What it sells: Assail

What Ares does[1][3][4][5][6][7][9][10][11][12]
Ares uses coordinated AI agents to discover weaknesses and validate what an attacker could actually reach. It tests authenticated applications through the existing identity provider and tracks changes across known and shadow APIs. Ares delivers the evidence behind each confirmed risk.
What Reaper does[3]
Assail describes Reaper as built for military, federal, and intelligence missions. Assail has expanded Reaper's sovereign deployment architecture to AWS GovCloud and Google Cloud Assured Workloads.

What it sells: Levo.ai

What AI Firewall does[4][6]
Levo gives visibility into AI transactions across prompts, agents, tool calls, API calls and downstream actions. Levo applies AI-aware data protection inline to prevent sensitive data from being exposed through prompts or responses. Levo enforces boundaries on what agents can do, which tools they can call and what parameters they can pass, inline and in real time.
What Runtime AI Visibility does[7]
Runtime AI Visibility covers agents, MCP servers, LLMs and AI applications. Levo auto discovers external and internal LLMs, agents, MCP servers, AI apps, gateways, embeddings and vector stores. Levo maps who authorized an action versus who executed it and surfaces token scopes and auth states.
What MCP Discovery does[4][8]
Levo continuously discovers MCP servers and integrates with MDM and endpoint agents to build an inventory that includes location, owner and context. Each server is enriched with ownership, environment context and usage signals, then assigned a risk score. MCP Discovery deploys via existing MDM and endpoint agents, requiring no proxies or rewrites.
What API Inventory does[4][8]
Levo's API Inventory surfaces how each API behaves, where it exists and what it exposes. Levo autonomously inventories internal, partner, third-party, shadow and zombie API endpoints. Levo maps how sensitive data flows through the APIs it discovers.

About Assail

Assail sells Ares, an autonomous offensive security platform that tests applications, APIs, mobile apps and AI systems and shows what an attacker could actually reach.[1]

Assail says Ares continuously tests applications, APIs, mobile apps, and AI systems as they change. Ares follows attack paths, exploits weaknesses, and proves what an attacker could actually reach. Coordinated AI agents extend testing capacity, and Ares tests authenticated applications through the customer's existing identity provider. Ares also tracks changes across known and shadow APIs and delivers the evidence behind each confirmed risk.[3]

Assail describes Ares as combining autonomous red teaming, attack surface management, and Shadow AI discovery across web, API, mobile, and supported AI environments, with applicable MITRE ATLAS coverage. The Ares platform is powered by Assail's domain-adapted model for security reasoning and tool use.[3][7]

On deployment, Assail says Ares can run within the customer's own infrastructure, even in disconnected environments. With Assail Anywhere, the entire platform, including the AI model, deploys on-premises, inside isolated and air-gapped networks, in the customer's own cloud, or through Assail's SaaS. Assail has also announced that it expanded Reaper's sovereign deployment architecture to AWS GovCloud and Google Cloud Assured Workloads.[3]

Assail names Ares, Reaper, and Scorpion as the products taken to the fight. Reaper is described as autonomous offensive cyber operations built for military, federal, and intelligence missions.[3]

Assail publishes industry pages for manufacturing, financial services, federal and state government, automotive, retail, and defense. In manufacturing, Ares validates systems such as ERP, MES, PLM, supplier portals, industrial APIs, and connected products. In financial services, Ares validates APIs, payment rails, mobile banking apps, and open banking integrations. For retail, Ares validates e-commerce web apps, mobile shopping apps, loyalty APIs, and gift card platforms. In automotive it covers telematics APIs, OTA infrastructure, and mobile companion apps.[4][5][6][9][10]

Assail says its team brings 26 years of offensive security experience. Assail also publishes original research on attack techniques and the exploitation of AI and API surfaces. A customer, Branch, says Ares helps its security team increase penetration testing frequency and validate remediations faster.[1][2][3][4][5][6][8]
