Copperhelm Agentic Cloud Security

Copperhelm is an Israeli cybersecurity startup that emerged from stealth in April 2026 with a USD 7 million seed round led by TLV Partners. It addresses the gap between the many findings that cloud security tools raise and the real risks that teams have time to fix.

The platform is an agentic and agent-free cloud security system. Specialized AI agents analyze network and systems, simulate adversaries, validate real risk and execute remediation such as creating WAF rules or patching images. A Context Lake gives agents architectural context across cloud accounts, and three human-oversight modes keep security teams in control.

• Risk validation: confirms which cloud findings are exploitable to reduce false positives.
• Agentic remediation: patches, prevents, contains or hands off issues to teams.
• Human oversight modes: Human Acts, Human in the Loop and Human on the Loop.
• Safety controls: policy rules, blast radius analysis and one-click rollback.
• Context Lake: gives AI agents architectural context across cloud accounts.
• Adversary simulation: specialized agents test network and systems paths.

Banks and large enterprises in Vietnam running multi-account AWS can prioritize exploitable findings. Security teams with small staff can let agents apply WAF rules for newly disclosed vulnerabilities under approval.

Cuts false positives by validating which cloud findings are real risks.

Executes remediation such as WAF rules and image patching when a vulnerability is disclosed.

Keeps humans in control through three oversight modes with blast radius analysis and one-click rollback.

Works without installing agents on workloads.

Cloud security teams drown in alerts while exploits appear within hours of disclosure, driving interest in autonomous, agent-based remediation. Vietnamese enterprises moving workloads to AWS and other clouds face the same triage backlog.

Seed round of USD 7 million announced 23-24 April 2026, led by TLV Partners with ToDay Ventures, Icon and SaaS Ventures Israel. Founders include Shimon Tolts as CEO.
