Global Autonomous Software Security Posture Management, Runtime Firewalls and Agent Governance Market — Intelligence Report

The global market for autonomous software security posture management, runtime firewalls and agent governance is moving from an experimental control category into a core enterprise security priority. Nexvora Intelligence estimates the market at US$•••–••• billion in 2025, expanding rapidly as enterprises deploy copilots, embedded agents, retrieval systems, orchestration frameworks and third-party model endpoints across customer service, software engineering, finance, healthcare and regulated operations.

Demand is being pulled by a widening security gap: traditional application security, identity governance, data-loss prevention and cloud posture tools were not designed to continuously inspect prompts, tool calls, agent actions, sensitive context exposure, model-routing decisions or autonomous workflow permissions. This has created a new control plane spanning discovery, inventory, policy enforcement, red-team testing, runtime filtering, data boundary protection, auditability and kill-switch governance.

Runtime firewalls are becoming the highest-urgency subsegment, particularly for enterprises exposing autonomous interfaces to employees, customers or partners. Buyers are prioritizing protection against prompt injection, unsafe tool execution, unauthorized data retrieval, toxic or non-compliant output, identity misuse and cross-application privilege escalation. Nexvora Intelligence models runtime firewall and transaction inspection solutions as representing roughly 35–••% of 2025 spending in the category.

Governance of agentic workflows is emerging as the next strategic battleground. As organizations shift from assistant-style deployments to multi-step autonomous task execution, security teams require policy controls that define what an agent may access, which actions require approval, how decisions are logged, and when workflows must be interrupted. This is driving convergence between security posture management, identity, observability, compliance management and workflow orchestration vendors.

Nexvora Intelligence developed this market opening using proprietary demand modeling, vendor segmentation, enterprise security budget analysis, deployment pattern assessment and bottom-up revenue triangulation across relevant software control categories.

Market sizing reflects modeled estimates only and incorporates spending on posture management, runtime firewalls, testing, policy enforcement, monitoring and governance solutions purpose-built for autonomous software environments.

Forecast ranges account for adoption uncertainty, enterprise rollout velocity, regulatory pressure, platform consolidation and the pace at which autonomous workflows move from pilot deployments into production environments.

All figures are Nexvora Intelligence modeled estimates and should be interpreted as directional planning ranges rather than externally sourced statistics.
