What Inside Agent does
Inside Agent was a London-based identity security startup founded in 2024 that developed a SaaS platform for Microsoft 365 tenant monitoring and Entra ID hardening. The company's core technology automated security posture assessments across Microsoft 365 environments, including Entra, Exchange, Intune, SharePoint, and Teams, identifying and remediating misconfigurations that attackers commonly exploit. Its proprietary capabilities addressed the gap where identity-based attacks account for 40% of all security incidents and 68% of organizations cannot detect these threats until persistence is established. The platform continuously monitored and enforced best-practice security policies to close identity-related gaps before they became incidents.
The company operated with 1-10 employees from a single London office and served organizations seeking to harden their Microsoft 365 and Entra ID environments. No pricing details, customer logos, or revenue figures were publicly disclosed. In November 2025, Inside Agent was acquired by Huntress, a US-based cybersecurity company headquartered in Columbia, Maryland. Following the acquisition, Inside Agent's technology was integrated into the Huntress Platform, forming the basis for Huntress Managed ISPM (Identity Security Posture Management), which pairs with Huntress Managed ITDR (Identity Threat Detection and Response) to provide continuous Microsoft 365 and identity hardening managed and enforced by Huntress experts. General availability of Managed ISPM is targeted for summer 2026.

Inside Agent competitors and assessment
Company assessmentBroad incumbents
- Huntress: Huntress is the strategic acquirer of Inside Agent and the broader platform into which the ISPM technology has been integrated, serving the same SMB and MSP segments with adjacent managed EDR, ITDR, and SIEM offerings.
- Microsoft Defender for Identity: Microsoft's own identity threat detection and posture management capabilities within the Entra and Defender ecosystem represent the most significant broad incumbent, with native deep integration into the Microsoft 365 platform that Inside Agent specialized in.
- Okta: Okta is a broad identity and access management incumbent whose identity threat protection and posture features overlap with the problem space Inside Agent's technology addresses, though Okta competes primarily as an IdP rather than an ISPM specialist.
- CyberArk: CyberArk's identity security platform includes privileged access and identity threat detection capabilities that overlap with the ITDR and identity hardening use cases that Inside Agent and Huntress Managed ISPM target.
- CrowdStrike Falcon Identity Protection: CrowdStrike offers identity protection as part of its broader Falcon platform, providing overlapping ISPM and ITDR capabilities to the same Microsoft 365 and cloud identity customers that Inside Agent and its Huntress product target.
Direct peers
- Semperis: Semperis specializes in identity system security and posture management for Active Directory and Entra ID, making it a direct peer in the Microsoft identity hardening niche that Inside Agent occupied.
- Adaptive Shield (CrowdStrike): Adaptive Shield built a SaaS security posture management platform, which is closely comparable to Inside Agent's posture assessment and continuous monitoring capabilities for cloud identity and SaaS configurations.
- Push Security: Push Security is a direct peer offering an identity security posture management platform focused on SaaS and cloud identity hardening, addressing the same ITDR/ISPM problem space that Inside Agent targeted inside the Microsoft 365 stack.
- Obsidian Security: Obsidian Security provides SaaS security posture management and identity threat detection, directly competing in the ISPM and identity-centric security market that Inside Agent's technology serves.
Emerging players
- Nudge Security: Nudge Security is an emerging SaaS and identity security startup with partial overlap to Inside Agent's Microsoft 365 hardening focus, bringing SaaS discovery and identity governance capabilities to a similar buyer persona.
