Tonic Security Emerges from Stealth with $7M to Revolutionize Cyber Risk Management
In a bold step toward addressing the growing challenges of cybersecurity, Tonic Security, a startup designed to help security teams navigate the overwhelming noise and complexity of modern cyber threats, has emerged from stealth mode with $7 million in seed funding. The company’s innovative AI-powered platform is transforming how organizations manage vulnerabilities by aligning and interpreting fragmented data from IT and security tools, adding actionable context to every finding. This enables security teams to prioritize and remediate risks faster, reducing exposure windows and enhancing overall protection.
The seed round was led by Hetz Ventures, with participation from Vesey Ventures and prominent angel investors from the cybersecurity industry. These backers recognize Tonic’s potential to address one of the most pressing issues in cybersecurity: the inability of teams to keep pace with an ever-expanding attack surface.
Led by seasoned cybersecurity experts Sharon Isaaci (CEO), David Warshavski (CPO), and Greg Ainbinder (CTO), Tonic tackles a critical pain point for security teams. As organizations adopt more tools and technologies, they are inundated with endless alerts, findings, and assessments. This flood of information often leaves teams unable to proactively address the exposures that truly matter before threat actors exploit them.
Solving the Root Cause of Cybersecurity Failures
“Before founding Tonic, I was increasingly frustrated with the recurring pattern I observed,” said Sharon Isaaci, who brings decades of experience as a CISO, incident responder, and trusted advisor to Fortune 500 companies. “Time and again, I saw breaches that could have been prevented if only the right vulnerabilities had been prioritized and fixed in time. Unfortunately, many exposures were mis-prioritized or overlooked entirely, giving adversaries the upper hand.”
This frustration inspired Isaaci and her team to create Tonic. “Our mission is to address the root cause of these failures,” she explained. “Tonic introduces the first context-driven Exposure Management Platform, which eliminates the chaos caused by dozens of fragmented tools. By providing clarity, focus, and business-relevant context, we empower security teams to proactively protect their organizations.”
How Tonic Works: AI-Powered Contextualization
At the heart of Tonic’s platform is its proprietary domain-specific AI agents and Data Fabric, which harmonize and contextualize data from various sources, including threat intelligence feeds and unstructured organizational knowledge like tickets, documents, emails, and messages. By aggregating and analyzing this information, Tonic equips users with insights into the potential business impact, operational dependencies, accountability, likelihood of exploitation, and remediation feasibility of each exposure.
Armed with this actionable context, security teams can:
- Prioritize vulnerabilities based on their actual business impact.
- Dramatically reduce noise from false positives and irrelevant alerts.
- Accelerate remediation efforts by focusing on what truly matters.
Early adopters of Tonic’s platform have already seen remarkable results:
- A 50% decrease in Mean Time to Remediate (MTTR) for business-critical exposures.
- A 20% reduction in time spent per employee per week contextualizing findings and triaging alerts.
- A 90% reduction in exposures requiring remediation, thanks to smarter prioritization.
Real-World Impact: What Customers Are Saying
Industry leaders are already praising Tonic’s ability to streamline and enhance cybersecurity operations.
“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 assess its potential risk to the business. With Tonic, it takes minutes. The platform’s ability to provide clear, actionable insights has transformed how we approach vulnerability management.”
Global enterprises, including Fortune 500 companies, are trusting Tonic to:
- Reduce the exposure window for remediating vulnerabilities and triaging alerts.
- Eliminate wasted time on false positives and unnecessary tool pivots.
- Enhance collaboration between security, IT, and business stakeholders.
- Move beyond technical visibility and generic security scores to gain a business-led perspective of their security posture.
Backed by Visionary Investors
“Security teams are drowning in data but starving for context,” said Pavel Livshitz, General Partner at Hetz Ventures. “What stood out about Tonic is their ability to surface what actually matters to the business by applying AI in a pragmatic and operational way. Tonic helps organizations transition from reactive firefighting to intelligent preemption—a shift that represents the future of cybersecurity. That’s exactly the kind of innovative thinking we support.”
A Team with Proven Expertise
The leadership team behind Tonic brings unparalleled expertise in cybersecurity and artificial intelligence. Prior to founding Tonic, Sharon Isaaci served as an executive at Sygnia, a leading incident response and cybersecurity consulting firm, and previously held roles as CISO and Senior Intelligence Officer in the Israeli Defense Forces (IDF). David Warshavski, also an executive at Sygnia, led its Red Team and Enterprise Security department, working closely with Fortune 500 CISOs to build resilience. Greg Ainbinder, who rounds out the leadership trio, held senior positions in Israel’s elite intelligence Unit 8200, where he founded its AI department and Secure Cloud Center.
A New Era of Intelligent Cybersecurity
As cyber threats grow in sophistication and scale, organizations need solutions that go beyond traditional vulnerability management. Tonic Security is redefining the landscape by empowering security teams with the context and clarity needed to act decisively. By bridging the gap between fragmented tools and actionable insights, Tonic is helping organizations stay ahead of adversaries and protect what matters most.
With its groundbreaking platform and strong financial backing, Tonic Security is poised to become a leader in the cybersecurity space, enabling businesses to move from reactive defense to proactive protection. In an era where cyber risk is a top concern for organizations worldwide, Tonic’s mission to slash cyber risk through agentic exposure management couldn’t come at a better time.
