Best Small Business Application Control Software

Airlock Digital is an application control solution that enforces a Deny by Default security posture. It enables organizations to define trusted applications, scripts, libraries, and processes at a granular level using file hash, path, publisher, or parent process. Only those explicitly defined as trusted are allowed to execute. The platform supports Windows, macOS, and Linux systems, including legacy operating systems and operational technology (OT) environments. Airlock Digital includes allowlisting and blocklisting capabilities, integrated file reputation checks via VirusTotal, and detailed logging for audit and compliance. Exception management is supported through features such as rule-based overrides and time-bound One-Time Passwords (OTPs). Centralized policy management allows consistent enforcement across large and distributed environments. The platform is available as an on-premises deployment, in the cloud, or as a managed hosted service.

ManageEngine Endpoint Central enforces comprehensive application control across every managed endpoint ensuring only trusted, approved applications can execute while blocking unauthorized, untrusted, and potentially harmful software before it runs. A default-deny approach with intelligent allowlisting prevents malicious applications, unauthorized tools, and unapproved software from executing across the endpoint fleet significantly reducing the risk of ransomware, malware, and insider threats. Administrators can create and manage allowlists and blocklists centrally, with granular policy controls targeting specific device groups, user roles, and organizational units. Application discovery provides complete visibility into all software running across the network before enforcement, ensuring legitimate business applications are accounted for and policies are built on real usage data rather than assumptions that could block productivity or leave gaps in security coverage.

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.

Securden Unified PAM is a privileged access security solution that lets you discover, centrally store, organize, share, manage, and keep track of all privileged identities, passwords, keys, documents, and other identities. It helps you establish a centralized password management system, automate management with approval workflows, control ‘who’ can access ‘what’, monitor, and record all access to critical IT assets, and enforce password security best practices. The major modules of Securden Unified PAM are password management, privileged account management, secure remote access, application control, endpoint privilege management, privileged session management, and SSH key management. The platform supports compliance with NIS2, DORA, NIST, PCI-DSS, HIPAA, and ISO-IEC 27001. Installation typically takes only a few minutes, and a complete production-ready PAM can be achieved in less than a month with Securden Unified PAM.
