Act Security Unveils Groundbreaking Cloud Security Platform

Act Security, an innovative company in the field of cloud security, has officially launched its action-centric platform and secured $60 million in funding. Established by a team from Medigate, Act Security focuses on mitigating risks at the infrastructure level by addressing access-related vulnerabilities that lead to security breaches.

In today’s digital landscape, the role of artificial intelligence is paramount. Traditional security protocols, which often relied on manual fixes like patching vulnerabilities, have become ineffective. This approach inundated security teams with ever-increasing tables of misconfigurations. Recognizing this gap, Act Security's platform aims to systematically reduce exploitable access paths across cloud infrastructures, setting clear boundaries for human users, workloads, and AI agents.

Funding and Founding Vision

Since its inception in 2025, Act Security raised $20 million in seed funding, led by Team8 and Bessemer Venture Partners. This was followed by a $40 million Series A funding round, driven by Notable Capital and other notable investors. Jonathan Langer, co-founder and CEO of Act Security, highlights that nearly 97% of cloud access permissions are often inactive, creating unnecessary risk. The rapid advancement of AI technologies has exacerbated this issue, as these agents exploit dormant access paths faster than traditional teams can manage.

Langer underscores that with AI like Anthropic's Claude Mythos operating at lightning speed, organizations face a heightened risk, prompting the need for reformed cloud security measures.

Addressing Access Sprawl

The platform is designed to combat the issue of access sprawl found in many organizations. It not only cleans up existing access but also prevents new vulnerabilities from arising. By continuously validating and tightening boundaries, it ensures that unauthorized access remains at bay, especially by AI agents that operate without the context human intervention provides.

Act Security’s approach is a paradigm shift in how organizations handle access permissions. By implementing deterministic boundaries, the platform permits only necessary access for each agent while maintaining a focus on safeguarding human and workload interactions. This proactive stance is designed to facilitate the secure integration of AI technologies into existing infrastructure.

Compliance and Future Prospects

One of the key features of the platform is its ability to enforce compliance continuously. This includes mapping security controls to requirements such as NIST 800-53, PCI DSS, and HIPAA, ensuring organizations remain audit-ready. As cybersecurity threats evolve, Act's platform positions itself as a forward-thinking solution, proactively addressing vulnerabilities before they can be exploited.

Liran Grinberg, co-founder and Managing Partner at Team8, commends Act Security for acknowledging the pressing issue of access. He believes that with AI exploiting vulnerabilities at unprecedented speeds, the necessity for immediate implementation of such solutions has never been more critical.

By providing organizations with a pathway to structural security, Act Security is poised to lead the charge against the rising tide of sophisticated cyber threats. With significant funding backing their vision, Act Security stands at the forefront of transforming cloud safety as we know it.
