Tonic Security, a cybersecurity startup focused on exposure management, has emerged from stealth with $7m in seed funding to support its mission of helping organisations cut through alert fatigue and remediate cyber threats more effectively.
The seed round was led by Hetz Ventures, with additional backing from Vesey Ventures and several high-profile angel investors with deep expertise in the cybersecurity sector.
The company offers a context-driven exposure management platform powered by artificial intelligence. Tonic’s platform harmonises data from fragmented IT and security tools, aligning them with business priorities to help teams prioritise vulnerabilities and exposures. By providing rich contextual insight, the platform allows teams to act swiftly on what matters most, eliminating false positives and reducing remediation time.
Tonic plans to use the new capital to further develop its proprietary AI capabilities, expand its platform’s functionality, and grow its customer base among enterprise clients. The platform already claims measurable results, including a 50% drop in mean time to remediate (MTTR) for critical issues, a 20% reduction in weekly time spent triaging alerts, and a 90% cut in exposures needing remediation.
The startup was founded by cybersecurity veterans Sharon Isaaci, David Warshavski and Greg Ainbinder. Isaaci previously served as an executive at cybersecurity consultancy Sygnia, and also held senior roles as CISO and intelligence officer in the Israeli Defence Forces. Warshavski also worked at Sygnia, leading its Red Team and enterprise security services, while Ainbinder founded the AI department within Israel’s elite Unit 8200.
“Tonic is addressing the root cause of the problem, by introducing the first context-driven Exposure Management Platform that eliminates the cacophony caused by dozens of disparate tools, and provides the clarity, focus and business context security teams need to proactively protect their organizations,” said Tonic Security CEO Sharon Isaaci.
“Tonic is a game-changer,” said Mark Fournier, CIO and CISO of the United States Senate Federal Credit Union. “It used to take days to identify an exposed asset and understand the potential risk to the business if exploited. With Tonic it takes minutes.”
Hetz Ventures general partner Pavel Livshitz added, “Security teams are drowning in data but starving for context. What stood out with Tonic is their ability to surface what actually matters to the business by applying AI in a pragmatic and operational way. Tonic helps organisations move from reactive firefighting to intelligent preemption. That’s the kind of innovative thinking we back.”
