Qevlar AI turns security operations into a self-improving defense system. It investigates every alert across your entire security stack and turns each outcome into intelligence that strengthens response, detection engineering, threat hunting, and vulnerability management. Every case compounds into knowledge the next one can use, so your defense gets harder to attack the longer it runs. Live in production in 1,500 companies globally. Are you next?

Securing the clinical environment requires a new security strategy and coordinated approach as IT, OT, IoT and physical systems converge and the threat of bad actors exploiting vulnerabilities across new and old infrastructure is increasing. IT also requires detailed knowledge of each and every medical device, their proprietary protocols, and a comprehensive understanding of medical workflows. In a network with hundreds of different device types, thousands of devices from different manufacturers, and a mix of protocols and operational parameters it can be overwhelming to protect. Healthcare needs a solution that covers the entire risk spectrum they face while ensuring the usability of these devices without compromising security requires a specialized approach for healthcare. Medigate gives you the confidence to see, secure, and manage all of the devices connected to your network and turn the associated data into a powerful resource. It means the end of any compromise between security and usability – put simply, it allows you to connect with confidence

Activeweave was co-founded in late 2005 by Jean Sini and Marc A. Meyer. It was acquired in 2008 by Buzzlogic. It currently offers consumers two distinct services, both in public beta: the popular browser add-on BlogRovR (over 300,000 registered users) and Stickis. Stickis, launched in November 2006, primarily focuses on tight-knit communities, and lets its users collaborate by annotating web pages as they browse. It also enables users to discover, read and comment on their peers’ annotations, either in-place or through a searchable, centralized repository that exposes the shared accumulated knowledge to participants in a form equivalent to a multi-author blog. BlogRovR, launched in April 2007, helps individuals manage the attention they pay to massive amounts of information hosted by blogs and mainstream media. Thus it participates in stemming the potential attention crisis caused by the accelerated growth in the quantity of content available for consumption online. BlogRovR exploits the same underlying technology as Stickis to continuously overlay stories, contextually relevant to the web page currently being viewed, right into the browser. It allows each individual user to select blogs and mainstream media sources they trust, and automatically picks relevant stories from those sources, as well as closely related sources.
