In this post we continue to pay down the debt owed to readers of Guardians of the Machine Age: Why AI Security Will Define the Future of Digital Defense. I promised to update the list of vendors on my Substack. Here are the next ten in the list of 37 vendors added to our coverage since March 11.

Arambh Labs builds an agentic AI platform that augments security operations teams by intelligently detecting, investigating, and remediating security incidents. The platform uses agentic intelligence and swarms of AI agents to autonomously analyze findings from across an organization’s entire security ecosystem. It integrates with over 100 tools spanning identity, cloud, endpoint, network, and data security solutions including SIEM platforms, SOAR systems, EDR solutions, NDR systems, IAM platforms, and cloud infrastructure providers.

Armadin builds an AI-powered offensive security platform combining human expertise with advanced technology to defend complex organizations. The platform operates as a continuous, agentic red teaming and remediation solution designed to identify and address security vulnerabilities through autonomous AI agents. The company focuses on offensive security capabilities to combat AI-driven hyperattacks, offering automated penetration testing, red team operations, and vulnerability remediation. The platform answers the core question of organizational security posture by providing unified, scalable, and ongoing offensive assessments that simulate attacker behavior at scale. It announced total funding of $189.9 million on March 10.

Astelia is an AI-native exposure management platform that identifies vulnerabilities that are truly reachable and exploitable within an organization’s environment, eliminating noise from theoretical risks. The platform delivers three primary capabilities: network topology mapping that integrates with infrastructure and network tools to understand the complete network landscape, agentic vulnerability analysis that uses AI agents trained by nation-state-level experts to identify exploitability requirements, and reachability analysis that correlates network topology, asset context, and runtime data to classify which vulnerabilities pose genuine risk.

Ciphero is an early-stage enterprise AI security vendor offering an AI verification layer that monitors, verifies, and governs human and agentic AI interactions. Founded in 2025 by the former Fakespot leadership team, the company focuses on shadow AI visibility, policy enforcement, and data-loss prevention for enterprise AI deployments, and launched from stealth with $2.5 million in pre-seed funding in late 2025.

C1 is an AI-native identity security platform focused on governing access for human, machine, and AI identities. Rebranded from ConductorOne in 2026, the company combines identity governance, just-in-time access, dynamic controls, and automation in a single platform aimed at modernizing legacy identity stacks for cloud and agentic enterprise environments.

CyberAGI is an early-stage offensive security startup developing Excalibur, an AI-native platform for threat modeling, pentest workflow automation, and related security operations use cases. The company promotes a broader vision of building an ‘AI enterprise,’ but its current market presence appears centered on self-serve and private-deployment offensive security tooling, with limited independent public evidence so far on funding or customer scale.

EnforceAuth is a unified enterprise authorization platform that enforces fine-grained policy across infrastructure, applications, data, and AI workloads. The company’s core objective is to solve the fragmentation problem where enterprises operate with disconnected access control systems across different environments. EnforceAuth is specifically designed for AI-driven enterprises, treating AI models, prompts, tools, and agents as first-class security subjects. It controls every AI-agent-to-data and agent-to-agent interaction in real time across any cloud or infrastructure, addressing new security challenges like prompt injection and unauthorized data access by AI systems.

Evoke secures the agentic workforce by providing visibility and control over every agent, action, and connection across enterprises. The platform auto-discovers agents, models, tools, and data sources to eliminate shadow AI. It identifies malicious skills and model context protocols (MCPs), maps attack paths and toxic flows, and remediates over-permissioned agents through threat modeling. The platform detects, prevents, and responds to unauthorized actions by monitoring all prompts, tool calls, and responses, enforcing per-agent policies and detections, and blocking unauthorized actions in real-time. Evoke meets agents where they live through multiple deployment architectures including endpoint agents for local environments, SDK and proxy API integrations for production agents, and browser extensions for SaaS agents. The company was selected for the 2026 CrowdStrike, AWS & NVIDIA Cybersecurity Startup Accelerator and raised $4 million in pre-seed funding.

FlintX provides AI-powered security monitoring and threat detection specifically designed for industrial control systems and operational technology networks across critical infrastructure sectors. The company’s primary mission is to protect critical infrastructure by combining operational technology expertise with artificial intelligence to defend industrial control systems (ICS), SCADA systems, PLCs, and related environments from cyber threats.

Hackerdogs is an early-stage AI-native cyber intelligence vendor that combines attack-surface discovery, OSINT, and cross-domain threat analysis into evidence-backed intelligence briefings for security and executive stakeholders. Founded by former Sumo Logic and LogicMonitor executive Tej Redkar, the company is positioning around autonomous, intelligence-led cyber exposure management, though public third-party evidence on funding and customer scale remains limited.

By next week we should be all caught up. In the meantime order your copy of Guardians here.
