Penetration Testing & Attack SimulationVulnerability Management
The NetSPI Platform
Human-led PTaaS with in-house testers, plus external attack surface and cloud exposure monitoring.
The NetSPI Platform Overview
What it does
The NetSPI Platform is a Penetration Testing as a Service (PTaaS) platform that runs pentesting, external attack surface management, and detective control validation against a single validated asset inventory. Its distinguishing mechanism is a staff of more than 350 employed pentesters rather than a freelance marketplace, working alongside AI automation that handles reconnaissance, scanning, and triage so that findings delivered to the customer are manually validated and carry proof of exploitation.
How it works
Customers register assets in a platform inventory that deduplicates records across integrated asset, identity, and vulnerability sources, and testers work engagements against that scope while findings aggregate in near real time with severity, impact analysis, and remediation instructions. Remediation retesting is scheduled from the same interface, and findings route into ticketing systems for developers. External attack surface management adds weekly discovery scans across IP addresses, DNS domains, open ports, and ASNs, look-alike domain monitoring, dark web monitoring, and weekly AWS and Azure configuration reviews. A Model Context Protocol (MCP) service exposes validated vulnerability and engagement data to agentic systems.
Credentials and traction
SOC 2 Type II attested and Cyber Essentials Plus certified, with CREST and CBEST accreditations covering penetration testing service delivery. NetSPI was named a Leader and Outperformer in the 2025 GigaOm Radar for Penetration Testing as a Service (PTaaS) and a Sample Vendor for PTaaS in the 2025 Gartner Hype Cycle for Application Security. Published customer stories cover Microsoft, Medtronic, Chubb, Trimble, Gong, and Global Atlantic Financial Group.
Key Capabilities
mapped to solution categoriesDelivers findings through a live client portal as testers discover them, with status, severity, and evidence, instead of a single static PDF at the end of the engagement.
Initiates penetration testing engagements through a platform interface without requiring a new statement of work for each test, enabling testing at the cadence of development releases.
Automatically re-executes test cases for specific findings after the reported remediation deadline, confirming closure without scheduling a separate engagement.
Manages asset scope definitions, scope change approvals, rules of engagement, and testing windows through a persistent platform interface rather than per-engagement documentation.
Delivers findings directly into developer ticketing systems (Jira, GitHub Issues, Azure DevOps) alongside standard pentest reports, enabling developer remediation tracking within existing workflows.
Continuously enumerates internet-exposed assets (domains, IPs, subdomains, certificates, cloud storage, APIs) using passive DNS, certificate transparency logs, and active probing, including assets outside the official inventory.
Tracks SSL/TLS certificate expirations, newly registered lookalike domains, and subdomain takeover opportunities (dangling DNS records pointing to deprovisioned cloud services).
Ranks discovered exposures by combining exploitability signals, asset business context, and active threat intelligence to produce an actionable remediation queue.
Enumerates and monitors the attack surface of subsidiaries, acquired companies, and affiliated brands, common gap during M&A activity when new infrastructure is inherited without full visibility.
