Overview
Silverfort is a cybersecurity company whose principal business is identity security. Founded in Israel in 2016 by Hed Kovetz, Yaron Kassner, and Matan Fattal, the company developed a platform intended to provide broad visibility into identities and authentication activity across an organization’s digital environment. Its technology is designed to work across cloud services, on-premises infrastructure, applications, devices, Active Directory environments, service accounts, privileged accounts, and other non-human identities. The company positions its platform as an identity security and identity visibility capability rather than as a replacement for a single directory, authentication, or endpoint product. Its stated use cases include identity threat detection and response, identity-based protection, multi-factor authentication, service-account and non-human-identity protection, privileged access security, and ransomware defense focused on limiting lateral movement. Gartner has described Silverfort in the context of identity visibility and intelligence platforms. Silverfort was established in Israel and is headquartered in Dallas, Texas. It operates internationally, with offices in more than 18 locations across North America, Europe, and Asia-Pacific. The company has formed technology and go-to-market relationships with major security and identity vendors, including Microsoft, Okta, Duo, Ping Identity, Palo Alto Networks, SentinelOne, and Check Point. Its Microsoft relationship is centered on helping organizations consolidate identity security across devices, applications, and environments associated with Microsoft Entra ID, formerly Azure Active Directory. The company has financed its expansion through venture investment. Publicly described rounds include a 2018 Series A led by TLV Partners, a 2020 Series B led by Aspect Ventures, a 2022 Series C led by Greenfield Partners, and a 2024 Series D led by Brighton Park Capital. The January 2024 round was reported as the company’s largest financing at that point and brought total disclosed funding to approximately $222 million. Silverfort has continued to broaden its product scope beyond conventional human-user authentication. It has expanded protection for service accounts and cloud-based non-human identities, introduced identity-first incident response capabilities, and launched privileged access security features based on just-in-time controls. In 2025, it also introduced an AI Agent Security product as concern increased about the identities and permissions used by autonomous software agents. The company has additionally publicized research into weaknesses involving single sign-on, NTLM authentication, Active Directory, and related identity infrastructure. In March 2025, Fast Company recognized Silverfort in its security-focused Most Innovative Companies coverage. In June 2025, Howard Greenfield joined as President and Chief Revenue Officer, and in July 2025 Silverfort announced a technical integration with CrowdStrike intended to improve analysis by correlating identity and endpoint information.
History
Silverfort was co-founded in Israel in 2016 by Hed Kovetz, Yaron Kassner, and Matan Fattal. The company emerged in the cybersecurity sector with a focus on identity security across environments that traditional authentication and access-management tools may treat separately. Its platform was designed to analyze and protect identities and authentication activity spanning on-premises infrastructure, cloud services, applications, devices, and directory systems. The company’s early growth was financed through venture capital. On June 25, 2018, Silverfort completed a Series A financing of $11.5 million led by TLV Partners. On August 4, 2020, it completed a $30 million Series B round led by Aspect Ventures. These financings supported the development and commercialization of a platform intended to extend identity protection beyond standard directory boundaries and conventional multi-factor authentication deployments. In March 2021, Silverfort entered a partnership with Microsoft. The relationship focused on helping customers consolidate identity security across devices, applications, and environments connected with Microsoft Entra ID, known before its rebranding as Azure Active Directory. Silverfort also developed relationships with other security and identity companies, including Okta, Duo, Ping Identity, Palo Alto Networks, SentinelOne, and Check Point. These relationships reflected the company’s strategy of integrating with existing enterprise security and identity ecosystems rather than requiring customers to operate an isolated identity stack. Silverfort raised $65 million in a Series C financing announced on April 12, 2022, led by Greenfield Partners. Its product and research scope subsequently expanded toward identities that are not directly associated with employees. In December 2023, the company announced improvements to service-account protection intended to support larger-scale deployments. Service accounts are important to enterprise operations but can be difficult to govern because they often support applications, scheduled processes, infrastructure, and automated workflows. The company announced further product expansion in 2024. In September, it introduced an identity-first incident-response capability designed to block suspicious authentication attempts during active security incidents. In December, it released Privileged Access Security, with just-in-time access controls intended to reduce persistent privileged permissions. On January 23, 2024, Silverfort also closed a $116 million Series D round led by Brighton Park Capital. Public descriptions of the financing placed the company’s total raised capital at approximately $222 million. Silverfort’s research activity has addressed identity weaknesses involving single sign-on, NTLM authentication, and Active Directory. At RSA Conference 2024, researcher Dor Segal presented work concerning a way to bypass modern authentication protocols. In January 2025, he published details about an Active Directory Group Policy misconfiguration that could permit NTLM authentication. In July 2025, he described an Active Directory vulnerability known as NOTLogon, assigned a 6.5 CVE rating in the supplied reference material, which could allow a domain-joined machine with minimal privileges to send a specially crafted authentication request capable of crashing and rebooting a domain controller. In March 2025, Fast Company included Silverfort among its Most Innovative Companies in the security category. In June, Howard Greenfield joined the company as President and Chief Revenue Officer, while Silverfort launched AI Agent Security in response to growing concern about the identities and permissions used by AI agents. In July 2025, the company announced a technical integration with CrowdStrike to improve detection accuracy by correlating identity and endpoint data. Silverfort is headquartered in Dallas, Texas, and reports offices in more than 18 locations across North America, Europe, and Asia-Pacific.

Products and positioning
An enterprise identity security platform designed to provide visibility, detection, authentication protection, and response controls across hybrid environments and both human and non-human identities.
Identity security platform
Silverfort Identity Security Platform
Silverfort’s core platform is designed to provide identity visibility and security controls across hybrid enterprise environments. It addresses identities and resources in on-premises and cloud settings and can be deployed alongside existing identity, security, and access products. Core capabilities described for the platform include identity threat detection and response, identity-based protection, multi-factor authentication, and defenses intended to restrict ransomware-driven lateral movement.
Non-human identity security
Service Account Protection
This offering is intended to discover and protect service accounts used by applications, infrastructure, scheduled processes, and automated workflows. Silverfort announced enhancements in December 2023 aimed at making protection more scalable for organizations with large numbers of service accounts and complex hybrid environments.
Non-human identity security
Non-Human Identity Protection
Silverfort’s non-human identity capabilities address identities used by workloads, applications, services, and cloud resources rather than employees. In May 2025, the company announced an expansion intended to cover cloud-based non-human identities, extending its identity-security approach to automated and machine-driven access.
Identity threat detection and response · 2024
Identity-First Incident Response
Announced in September 2024, this capability is designed to make identity controls part of incident response.
