Akamai Guardicore Segmentation uses AI to automate policy generation and identify application behavior. The company released these AI-powered capabilities on March 24, 2026, following an analysis of 500 segmentation projects to identify process bottlenecks. The new features enable continuous discovery and continuous risk containment by correlating exposure-aware detection with segmentation enforcement. The system also provides delegated, application-owner workflows through the App Owner Portal to speed up approvals. Because the AI discovers application behavior, generates and explains segmentation policies at scale, simulates impact, and validates readiness before enforcement, organizations reduce manual effort and operational risk. Continuous discovery allows for real-time understanding and provides a foundation for Zero Trust. Akamai Guardicore Segmentation provides the most effective tool for managing large-scale Zero Trust deployments.
Illumio remains a major competitor
Illumio remains a significant competitor in the segmentation market despite its active IPO process. The company filed an S-1 registration statement with the SEC in February. Illumio has raised $1.24B in total venture capital and private equity funding, including a $225M Series F round. While Illumio focuses on preventing the spread of ransomware, Akamai integrates its Guardicore platform into a much broader security portfolio. Founded in 2013, Illumio acts as a niche player that specializes in microsegmentation. CEO Andrew Rubin notes that zero-trust frameworks help organizations protect themselves from destructive cyberattacks. You should monitor how the current Illumio IPO process affects the valuation of all segmentation platforms.

Security growth and agent updates
Akamai’s security revenue grew 10% in the second quarter of 2026, reaching $604 million. This growth follows the acquisition of LayerX, which Akamai rebranded as Akamai Workforce Protector to manage AI usage. The company provides the Guardicore Platform Agent 7.4.0, which supports macOS 26 Tahoe and provides anti-tampering features for Windows and macOS users who require a code to prevent unauthorized individuals from disabling or suspending agent services. Administrators can enter a code in Enterprise Center to prevent unauthorized users from disabling or suspending agent services. The Guardicore Platform Agent 7.4.0 resolves vulnerabilities like CVE-2026-46449 and CVE-2026-50216. Akamai signed a $40 million, four-year segmentation agreement with a large North American financial institution. The company saw demand for WAF from a world-leading commerce site and a major bank, which both upgraded to protect all applications against vulnerabilities exposed by models like GPT 5.5. The device inventory report in Enterprise Center includes GC status, OS version, and device serial number. This report helps administrators maintain visibility over all managed assets. The installer for version 7.4.0 automatically removes the standalone GC Agent on macOS. Will the increased demand for AI inference capacity impact the budget available for microsegmentation software?
