Hadrian vs NetSPI

Hadrian is an agentic AI offensive security platform that continuously discovers an organization's external attack surface and tests it for exploitable exposures. NetSPI sells pentesting as a service (PTaaS), attack surface management (ASM), and breach and attack simulation (BAS) as a service. CISO Tribune files both under External attack surface management, Breach simulation and automated pen-testing and Exposure prioritisation and CTEM.

Who it fits
From its own pages, Hadrian sells an agentic AI offensive security platform to modern security teams. Hadrian describes mapping the external attack surface of every company in a group, including new acquisitions and legacy infrastructure. Hadrian states that role-based access lets each subsidiary or business unit see and act on its own assets while the group security team keeps the full view. Hadrian says many customers use the platform as their continuous baseline and bring in manual testers for targeted deep dives. Hadrian is delivered from the cloud.Not written yet

What it sells: Hadrian

What Atlas does[1][4][5][6][7]
Atlas discovers assets, technologies and service points, then uses agentic AI to confirm which exposures are actually exploitable. Atlas runs passive scans every hour, and event-driven testing starts automatically when a new asset or change is detected. Atlas pricing is based on the total asset count. Atlas offers two add-ons at additional cost: mergers and acquisitions assessment and infostealers credential leak detection.

What it sells: NetSPI

What AI/ML Pentesting does[3]
NetSPI's AI/ML Pentesting includes expert LLM testing and jailbreaking. Microsoft partnered with NetSPI to build a standardized AI security testing framework for its 70+ products.
What Red Team Operations does[6]
NetSPI's Red Team Operations test security controls, policies, incident response and training. NetSPI partners with selected threat intelligence providers to test the resiliency of critical systems.
What Detective Controls Testing does[7]
NetSPI Detective Controls Testing validates that security tools operate effectively across endpoint security solutions, network security solutions, SIEMs and MSSPs. NetSPI's ransomware simulation pack covers TTPs and behaviors from real-world ransomware campaigns.
What Social Engineering does[6]
NetSPI's social engineering experts deliver findings from email, text, phone and physical scenarios. NetSPI runs custom phishing engagements to identify gaps in security procedures and technical controls.

About Hadrian

Hadrian is an agentic AI offensive security platform that continuously discovers an organization's external attack surface and tests it for exploitable exposures. Hadrian's Atlas and Nova products run on one platform, so exposures, pentests and evidence sit in one place. Atlas gives breadth across everything a company exposes, and Nova gives depth in the application that matters. Hadrian runs from the cloud and is ready in minutes.[1][3][4][7]

Atlas continuously maps a company's external attack surface and validates exposures. Atlas discovers assets, technologies and service points, then uses agentic AI to confirm which exposures are actually exploitable. Atlas discovers every domain, DNS record, IP, certificate, cloud service and app a company exposes, then tests all of it the way an attacker would. Atlas maps outward from the organization: subsidiaries and acquisitions, the domains each one registered, then every subdomain, IP, certificate and cloud host under them. Atlas starts from a few apex domains, maps how everything connects, flags what changed and proves which exposures are real. Atlas runs passive scans every hour, and event-driven testing starts automatically when a new asset or change is detected. Atlas matches a new CVE to the assets running the affected version, tests every one of them, and tells the customer which are really exposed.[7]

Hadrian's Orchestrator AI uses machine learning and pattern recognition to scan the internet for exposed assets tied to an organization, including Shadow IT. Hadrian continuously scans the internet to find forgotten subdomains, cloud instances and legacy servers that belong to an organization but are not in its official inventory. Hadrian's platform safely simulates real-world attack techniques to validate if a vulnerability is actually exploitable in the customer's specific environment. Hadrian only flags verified risks that have a confirmed path to compromise. Hadrian's agents safely test what they find and only raise what holds up, with the request, the response and the fix, and they check the fix when a risk is closed.[7][8]

Nova is an agentic penetration test powered by AI that performs the same techniques a skilled human pentester would, including reconnaissance, exploitation and lateral movement. Nova's agents sign in as every role, learn how an app's business logic works and chain small steps into real impact. Nova's testing stays within the scope the customer sets, at the pace the customer chooses, without changing a single record. Nova customers receive access to the Hadrian platform to see results and get a compliance-ready pdf report. Atlas's asset discovery and exposure mapping feeds directly into Nova, so penetration tests are automatically scoped against the real attack surface.[4][9]

Hadrian's hacker agents test the external attack surface continuously, chain what they find into attack paths, and report only the paths they can prove. Hadrian does not replace a scoped red team exercise, and internal networks, social engineering and physical access stay with the customer's human red team.[10]

Hadrian maps the external attack surface of every company in a group, including new acquisitions and legacy infrastructure, and starts testing it as soon as the deal closes. Hadrian uses ownership signals from DNS, certificates and registration records, and a customer's team can confirm or correct attribution in the platform. Role-based access lets each subsidiary or business unit see and act on its own assets, while the group security team keeps the full view. Hadrian connects to multiple cloud environments with a few clicks, providing a centralized view of exposed assets. Hadrian identifies exposed cloud assets and misconfigurations that could enable lateral movement and privilege escalation. Hadrian's ML algorithms prioritize risks based on business relevance, asset attractiveness, discoverability, impact and exploitation ease.[12]

Hadrian allows teams to assign leads, share risk details with third parties, track remediation progress and collaborate in a shared space. Hadrian's risk details include severity, impact, proof of concept and remediation steps.[1][3][9][13]
