pricing page information, Prompt Security itself is offered through a demo or contact-sales path; public Singularity platform packages do not identify a Prompt Security price. Buyers should therefore expect a sales conversation to establish pricing. The published support channel is documentation. Prompt Security is a stronger fit for organizations seeking centralized employee AI and agent governance than for teams wanting a clearly priced, narrowly scoped tool.
