Attivo Networks

Attivo Networks was a cybersecurity company focused on deception-based threat detection and, later, identity security and lateral movement protection. Its ThreatDefend Detection Platform was positioned as an active defense layer providing early detection, forensics, and automated incident response for attacks already inside a network, covering user networks, data centers, cloud environments, and specialized attack surfaces. The portfolio spanned network, endpoint, application, and data deceptions intended to misdirect attackers and reveal activity across threat vectors, with machine learning used to simplify preparation, deployment, and operation. Attack analysis and forensics produced actionable alerts, and native integrations automated blocking, quarantine, and threat hunting.

Over time the company extended into identity security, marketed as Identity Threat Detection and Response (ITDR). Its identity suite addressed credential theft, privilege escalation, lateral movement, data cloaking, and identity exposure, supported conditional access and zero trust models, and included an Active Directory assessment tool that surfaced misconfigurations, suspicious password and account changes, credential exposures, and unauthorized access. A network and cloud-based deception suite used breadcrumbs and decoy accounts, files, and IPs to lure attackers into revealing themselves.

Following the May 2022 acquisition, Attivo's technology was folded into SentinelOne's Singularity XDR platform as Singularity Identity (real-time Active Directory and Azure AD infrastructure defense plus deception-based endpoint protection), Singularity Ranger Active Directory Assessor (cloud-delivered continuous identity assessment), and Singularity Hologram (network-based threat deception). The attivonetworks.com domain now presents SentinelOne's platform, which markets AI-native endpoint and identity protection in a single lightweight agent covering supply chain, ransomware, behavioral, and credential-misuse attacks, deployable in SaaS, on-premises, hybrid, and air-gapped environments.
