Tier 2 SOC Automation Tools in 2026

Legion Security helps enterprise security teams scale detection, investigation and response using agentic AI. The platform learns from the real workflows security teams already run, across the SOC and beyond, and turns that institutional knowledge into agentic playbooks the team can trust and audit. This lets organisations adopt frontier AI models gradually while preserving operational trust, cutting manual effort and building toward autonomous security capabilities. Rather than depending on API integrations, Legion combines vision models with other methods to observe how practitioners actually work, so teams can codify those processes as they are or optimise them into transparent, inspectable agentic workflows, extending the same approach beyond the SOC to security operations across the enterprise. Legion Security has offices in New York and Tel Aviv and is backed by Coatue, Accel and Picture, with investors from Island, CrowdStrike, Wiz and Google DeepMind. The company was founded in 2024 by former Microsoft Sentinel team members and emerged from stealth in July 2025.

AtlasCyber is the threat detection and investigation platform of CrunchAtlas Inc., a Portsmouth, New Hampshire company. It applies locally deployed AI agents to an organisation's own network, endpoint and security telemetry to detect, triage and investigate activity, producing evidence-backed cases with a verdict and remediation recommendations rather than raw alerts. An assistant component, ClemAI, supports investigation, threat hunting, forensics, attribution and reporting, and a companion validation capability called PurpleHaze tests whether a flagged exposure is actually reachable and whether a fix closed it. The vendor targets water and wastewater utilities, power and energy, municipal government, manufacturing, education and MSSPs, and states cloud, on-premises and air-gapped deployment with passive ingestion of PCAP, PCAPNG and CSV. CrunchAtlas appears on distributor Carahsoft's site as a public-sector technology partner.

Exaforce is a San Jose company founded in 2023 offering an agentic SOC platform built on a real-time knowledge graph. Four agents the vendor calls Exabots cover detection, triage, investigation and response across more than 100 integrations spanning AWS, Azure, GCP, Okta, GitHub, CrowdStrike and Splunk. Exabot Investigate supports cross-environment pivoting and natural-language hunting, and Exabot Respond executes containment such as isolating instances, disabling users and revoking sessions, with human approval gates where configured. It is sold either customer-operated or as an Exaforce-run managed detection and response service. The company raised $75m in April 2025 and $125m in May 2026.
