More About Nisos
Nisos provides managed intelligence services that support enterprise security, trust and safety, fraud, and risk teams in monitoring and responding to digital threats across external environments. Its offerings are structured to extend internal Security Operations (SecOps) with analyst-led collection, investigation, and reporting focused on adversaries, not only internal telemetry. Organizations use Nisos to identify and understand threat actors targeting their employees, executives, brands, and customers, and to connect that understanding to operational security controls and response workflows.
The company’s services System Integration Testing (SIT) within the broader security and risk management stack, adjacent to categories such as threat intelligence (security analytics), digital risk protection (DRP), external attack surface management (EASM), and incident response (IR services). Nisos analysts aggregate data from Open-Source Intelligence (OSINT), technical infrastructure telemetry, dark web sources, and social and collaboration platforms, then apply investigative methods to attribute or characterize actors, campaigns, and infrastructure. This work is usually delivered as a managed service rather than a standalone software platform, and is designed to integrate with existing Security Information and Event Management (SIEM), Security Orchestration Automation Response (SOAR), case management, and ticketing tools via reporting, APIs, or workflow alignment.
Typical enterprise use cases include executive and workplace protection, doxxing and harassment investigations, IP theft and data leak investigations, account takeover and fraud schemes, phishing and malware infrastructure mapping, and monitoring for coordinated disinformation or brand impersonation campaigns. Nisos teams often align investigations with frameworks commonly used by SecOps and threat intelligence teams, such as the MITRE ATT&CK framework (threat intelligence), kill-chain and campaign analysis models, and standard incident response processes. Outputs include detailed reports on threat actor tactics, techniques, and procedures (TTPs), infrastructure linkages, likely objectives, and recommended mitigation or enforcement steps.
From a marketplace taxonomy standpoint, Nisos fits within Managed Security Services (MSS), threat intelligence services, and digital risk protection. Its work is typically consumed by CISOs, SecOps leaders, trust and safety teams at platforms and marketplaces, corporate security and executive protection units, and fraud and risk leaders in financial services and other regulated industries. The focus on attribution, adversary research, and investigative reporting positions Nisos for environments where organizations need human-led analysis to complement automated security tooling, especially when threats involve complex online ecosystems, cross-platform harassment or abuse, and financially or ideologically motivated threat actors.
