AI continued to be a major running theme for cybersecurity mergers and acquisitions (M&A) for the year in June 2026, as several prominent companies made moves to boost their offerings around agentic AI and AI agents.
Operational technology (OT) cybersecurity company Dragos featured strongly in June deals, after it opened up the month with an acquisition, while the middle of the month saw the announcement that Accenture had acquired a majority stake in the company.
The month also featured cybersecurity companies making further investments into identity and supply chain security, while an AI company continued to strengthen its security offerings.
Here is Infosecurity’s cybersecurity M&A roundup for June 2026.
Dragos Acquires xIoT Security Specialist Phosphorus
Dragos confirmed it had acquired Phosphorus, the provider of extended Internet of Things (xIoT) security and management platforms, in a June 1 announcement.
The OT security firm said it had acquired Phosphorus to extend the Dragos Platform to help protect the billions of connected devices embedded across critical infrastructure and operational networks. The deal will provide Dragos customers with expanded asset visibility and integrated device intelligence.
“The connected devices you find everywhere in critical infrastructure are largely invisible to the cybersecurity programs that protect operational environments. With Phosphorus, we close that gap and secure xOT, the full environment that matters.” said Robert M. Lee, CEO and Co-Founder of Dragos.
Accenture Agrees Majority Stake in Dragos
On June 18, it was announced that international technology consultancy Accenture had agreed to acquire a majority stake in Dragos. The move will combine the Dragos platform with operational technology experts at Accenture and their existing relationships with critical infrastructure operators.
The acquisition will also see Dragos run in conjunction with runZero and NetRise, in a move designed to deliver a unified solution that enhances visibility, accelerates threat detection and response and strengthens Dragos’ ability to scale adoption of its broadened platform.
“Our clients across industries and regions are asking us how to be more proactive and integrated in their approach to cybersecurity. The addition of Dragos, complemented by runZero and NetRise, fills this important need,” said Julie Sweet, chair and CEO, Accenture.
The transaction is expected to close in August or September 2026, subject to customary closing conditions.
1Password Boosts AI Identity Security Offering with Apono Acquisition
On June 15, 1Password announced that it had acquired Apono, the identity security provider which focuses on just-in-time access governance.
The acquisition extends 1Password’s identity security platform beyond securing credentials to governing what every human, machine and AI identity can access. Only the permissions the task requires are received and only for the duration of that task, with a complete audit record of every action taken.
"Agentic workflows have exposed how fragmented enterprise identity really is, built in silos for a world before AI,” said David Faugno, CEO of 1Password
“By combining Apono's just-in-time provisioning and intent-based policy enforcement with 1Password's zero-knowledge vault and Credential Broker, we’re delivering the answer: unlocking the highest-value AI use cases while keeping people in control."

Panther is the third security acquisition announced by Databricks, following the recent acquisitions of Antimatter and SiftD.ai.
“With Panther, we enhance and expand our ability to analyse all data and automate SOC workflows. Together, we can offer the best platform to help defend the world against agentic attacks,” said Ali Ghodsi, co‑founder and CEO of Databricks.

“We have always believed that privacy and fraud prevention are not a trade-off, but part of the same problem, solved together or not at all,” said Ricardo Amper, founder and CEO of Incode. “Identiq is the piece that enhances our Privacy by Design architecture, the natural culmination of the decisions we made on day one.”
Aikido Acquires Root to Defend Open Source Supply Chains Against AI Attacks
On June 30, Belgian cybersecurity company Aikido announced it had acquired Root, a cyber start-up which deploys AI agents to find and patch security vulnerabilities in open source platforms at machine speed.
With the acquisition of Root, Aikido aims to help developers and AI agents securely build applications with open source software in the face of supply chain attacks.
“Open source needs patching, and it needs it fast,” said Willem Delbare, co-founder and CEO of Aikido Security.
“With Root, we fix what teams are actually running, generating hundreds of verified patches a day: no upgrades, no migrations, no breaking changes. That's how supply chain security gets solved for everyone, not just the 1%.”
