10 Cool Agentic Security Startups In 2026

Here are 10 startups that are on our radar in segments including agentic SOC, agent-powered security remediation and AI agent protection.

Agentic Security Startups To Know

Following the rise of the AI agent, numerous promising startups have rapidly launched new agentic security platforms into the market, covering the nascent technology from a number of different cybersecurity angles. On the one hand, a major focus for many of the new startups is around bringing AI agents into the Security Operations Center (SOC), leveraging the newly available capabilities to autonomously handle many of the tasks that once required a human security analyst. These agentic SOC startups are looking to address many of the biggest challenges of cyber defense—including alert fatigue and investigation overload—in a way that was never possible prior to the advent of GenAI and AI agents.

Meanwhile, another group of startups are leveraging agentic technology to take on a different set of problems within cybersecurity: Remediation of vulnerabilities and other persistent security risks. These emerging vendors are looking to do more than just discover vulnerabilities and exposures by actually deploying fixes—but in an autonomous, agent-powered fashion.

Finally, to complement the focus on agentic cyber defense, a number of startups are also delivering protection for the AI agents themselves. These startups are aiming to ensure that agentic doesn’t become the next major target for threat actors, through boosting visibility and providing a variety of essential controls.

Notably, many agentic security startups in 2026 are focused on working with VARs, MSSPs and other channel partners even from an early stage—a recognition of the trusted adviser role that the channel is continuing to play in the AI era.

What follows are the details on 10 cool agentic security startups you should know in 2026.

7AI

Founded: 2024

CEO: Lior Div

7AI delivers a platform that deploys autonomous AI agents to handle critical “non-human” security operations tasks such as alert triage, investigations and incident response, according to the company. The agents leverage dynamic reasoning capabilities in order to adapt to various scenarios and eliminate false positives—ultimately enabling faster responses within security operations. In August 2025, the startup unnveiled a partnership with technology services provider giant DXC that combines DXC’s security operations capabilities with autonomous AI agents from 7AI. Then in December, 7AI announced raising $130 million in Series A funding led by Index Ventures, which brought with it a $700 million valuation.

Dropzone AI

Founded: 2023

CEO: Edward Wu

Dropzone AI provides SOC teams with “armies” of AI agents that can take over routine triaging and investigation of alerts, according to the company. The startup said in January it has already gained massive momentum with its AI SOC Analyst platform, with adoption so far by more than 300 enterprises. Key capabilities for the AI-native platform include autonomously handling alerts with “human-level” reasoning, providing a substantial offloading of alert volume with high accuracy, Dropzone AI said. Crucially, Dropzone AI has focused heavily on channel partnerships, including with MSSPs and VARs, according to the startup. The company is backed by a $37 million Series B funding round, which was raised in July 2025 and led by Theory Ventures.

Furl

Founded: 2022

CEO: Derek Abdine

Furl is looking to boost the usage of agentic capabilities within the space of security remediation, with a focus on autonomously executing the actions needed to remediate vulnerabilities. The goal is to narrow the gap between detection of security vulnerabilities and resolution, through deploying agentically powered fixes that leverage the context from real-world systems, according to the startup. That’s in contrast to existing tools that mainly serve to generate additional alerts or tickets, without providing remediation, Furl said. In January, the company disclosed it has raised $10 million in seed funding led by Ten Eleven Ventures, with other participating investors including from Rapid7 CEO Corey Thomas.

Noma Security

Founded: 2023

CEO: Niv Braun

Noma Security offers a platform for controlling AI and agentic risk with a major focus on providing continuous discovery for AI assets and agents. The platform provides a full AI inventory through automatically discovering where AI applications and agents are being built, as well as determining which data and systems they can access, according to Nick Crouch, senior director of channel and alliances at Noma. Other key capabilities include AI security posture management and risk prioritization as well as AI runtime protection, the company said. In July 2025, Noma Security raised $100 million in a Series B round of funding led by Evolution Equity Partners.
