Tonic Security, a Tel Aviv-based cybersecurity start-up, has just come out of stealth mode with $7 million in seed funding. Their goal is straightforward: help organizations respond faster and smarter to vulnerabilities by making security alerts more actionable.
Security teams today face an overwhelming flood of alerts from multiple tools. This overload makes it nearly impossible to prioritize effectively, causing real risks to slip through unnoticed. Attackers take advantage of this chaos, exploiting vulnerabilities that should have been addressed.
Tonic Security tackles this by adding meaningful context to every alert. Their platform combines domain-specific AI agents with a proprietary Data Fabric that integrates threat intelligence and organizational data—like tickets, documents, emails, and messages. This approach helps teams quickly assess the business impact, operational dependencies, and the likelihood of a vulnerability being exploited. The result? Clear guidance on which vulnerabilities demand immediate attention and which can wait.
Leadership with Real-World Experience
The company is led by CEO Sharon Isaaci, CPO David Warshavski, and CTO Greg Ainbinder—each bringing deep industry expertise. Isaaci’s background includes executive roles at Sygnia and serving as CISO and Senior Intelligence Officer at the IDF. Warshavski headed the Red Team and Enterprise Security at Sygnia, while Ainbinder contributed to AI development at intelligence unit 8200.
This leadership team has firsthand experience with the problem they’re solving. Isaaci recalls how many data breaches at Fortune 500 companies were preventable if exposures had been prioritized correctly. Their frustration with wasted efforts and missed signals led them to create Tonic Security.
Why This Matters for Management
- Better Prioritization: Security teams can focus on vulnerabilities that pose real business risks instead of chasing every alert.
- Faster Remediation: Context-rich alerts lead to quicker decision-making and more effective responses.
- Resource Optimization: Reduce alert fatigue and improve security team efficiency.
For managers overseeing security operations, tools like Tonic Security offer a practical way to reduce noise and improve the quality of vulnerability management decisions.
