BeforeBreach Intelligence serves as a robust External Attack Surface Management (EASM) tool designed to offer ongoing insights into an organization’s publicly accessible assets and security vulnerabilities. The platform identifies and keeps track of domains, subdomains, IP addresses, cloud resources, and exposed services to uncover possible access points that malicious actors might take advantage of. It effectively identifies various risks, including exposed administrative interfaces, compromised credentials, improperly configured cloud resources, vulnerable services, and critical Common Vulnerabilities and Exposures (CVEs). What sets BeforeBreach apart is its approach to prioritizing risks based on their potential for real-world exploitation as opposed to relying solely on traditional severity ratings, thus allowing security teams to concentrate their efforts on the most significant threats. Each identified risk is not only validated but also supplemented with technical details, information about affected assets, and straightforward remediation recommendations. The platform ensures a continuously updated inventory of assets, effectively tackling blind spots while providing real-time notifications, which empowers organizations to take proactive steps in minimizing their external attack surface and thwarting potential breaches before they happen. Additionally, this proactive management fosters a culture of security awareness, enabling teams to stay ahead of emerging threats.

Panaseer's continuous control monitoring platform is a powerful tool that can monitor and monitor all aspects of your organization. It provides trusted, automated insight into the organisation's security and risk posture. We create an inventory of all entities in your organization (devices and apps, people, accounts, and databases). The inventory identifies assets that are missing from different sources and identifies security risks. The platform provides metrics and measures that will help you understand your compliance and security status at all levels. The platform can ingest data from any source, cloud or on-premises. Data can be accessed across security, IT, and business domains using out-of-the box data connectors. It uses entity resolution to clean and normalise, aggregate and de-duplicate this data. This creates a continuous feed with unified assets and controls insights across devices and applications, people, database and accounts.

Quickly identify, prioritize, and address threats to your security assets within minutes. Leverage Cyber asset attack surface management to enhance your visibility and oversee your entire cybersecurity inventory effectively. Uncover vulnerabilities across all your assets while bridging the gaps often left by traditional agent-based management solutions. Identify weaknesses in servers, clients, cloud environments, and IoT devices seamlessly. Octoxlabs utilizes agentless technology to amplify your visibility, offering over 50 API integrations. You can monitor the status of your installed application licenses at any time, including the number remaining, those already used, and renewal dates, all from a centralized location.
