Tonic Security, a cybersecurity startup focused on eliminating noise and inefficiency in threat response, has emerged from stealth with a $7 million seed funding round. The funding, led by Hetz Ventures and joined by Vesey Ventures along with high-profile angel investors from the cybersecurity space, will help Tonic scale its AI-driven Exposure Management Platform.
At the core of Tonic’s mission is solving one of cybersecurity’s most persistent problems: security teams are overwhelmed by disconnected data, redundant alerts, and unclear prioritization. The platform unifies and contextualizes fragmented signals from IT and security tools, helping teams cut through the clutter to identify and act on the threats that matter most.
The company is led by industry veterans Sharon Isaaci (CEO), David Warshavski (CPO), and Greg Ainbinder (CTO) — all with deep roots in both enterprise cybersecurity and military-grade defense operations. Their collective experience shaped Tonic’s unique approach to threat exposure: proactive, contextual, and AI-augmented.

“Before founding Tonic, I consistently saw a pattern—major breaches often stemmed from known vulnerabilities that were overlooked or misjudged in priority,” said Isaaci. “These exposures weren’t missed due to lack of tools or visibility, but because defenders couldn’t keep pace with adversaries.
That better way is what Tonic calls a context-first approach. By using proprietary AI agents and a domain-specific Data Fabric, the platform doesn’t just surface alerts—it enriches them. Tonic pulls insights from unstructured data sources like tickets, emails, and internal documentation to provide a 360-degree view of each exposure. This enables teams to understand business impact, technical dependencies, risk of exploitation, and resolution pathways within minutes.
Early adopters of the platform benefits:
50% reduction in mean time to remediate (MTTR) high-priority vulnerabilities.
20% less time spent weekly by employees triaging and contextualizing findings.
90% decrease in unnecessary remediation work caused by noise or false positives.
“Tonic is reconsidering how we approach cybersecurity,” said Mark Fournier, CIO and CISO of the United States Senate Federal Credit Union. “What used to take days—like identifying a risky asset and evaluating its threat potential—now takes minutes.”
Tonic empowers large enterprises, including multiple Fortune 500 companies, to:
Shrink the vulnerability window by speeding up detection and triage.
Eliminate inefficiencies tied to tool overload, false positives, and manual workflows.
Bridge the gap between IT, security, and business teams through shared context.
Move beyond generic risk scores toward business-aligned cybersecurity decisions.

“Security teams are overwhelmed by volume and underwhelmed by relevance,” noted Pavel Livshitz, General Partner at Hetz Ventures. “Tonic stood out by offering operational AI that pinpoints what truly matters. They’re enabling a shift from reactive firefighting to proactive risk mitigation—exactly the kind of solution enterprises need now.”
The founding team brings formidable expertise:
Sharon Isaaci previously served as an executive at Sygnia, advising Fortune 500 clients and formerly held cybersecurity leadership roles in the IDF.
David Warshavski led Sygnia’s Red Team and enterprise security division, where he partnered with large organizations on resilience strategies.
Greg Ainbinder, a former senior officer in Israel’s elite Unit 8200, founded the unit’s AI department and spearheaded its Secure Cloud initiatives.
With its innovative platform, deep technical foundation, and strong market reception, Tonic Security is positioned to become a cornerstone of next-generation exposure management—transforming cybersecurity from reactive protection to intelligent, risk-aware defense.
