Best Attack Surface Management Platforms for Linux

ThreatLocker is a Zero Trust Platform that prevents cyber threats by blocking unknown applications, enforcing least privilege, and controlling what can run across your environment. Using Allowlisting, Ringfencing, Network Control, and more, ThreatLocker stops ransomware, zero-day attacks, and unauthorized activity before execution, rather than relying on detection after the fact. Built for modern IT and cybersecurity teams, the platform delivers centralized visibility and policy management across endpoints, users, and applications. ThreatLocker reduces attack surface, limits lateral movement, and supports compliance with detailed audit logs. With fast deployment, a large built-in application library, and streamlined approvals, organizations can strengthen security while minimizing operational overhead and maintaining business continuity.

Panaseer’s continuous controls monitoring platform sits above the tools and controls within your organisation. It provides automated, trusted insight into the security and risk posture of the organisation. We create an inventory of all entities across your organisation (devices, apps, people, accounts, databases). The inventory highlights assets missing from different sources and where security controls are missing from assets. The platform equips you with metrics and measures to understand your security and compliance status at any level. The platform ingests data from any source in the cloud or on-premises, across security, IT and business domains through out-of-the-box data connectors. It uses entity resolution to clean, normalise, aggregate, de-duplicate and correlate this data, creating a continuous feed of unified asset and controls insights across devices, applications, people, databases and accounts.
