cybernality

We, addoptIO GmbH, are a start-up company from Germany founded in 2021. We make the world a better place by helping individuals, companies and organizations overcome cybersecurity challenges. Speed is an important key to success in order to avoid offering attackers unnecessary targets. That’s why we built cybernality.com. We provide RELEVANT information on cyber defense exactly when it is NECESSARY for you. cybernality is a 360° cybersecurity information service that provides you with topics tailored exclusively to your needs in the quickest and easiest way. Comprehensive cybersecurity search index as a central information hub: We scour the internet for you for the latest cybersecurity information, normalize the data into a standardized format, enrich the data with additional context and make it available in a search index. With the help of professional search options, you can find the right information quickly and easily. Automatic notifications always keep you up to date: Whether you want to be informed about new vulnerabilities in certain products or follow the activities of an APT group, with cybernality you will never miss any relevant news. Automated searches, so-called feeds, keep an eye on our extensive cybersecurity database for you and send you every new result that matches your feed. You can either receive these notifications by email or connect any third-party software, such as ITSM tools, SOAR solutions, vulnerability management systems, etc. via API endpoint. Extensive filters put an end to information overload: In 2022, over 25,000 new vulnerabilities (CVEs) were listed in the National Vulnerability Database (NVD), and the trend is rising. In addition, there are daily reports of successful hacker attacks and activities by advanced persistent threat (APT) groups. Countless sources on the Internet contain important information on cybersecurity topics. All this makes finding information like looking for a needle in a haystack. cybernality offers extensive filters to make your searches as specific as possible. Enriched context makes you 100% effective: Information must be placed in a larger context in order to gain meaning. That is why all entries in our search index are provided with a context that enables you to quickly grasp the meaning of the information, understand the context and find the information quickly. Context means that we classify search results into, for example, security advisories, threat information, hacking attacks, etc. We provide MITRE Att&ck TTPs (Tactics, Techniques, Procedures) that match the vulnerabilities and attacks mentioned, for example. We list the named product details (name, version, platform, CPE string etc.) and manufacturer as well as authors and security researchers. We provide NVD and manufacturer severity information and much more. Central account management for comprehensive teamwork: Successful cybersecurity work is based on effective teamwork. cybernality was designed from the outset to enable heterogeneous and distributed teams to use the platform together. This means you can, for example, manage the various team members and settings centrally, share feeds within the team or send individual feeds to different recipients. Users with admin rights maintain an overview and manage all central settings. Multi-client capability for sophisticated account management: In more complex organizations or for use cases with external end customers, the use of different clients via a central dashboard can be an important function. cybernality allows you to create several “Payment Accounts”, whereby each “Payment Account” can contain any number of subscriptions. The cybernality users are assigned to individual subscriptions by central administrators and remain exclusively within the scope of the respective subscription. It is also possible for a user to be assigned several subscriptions at the same time. This gives you maximum flexibility in structuring your accounts and you can, for example, map group structures with your own cost center management or offer cybernality as a managed service for external customers. In addition, a strict distinction is always made between personal subscriptions and company subscriptions. This means that every user can use cybernality for both private and business purposes independently of each other. Single sign-on for maximum security and user-friendliness: As a cybersecurity startup, we also have high IT security standards for our service. That’s why we only allow third-party identity providers, such as Google or Microsoft, to be used for authentication at cybernality. This not only increases security, but also brings more convenience for you as a user, because you can register with cybernality using your company account or your private Google account, for example. It couldn’t be quicker or easier!
