This consolidation is intended to create a unified platform for industrial and critical infrastructure cybersecurity, offering improved visibility and threat response mechanisms. Belgium-based Aikido Security acquired Root, an Israeli-founded startup focused on automated vulnerability remediation, in a deal estimated at $70 million to $100 million.
