We were founded to protect and defend our collective privacy from exploitation. Together, our founders laid the groundwork for a revolutionary new approach to data security in response to advances in quantum computing. Via strategic investments in cutting-edge quantum hardware companies and exclusive partnerships with premier global research institutes and U.S. national labs, we have amassed multiple quantum entropy sources to create high-quality random keys at scale. As a result of this technology and its revolutionary Everlasting Security protocol, we have developed the only cryptographic solution capable of securing information indefinitely with mathematical proof as evidence.

At Teleskope, we believe that data security and privacy is shifting left, and should be automated and enforced from within at the earliest stages. We are building a developer-first data security platform that provides companies with complete and actionable visibility into their continuously growing data.

At CloudSEK, we combine the power of Cyber Intelligence, Brand Monitoring, Attack Surface Monitoring, Infrastructure Monitoring and Supply Chain Intelligence to give context to our customers’ digital risks.

All software contains security flaws, and there are more bad guys attacking the companies that depend on this software than there are good guys defending them. According to PBS, upwards of 209,000 cybersecurity jobs in the U.S. are unfilled, and postings are up 74 percent over the past five years. This number will rise dramatically over the next 10 years as technology trends like public clouds, enterprise mobility and IoT make our businesses and lives more vulnerable to attackers. So who will meet these security demands? Bugcrowd is the premier marketplace for security testing on web, mobile, source code and client-side applications. Taking the leads of Facebook, Paypal and Google's crowdsourced bug bounty programs, we've developed a platform and community that combines a proprietary vulnerability reporting platform with the largest crowd of security researchers on the planet.

Our platform enables us to run 1000+ of (ML-based) scans and tests on potentially 1000+ of clients in parallel, without requiring the installation of an internal agent. We provide continuous, real-time insight into the attack surface of our clients and find critical vulnerabilities that could result in million-dollar data breaches or ransomware attacks.
