Sweet Security announced a $33 million Series A on March 6, 2024, about six months after emerging from stealth with a $12 million seed round. Evolution Equity Partners led the financing, with Munich Re Ventures and Glilot Capital Partners participating. The company said it would use the new capital to expand its U.S. go-to-market efforts and develop its cloud runtime security technology.
What Sweet Security raised and who invested
The $33 million Series A was led by Evolution Equity Partners. Munich Re Ventures and existing investor Glilot Capital Partners also participated. SecurityWeek reported that the Series A brought Sweet’s funding to $45 million including its seed round (SecurityWeek, March 6, 2024).
How the financing followed Sweet’s launch
Sweet Security was founded in Tel Aviv in January 2023. In August 2023, it emerged from stealth with a reported $12 million seed round backed by Glilot Capital Partners and angel investors. The Series A announcement followed about six months later.
What Sweet Security’s product did at the time
In its March 2024 announcement, Sweet described a cloud runtime security suite built around a patent-pending eBPF-based sensor. The company said the sensor identified anomalies across applications, networks and non-human identities, and that the suite covered detection and response, vulnerability management, runtime posture enhancement and non-human identity management. These are descriptions of the vendor’s product, not independent test results (Sweet Security announcement reproduced by VentureBeat, March 6, 2024).
#1 Best Overall
The underlying idea is to observe activity as workloads run, rather than relying only on information gathered through external cloud APIs. Sweet’s announcement quoted wording attributed to a November 2023 Gartner report: “Focus more on the runtime; get events directly from the runtime environment, not just via third-party APIs.” The quotation appears in Sweet’s release; it is not a direct review of Sweet’s product.
Why Sweet said it was raising the money
Co-founder and chief product officer Eyal Fisher told SecurityWeek that the seed funding helped the company open a U.S. office and enter the U.S. market. He said the Series A would support further U.S. go-to-market activity and product development. Fisher also said the company had found the market “more than ready” (SecurityWeek, March 6, 2024).

What happened after the Series A
Sweet later announced a $75 million Series B on November 12, 2025, led by Evolution Equity Partners. The company said the round brought its total funding to $120 million. It also reported sixfold annual recurring revenue growth and tenfold growth in enterprise customers over the preceding year; those growth figures are company-reported and were not independently audited in the announcement (Sweet Security, November 12, 2025).
On July 29, 2026, Sweet announced runtime blocking capabilities for agentic AI. The company said the product can terminate unauthorized agent tool calls and sessions, stop sensitive information from leaving through an agent, and block prompt injection in real time. Sweet also reported analyzing more than one billion runtime events daily. These are vendor-announced capabilities and a company-reported event volume, not independent evaluations (Sweet Security via GlobeNewswire, July 29, 2026).
