eSentire, a leader in Controlled Autonomy SecOps, today announced the company has acquired a stealth-mode AI security startup, fully incorporating its product and technology into the eSentire Atlas Platform as Atlas AIDR. Announced in Waterloo, Ontario, acquisition expands Atlas with inline AI security and auditing, giving enterprises out-of-the-box complete AI security, visibility, threat screening, and response actions.
AI is becoming ubiquitous in enterprise organizations. Seventy-six percent of employees now use AI at work, up from 30% two years ago, according to McKinsey. Today, most organizations lack visibility into the basic questions around AI in their environment: who is using AI, what data AI is accessing, where is the data going, and what the cost is, leaving critical gaps with zero audit-ready documentation. The new Atlas AIDR platform module closes that gap. For browser-based AI use, such as an employee using a web-based AI assistant, Atlas can provide visibility through existing telemetry.
Within Atlas Detect, the AIDR module delivers complete AI visibility tracking users, teams, and workstations tied to their AI sessions, alongside a live inventory of agents, models, providers, MCP servers, and tools. Real-time security and inline control redact Personally Identifiable Information before it reaches the model, screen for prompt injections, and enforce custom business logic rules inline to prevent policy violations instantly.
Agent supply chain governance maintains total oversight of external MCP servers and tools autonomous agents actively call, including who uses them and when a server's description or behavior changes. Granular financial and operational tracking monitors full session timelines and token economics per request, rolled up by user, team, and model, complete with custom budgets, automated alerts, and daily anomaly digests.
"Every enterprise is racing to put AI to work, and almost none of them can tell you what their AI agents are doing with their proprietary data, or what they cost," said James C. Foster, chief executive officer, eSentire. "That is a critical accountability and security gap and is exactly the kind of problem eSentire solves for our customers every day. We acquired the security startup team and product and shipped their technology inside Atlas in weeks. That is the difference between a platform and a portfolio: when we buy something, our customers get it. And we do it without forcing anyone to rip and replace — Atlas AIDR can also work with the AI providers and security tools our customers have already chosen. This positions eSentire to lead in securing the AI-driven vendor-independent enterprise rather than react to it."
"You can delegate work to AI. You can't delegate accountability," said Nim Nadarajah, CISO and managing partner, CriticalMatrix, an eSentire partner. "Our clients need more than an AI policy — they need a clear record of what their agents are accessing and the ability to enforce boundaries. Atlas AIDR puts that control into practice, because governance has to work in the business, not just look good in a board report."
This acquisition builds on a period of rapid platform expansion for eSentire. In June 2026, eSentire launched Atlas Preempt, bringing continuous, AI-led autonomous penetration testing and attack path validation to customers, followed in July by Atlas Response, email security, and patch management, unifying detection, response, and remediation in a single platform. eSentire was named a Leader in the 2026 IDC MarketScape for Worldwide MDR Services for the midmarket and brings 25 years of SOC expertise to more than 2,000 organizations across more than 80 countries, protecting over two million endpoints.
