Israeli Cybersecurity Start-Up enSilo Emerges from Stealth Mode to Tackle Exfiltration Prevention
enSilo Launches into Global Security Arena with a Unique Perspective on the Cyber Kill Chain

Given the constant and chronic nature of today’s cyber-attacks, enSilo reverses the traditional perspective on threats by looking at the end of the kill chain, where exfiltration occurs, rather than the beginning. enSilo’s application agnostic platform analyzes communication requests at the operating system (OS) level to enforce the anti-exfiltration policies already on connection establishment requests. The company’s solution enables organizations from all verticals to prevent business critical data from being stolen from the organization by advanced attackers even in the face of the persistent, chronic, advanced attacks. With its virtual patching against targeted attacks, enSilo enables employees to continue working, even with the endpoint is infected.

As a seasoned security professional, CEO of enSilo, Roy Katmor, is known for his ability to combine strong technical knowledge with proven sales and marketing capabilities. Prior to enSilo, Katmor led Akamai’s security strategy as the company’s Sr. Director, Security Product Strategy, where he focused on positioning Akamai as a security innovator during a transitional time for the company. In addition, Katmor managed Imperva’s data security technical product management and architecture.

“The traditional defense-in-depth approach against advanced targeted threats has resulted in too many alerts for security professionals to handle. The constant infiltration nature of today’s threats led organizations into a “Whack-a-Mole” state where they are pre-destined to lose the game,” said Roy Katmor, CEO of enSilo. “By reversing the cyber kill chain defense model, enSilo is able to prevent – in real time – only active exfiltration attempts by targeted attackers. Thus, enSilo generates only one alert per one active threat while allowing organizations to continue operating as usual.”

“Organizations today are under constant and chronic attack at some level. All are faced with the real threat of their most valued resources being stolen through one or more of a variety of sophisticated methods. Defending against data exfiltration is at the core of security prevention and should be considered for any environment to mitigate these threats while maintaining “business as usual” operations,” said David Monahan, EMA.

Ronen Nir, General Partner at Carmel Ventures who joined the Company’s board of directors added: “We at Carmel Ventures, are excited to partner with the exceptional founding team of enSilo that brings a unique approach to the growing Advanced Persistent Attack problem.”

About enSilo
enSilo offers a real-time exfiltration prevention platform. The company was founded on the recognition that targeted attacks are similar to chronic diseases where organizations that have made responsible and sustained investments in attack detection continue to be compromised. In the same way chronically-ill patients are treated to control the disease and increase longevity, organizations must deal in real-time with a persistently compromised network. To that effect, enSilo prevents the consequences of an advanced targeted attack, namely, the theft of valuable data. enSilo has developed a platform which accurately distinguishes legitimate connections from malicious ones, already on initial connection establishment. Our solution provides virtual patching against advanced targeted threats enabling employees to keep working as usual while a device compromise is resolved.

The company is headed by highly respected security veterans from leading private and public sector companies, including Imperva, Akamai, EMC and Rafael. enSilo is financially-backed by Carmel Ventures.
