Pentera Platform vs PurpleSharp

Pentera Platform validates security controls by emulating attacks, helping security teams identify proven exposure and support remediation. Its Core, Surface, and Cloud offerings cover internal networks, external attack surfaces, and cloud environments; listed coverage also includes web applications, endpoints, servers, services, and network devices. Simulations are agentless, can run continuously, and map to MITRE ATT&CK. Pentera Resolve prioritizes validated attack paths and supports remediation and retesting to check for reduced exposure. Pentera Peer provides an AI-native interface for analyzing adversarial testing, including natural-language queries about findings and validated paths. For production use, customer-controlled safeguards include throttling, impact limits, emergency stops, optional read-only modes, and audit logs. Listed integrations include AWS, Azure, GCP, Okta, Jira, ServiceNow, Slack, GitHub, CrowdStrike, and Microsoft Defender. Pentera says AI data is hashed and encrypted, not used for model training, and not retained by Pentera. The platform is paid, with pricing on request. Pentera was founded in 2015.

PurpleSharp is a free, open-source C# adversary simulation tool for Windows Active Directory environments. It generates attack telemetry for detection teams building and testing analytics, checking detection resilience, locating visibility gaps, and identifying event-logging pipeline problems. Documentation maps 47 MITRE ATT&CK techniques across execution, persistence, privilege escalation, credential access, lateral movement, discovery, and defense evasion. JSON playbooks can combine techniques, define variations, and set technique-specific parameters. Local simulations run interactively after copying the PurpleSharp assembly to a host. Remote simulations use Windows SMB and RPC, requiring administrative credentials on the target plus network access to TCP ports 445 and 135. Scout tasks retrieve audit policy, event subscriptions, PowerShell logging settings, processes, and services. ATT&CK Navigator layers can be exported or imported as JSON playbooks. PurpleSharp is self-hosted on Windows, requires .NET Framework 4.5, and is licensed under BSD 3-Clause. The latest documented release is v1.3 from August 2021.
