CyberOwl develops an innovative early warning system for attacks through real-time monitoring of high-value targets for malicious behavior. The technology, based on research shortlisted for the Lloyd’s Science of Risk Prize 2015, is aimed at addressing the challenges of increasingly anonymous and persistent threats to rapidly-expanding global networks, particularly in the wake of Smart Cities and the Internet of Things.
The system raises early warning on network assets for possible undesirable activity, by applying a Bayesian-based framework to systematically analyze indicators associated with early stages of such activity. This approach dramatically reduces the processing overheads of monitoring.
The benefits to the security operation include scalability to networks exceeding 1 billion devices, providing earlier visibility of risk and improving prioritization and decision-making in deploying countermeasures. CyberOwl is developing its minimum viable product and is looking for two or three strategic industry design partners for validation, verification, and further development.
The ideal design partner would provide access to real-world security problems in a large network, high-volume data environment. CyberOwl was founded on 2016 and is headquartered in London, England..

“We work to protect your business from criminal Interference” Unicus, with the UOS hardened Operating System is the only integrated & effective defence against the threats facing RTC services. Communication patterns have changed.
Real-Time Communications (RTC) services moved to IP service delivery. IP based phone system are now found in virtually all major companies and IP is becoming the dominant service delivery mechanism with SIP trunks growing fast and all major service providers committed to switching from legacy technology to IP for all connections.
Add to this the benefit of using IP for remote connections to enable connectivity for remote and roaming users, then all RTC services, voice and video calls, Instant Messaging and Presence (tracking the availability of colleagues) migrate to the IP world. Just as the growth of email and web lead to the development of new attacks and security threats, moving RTC to IP networks has had the same result.
Without adequate security controls, IP based RTC systems (including IP-PBX from well-known vendors and the growing range of Unified Communications Services) are all open to attack. These attacks include denial of service (DoS) attacks, loss of confidential data and potentially expensive fraud attacks.
The cyber security products developed for the first wave of Internet applications do not adequately protect IP based RTC services. These products can hamper the successful deployment of RTC.
RTC services face threats at multiple levels, network, application and content. Effective security controls must address the threats at each level.

Authentication based only on one factor – the password – cannot be considered reliable enough for systems with a high level of security requirements. Using several factors in the authentication system simultaneously significantly increases the system’s level of protection against unauthorized access.
Many companies offer their solutions for implementing multifactor authentication, but their problem is that they are bureaucratic monsters with all the predictable consequences: poor communication and subpar service; cumbersome, inconvenient and inflexible products; unavailability of the current information and lack of means to obtain it promptly. Besides, these companies are monopolists; they bill their customers for huge amounts after completing the stage of negotiations with each client, without publically disclosing their prices.
Protectimus aims to offer the best solution in the sphere of two-factor authentication in terms of price and ease of use and ensure a high level of quality and system reliability.. .
